THE MOLE IMPOLTMT RECORDS POL AUGUST, 1933

TNe /grasshopper situation in the Northern Plains States continued serious through August. Populations are heavy over ouch of this territory and unless unfavorable weather conditions prevail next spring the outlook for destruction hy grasshoppers next year is ruore serious than it has been any previous yean of the present outbreak. Outside of this most heavily infested territory grass- hoppers me re reported as unusually abundant in parts of Virginia, Oklahoma,

Nevada, Arizona, and Utah.

Important infestations of mormon crickets mere reported from parts of Montana and isolated localities in Nevada., Utah, and North Dakota.

The fall aroyworn appeared late in the month in Arkansas, Mississippi, and Texas. In Mississippi heavy damage mas reported from several sections of the Stake.

Brood* -A of the unite grubs mas rather heavily infesting pastures in Indiana, Wisconsin, Minnesota, Iowa, and Missouri.

The .Asiatic garden beetle mas more abundant this year and injury much more extensive than during any previous season in the N cm York - Nem Jersey area. Another scarabaeid, $ erica similis Lewis, was taken for the first time at Mill Neck, N. Y.

In this number of the Survey Bulletin are summaries of the^ Hessian fly sur- vey in Ohio and Illinois. The infestations are much lighter than l?»st year, being 8 per cent in 1933 and 34 per cent in 1932 in Ohio, and 3.76 per cent in Illinois in 1933 and 29 per cent in 1932.

The chinch bug appeared during the month in large numbers in parts of New England and. Pennsylvania, far east of its normal habitat. It also continued to be unusually abundant north of the chinch bug belt in Michigan, Minnesota, and I or/a. Within the chinch bug belt heavy populations ~ere appearing from Ohio to Missouri indicating large numbers of bugs to go into hibernation and the possi- bility of outbreaks next year.

The corn ear worm mas quite generally reported as destructively abundant a . i throughout practically the entire territory east of the Locky Mountains. Along the Middle Atlantic and South Atlantic seaboard damage mas quite generally severe,

GENERAL FEED E.-R S GRASSHOPPERS (Acrididae)

Virginia. The Evening Star, Washington, D. C. (July 15' : A farmer on the Spring Hill road, near Staunton, reported that grasshoppers have practically destroy- ed three fields of clover and that huge swarms are infesting farms in that section, cutting off the growth on an 18-acre two-field planting of new clover at the ground. Reports have also come that grasshoppers have attacked timothy hay and have spread to gardens and elsewhere in that vicinity.

Illinois. W. P. Elint (August 22): Very little grasshopper damage is reported from any part of the State.

Kentucky. M. L. Didlake (August 25): Grasshoppers are very abundant. There are complaints of injury to dahlias and zinnias everywhere around Lexington.

North Dakota. J. A. Munro (August 21): A survey ma.de through Cass and Richland Counties August 8 and 9 showed that Melanoplus bivittatus Say constituted about 20 per cent of the injurious species; the balance consisted largely of M. mexicanus Sauss. and Camnula pellucida Scudd. In 1952 the distribution of species differed in that M. bivittatus constituted between 85 and 90 per cent of the population and the balance were other injurious species.

Iowa. H. E. Jaques (August 23): Grasshoppers are unusually scarce in most of the State .

Minnesota. A. G. Ruggles (August 21): Egg laying in process. The weather is ideal for grasshoppers. No appreciable crop loss has been reported. One hundred carloads of bait have been used, as compared with 500 last year, showing that the 2 years of campaign kept grasshoppers under control.

Wisconsin. E. L. Chambers (August): Grasshoppers are very abundant in northern and central Wisconsin.

Tennessee. G. M. Bentley (August): Grasshoppers are scarce. Relatively fewer individuals than normal are present at this time.

Oklahoma. C. F. Stiles (July 27): Grasshoppers are quite numerous in some places in the southwestern part of the State, but I have been unable to check up on the damage to date. They are moderately abundant in western Oklahoma.

