The plim curculio has not yet suffered any severe setback by ",inter
conditions in the Geor-ia fruit belt. Unusually large nuoers -'-nt into
hibernation throughout the entire eastern o?.rt of the United States.
The soiraea aphid is more abundant in Florida this year than it
has been for several years. Citrus growth is retarded, so there is pros-
pect of d--r.-..-e from the aphid this sorin.

Florida J. R. Watson (February 18): '.ireworms are moderately
Mississippi R. 17. Harned and assistants (February 22): W'e have re-
ceived reports of damage to sweet potatoes from several
California B. 0. Essig (February 24): viireworms are moderately
abundant. They have been reported from many sections
WHITE GRUBS (Phyllophaga spp.)
Ohio J. S. Houser (February 16): We expect considerable
damage this year.
Indiana J. J. Davis (February 24): White grubs were abundant
in sod in 1927 and beetles were numerous in 1929 in Starce
County. The grubs will doubtless be abundant and de-
structive in north-estern Indiana in 1930.
Iowa C. J. Drake (February 25): Brood A is due to appear
Texas F. L. Thomas (February 25): T7hite grubs are moderately
abundant at College Station.
JAPA.IZSZ BLTLL (Popillia japonica NTe-m.)
General U. S. sept. Agr. Press Release (February 24): The
Japanese beetle quarantine regulations have been revised,
effective Varch 1, 1930.
The most important changes are the extension of the
regulated area to include one county in 1iassacl'usetts as
well as certain new territory in oMecticut, & York,
Pennsylvania, Maryland, Delaware, and Virginia, rnl the
division of the regulated area into 4-enerr.'lly :n. lightly
restrictions on tne interstate movement of farm pro-
ducts will apply to t:ie generally infested area out '"ill
not affect the movement of farm products from the lirl'tly
infested areas. Regulations governing the interstate ship-
ment of nursery and ornamental stock, and of sand, soil,
earth, --eat, compost, and manure, will ap-Iy to sii<>xnts
from the generally infested area to the li'-tl _.if3ted
areas cs -,ell as to shiments from eit:ier to points o.-
tirely outside the regulated areas.
ASIATIC BETLE (knomala oritntali i "aterh.)
ASIATIC GARLE:T' EZTLi (Aserica castane;-a Arrow)
General U. S. Dept Agr. Press Releac- (Fu7ruary 21): As a rsu-lt
of the observations Of the past y-ar, the.. :c.rtment of
Ariculture has reached the conclusion that a continuation
of Ftedral restrictions on the interstate movement of nur-
sery products and soil, to prevent the sprcai of these in-
sects, is not justified by the information at hand. In
placing the quarantine a year a-o, the department felt that
dissemination should be prevented until the significance of
species could be-"cighed .more carefully and further observa-
tions made. The pst .year's -"ork has indicated that their
potential danger to the United States does not justify the
expenses of quarantine administration and th losses re-
sulting from the impQsition of restrictions.
Florida J. R. Watson (February 18): Cutworms are moderately
Mississippi R. -7. Harned and assistants (February 22): f fev cut-
7'orms have been observed in Monroe s:i Tate Counties.
Agrotis ypsilon Rott. is moderately abundant in the vicinity
of Laurel, there it is attacking cabbage, puas, and other
Hawaii D. T. Fulla-ay (1929): The army-"orm Scodo-tcra mauritia
Boisd. has been scarce since the introduction of natural
enemies, but the true "pokos' cutwormss), "hich hide in the

been unusually destructive this year on the .ral:a ranch. lands
of ha-aii, according to the reports of Mr, A. Carter,
manager of the Parker Rancn. The -"orst drought experienced
in thirty years "as reported at the same time.
0. H. Sweezey (1929): Army-'or-s (Aletia uni-nuncta -ar.
and Spodootera mauritia 3oisi.). T.ere -r. less t.:an the
usual n'umbur of out.reaks of ar.7-orrus in c ne fields t.-is

had little to do with the nun':r, as the greatest number
wgs present on a soft maple very near to the 7oods, while
the smallest number was on a maple stan;ir.i on the far side
of the house from the woods. These numbers are nrob'-bly
smaller than is actually the case, since undoubtedly :.anv

0. 1. Snano (February 5): The average pcrccnta;;e of scale
alive on a number of limbs from a -ocach orc-arJ at e .ueen
was found to be 21.8. The heavy mortality is attributed to
low temperatures. A minimum of-5 F. 7as recorded at one

