INTR0UO T D
With the last number of Volume 6 of the Insect Pest Survey Bulletin,
we instituted a slight change in this publication by issuing a 10th number
in which the year's entomological features were summarized. This was the result
of many requests for an annual summary similar to the bne prepared in 1922 and
published in the form of a Departmental Bulletin (TU. S. D. A. .To 1103).
It -as felt impractical to issue a printed annual summary, as the necessary
time involved in preparing, editing, and printing such a publication made it
available at so late a date that much of its value was lost.
This year the Sur-ey will issue to its collaborators a questionnaire
form covering several of the most -idely distributed and important insect pests,
rith the hope that this may result in the Survey receiving from those carrying
on investigations on one or more of these pests, data of a much higher statistical
value, and of a more comparable nature than could be obtained by cursory re-
ports. The Survey does not -ish its collaborators, ho-ever, to feel that the
incidental notes on all insect conditions made in the course of their regular
activities are not highly appreciated by the Survey and urges its reporters
to continue their general reporting to as -reat an extent as their time will
The season in general is hot far enough advanced to have developed any
outstanding features at the time this first number of volume 7 is issued.
G EMBAL FE' 7TTS
G.R SSH:FFTs (Acridiidae)
W. B. Mabee (February 15): Last fall, in a survey of the
eastern part of Montana bordering South Dakota, especially
Wibeaux and Fallen Counties, considerable nzr.bers of e-gs
were found of iYlanoplus atlanis PRiley, Car-nula -el`.ucida
Scudd., and 'elkrnorlus bivittatus S-3 There is likely to
be a small grasshopper outbreak in this territory.
T. D, Urbahns (F'ebrun-ry 17): Grasshopp'rs covering such
species as llelanoplus diffarentialis Thos., `>mnala pellucida
Scudd., 'Ielanoplus marginatus Scud d. ,.ea anolr.s 6evwcstator
Scudd,, and others, have caused less destruction of crops
than in previous years on account of the large quantities
of poisoned bran mash which have be-n used by ,-ro-'3rs through-
out the State.
I:O':0:T CRICKET (Anabrus simplex Hald.)
w. B. IoLbee (February 15): Our big problem this co-inz season
7ill probably be the 2ormon cric1-et. In Lake eni Sanders
Counties, in the western part of the Stvte, this i-Isect no-
infests some 250,000 acres, or at least double the territory
infested the previous season. 'ring the season of 1336
it did damage ,rorutinz to over 13j,C,2. A survey lant fall
shoved that an unusual n-inber of es-7 a7cre played and e.fs
collected since oi-ir recent cold Teather hive hatched normally,
so unless something uforecee-, happens, we e:qmect quite a
problem on our hands this coming sri.'g. Through this Deo.rt-
meit a-nd ith the use of thre Cou-ity Insect Pest Law 1e expect
to sen.d. somee ..000 on the control canairp.
7I7 .-PlS ('lateridae)
B. B* abee (February 15): Wireworms are gradually increasing
and -re ever becomi:ig a s.ore serious problem, especially
"'ith our Zotto g-o-7er-.
S3 A L A ID F OR A E- C R 0 I 1' S C I S
HE-!.J'" Th ('-'.,-~o~~.i destructor Say)
C. C. 7-1i and H, %ith (b.--r- 3): The 'h.t stu':ble
is verv li,'-tly i fecte: 0. tlie c-rin :.b -r-tion of the
f.1. 7o Tli..nteer "heat was found to be leitiful and in
.:.ieral he'vi"'. ilf yted. -- .... tion .has shown thpt cueria
in the -",olunt.er v-hrnt .. .'-.,rv lightly p1rasitized ,n- for
this reason may 2re-,? a source of considerable infestation
We s t NVirginia
during the coming season. For the most nart the fall wheat
was lightly or not at all infested, 7rith the exception of that
in certain localities along the Susquehanna Valley, "here infesta-
tion was very heavy.