Nebraska. M. H. Swank (August 21): Grasshoppers are moderately aoundant, mostly in central Nebraska. Reported from Greeley, Dawson, and Lincoln Counties during the period July 20 to August 21.

Montana. A. L. Strand (August 19): The migratory grasshopper, M. mexic arrqs, has increased this year to outbreak numbers over large areas, especially in north- ern and eastern Montana. About 30 counties are facing severe outDreaks mr the coming season.

Colorado. G. M. List (August 24): The grasshopper infestation has been ratner spotted, there- having been no really serious outbreaks, but the infestation in the foothills region east of the mountains, is heavy enough to call for considerable control work.

226-

Nevada. G. G-. Schweis (August 21): Grasshoppers of several species have been

troublesome in widely scattered areas in Nevada, doing much damage to alfalfa and grain. Control measures were necessary in some instances, and the hoppers took the bait readily, resulting in a good kill.

Utah. G. F. Knowlton .(August 18): Grasshoppers are damaging young fall wheat at Mt. Pleasant and Minersville .

Arizona. C. D. Le'oert (August 26): The pest of primary concern this month is grasshoppers. We have had the most severe infestation this year that has aver been recorded in this State. M. mexicanus was observed early, in fact as early as April this hopper was observed mating in the fields. Consequent- ly, during the last half of May and extending well into the. month of June there was a very heavy infestation of this species in the Salt River Valley. Drastic control measures were immediately put into effect. But beginning the latter part of June and extending through July the large differential grass- hopper, M. different ialis, became very abundant in practically all areas of the Salt River Valley, especially in the Glendale, Laveene, South Tempe, and Mesa areas. Then at the peak of the differential grasshopper development another brood of M. mexicanus became abundant. Several fields of cotton have been completely destroyed, as well as several plantings of hegari.

Many alfalfa fields have been stripped and much garden stuff has been ruined.

New Mexico. . J. R. Eyer (July 24): M. f emur-rub rum DeG. is moderately abundant in the northeastern part of the State.

Oregon. D. C. Mote (July 25): M. sal tator Scudd. was reported as damaging a mint field at Jefferson July 10.

J. B. Gill (August 22): Lubber grasshoppers are moderately abundant at Tifton,

Missis sippi. C. Lyle and assistants (August): Lubber grasshoppers are moderately abundant at Ocean Springs.

-g MORMON CRICKET ( Anabrus simplex Hald.)

North . Dakota. J. A. Munro (August 21): Many specimens have been received from various parts of the State, with one report of crop injury from Burke County.

Montana. A. L. Strand (August IS): Important infestations occur in four

different sections of Montana as follows: Pryor Mountains and Wolf Mountains in Big Horn Comity; Dryhead district in Carbon County; Sanders and Lake Counties; Little Rockies in Blaine and Phillips Counties. The Pryor Mountain, Wolf Mountain, and Dryhead infestations are by far the most important, and a campaign against the crickets is being organized for next season.

Mississippi. C. Lyle (August 23): Severe injury to young corn at Poplarville, Pearl River County, was reported on July 26. Since that time, reports of heavy' damage to young corn have been received from several sections of the State. Luring the past few days specimens or authentic reports regarding their occurrence have been received from LincLoln, Sunflower, Monroe, and Okt ibbeha C ount ie s .

Texas. P. L. Thomas (July 29): Grass. ■worms appeared very scatteringly at College Station on July 22.

VELVET3EAN CATERPILLAR (Anticarsia gemmatilis non.)

Florida. J. R. Watson (August 24): The velvetbean caterpillar appeared in Polk County in July and in Alachua County in early August. It is not as yet very abundant in the latter county.

WHITE GRUBS ( Phy 1 1 op haga spp.)

Indiana. J. J. Lav is (August 29): White grubs were reported very abundant in sod at Eobart , July 30 .

