OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES EOR SEPTEMBER, 1931.

The grasshopper situation had not materially changed during the fore part of the month; during the latter part of the month, however, damage dropped off rapidly and egg, laying started.

The first specimens of the cotton leaf worm were observed in southern Mississippi on August 31. This is so late that there is little probability of any damage to fruit in the Northern States.

The common red spider continued to be troublesome throughout the month over practically the entire country,

A new and heavy infestation of the Japanese beetle was found at Springfield, Mass. This insect was also reported as having been taken at Charleston, S. C, at several localities in Somerset and Worcester Counties, Md., at Richmond, Va. , and as far west as Pittsburgh and Erie, Fa. It has also been found this summer at Little Falls, Wa thins Glen, Eort Edwards, Albany, and Buffalo, N. Y., and at Boston, Mass.

In this number of the Survey Bulletin is a report on the wheat survey which has just been completed in Illinois. The State average of tiller infestation for this year is 9 per cent as compared with 12 per cent in 1930. There is also in this number of the bulletin a detailed report of the wheat joint worm situation in Illinois.

A chinch bug outbreak in Charleston, S. C, caused very extensive damage to St. Augustine grass lawns in that city. Weather during September as a whole was favorable to chinch bug development in the East Central States and rather large numbers of these insects will in all probability go into hibernation this fall.

The green clover worm quite seriously infested soy beans, cowpeas, and clover in the vicinity of Chadbourn, N. C, and in south-central Tennessee.

The alfalfa weevil did more damage than ever before at Casper, Wyo. In some fields the foliage of the first cutting was practically destroyed.

The three-cornered alfalfa hopper did very appreciable dm age to alfalfa in fields along the Mississippi River in Bolivar and Washington Counties, Miss., and from Madison County to East Baton Rouge County, La.

The cowpea curculio was causing rather severe damage in po.rts of North Carolina and Alabama.

Apple leaf hoppers increased in numbers and destructiveness very decidedly during the month of September. Reports of damage were received from Rhode Island, southward through the Middle Atlantic States to Georgia and westward to Oklahoma.

The San Jose scale was reported as very abundant from Pennsylvania westward through the East Central States and southward to Mississippi. This insect seems to be on an upward trend in the East Central States.

The Oriental fruit moth, was but moderately abundant and did little â–  damage over' the New England, Middle Atlantic, South Atlantic, and East Central States, Very late varieties of peaches in northern Ohio were severely damaged, the. lemon freestone being about 50 per cent.

What has been tentatively identified as a European species of blister mite (Phyllocoptes f ockeni Na." & Tr.) was collected in southwestern Idaho, where it was russetting the leaves of plum. This insect has not heretofore been recorded from this country.

The grape loaf hopper developed rapidly during the early part of September and was reported from Iowa, Nebraska, Mississippi, and Utah as injuring grapes and woodbine, . . .

- Mole, crickets were occasioning considerable trouble in the truck regions/ and Alabama. In Nebraska these insects were pore troublesome than ever before recorded.

Blister beetles were quite generally destructive over the entire country from North Carolina" southwest wast to New Mexico. In the East Central and lest Central States they were particularly destructive.

The false chinch bug was reported as damaging cabbage, corn, turnips, and alfalfa in Nebraska, Mississippi, New Mexico, and Texas,

During the month the Mexican bean beetle increased in numbers in the drought area of 1930 to such an extent that it is "nearly as numerous in that ragion as it was in 1929.

An extremely heavy infestation of Puller's rose beetle was observed at Chadbourn, N, C, whero it was very seriously damaging beans.

The lima bean vine borer. was quite generally infesting lima beans at Chadb our n , N . C .

Harlequin bugs were reported as generally very numerous throughout the South Atlantic States as far north as Washington, D. C, and were also quite troublesome in the southern part of the East. Central States.

-501-

Both the pickle rud melon worms were doing excessive danr.ce to cucurbits in the Charleston area of South Carolina, The pickle worn was reported as damaging these crops in Alabama and Mississippi. These insects were also more prevalent than usual in Maryland*

The tobacco flea beetle was so numerous as to require the use of insecticides in the hurley tobacco districts of North Carolina and Tennessee.

The fall webworm was more troublesome in southern Hew England than it has been in the past 20 years. It was also reported as- generally abun- dant in the Middle Atlantic States southward to Delaware.