H. E, Hodgkiss (February 16): For the last five years, including
1926, the Hessian fly has not been abundant in Pennsylvania except
in 1922. Since that time the Hessian fly has decreased so as to
be a relatively unimportant consideration. In 1926 the spring
brood was large, but the damage r'as not extensive. The records of
our planting demonstration plots for 1926 indicated that there w7as
little infestation in these pIlots at the time of sampling.
C. C, Hill and Hi. D. Smith (February 3): Stubble over the entire
State was found to be very lightly infested, and the fall -"heat
was for the most part sown late and escaped infestation. Volunteer
wheat, however, -'as found plentiful through most of the State and
was in genr,-l heavily infested. The fly puparia in the volunteer
,-heat proved to be lightly parasitized and may become a source
of considerable infestation during the coming year.
H. D. Smith (February 3): Wheat stubble and fall sown wheat w7re
found very lightly infested. There is considerable volunteer
--heat in the fields which was found to be moderately infested. The
puparia in the volunteer wheat wereonly lightly parasitized.
Z. ,- Rumsey (February 18): 'This insect was not reported to us
H. DO Smith (February 3): Both wheat stubble and fall sown -heat
were found very lightly infested. There was not sufficient volun-
teer wheat to be a factor for Hessian fly infestation.
J. 0. Pepper (February 21): There have been no complaints about
the Hessian fly in the past two years and no specimens have been
collected during this time.
J S. Houser (February 11): There is some prospect of damage by
the Hessian fly in Ohio this coming year, particularly in the
west-central part of the State where the -heat-field survey last
season indicated that about a dozen counties "-est of Columbus
were rather badly infested, A more disturbing factor, holvever,
is the fact that over much of the wheat-producing section of
Ohio harvest was delayed by wet weather to the point here the
grain shattered badly. The fall months were un--isu-nlly wet and
this resulted in the shattered grain sprouting, and since clover
is a very poor stand we have much more volunteer wheat than is
normal, Much of this volunteer wheat which "-e have examined is
heavily infested and gives promise of furnishing quite a heavy
I. H. Pettit (February 11): Just now the Hessian fly is present
in only a scattering way in Hic-iigan, so far as I kn.ow
S. B. Frc-:ker (February 18): Fare, no reports in 1926.
7. P. Flint (February 15): Moderately abundant in volunteer
wheat in most areas in the State. Volunt-er 'heat is present
in nearly all stubble fields. There "ill be some infestation
from this source in the spring. ITearly all sown wheat -a-s planted
very late, but in most sections of the State but few fields
-ere sown before the fall rains, and a little infestation exists
in the so-'n -.7heat. The few examinations made show that the fly
survived the winter.
H. C, Severin (February 12): The Hessian fly ras ver7 scarce
in South Dakota-during the past j'ear.
UH. S-enk (February 10): In a general way -e 1-no- that the
esszian fly is not particularly nu->-Lrous in the -inter -heat
fields at this time, and 1e do not anticipate much, if any,
commercial damage to the winter wheat crop of 1927.
J. 7. -cColloch (February 11): There is a rather general in-
festation of the Hessian fly over much of the State, and in some
of the south-central counties, such as R:1ing.n, Reno, ?ni Pratt,
there has been some loss, due to this insect. Throughout most
of the State, ho,-ever, the infestation is 'c"cc-7ratively light &
but promises to increase this spring.
C. 3. Sanborn (February 11): The Hessian fly is more abundant
than usual and has increased the area of infestation over any
year prec?'i- It now extends as far south as the southern
bound--r-- of Payne County, and. as far -est as 8 miles -est of
Alva. The north est mart of the State, '''herein the infestation
lies, is not unifor-ly infest-.'. Some infestations are heavy,
C. 3. Rude (February 14): Early planted -heat in 7ools, Alfalfa,
Grant, &hzs, GarfieldC, :oble, and ?yae Counties is quite heavily
infested. In Garfield County fully 50 per cent of the crop is
infested. Greater ab'_nd-nce as compared with an average year.