Wisconsin. E. L. Chambers (August): White grubs are very destructive to corn, oats, and pasture lands in the southeastern part of the State from Marinette County southward through Waushara County to Vernon County.

C. L. Fluke (July 25): Brood A white grubs are doing considerable damage to pastures in southwestern Wisconsin. Population studies show from 200,000 to 800,000 per acre. Larvae of brood C pupated by the middle of July.

Minnesota. A. G. Buggies (August 21 ): White grubs are very abundant .

Iowa. H. S. Jaques (August 23): White grubs are showing up and causing severe damage to lawns, pastures, etc., in some localities in the areas usually harboring brood A.

decreased rapidly at the end of July, and in August were reduced so much that relatively little, if any, damage to vegetation appears to have "been done. Compared with most years, the infestation this summer was quite light in most places. Larvae which hatched from eggs laid during the present season appear to be of about the same numerical strength as at the corresponding time last year. Rainfall during the present summer has been copious and has provided conditions much more favorable to larval survival than was the case in the summer of 1932, when the prevailing drought appears to have been the prime factor in reducing the adult beetle population to the low point witnessed this year. ‘The importance of wind as a factor in promoting the spread of the Japanese beetle was emphasized by the discovery of numerous beetles washed up .along the south shore of Long Island as far east as Fire Island. As far as known, these beetles were all dead. Large numbers of beetles were also found washed up along the south shore of Delaware Bay, of which some were alive.

This observation shows that a body of water as wide as Delaware Bay would be only a partial obstacle in checking the spread of the beetle.

Maryland. E. N. Cory (August 22): Infestation in the sprayed area is much lighter than last year. There is a marked difference in the condition of spra,yed and un sprayed foliage,

ASIATIC CARDEN BEETLE (Autoserica castanea Arrow)

New York, New Jersey, and Pennsylvania. C. H. Hadley (June): This insect is more abundant than last year, and the grub injury has been much more extensive than during any previous season. The most serious plant injury occurred in the unemployment gardens (76 acres in all) distributed throughout Nassau County. There were large areas in several of these gardens where it was impossible to grow any vegetables until after the grub stage was past. There has also been garden injury in private gardens (ornamental and vegetable) in Nassau and Westchester Counties. The injury was heaviest in gardens which were in sod last year, but there was also heavy plant destruction in gardens which had been under cultivation for several years. In surveys made for the Japanese beetle the following distributional records for A. castanea were obtained; at the Boaderwood Coif Course at Rydal, Pa.; in Eairmount Park, Philadelphia, Pa.; at the St. Davids Coif Course near Wayne, Pa.; at the Seaview Golf Course near Atlantic City (Atlantic County), N.J. (August 22): On Long Island it has also been causing for the first time extensive injury in vegetable gardens, especially to bean, beet, cabbage, carrot, eggplant, kohl rabi, parsnip, pea, pepper, and turnip.

Rhode Island. A. E. Stene (August 21): One specimen has been captured in a trap in Westerly.

JAPANESE SERICA ( Serica. similis Lewis)

HESSIAN FLY (Phytophaga destructor Say)

Ohio. T. H. Parks (August 24): A survey of 26 counties shows the present

infestation to he slightly more than 8 per cent, compared with 34 per cent infestation in 1932. The infestation ranges from 2.4 per cent in Drake County to 15.6 -per cent in Clinton County. There was no serious damage to any wheat in 1933/

Illinois. W. P. Flint (August): The results of the Hessian fly survey for August are as follows:

MEAT MIDGE ( Contarinia tritici Kby.)

Ohio. T. H. Parks (August l): We have received a sample of wheat from Eairfield County with so many of these larvae in it that the owner feared to store the grain. Prom the numbers of the larvae present the insects must have damaged the milky kernels and reduced the yield. Ho general outbreak of the wheat midge occurred in Ohio.

BLACK GRAIN STEM SAWFLY ( Trachelus tabidus Fab.)