The spruce budworm has killed and is killing large areas of white fir in the vicinity of Halfway, near Whitman National Forest, Oregon, and in the Ochoco National Forest.

Eye gnats have been worse this fall than they have been for many years in the South Atlantic and Gulf States from South Carolina to Texas. Associated with, these outbreaks are numerous cases of conjunctivitis.

Various species of sand flies belonging to the genus Culicoides were quite prevalent from North Carolina to Florida and around the Gulf to Mississippi.

The stable fly was very unusually prevalent in the South Atlantic and Gulf region from Maryland to Florida, Alabama, and Mississippi. The condition was so serious in Wicomico County, Md., that many horses and cattle were forced into the surf and drowned.

During the past two months over 300 cases of damage to buildings by termites were reported to the Bureau of Entomology. The great majority of these cases were in the Southern States, but scattered reports were received as far north as Iowa, Ohio, and Pennsylvania.

OUTSTANDING ENTOMOLOGICAL FEATURES IN CANADA FOR SEPTEMBER, 1931

Reports of increasing grasshopper abundance and crop damage continue to be received from over a wide territory in the Dominion extending from Quebec to British Columbia. Species concerned are the lesser migratory and two-striped grasshoppers in the West, and the red-legged grasshopper in the East.

Infestations of the wheat stem sawfly, ranging from heayy to light, are reported from sections of south-central Alberta, southern Saskatchewan, and southern Manitoba, damage in wheat fields varying from 1 to 75 per cent crop loss.

Over much of southern Quebec, second-year white ':rubs have been causing extensive damage, particularly in unploughed sod areas, and considerable injury by these insects is anticipated in 1932. In eastern Ontario, the

.. ~5Q2~

majority of the grubs had transformed to the adult stage by early August. The species is Phyllophaga. an:da Lee. :. â–  .

In southern sections of the Prairie Provinces material damage to garden plants, flax, and, weeds has been done by the beet webworm. In certain areas the moth flights of this species, both in spring and late summer, have been the heaviest experienced for many years.

In sections of Alberta, damage and loss to the cabbage crop due to

diamond-back moth infestations have been .estimated at 25 per cent. In

south-western Ontario, the cabbage looper is reported as injurious to

cruciferous crops,

»

Insect pests are scarce in the orchards of the Okanogan Valley, British Columbia, with the exception of the red-humped and the yellow-necked c caterpillars, which are nore numerous in the Vernon district than for many years. '. •

A major flight of adults of the raspberry cane borer is expected in sections of southern Quebec in 1932, with resultant severe injury to raspberry canes due to the oviposition habits of the females.

In southern Saskatchewan and southern Alberta all types of shade trees have been heavily infested by the common red spider mite. The prevailing dry hot weather has been favorable to the increase of the mite and has lowered the vitality of the trees, with the result that the injury done is much greater than in normal years. ;

All forest stands containing large white spruce, in Cape Breton and Richmond Counties, Cope Breton Island, Nova Scotia, axe more or less in- fested with the eastern spruce beetle. The infestation of this species in white spruce also continues .over an area of 100 square miles on the north and south shores of the St. Lawrence. River in Quebec, east of Quebec City.

In the Muskoka district, Ontario, and in sections of southern Quebec, very conspicuous damage to the foliage of birch trees has been effected by the birch leaf skeletonizer,

Cottonwood blotch miners, Zeugophora sp., appear to have greatly increased during the past two years, in southern Saskatchewan and southern Alberta.. The black willow aphid is prevalent on Russian poplars in the central portion of the above two provinces.

An outbreak of the willow leaf beetle has resulted in the complete defoliation of native willows over a considerable area in Alberta, and Saskatchewan.

The European earwig, which has been established for some time on the Pacific Coast of British Columbia, in Vancouver, ITew Westminster, and neighbouring municipalities, is now believed to be present in all the settled areas on Vancouver .".Island. • ■ ■

W. A. Price (September 25): Grasshoppers are very abundant.

A. G. Ruggles and assistants (September): Grasshoppers were reported as moderately abundant from practically the entire State. They are still being reported as very abundant from Kittson, Wilkin, Morrison, Olmsted, and Freeborn Counties. (Abstract, J.A.H. )

J. A. Mur.ro (September 21): Grasshopper activity is over for the season but reports of injury have been received from five counties.

H. E. Jaques (August 27-); Grasshoppers are very abundant in nine central and western counties, and moderately abundant in other parts of the State, but apparently their attacks are growing less severe.