Five sar-ples of IC0 plants each fror2 five points in fields showed
infestation running from 0 to 95 per cent.
W. B. Mabee (February 15): The Hes iaan fly, which came into
iontana a fe, years a:,o, has -auctically disapwe-ire1.. In a
survey last fl of the 1:,. --'ously i~ifestc.i territory, I could
find no signs of it. It "Us ap-3 -ently receded from uonta".
T. D. Urba-'ns (February 17): The H essian fly has been reported
active in the fields since Janxary b7, Mr. C rt-riCibt of U. S.
Bureau of Entomolor, hile'li.ght infestations ere known to
occur in the upper Stctqjiterito Valley bnl the Coast districts.
This insect is of economic importance only in the regions
immediately adjoining the lower Sacramento River and San Francisco
TOOTHED FLEA BE3TLE (Chaetocnema denticulqta 111.)
M. H. Swenk (December 31): During the third week in October from
Hamilton County there came a report of an abundance of the toothed
flea beetle feeding on young wheat.
GREPTF BUG (To:xoptera graminum Rond.)
Michi ga n
W. EP Rumsey (February 18): We received no reports of outbree:s
by this insect last year.
J. 0. Pepper (February 21): On January 10, specimens of this
insect were received from Oconee County and reported as destroying
a two-acre field of oats. It possibly occurs in small numbers
elsewhere in the State but has not been observed or reported.
BR. H. Pettit (February 11): The green bug did some damage in
'ichigan for the first time last year. It was more troublesome in
the far north than anywhere else, although here and there quite
ood sized areas suffered.
J. NM. Robinson (February 11): The green bug was not observed last
fall or this spring in Alabama.
R& W. Earned (February 21): The green bug is seldom a pest of
importance in Mississippi, So far this spring we have received
no reports about it.
W. F. Hinds (February 17): The green bug is apparently unusually
abundant- this spring, .
So B. Fracker (February 18): Serious damage in some fields in
Ashland, Bayfield, Clark, Florence, Oconto, Taylor, Racine, and
St. Croix Counties in 1926.
H. C. Severin (February 12): The green bug was fairly abundant
in South Dakota during the last year and did some harm. It is
only occasionally that this insect is found in our State.
M. H. Srenk (February 10): No infestation of the green bug hae
come to our notice during the past fall or winter.
J. W. LicColloch (February 11): As far as our records go the
green bug has not been reported in the State this fall br winter.
C. E. Sanborn (February 11): The green bug is again prevalent
and has been prevalent all winter. Some known infestations occur
in Canadian and I'ingfisher Counties. A few specirmnns have also
been taken in Payne County, but no p--rticular field infestations
have been report:i.
C. S. r'ude (February 14): Tie -reen bug shored up in Love County
much earlier than usual. In no case is it "idely scattered, it
being still found in small patches. Also reported from Canadian
and Kingfisher Counties.
F. L. Thomas (February 17): We have recently received information
with reference to the occurrence of the -.repn bug in Wise County.
T7. B. Mabee (February 16): Nearly every year ve have one or two
more or less local outbreaks of the greern bug in the lower Arkansas
Valley. It seldom is very serious, doing its damage mostly to oats
but sometimes to heatt also.
A. A. Nichol (February 15): The green bug is present in the Salt
River Valley but there are no records of injury, and grain crops
are seemingly in excellent condition.
T. D. Urbahns (February 17): The green bug is found only upon
careful search by a specialist, and is not considered of economic
E. 0. Essig (Febru-.ry 23): Uoticed last winter but not this.
CHII'CU BUG (Blissus leucopterus Say)
H. E. Hodkiss (February 16): The chinch bug ordinarily is not a
pest. There was an outbreak in 1926 in three counties rather
widely separated. The cause of this outbreak was not clearly
ascertained. It did not gain serious proportions.
"7.. E. Rumsey (February 18): No outbreak of this insect 'as reported
to us last year.