Virginia. J. S. Pinckney (June): Slight infestations of this sawfly were found in the Counties of Louisa (2 per cent), Spotsylvania (1 per cent), Essex (l per cent), King George (l per cent), Richmond (l per cent), Westmoreland (1 per cent) , and Fairfax (1 per cent) . Other counties in the principal wheat- growing areas showed no infestation. Injury to wheat from this source was obviously negligible. The survey was based on the examination of 5 widely distributed samples of wheat stems from each County.

Maryland. J. S. Pinckney and E. J. Udine (July): Infestations of the black grain- stem sawfly were found in the Counties of Baltimore (11 per cent) , Carroll (4 per cent), Frederick (5 per cent), Earford (2 per cent), Howard (2 per cent), Montgomery (6 per cent), and Washington (2 per cent). Injury to the wheat crop from this source was negligible. Five widely distributed samples of 50 wheat stems each from each county formed the basis of this survey. This is a noticeable increase in infestation over last year, when no sawflies were found in the course of a similar survey.

Pennsylvania. C. C. Hill, J. S. Pinckney, and E. J. Udine (June - July): Infes- tations in wheat were found in all sections of the State surveyed for this pest. In many fields the grain was conspicuously knocked over from this cause, with the accompanying loss of wheat usually experienced by lodging.

Each sample examined consisted of 50 stems. The infestations by counties

Ohio. T. H. Parks (August 24): The chinch bug is very abundant.

Illinois. W. P. Flint (August 22): Weather conditions have been highly favorable for the development of chinch bugs throughout central Illinois. In most cases the rainfall has been below normal and temperature conditions about normal.

This has resulted in a heavy second brood of the bugs. At present more or less serious damage is occurring in about 60 counties, with prospects for a still greater population next year.

Michigan. E. I. McDaniel (August 9): The chinch bug continues to appear in the southern two tiers of counties of Michigan.

Wisconsin. E. L. Chambers and assistants (August): 'The chinch bug is very abundant in Pepin County.

Minnesota. A. G-. Haggles (August 21): The chinch bug is very abundant in a few counties.

The second generation is scattered very widely, and around 25 to 30 counties in southern Iowa are infested. Extensive burning campaigns have been planned for this fall,

Missouri. L. Hasama*- (August 23): The chinch bug situation is alarming. The

summer generation of young is very abundant on corn, even feeling in sweet corn ears at Columbia,

Kansas. H. H. Bryson (August 21): Chinch bugs are not so numerous at Manhattan as might be expected at this time of year, if one compares the present abundance with that observed at harvest time.

Oklahoma. C. E. Sanborn (August 22): Chinch bugs are abundant in some localities,

South Carolina. 0. L. Cartwright (August 21): Bella moth larvae are doing noticeable damage to seedpods of Crotalaria at 'Florence.

SOYBEANS

VELVET3EAN CATERPILLAR ( Anticar sia gemmat ilis Hbn.)

Louisiana. W. E. Hinds (August 29): A. gemmat ilis is stripping soybeans in a few areas in southern Louisiana and mots (probably migrated specimens) are being found at Baton Rouge and at other points farther North. We find that the eggs of this species are being attacked by Trichogramma, as we would expect them to be. The highest parasitism found thus far is^amopg Anticarsia eggs laid on soybeans planted in a cornfield where we liberated Trichogramma for the control of Diatraea saccharalis Eab. The colonization was made on August 5, and on August 24 95 -per cent of the Anticarsia eggs were found parasitized.

SUGARCANE

SUGARCANE BORER ( Diatraea saccharalis Eab.)

Louisiana. W. E. Hinds (August 29): Sugarcane borers are increasing quite

rapidly with the beginning of the fourth generation now underway. Heaviest infestation is restricted to comparatively small areas and is not general. Trichogramma mi nut am Riley parasitism in borer eggs is manning somewhat below the general average for this date a year ago but colonization is showing a distinct advantage as in previous years.

FRUIT INSECTS APPLE

CODLING MOTH ( Carpocausa pomonella L.)