L. Baseman (September 28): Melanoplus femur- rub rum and â– â– â– . differentials â– gi'.e still abundant in Columbia, but not doing much damage to fall crops.

M. H. Swenk ('August 1 - 31): During the month of August there was but ver" little further development of the grasshopper outbreak in Nebraska. Scattering and very moderate additional infestations developed in Polk County, and local and very moderate infestations also developed in ITemaha and Pawnee Counties, but no important damage was done in any of these three counties. During the first week in August, near Peru in ITemaha County, the fungous disease of the grasshopper Ernpusa grylli worked very conspicuously among the differential grasshoppers (Melanoplus diff crentialis Thos.) living among the willows along the Missouri River, but the diseafe did not develop outside of the river bottom.

Kansas H. R. Bryson (September 23): ; Grasshoppers arc very abundant

"but not causing serious damage except in local areas.

Tennessee C. Benton (August): Grasshoppers are locally abundant throughout Lincoln and adjacent Counties.

Oklahoma C. P. Stiles (September 28): Grasshoppers are still quite numerous along the creek banks .and roadway's in the southern central counties. Under favorable conditions there mas'" be a serious outbreak in some parts of these counties, especially where there is considerable -waste or, grass land near fields . that will be planted to row crops next year.

A. G. Stephens (September 21): Grasshoppers are scarce in the northeastern part of Wyoming.

Nevada G. G. Schweis (September 25): A field inspection for

grasshopper damage on September 24 made in Douglas County showed considerable damage to alfalfa. Some hoppers observed depositing eggs on ditch barks and waste lands. Disease has made its appearance in the hoppers and large numbers were observed dead on the ground while many had crawled upon the stems of sweet clover and alfalfa and died. The county -agent made the statement that the hoppers had also been attacked and parasitized by a fly. Many hoppers were dissected in the field and this state y V was not confirmed but we have no reason to disbelieve it v. ^-i-' ••'•...

ARMYWORM (Cirphis ur.ipuncta Haw. )

C. Benton (August): Larvae of the second brood injured some millet fields near Mt. Hermon and JPayetteville. Several acres of corn, stalks up to 10 feet tall were seen largely stripped of leaves except midribs. Worms practically all pupated by August 30. Adults emerged August 31 from pupae collected the previous day.

COTTON LEO" WORM (Alabama argil lac e-a Hbn. )

C. P. Stiles (September 26): The cotton leaf worm is moder- ately abundant in the eastern two -thirds of Oklahoma. Hot dry

weather holding it in check. (September 23): This insect is present in practically all fields of rank cotton in the eastern two-thirds of Oklahoma. They reached the section too late this year to do very much.- -damage.

C. Lyle (September 22): Specimens or reports have been received at this office from 14 counties this season. The first specimen was collected at Lucedale, G-eorge County, on August 31. Reports and specimens received since that date. indicate a rather general distribution over all parts of the State. Most of the ii^esta'tions are apparently very. light.

W. J. Buckhorn (July 27 to August 1): There are comities s numbers of mourning cloak butterflies flying at present south of the Medford-Anna Springs Highway and west of- the Ft. Klamath Highway. They always fly into the wind and shift their course whenever the wind does. Large numbers alight on the Abies magnif ica. They seem to draw something from the lower part of the needles as they run their probosces around them.

COMMON n3D SPID.HR (Tetranvchus telarius L. )

Hew York P. M. Eastman (September 9): Specimens of injured twigs

of Boxwood, were received at this office today from Springfield Gardens and Bel?. port, Long Island. The injury is caused by- red spider mites although no cast sld.ns.were found to make a definite 'identification.

Mississippi C. Lyle (September 22): Complaints of injury to ornamentals

of various hinds have "been received recently from Bolton, Greenville, and lie1."/ Albany.

Utah G. I*. Knowlton (September 14): Rod spiders are damaging sugar

beets in a number of Cache Valley fields.

Washington M. A. Yothers (August): The common red spider has been and still is unusually abundant on apple, prune, cherry, locust, and many other kinds of plants in. the Wenatchee district. In a few orchards the mites have been eliminated by Stethorus pi c i pe s Casey, a small coccinellid beetle.