A GEASSHOPPSR. (Conocen halus spltator Sussure)
Hawaii J. F. Illinc,-orth (1929): T:- lon-horned grasshoper
Conocephalus saltptor Saussure is normally a predacious
species, feeding upon mealybugs and other insects. During
the summer, these grasshop-oers occurred in tremendous numbers
in fields adjoinin- -rsss areas. In such locations they
fed rather extensively upon the tips of pineapple leaves.
A more serious damage, however, was done by the females
inserting their egrs into the calyx cavities of flowering
fruits. -,here the ovipositor punctured the tissue, some
decay was initiated.
A BUD ,:OTH (Pyroderces rileyi Walsingham)
Hawaii J. F. Illingworth (152): This insect is troublesome on
the fruit. The em7s are laid on the blossoms, and the
caterpillrs live inside the calyx cavities. They feed
upon the remains of the stamens and pistils, -now'*ing them
right down to the point of attachment. In some c'ses e
breaking do;.n of the fruit is caused by or anisrr.s of decay
entering through the wounds opened up by the caterpillars.

J. R. ".atson (February 19): A checlc-up on the cane borer
during the harvest time of cane showed t'i.at it was unusually
scarce over 7!st of the State. Severe infestations were
confined to the southwestern counties in re-ions where d..a-.e

Louisiana ,Z, E. Hinds, C. E. Smith, and N. Allen (February 22): The
sugarcane borer population in hibernation was reduceJ greatly
by the unusually severe cold of .ece.ber and -Jnuary hn
the larvae were destroyed in the frozen cane. It looks now
as though there v:ill probably be an unusually smnr.all first
generation of borers.

Hawaii 0. H. Swezey (1929): Tie status of this rEst remains ciout
the same from year to -year. It is generally v:ell controlled
by the Ye'- Guinea tach aid in a considerable part of the
suercane areas, but has done appreciable dama'-e in certain
districts -.here conditions are specially favorable to the

additional infestations of cypress berk scale, a serious
cvoress pest, have been found in the Covina-Pomonpi district
as the result of survey v'ork carried on by the Los An-eles
County Azricultural Commissioner's office. This scale rs

The recorded activities of this nest in other -rts of the
State show it to have been severe in the San 7ran:iz'o 3a"-

the interior of a room in the Agricultural Building on the
campus of the University of Nevada. They v'ere comin.- into
the room through a small crack in the cement flooring. It
is impossible for us to tell you at this time whether the
termites were attzickin- the buildin- or whether any dama-e

R. '7. Earned (February 25): At the present time probably
1 per cent of the area in Mississippi is infested '.-ith the
Argentine ant. However, it is doubtful if sny. other insect
causes as much annoyance to oeoole in Eississioui "-ith t'..
possible exception of mosquitoes. and house flies. Th amount
of loss and damage that it causes in the State each -'ear
probably exceeds that of any other species with the exception
of the boll ':ee'il, boll worm, ter-ites, and possibly a few
M. R. Smith (February): The follovine.nev:'infestations have
recently been found: Hoffman, Holmes county ; -ossville, leake
County: near Jackson, Hinds County. Argentine ants have been
observed "'orkin7 outdoors at an air temeratnure of 41.' F.
At this temperature the ,orders were barely mo.in- on a tree,
or in other words only covering a distance of 1 foot in 245
seconds. This is the lowest termnerature at which we have so
far found them active. They are very commonly found worlinf-
at all temperatures in the fifties, but of course at cor.e',hat
slow,:er rates than at hijh,-r temperatures.
L. J. Goodgame (February 22): Argentine ants are feed in-
well now. They are giving considerable trouble in homes in
G. L. Bond (February 22): Argentine ants were four
crawling around on concrete walks in Ellisville while the
ground was frozen.
2:. R. Smith (February 20): An observation made on a
colony of Argentine ants nestinF in a lo at Starksville
showed that the ants can stand temperatures as low as 10 0.
without suffering any noticeable mortality. Hundreds of
specimens found in crevices beneath the loose bark of the
log and surrounded by particles of frost quickly revived
when brought to a warm room. 'Observations on a number of
Ar,_entine ant colonies at Starksville show that certain birds
have been dig.ing into the nest and feeding on the ants at
various times during the Tinter. The exact species of birds
feeding on the ants has not yet been learned.
FIRE' A'T (Solenopsis geminata Fab.)
"..'m. L. Gray (February 24): Fire ants are very abundant in

I,. Smith (February 20): number of people in various
localities in the state have complained of fire ant workers
emerging from crevices around the hearths of their fireplaces
and getting into clothing, food, etc. :h-se ants often nest
in cracks in the masonry or woad'cork of houses, and for that
reason infest houses even during the coldest 7,eat'her in ,:inter.

Argentine ant poison.
