THE MORE IMPORTANT RECORDS YOR AUGUST, 1932
With the harvesting of early small grains the grasshoppers have concentrated on tax, late small grains, alfalfa, and corn., and caused considerable losses in certain areas in the Northwest. During the month, over part of the territory, parasitic flies appeared to be reducing the infestation.
White grubs are generally abundant from New England to Kansas, with local serious damage.
Hessian fly surveys in the Middle Atlantic, East Central, and 'Jest Central States indicate that there will be heavy infestations on early planted wheat in Western Maryland, Pennsylvania, Ohio, Indiana, Illinois, eastern Kansas, Uissouri, and northeastern Nebraska. The situation is more threatening than it has been in many years over most of the Winter Theat Bolt.
The chinch bug was retorted doing considerable injury in the vicinity of La Crosse and along the Mississippi River in Pierce, Pepin, and Buffalo Counties, Wisconsin, and Lake, Itasca, Hennenin, and Goodhue Counties, Minnesota, this region being very much north of the normal chinch bug belt.
A severe outbreak of fall anrmyw7orm was reported by wire on September 2 from northwestern Texas.
The corn ear worm is generally prevalent throughout the greater -oart of the United States and, as usual, causing considerable damage to both sweet and field corn. In New Jersey it was observed attacking celery, an unusual food plant for this insect.
The European corn borer was found early in the month in the suburbs of
Racine, 7is. It appears that the infestation located last August in Sheboygan and Manitowoc Counties has been cleaned up.
The cotton leaf worm has not yet appeared in the South Atlantic States, nor as far north as Arkansas. This is unusually late for the appearao.nce of this insect.
The codling moth is reported as from abundant to very abundant throughout the greater part of the country. In Illinois it has been more abundant than at any time during the last 10 years.
Uith the short crop of peaches the injury to the fruit by the oriental
frt oth has been, uch more serious than usual and the insect seems to be on t:c increase throughout the idd4le Atlantic, Southl Atla:itfc, And East Central States.
Blister beetles arc doing very considerable damage to a great variety of crops from Yew England westward to Nebraska and Kansas.
Potato leafhoppers with the associated hopperburn are appearing in numbers in the northern Middle Atlantic States, westward to Minnesota.
The potato psyllid with the associated psyllid yellows is quite prevalent in parts of Colorado and Utah.
Thae Mexican bean beetle has been reported for the first time from New York and Czberland Counties, Maine, and from Bennington and Rutland Counties, Vermont, these being the northernmost records for the spread of this insect. It
was also recorded from southwestern Nebraska, this being the first record the Survey has received of this insect in that State.
The harlequin bug is generally prevalent considerably north of its normal habitat.
The elm leaf beetle is being reported as prevalent from New Enhgland and New Yor]k, and local outbreaks have developed at Knoxville, Terz',, and Parma, Iddaho.
The gladiolus thrips is quite generally reported as damaging gladiolus
flowers from New gland throughout the Middle Atlantic States and in Tennessee and Minnesota.
Forty-one cases of Rocky Mountain spotted fever have been reported from MI ryland and Virginia during this year up to August 17.
JAPATESE 3~L= (Popillia japonica Nbwm..)
Connecticut. W. E. Britton (August 23): This pest is gradually spreading and
will soon be found throughout the State. Repor'ted at Bridgeport attacking
rose, grape, and many trees, shrdbs, and plants.
Pennsylvania. L. B. Smith (August 26): The Japanese beetle is causing heavy
damage in Philadelphia; Bucks, Montgomery, Delaware, and Chester Counties;
confined to suburban Philadelphia.
New Jersey. R. C. Burdette (July 25 and 25): Japanese beetles are causing considerable damage to asparagus in the Woodstown-Swedesboro section.
Maryland. Washington Times (August 8): A number of young apple trees stripped
of foliage and some damage to bearing trees in an orchard near Frederick
Georgia. 0. I. Snapp (August 2 and 5): The bird grasshopper, Schistocerca
americana Drury, had done considerable feeding on the foliage of peach trees
during the first week in August. The damage was confined to those orchards
near sodded fields. Poison bran was used as a control. (Peach County)
Indiana. H. 0. Deay (August 26): Local outbreaks occurred in southern part of
the State and at Culver in the northern part during the first part of the
month. Millions of Melanoplus differentialis Thos. had moved into orchards
and corn fields at Vincennes, July 30,and had damaged one year old apple
trees seriously by August 6. Very serious in alfalfa at Culver, Auarast 3.
In Vanderburg County, which is in the extreme southern part of the State, one
correspondent estimated that 90 per cent injury had been done to corn. However, most of the grasshoppers had been killed by a fungus disease b7r the
middle of the month.