JAPA1TSSE BEETLE (Popillia japonica JTema. )

General C. H. Hadley and assistants, Japanese Beetle Laboratory

(August): Adults decreased rapidly shortly after the beginning of the month. There was a general desertion of most types of vegetation and a concentration on smartweed (Polygonum), which by the er±d. of the month continued to harbor fair numbers of beetles. Most first instar larvae transformed to the second instar during the month. This constituted the dominant stage in the soil during the last half of the month. The first third, instar larvae were found on August 19. Iggs decreased rapidly during the month and became relatively scarce after the middle. Scouting in the Pocono region of Pennsylvania gave negative results except for one beetle at Buckhill Palls, A new and quite heavy infestation was found at Springfield, Mass. Daring our surveys in this region grubs hive been found in large numbers. By the end of August, scouting operations were nearly completed, and, while much of the data have no"- vet been critically reviewed, it seems possible at this time to indicate with a fair approach to accuracy the limits of the area within which the Japanese beetle is essentially cent inn ovayBccurrer.ee. These limits are approximately indicated by the location of the fallowing nla.ee?: !-Tew Jersey: Mil ford, Plemington, Somerville, Perth Amboy, Red £ he, ani the coast from Asbury Park south to Ocean City, South Seaville, and west of Pen.visvill e, the shores of Delaware Bay; Pennsylvania: Kintersville, Buckville, Quakertown, Green Lane, Spring City, Coatosville, and Kennett Square; Delaware: Newark, and about midway between New Castle and Delaware City.

-508-

U. S. D. A. Press Service (September 18): The Secretary of Agriculture announced today that during the summer specimens of the Japanese "beetle have been taken at Charleston, S. C. The department reports the collection of beetles at various places outside the previously regulated areas, ".including several locations in Somerset and Worcester Counties, Md. , Richmond, Va. , several places in western .,.•.-■' -■■'.: $;<■&*'■ .-•■ , Pennsylvania, including Altoona and Erie, and scattered findings in New York State, including, Little Falls, Watkins Glen, Ft. Edward, and Albany. Specimens were also found again this year at Pittsburgh and IT ew Castle, Pa., Buffalo, IT. Y, , and Boston, Mass., where one or more beetles had been discovered in previous seasons, but where the department last year did not think it necessary to extend the quarantine.

Hew York C. P. Crosby (August 23): Specimen received from Elmira.

ASIATIC BEETLE (Anomala or i entails Waterh. )

Connecticut W. E. Brit ton (September 24): There is much injury this

season in the infested area where lawns have not been treated.

Hew York C. H. Hadley and assistants, Japanese Beetle Laboratory

(August): At the Jericho infestation, where the severe droughts of 1929 and 1930 reduced the abundance of the insect so that it was difficult to find grubs, they have multiplied again so that half an acre of turf injury/- by grubs has appeared on the lawn of the J. S. Stevens estate. The insect is definitely more abundant throughout the area than in 1930. No new infestations have been observed, but at the old infestations the abundance is rapidly increasing, except where the lawns have been treated."

ASIATIC GARDEN BEETLE (Aserica castanea Arrow )

New York C. H. Hadley and assistants, Japanese Beetle Laboratory (August): This species is definitely more abundant than during 1930 and more foliage injury has been observed. Heavy infestations occur on Long Island throughout the northern half of Nassau and Queens Counties, around the towns of Jericho, Glen. Cove, Locust Valley, Roslyn, Old Westbury, Port Washington, Groat Neck, Little Neck, Douglaston, and Flushing. The heavy infestations on the mainland occur in the northern part of Bronx County and the southern half of Westchester County.

WHEAT

HESSIAN ELY (Fhytophaga destructor Say)

E. N. Cory (September 25): The Hessian fly is scarce.

T. H. Parks (September 26): The Hessian fly is moderately abundant •

J. J. Davis (September 25): The Hessian fly is moderately abundant. Reported abundant in volunteer wheat in sections of southern Indiana.

W. P. Elint (August): The Hessian fly survey of Illinois made each year during the first part of August by the Natural History Survey and the Federal Bureau of Entomology, cooperating, shows the following conditions in the different wheat-growing areas of the State.

On the whole, there has been a slight decrease in the abundance of the fly in northern and east-central Illinois. In these sections of the State the fly is relatively scarce and it is not likely that any damage will occur. In the southern end of the State there is a moderate infestation, with conditions approxi- mately the same as last year, showing a slight decrease in all the wheat-growing sections. In east-central Illinois there has been a slight decrease with a very light infestation in this section.