J. 0. Pepper (Februnry 21): This insect ras present the past year
in rather large numbers in a number of localities of the".Piddmont
Section of the State. It caused very serious injury to late corn,
In York County, a few small areas of late corn -ere completely
destroyed. Apparently a large number went into hibernation and
so far we have not had any very severe weather this winter. To
survey has been made to check up on the number surviving the
E. -. Berber (February 24): This insect is kno'n to be present
in the St. .u-stine *rass Inrns but does not apncar to be active.
The chinch bug, to my obser--ttion, doe- itsworst injury in the
St. Augustine grass la'7ns during the fall or during the drier
spells in late sumrner.
R. H., Pettit (February 11): The chinch bug is present in small
numbers, in the southeastern part of the State only.
S. B. Fracker (February 18): Very rare, no specimens collected
for several years.
W7. P. Flint (February 15): Present in numbers sufficient to cause
damage in a few southwestern or southwest-central counties.
R. W. Earned (February 21): During the summer of 1926 the chinch
bug appeared in injurious numbers at several places, but was not
reported so frequently as during the two preceding summers. Te
have no reason to believe that this insect will be abundant during
W. E, Hinds (February 17): The chinch bug is not often abundant
enough to cause any complaint.
H. C. Severin (February 1P): The chinch bug has been reduced to
such numbers through weather conditions that it is agin negligible.
M. H. Swenk (February 10): The chinch bug,we --now, went into the
winter in abundance in a large district in southeastern :Tebraska.
We have planned to investigate to determine the approximate winter
mortality, which we suspect may run fairly high, but as yet we
have not been able to mo-e the necessary survey.
J. W. McColloch (February 11): The chinch bug situation is rather
alarming. More bugs went into hibernation this fall in the nonth-
eastern fourthh of the State than at any time in the last ten years.
Climatic conditions have not caused any high mortality, and because
of snovs and rpins it has not been possible to carry on as much
burning as was formerly done. In view of these facts, it would
appear that the chinch bug will be a major problem '-ith us during
the coming season.
C. S. Rude (Fabru-ry 14): In northeastern Oklah6ma chinch bugs
can be found in the bunch grass but Pt present there is nothing
to indicate that they will be more numerous than usual. Winter
burning of waste land '"as practiced in localities where the bugs
'ere abundant last year.
C. Z. Sanb6rn (February 11): The chinch bug infestation this
year will probably be similar to that of last year.
T. D. Urbahns (February 17): Thile recorded from California, it
apparently does not make its aUpeerance in the field, and I do
not recall ever having'an infestation in this State of the true
form, Blissus leucopterus. ,
E, 0. Essig (February 23): So scarce that it can not be found for
CO02T AR "'.CI.-M (Heliothis 0bsoletq Fab.)
T. C. Barber (February 21): EBastinl ears for sale in the local
city market at Broimn^lle are heavily attached by the corn ear
worn] The -'orms are of all sizes from very small to large, indicting
a continuous winter development of the species.
ALFALFA .ATE.. ILLA (Z,>r:us e'rnthe:ni Boisd.1.)
T. D. Urbahns (Febriary 17): This insect '-.s not so abundant during
the season of 1926 as it has b:n for a nlr.brr of years -ornvious,
although this insect constantly cau-ed heavy losses to alfalfa
growers extending from the Irre)crial Valley in the southern part of
the State through the San Joaquin and Sacramcnto Vall:y1s to the
G? 7 T CLOVER 70' (Plathypana scabra Fab.)
Mississippi R. 7. Earned (February 5): During the lattc-r part of January moths
of the green clover r-orm 'ere recei-ed from luka in Tishoming0
County, and Sibley in Adams Couity, and also vere observed flying
here at A. & M. College.
G-r'T_ JTJI: BEETLE (Cotinis nitida L.)