Michigan. R. H. Pettit (August 22): Grasshoppers are very bad in the upper
Peninsula, and they are bad in the upper one-third of the lower peninsula.
Wisconsin. E. L. Chambers (August 22): The heavy rains have tended to reduce the
numbers of grasshoppers and many of them have been killed by parasites and
Minnesota. A. G. Ruggles and assistants (August): Grasshoppers were still very
abundant during August over most of the infested territory, although they were
decreasing very rapidly where poisoning was carried on. (Abstract, J.A.H.)
North Dakota. F. D. Butcher (August 5): With the small grains ripening and being
harvested, the hoppers are concentrating on flax, late oats, alfalfa and corn.
A lot of corn is being damaged by having the silks cut before the grain has
A. D. Collette (August 13): Most damage from grasshoppers done in sandy rie in southeastern and eastern parts of Steele Countyr. Very little damage done in north and northeastern part of county. Daiag.e spotted in some places 100

South Dakota. H. C. Severin (Augu.st 23): Two small colonies of the Mormon
cricket found, one at Bee Heights and the other at Murdo.
WEITE. GRUBS (Phyllophaza spp.)
Vermont. H. L. Bailey (August 22): White grubs are very abundant, damaing
potatoes in the western part of the State.
Pennsylvania. J. N. Knull (August 10): About 80 per cent of the conifers planted
near the Cole House, Perry County, were killed or injured by white grubs.
L. 3. Smith (August 26): White grubs are very abundant locally throughout
Ohio. E. W. Mendenhall (July 30): The white ,rubs are exceedingly abundant and
are doing considerable damage to strawberry plants and in some cases have
totally destroyed whole plantations in the central counties of Ohio.
Illinois. W. P. Flint (August 19): White grubs are causing very serious injury
in the northern part of the State, the infestation this -ear bein; caused mainly by grabs of Brood B. The whole area is quite -enerally and heavily infested with the small grubs of Brood A. As both broods will be working
-in the soil during the early part of next season, we e-pect very serious
damage from these insects in that part of Illinois in 1933.
Wisconsin. C. L. Fluke (July 27): White grubs are very abundant. Brood A began
hatching the first of July.
Minnesota. A. G. Ruggles and assistants (Auru~st): White grubs were quite
serious in Ramsey County, badly damaging golf courses and strawberry plantations. This insect was also reported as very abundant in eastern Polk
County, but from scarce to moderately abundant over the remainder of the State.
Missouri. L. Haseman (July 27): Great numbers of nearly mature grubs, especially
in sod ground at Columbia.
Nebraska. M. H. Swenk (July 20 to August 25): White grubs are moderately injurious in blud-grass lawns and strawberry boaeds durin- the noriod here covered.

HESSIAN FLY (Phytophag7a destructor Say)
Pennsylvania. H. E. Hodgkiss (July 26): Hessian flies are very abundant and
dan.age is very severe.
L. B. Smith (August 26): Hessian flies are moderately abundant in southeastern Pennsylvania.
Illinois. W. P. Flint (August): The regular Hessian fly survey carried on
cooperatively between theNatural History Survey and the Federal Bureau of
Entomology has just been completed. This year there has been a very marked
increase in infestation throughout the central and southern parts of the State.
Through A. J. Surratt, Agricultural Statistician, Bureau of Agricultural
Economics, U. S. Department of Agriculture, a special report on Hessian fly
conditions was received from 680 of the regular crop reporters located in all counties in the State. These reports of damage and no damage to winter wheat
may be taken as an additional check on the conditions found in our regular
survey. This increase in fly infestation was mainly due to weather conditions.
The fall of 1931 was extremely favorable to an increase and this was followed
by especially favorable weather during the egg-laying period of the spring
brood of the fly. The heavy spring brood resulted in serious damage to spring
wheat, this brood coming from wheat that was sown early in the fall of 1931, and also from volunteer wheat. At the present time there is an abundance of volunteer wheat in practically all sections of the State. The fall brood of the fly is just starting to emerge and lay eggs. If the present rainy, warm
period continues the fall brood of the fly should all be out by the normal safe sowing date. If September is dry, emergence will be somewhat delayed
and eg laying will probably take place a few days after the normal fly-free
date. In any case the infestation is so heavy in most parts of the State
south of a line drawn through Carroll, Ogle, and Kane Counties that with anything like normal weather conditions early seeded wheat is sure to be heavily
Est Central States. C. M. Packard (August): The area covered by this report
includes Tennessee, Kentucky, Ohio, Indiana, southwestern Michigan, and souther
and eastern Illinois. There was serious injur- of the 1932 crop in many
Illinois and Indiana fields, some beinj practically a total loss. Infestation
was comparatively light and injury negligible in Kentucky, Tennessee, and
soutlrestern Michilan. Fly abundance was variable in Ohio, being greater in the nort crn and west-ceritral parts where heavy, infestations were prevalent,
though not of sufficient intensity to reduce yields seriously. The outlook
for fly injury this fall in Ohio, Indiana, and Illinois is the most threatening
in years. Practicall- ever, stubble field contains enough puparia to be a potential source of heavy infostation in any early fall-sown wheat near by.