South Carolina. W. C. Nee ties (August 21): Very severe damage is being caused at Clemson College by the third brood; previous damage was light.

Ohio. T. H. Parks (August 24): The codling moth is more troublesome than usual. The season has been very favorable to the insect, and a few orchards which have suffered damage in the past have more worm entrances than in former years. This is apparently due to the use of calcium arsenate in the second-brood spray. Some orchardists who followed a very complete and careful spray program are experiencing serious trouble with late entering worms. The out- break is largely limited to Lawrence County and to orchards along the west end of Lake Erie.

- 237-

In di ana. J. J. Davis (August 29) : Codling moth has had. -unusually favorable conditions the past season and has "been most difficult to hold in check.

Huge 'losses have resulted.

Illinois. W, ?. Flint (August 22): The codling moth is still extremely abundant. Large numbers of moths are now being taken in bait traps, both in southern and central Illinois. The hatch of worms will certainly continue up to and probably beyond September 1.

Wisconsin. C. L. Fluke (July 25): The codling moth is moderately abundant. The second brood began emerging the middle of July.

Missouri. L. Haseman (August 23): A very heavy moth emergence has been on since August 15. Late worms are a real problem throughout State. Control is quite satisfactory, however.

Kansas. K. H. Bryson (August 21): An examination of banded apple trees at the College Horticultural Farm at Manhattan August IS revealed as many as 150 larvae per tree. The infestation at this farm is very much greater than last year.

Nevada. G. G. Schweis (August 21): The codling moth is very abundant at Reno. Practically all unsprayed fruit is infested.

Utah. G. F. Knowlton (August 18) : Codling moths have attacked most of the

apples at The Dell, in Skull Valley. Two sprays were applied. The insect is moderately abundant in northern Utah and doing considerable damage on a light crop of apples,

EASTERN TENT CATERPILLAR ( Malacosoma ame rica.ua Fab . )

Utah. Gr. F. Knowl ton (August l): Pear leaf blister mites have caused serious injury to a few apple trees at Smithfield. Apple trees at The Dell are heavily infested.

PEACH

ORIENTAL FRUIT MOTH ( Graphol i tha molesta Busck)

Massachusetts. A. I. Bourne (August 2§): Injury by the oriental fruit moth is very general in peach-growing sections.

Connecticut. P. (Jarman (August 23): In general the infestation is declining, but there are prospects of considerable damage in some orchards this year.

Delaware. D. MacCreary (August 23): The oriental fruit moth is moderately abundant on peaches. Fruit injury is somewhat greater in some areas than during the previous three years.

Maryland. H. S. McConnell (August 22) : The oriental fruit moth is very abundant.

Illinois. W. P. Flint (August 22): Oriental fruit moth adults have been taken in larger numbers than usual in bait traps.

South Carolina. W. C. Neetles (August 21): At Clemson College thare was less

damage than usual to Elberta peaches, but more damage than usual to varieties ripening later than Elberta.

Ohio. E. W. Mendenhall (August 24): The oriental fruit moth is very abundant this year all over the State, especially where treatment was not given.

Indiana. J. J. Davis (August 29): The oriental fruit worm has been very abundant. The earliest peaches were not heavily infested in many cases but the later peaches were almost universally infested and frequently very heavily infested. Where peaches adjoin or are interplanted with apple, the apple fruit will almost certainly show a high infestation.

Arkansas. D. Isely (August 23): The oriental fruit moth is unusually abundant

for this time of year in green peach shoots. Probably this is due to the late rains which have caused an excessive amount of green growth.

-233-

Georgia. W. K. Clarke (August 4): At Woolsey and Thomaston twigs have hardened and larvae are scarce in twigs. (August 11 ) : At Newman the larvae are scarce in twigs; at Madras a good many larvae are found in twigs, and succulent growth is plentiful and has not hardened in this orchard.