-7. A. Thorn:s (January 20): Sc'cral rcsii?:ints of this to-rn have
complained of something destroying their la-n grass within the
past few days. An e-,i':i otion of so:e lawns has beEn made and these
were found to be heavily infested -ith -hite grubs. In some places
the grass was almost completely covered "ith the loose earth brought
to the surface by the grubs. The nc'-ly opened burrows are very
conspicuous early in the mornings and give the lan an unsiyitly
appearance. This is the heaviest infestation the writer has observed
in this section (Thadbourn) and should it continue through spring
serious damage is almost certain to occur.
FR U I T I ':T S E' T S
i. S. Hough (February 16): Aphis eggs are more abundant on apple
twigs in the orchards of northern Virginia than has been observed
in this coctlon (Winchester) for the past five years. Although
the winter has been very mild, no eggs have shown the outer shell
cracked at the time of this writing.
CODLING MOTH (Carpocapsa pomonella L.)
W, P. Flint (February 15): Recent -::-rnnations in southern and
-estern Illinois by Mr. Chsn'-er anc n'. Bigger show that a high
percentage of overwintering larvae have survived. In many orchards
large numbers of larvae are fotind on the trunks of trees, and from
present indications, we can expect serious trouble with this insect
again in 1927, provided the season is at all favorable.
T. D, Urbahns (February 17): The codling moth has been unusually
destructive in view of the lo7 prices of apples and the lack of
proper and thorough spraying by many apple growers. In the pear
districts this species is more readily controlled, although the
total losses to pear growers -ould run into many thousands of
SAN JOSE SCALE (Aspidiotus perniciosus Comst.)
W, E. Britton (March 1): The San Jose scale is not an important
pest in commercial orc'Lrds where dormant sprays are given onqe
in three or four -ers. 7e find it occasionally on neglected
trees but even there it does not seem to be injuring then seriously.
A. E, Stene (Iarch 2): We have not observed any alarmingly large
infestations of this insect. We come across it occasionally, but
there is no indication that it is any more numerous than it has
been for the last few years.
P. J# Parrott (February 14): This species plays a very insignificant
role at present. During the fall of 1926 there -ere mailed to us
at different times specimens of apples which sho-ed infestation,
and we observed the scale also during the summer of that year on
three-year-old plantings of apples, some of the trees of which were
badly infested. Generally speaking, the pest is of no importance
in commercial orchards. It is rarely mentioned at meetings of
fruit growers and we are seldom called upon to give recoir-:en'.2tionS
relative to control measures. Commercial growers are no longer
apprehensive relative to its activities, and if spotting of fr-tit,
especially apples, is noticed, they know how to handle it effe-tively
without calling on S tate agencies for assistance.
T. L. Guyton (February 16): The San Jose scale seems to be less
abundant than last year. This is just a general impression
gathered by the men as they go about, both in the nursery inspection
and in the handling of fruit, particularly apples. We have made
no official count.
H. E. Hod L-is (February 16): The San Jose scale is not a State-
wide protiz-r, in Pcnnrlv.-ania. There are only a few isolated or-
chards where the sale has increased to any extent. There are
some indications of increased development where spraying has been
poor, othb--ise the scale is an unimportant consideration.
H. L. Dozier (February 14): The San Jose scale has not been a
factor in Dcla -ire orchards for a number of years. At one time
in the nineties it was considered our worst and most menacing
problem, but now, either because of the more or less systematic
spraying of the orchards or else through the agencies of natural
parasites, this scale is no longer a serious thing with us. In
fact only occasionally does it show up abundantly enough to require
P. Do Sanders (February 25): The San Jpse scale is on the increase
in 1laryland. This noticeable increase can be traced to two general
tendencies in the State for the past few years,
1. The commercial fruit gro-ers are making an effort to reduce
the cost of production by spraying for the scale every other
year. As a result considerable fruit injury was noticeable last
fall in the commercial orchards.
2. Poor spraying by the small orchardists has allowed the scale
to increase. This is especially true in western M4ary~and where
the small orchard is most abundant.