While the percentage of parasitized -puparia is hi-gher than usual in Ohio and Indiana, viable puparia are still very abundant in the stubble. The prospect
is loss threatening in Kentuck, Tennessee, and southern Michigan but with fall
weather favorable to its activity the fly is likely to cause material injury
to the 1933 crop in these States also. The following table summarizes the records on which this report is based. Field samples consisted of 50 stems and plot samples of 100 stems, the 'avcrtgc infestation in each sot of plots
being used as a single field. THe figures below are entirely our own but the
report of the Ohio State Hossian fly survey has been referred to in su arizing
the situation in that State.

West Central States. J. R. Horton (August): This report is based on a survey
during June and July covering Kansas, Missouri, Nebraska, and Oklahoma,
exclusive of areas beyond the present range of serious Hessian fly outbreaks.
Severe damage, resulting in partial to complete loss of the 1932 winter wheat
crop of many fields, was done by the fly in Missouri, southeastern Nebraska, and some counties of north central and northeastern Kansas during the season
1931-'32. Infestations were comparatively slight And crop reductions relatively unimportant in southern Kansas and northern Oklahoma. The prospects of fly injury to the winter-wheat plantings of the coming fall are unusually
threatening in Kansas, Missouri, and Nebraska, except in the frontier areas
of occurrence already mentioned. Most of the Missouri counties inspected
and most of the normally fly-populated counties of Nebraska are strewn with
heavily infested stubble fields. The same is true of some of the counties sampled in northeastern and central Kansas; while even those of the southeastern portion of this State have a scattering of sufficiently infested
fields potentially to give rise to outbreaks in neighboring fall-sown wheat.
Although the percentage of parasitized puparia is greater than usual over most of these areas, there are still sufficient numbers of living Hessian fly larvae present to'favor ready emergence and plentiful egg deposition in
the fall. The outlook is not serious in the northwestern portion of Kansas,
where the fly rarely becomes abundant, but even in that section there is a
very noticeable increase of puparia and sufficient population now present for
potential local outbreaks following weather favorable to fly increase. The prospects for northern Oklahoma are good in -that the summer infestations are
slight, except locally in the extreme northeastern portion. The attached
table sumarizes the results from which this report is drawn and includes records from a total of 930 samples, 565 of which-were our own; 270 were
supplied by the Nebraska experiment station, 76 by the Missouri station, and the remainder by the Kansas station. A large proportion.of the samples were
of 50 stems each; the rest of 100 or more stons each'

INSECT CONDITIONS IN PUERTO RICO DURING AUGUST, 1932 G. N. W mlcott
Insular Experiment Station, Rio Piedras, Puerto Rico
A survey of the status of the cottony cushion scale, Icerya purchasi Mask., conducted during the middle of August shows that it is now less abundant ini citrus groves than at any time since its *discovery, and difficulty is experienced in finding suitable localities for the liberation of lady-beetles.
Every caterpillar collected from nearly 3,000 pods of lima beans maturing during June and July at Isabela was Etiella zinckenc" I Treit. They averaged 37 caterpillars per 100 pods, a few of them being pai;J.tized by Heterospilus etiellae Rohwor.
A'heavy infestation of the "pulga Americana" (~y~'na basalis J. Duv.), normally a flea-beetle pest of tobacco, has been noted on swectpotato at Rio Piedras, at least half the superficial leaf area of vines at one end of a field being eaton by these beetles.
The sweotpotatoes were also heavily infested with C-I. formicarius Fab.,
the adults of which feed from the under side of The le c -s c petioles, midribs,
*nd the larger veins. This insect has also been reported as attacking cotton seedlings in a field possibly half a mile away from the sweetpotato field.
Despite the very imperfect clean-up of cotton fields last year and the
small area planted to cotton this year on the north coast, infestation by the pink boll worm (Pectinophora gossypiella Saund.)is very low by the middle of the picking season, no infestation of more than 10 per cent being noted in cnumerous fields examined between Isabela and Arecibo on August 4, and in two fields no infested bolls were found.