0. I. Snapp (August l): As usual,- the fruit infestation was extremely light this year at Fort Valley. Of 6,480 peaches cut open and examined, only 24, or 0.37 per cent, were, found to he infested. Of 12,217 Elherta peaches cut open and examined, only. 17, or 0.14 per cent, were found to he infested. A total of 18,63 7 peaches were cut open and examined in the Hiley aid Elherta orchards, aid the average percentage of them infested was only 0.22.

Tennessee. G. M. Bentley (August); 'The oriental fruit moth is scarce all over the State. Apparently this is the time between hroods. Early damage was heavy.

PEACH BOBER ( Aegeria exit iosa Say)

New York. P. J. Parrott (August 23): The peach borer is very abundant.

Georgia. 0. I. Snapp (August 21): Field mice and rats are again destroying many pupae at Fort Valley. We are finding hundreds of empty fresh cocoons near the base of peach trees which these predators dug out of the ground or tree and then ate out the contents. In all probability the infestation will be reduced again by the activity of these predators.

Tennessee. G. M. Bentley (August): The peach borer is very abundant in Knox County; plentiful in old orchards and scattered seedlings.

PLUM CURCULIO ( Conotrachelus nenuphar Hbst.)

South Carolina. Ir. 0., Nestles (August 21): 'The plum curculio is doing less damage to peaches this season than usual.

Georgia. 0. I. Snapp (August 21): 'The entire peach crop at Fort Valley was harvested with an infestation less than that of an average year. This was due to delayed emergence of first-generation adults from the soil in peach orchards as a result of dry weather in May and June. A few second-generation eggs were deposited as long as there were peaches in the orchards, but the majority of the new beetles will go into hibernation without having deposited any eggs this year. Therefore, oviposition in 1334 is expected to be heavier than it would have been had the first-generation adults deposited a part of their eggs in 1935.

Ohio. 2. W. Mendenhall (August 24): The plum curculio is very abundant on plum.

Wisconsin. C. L. Fluke (duly 25): The plum curculio is very abundant; there is a very heavy infestation in Richland County.

Arkansas. P. D. Sanders (August): Three curculio emergence cages, located in Howard, Pike, and Hempstead Counties in southern Arkansas, showed that the peak of first-brood adults emerged from the soil between June 12 and 20. Since the bulk of the commercial peach crop was not harve^tjed until late in' July, a second brood occurred. The extremely dry weathe^ prevailed while the insects were in the soil and a thorough-going control program were apparently responsible for the slight damage this year.

CHEEKY

CHERRY FRUIT FLY (Rhagole tis cingulata Loew)

Oregon. S. C. Jones (July 25): The cherry fruit fly "began emerging June 16; the peak was reached July 11. First maggots were found in Royal Ann cherries on July 6, at Macleay, in unsprayed plots. First full-grown maggots were found in a commercial orchard at Springfield on July 12 in Waterhouse cherries. First pupae were formed July 20 at Macleay. (August 25): The cherry fruit fly^was still emerging from ground August 24 at Rickreall. Cherries still on trees heavily infesded with maggots.

A SCALLOP SHELL MOTH (Calocalne undulata L.)

Massachusetts. A. I. Bourne (August 22): The last week in July there was dis- covered a considerable area in Plymouth County, particularly in the vicinity of Middleboro, where wild cherries were well-nigh defoliated by the cherry scallop shell moth. In many cases the trees had practically no green foliage left and were entirely covered by the peculiarly rolled a.nd webbed leaves.

In many cases these injured leaves had fallen and the trees were nearly as bare as during the dormant season.

SHOT-HOLS BORER ( Scolytus rugulosus Ratz.)

Indiana. J. J. Davis (August 29): Shot- hole borer was destructive to plum and cherry at West Baden and Cicero according to reports received the middle of the month.

AMTS (Formicidae)

Utah. G. F. Knowlton (August 24): Ants appear to have been responsible for killing a number of young cherry trees at Sandy, having made their nests around the bases of the trees. They are on the leaves in large numbers, attending the black cherry aphids which have severely curled most of the leaves on the trees still alive.