We E: Rumsey (February 18): The San Jose scale occurs throughout
the State but is kept down by the regular spray program of the
orchardists. It still does itsdamage on fruit trees in village
lots and hom-e orchards that are not properly cared for.
J. 0. Pepper (February 21): In the Sand Hill or northeastern
section of the State an unusual infestation of scale occurred
on peach trees this winter. In many orchards parts of trees have
been killed. From all observations it appears that lubricating
oil emulsions as well as lime sulphur te failed to control.
Iluch effort is bein.- put forth to kill the scale out in this
section with this yeerb dormant spraying.
Monthly Letter of the Bureau of Entomology, 1;o.152 (December,1926):
Observations in the past few months have shown a very heavy
mortality of the San Jose scale in the Georgia peach belt; heavier
than at any other time in the last five years. It is believed
to be due to twice-stabbed ladybird beetles. In many cpses the
scale coverings with no bodies under them were found clinging
to the trees. The question has arisen whether the unusual abun-
dance of ladybird beetles in 1926 is in any way correlated mith
the general use of lubricati.ig-oil emulsions for the last several
E. W Berger (February 24): The San Jose scale is present but
I am not aware that there hn.- been tnrthing unusu-1 in its
J. S. Roiuser (February 11): The San Jose scale, from reports received
this winter and on the basis of some observations made, is perhaps
only slightly more abundant than last year. On the whole, I think
it can be stated that the standard controls recommended are effectively
holding the insect in check where the spraying is properly done.
Moreover, natural controls are operatingquite effectively in many
sections of the State and the scale does not seem to be making great
progress even where no dormant spraying is done.
W. P. Flint (February 16): The winter survival is apparently about
normal. Examinations made during the last month of unsprayed material
show ffom 30 to 45 per cent of the scale alive. These examinations
would apply in general to conditions in southern Illinois. Very few
badly infested orchards can be found in our larger orchard district;
owing mainly to the general use of emulsions for scale control.
R. H. Pettit (February 11): The San Jose scale is not making itself
an outstanding pest at all. As a matter of fact, me hear a very
little about it these days, perhaps because delayed dormant spraying
is being pretty universally done.
So B. Fracker (February 18): Not now known northwest of Madison.
Injurious in Ozaukee and Kenosha Counties. Has been brought under
satisfactory control for the present by spraying in Racine, Walworth,
and Dane Counties.
H, C, Severin (February 12): The San Jose scale made i-appearance
in South Dakota on several different occasions during the past
fifteen years, but each introduction was destroyed through burning
of infested stock.
M. H. Swenk (February 10): No infestations of the San Jose scale
have come to our notice during the past fall or winter,
C. S. Rude (February 14): The San. Jose scale is widely scattered
over the State and as yet the farm people are not taking hold of
clean-up measures readily.
C. B. Sanborn (February 11): The San Jose scale is more generally
prevalent than common and did more damage last year than during
many preceding years.
Alabama J. M, Robinson (February 11): The San Jose scale was present in
about the usual abundance over the State.
R. 7. Harned (February 21): The San Jose scale is not fairly abundant
in every county of Miississippi. It -ould- probably be difficult to
find an orchard of deciduous fruit trees that is not more or less
infested. The fruit trees growing in practically every town and
village in the State are also more or less infested. The commercial
orchards and many of the home orchards are sprayed regularly each
winter with a lormant spray, and uhder such conditions the scale
is of little imrDrtance. Although the San Jose scale is probably
our most important fr-it-tr2e pest, -e find that most of the trees
are able to survive many years eve-n thoup infested with this insect.