PLUM

PLUM GOUGER ( Ant ho nomas, scutellaris Lee . )

Minnesota. A. G. Ruggles (August 21): The plum gouger, heretofore only rarely seen, has been sent in a number of times from St. Paul, Mankato, and other southern points in the State.

GRAPE

Utah. G. E. Knowlton (August l): Leafhoppers E. comes ziczac Walsh are causing serious injury to Virginia creepers in all sections of Logan, and damage has been noted in many parts of northern Utah. (August 5): A species of Ervthrcneura is seriously damaging Virginia creeper and Fugleman’ s ivy at Biverheights, Hyrum, Logan, Millville, and Salt Lake City. Many of the leaves have already dried up and fallen, owing to the leafhopper attack. (August S): Crape leafhoppers are seriously damaging grapes at Boy. Most of the older leaves are badly spotted and yellowed. Some leaves are falling off. (August 15): Crape leafhopper damage continues to become more severe in many parts of northern Utah, particularly on Virginia creeper. In Logan from 10 to 75 per cent of the leaves of nearly all Virginia creepers are new brown and falling off. Damage to grapes is less severe, but increasing in several localities, including Brigham, Ogden, and Salt Lake City.

GRAPE LEAF FOLDER (Desmia funeral i s Ebn.)

vr

Missouri. L. Baseman ( Angus t 23): The grape leaf folder has done quite a little damage during the month at Columbia.

CRAPE BERRY MOTH (Polychrosis viteana Clem.)

Michigan. R. H. Pettit (August 23): There is a serious attack by the grape berry moth. Enormous numbers of eggs have been laid and sure now beginning to hatch. We are just beginning to pick Moore* s Early grapes; in fact, many growers in Berrien County began picking yesterday and are now looking forward to enormous numbers of the moth on the Concord and other later varieties.

PE MU

PECAN WEEVIL (Cure alio c ary ae Horn)

Georgia. T. L. Sissell (August 14): Adults of the pecan weevil were found in considerable numbers at Strouds Crossroads on July 22, 2 weeks earlier than in 1932. At Experiment, activity began about 1 week earlier than in 1932.

AIT APHID ( Monel lia costal is Fitch)

Georgia. T. L. Bissell (August 14): The black-margined aphid is more abundant on pecan for this time of year than in several years, at Milner and Strouds Crossroads.

sections recently, specimens collected in pecan orchards having been received from Jones, Perry, and Pike Counties.

CITRUS

CITRUS WHITEFLY ( Dial err odes citri Riley and How.)

Florida. J. R. Watson (August 24): The citrus whitefly is unusually abundant this year. Abnormally low rainfall for August in some sections has delayed the multiplication of the entomogenous fungi.

S. N. Berger and G. B. Morrill (August 23): This species and D. citrifolii Morg. are moderately to very abundant in various localities. Some citrus plantings are almost free of whiteflies, thanks to effective growths of fungi in such plantings daring 1932.

Mississippi. G. L. Bond (August 19): The citrus whitefly is very abundant around shrubbery at Lexington, Durant, and Greenwood.

H. Gladney (August 16): The citrus whitefly is very abundant on citrus at Ocean Springs.

LONG- TAILED MEALYBUG (Pseudo coccus adonidum L.)

California. H. J. Ryan (August 22): The long-tailed mealybug P. lonispinus, was found severely infesting a few citrus orchards near Whittier. Occasionally severe infestations in greenhouses and on ornamentals have been known in southern California for 15 years or more, but this mealybug has never before been found in great numbers on citrus. Associated in the Rivera section with Baker’s mealybug, P. marltimus Ehrh. , and the citrophilus mealybug, P. gahani Green, both of which are thoroughly under control this season by predators and parasites, the infestation by the long-tailed mealybug has so far been found only in some 10 or 12 groves where spraying, instead of fumigation, was applied last season for scale control.