Of course, young small trees that become infested frequently succumb,
but after the trees have survived to an age of three or four years,
they are usually able to survive for a much longer period. These
trees, of course, are probably not so vigorous and profitable as
trees that are sprayed and kept practically free of scale insects,
but I have on numerous occasions, observed trees to remain infested
with the scale for many years and continue to bear quite profitable
crops from year to year. It would seem that in many cases this is
due to partial natural control of the insects combined with the
resistance of the trees. Our nurseries are kept free of the scale
and no trees are allowed to be sold under any conditions that show
scale markings. As a precautionary measure all deciduous trees are
fbmigated with hydrocyanic-acid gas, but any that show scale markings
must be discarded,
W. E. Hinds (February 17): The San Jose scale is undoubtedly serious
wherever it occurs, and we have no doubt that it had continuous
breeding through the winter season.
C. P. Gillette (February 16): 'e have had no inquiries concerning
the San Jose scale during the past year. We know, however, that the
scale does occur in some of the orchards in the vicinity of Grand
Junction, and probably there is some extremely slight infestation
in one locality in Delta County, but for the past t'70 years we have
been unable to find any specimens of it at all. In the Grand Junction
area we try to treat promptly every orchard where an infestation
occurs, but have never been quite able to stamp the insect out.
It does very slight damage to the fruit crop in this State,
C. Wakeland (February 15): Severe infestations of the San Jose scale
on fruit trees occurred only on trees in areas where there had been
a small percentage of the insects that survived the winter of 1924-
25. These areas were known and spraying was carried on generally
in restricted communities in the spring of 1926. As reported in 1926,
very little dormant spraying ""as done in the spring of 1925, and it
was not needed, for the winter preceding had killed the insects
completely in the fruiting areas of and on all portions of the trees
above snow line. Killing was so complete that in large areas there
has not been sufficient increase of scale insects to justify the
application of dormant sprays again in 1926. There are a fer localities
even "'here it appears that spraying will not be conducted this
season, so complete w"as .the destruction of scale insects in December,
1924. During the past season a noticeable increase has taken place
in all areas -here there as a slight hold-over of live insects
in 1924-25. In many localities there was little or no injury to fruit
during 1926, but the insects are scattered in the fruiting areas
of many trees now where they are not suspected by the grower, and
doubtless heavy injury will occur in mrny localities this
season sci leps n'tAol 7i0371'7 i S--cticd ThCe -inters of 1925-

PE'CH T7IG OREF.R (Anarsia lineatella Zell.)
T. D, Urbahns (February 17): The peach t-ig'borer is probably
the insect of greatest economic importance in California in
view of the immense production of canning and shipping peaches.
There are two and three generations in different parts of the
State, and the destructiveness of this insect is extended
throughout the entire interior valley district as well as southern
CLOVER i'ITE (Bryobia praetiosa Koch)
T, D. Urbahbns (February 17): The clover mite, k1no-n locally as
the almond mite, is especially destructive on almonds and prunes
throughout the Coast districts and interior valleys of northern
and central California.
APRICOT SCALE (Lecanium corni Bouche)
Tq D. Urb-hns (February 17): The brown apricot scale continues
to develop in abundance on prune trees in most of the przune-
gro-ing districts and on apricots --herever they are gro'h through-
out the State. Peach, pear, and plum trees also frequently
become infested to the extent of requiring special control measures.

on January 29 as follo-s: "Last year we set out 1,000 pecan
trees of which 146 died. On removing these for replacement it
was found that although the tops were dead, the roots of the
majority of them appeared to be alive and this kind of worm was
found ih the trunk at the ground surface." The specimens that
accor,-poe-ied this letter --'ere idIentified by Mr. J. :. Langston

of pecan was more -idespread and more serious during 1926 than
during any previous" year. Of course, other insects may have
caused part of this injury. *7e have no definite data to indicate
what' species of insects -ere concerned in causing this injury,
but assign it to Uezara viridula as that species usually gets the

T. D. Urbahns (February 17); iMealybugs. of several species,
including Pseudococcus citri Risso, Pseudococcus maritimus
Ehrh,, Pseudococcus gahani Green, and others continue as serious
pests of citrus trees, while they are also causing considerable
loss to grape and pear gro-rers. In addition to this, they are
considered of cco.-iomic importance to ornamental nursery stock.
SCALE INSECTS (Coccidae)
T. D. Urbahns (February 17): Citrus scale insects, including the
gray scale, Coccus citricola Champ.,the black scale, Saissetia
oleae ?arn.,the red scale, Chrysomphalus aurantii I'ask., and
others continue to be very destructive throughout r:-any of the
orange and lemon districts. In some districts control is reasonably
successful by the use of oil sprays, while in others double
treatment by both spraying and fumigation is necessary.
SPIRA3A APHID (Aphis sniraecola Patch)
J. R. Tatson (February 15): Citrus aphids, -hich were getting
very numerous in December, received a severe setback in January
through the killing of all tender foliage by: the severe freezes
of that month,. Most of them starved to death through lack of
food, However, they are rapidly increasing and. give Dromise cf

EUJROPEAN RED SPID2 (raretetranychus pilosus Can, & Fanz.)
T. D, Urbahns (February 17): The European red mite, known
in California as the citrus red spider, is generally dis-

the fruit trees through some of the southern counties and
in the San Joaquin Valley. It is frequently found present
in rather abundant numbers.
FIG SCALE (Lepidosaphes ficus Sign,)
T. D. Urbahns (February 17): The fig scale is gradually

called to Lucedale in George;.County to investigate insects
that --ere d-'-',--- :ing turnips. Besides the turnip louse I found
D. duodecimpmctata eatii;- some of the turnips. The Trorst

3. iabee February y 15): Another serious insect problem in
this State is the mosquito in the northern section, principally
in 31aine, Phill-;s, and Valley Counties. Mosquitoes of several
species, including Aedes vexans Yi., .ee ec nigromacula2 e. luil.
.,?,e-' curriei Colq. and many others are so abundant that 1'Jor
will not work in the hay fields and it is practically i -.pcssible
to use work horses or to keep dairy cattle in 'this area. It is
really a very serious economic problem. "e expect to de'ote a
considerable ar:ou1-it of time to this situation next yer.

ANGOUJiOIS FRLrT IU:T: (Sitotroga cerealella Oliv.)
Monthly Letter Bureau of Entomology Yo. 152, December, 1926:
Perez 'ir-ors reports that recently he and G. "7. Ellington dis-
covered that the ,angoumois grain moth larvae sometimes leave
the grain and spin cocoons in the ground. This is a new fact
that appears never before to have been recorded.
A SMALL i2,TH (Blabophanes crocicapitella Clemnr)
Perez Sim-mons (Ja!-uvry 23): Small, very active moths flyin- in
a house were found to come from an infestation of case bearers
feeding on dry onion skins in the bottom of a box of onions, at
Tako-ia Park. This clothes-dnoth-like species has been recorded
from birds' nests and dried white potato (August Busck) and from
absinth seeds and refuse (';.T..i.Forbes: Lepidoptera of Ne-' York).
Forbes gives the distribution as "1:'-T York to California, proba-
bly general: also in Europe and Ha-aii."
R. W. Harned (F-ebruary 25): Argentine ant infestations have
recently been found at tv'o nel-I localities, Bond and Greenvrood
Springs. All ant determinations are made by 1i. R. Smith.
FIRE AJT (Solenopsis geminata Fab.)
R. 7. Harned (February 25): 7,e are recoivinJ many complaints in'
regard to the fire ant, Solenonsis -crinIatn Fab. These ants build
their nests in ..-ardcns and caure trouble by their habit of taking
the small seeds of recently planted vegetables, by their attendance
on plant lice, and specially by their pugnacity. In infested gar-
dens :,hen v getables or berries arc gathered, these ants come from
their nests in th, soil ot the base of the plants and get on the
hands of the o-'ncrc -,here they sting viciously. In a recent letter
from Fayette it is ctatcd that an ant probablyy this species)
enters the pipr.ed e--s 0of eege and kills the 'con__ before they
emerge from the eggs.