In the west-central part of the State, in the section running from Randolph, Perry, Clinton and .Marion Counties on the south to Hancock, McDonough, Eulton and Peoria Counties, on the north, and on the east to Tazewell, Sangamon and Christian Counties, there is an area of moderately heavy to heavy infestation. Another area of heavy infestation is found on the east side of the State, centering in Crawford County,

Insects that feed on the Hessian fly are moderately abundant in most sections, parasitism being about 50 per cent in western and southern Illinois and somewhat less in the northern part of the State.

The recent rains have started the fly coming out and laying Qggs, and if these rains continue, wheat sown on the normal dates for highest yields should escape any serious infestation. If the present rainy period is followed by another period of drought, rains not occurring again until the latter part of September, the fly will come out a little later than usual and serious infesta- tion will occur for a week or ten days after the normal date of seeding for highest yi^ld.

CHINCH BUG (Blissus leucopterus Say)

..I., J.; Re id (September 23):;' St. Augustine grass lawns in Charleston are being .severely injured by an unusually heavy infestation of the chinch bug. The insect was present and did some damage to these lawns last summer and fall but seems to be much more, destructive this year. St. Augustine grass, locally known as "Charleston grass," is used quite extensively for lawn plantings in the Charleston area, being used more than any other grass. The phinch.bug infestation is general throughout the city and its environs, and entire lawns are known to have been destroyed. Drought is aggravating the insect injury,

T. H. Parks (September 25): During the corn harvest in north- western Ohio, chinch bugs were found quite plentiful throughout the fields, and in some fields their feeding apparently. hastened, the ripening of the crop. â– ' The season has been "Very favorable and the insects have increased greatly. ;

J. J. Davis (September 25): The chinch bug is scarce.

W. P. Elint (September 23): The weather, on the whole, has been fa,vorable to chinch bug development and a large percentage, of, bugs developing •■in the fields .have now reached the adult stage,

Louisiana W. E. Kinds (September 26) t The three-cornered alfalfa leaf hopper has caused a number of complaints of injury to alfalfa fields ranging from Tallulah to Baton Rouge along the â– Mississippi Valley. The injured fields turn yellow and close examination shows that the stems have been practically girdled by the feeding of the nymphs close to the ground. The gall formation following this feeding cuts off the flow of sap to the tops and the cortex tissues just above the gall break down and decay.

SUGARCANE BORER (Liatraea saccharalis Fat.)

Louisiana 17. E. Kinds (September 26); The sugarcane "borer is now increasing in abundance noticeably as' the third generation matures and the fourth generation, is starting. Infestation is most apparent in P.O.J. 213 cane. Egg collections made in many fields during September 1 to 15 showed no trace of Trichogramma in a number of localities.;. The o„verage percentage of natural parasitism by Trichogramma in uncolonized check areas during the period from July 11 to September 1 has ranged from 6.6 to 22.6 per cent. In the average of all colonized areae during this period parasitism has ranged from 57.9 to 71.6. While in the average of fields adjacent to colonized areas the percentage has ranged from 35,6 to 68.9. It is expected that the peak of parasitism- 'will be reached in cone fields before the middle of October on 4th generation borer eggs.

The codling moth is very abundant in western New York.

Pennsylvania H. IT. Worthley (September 16): The codling moth is very- abundant in many orchards of Franklin and Adams Counties.

Delaware L. A. Stearns (September 26): The late secor.d and third

brood larvae of .the codling rroth are doing but moderate injury.

Virginia T7. J. Schoene (September 23): The life history studies

of the codling troth in the Blacksburg and Roanoke section indicate that there will be no third brood this year. The commercial fruit growers are nicking apples. They report many stings but few apples with worms. It seems that the insect has been held ir. check in commercial orchards in the central part of the St te in spite of the heavy carry-over from last season.

Georgia C. H. Alden (September 21 ): The codling rroth is very

abundant in Cornelia. :Tc fresh injury noted, e^g laying is over, many worms are going under the bands, and few are pu- pating. Most of the larvae are making winter cases.

Ohio T. H. Parks (September 26): The codling moth is moderately

abundant generally and very abundant in Ottawa and Lawrence Counties. Lawrence is the only county in which there has not been a good degree of control generally. The infestation on the hill orchards of that county averages from 10 to 40 per cent, most the blemishes being stings that do not ruin the fruit for sale. Three commercial orchards in northern Ohio have suffered from, this nest this year, even though a good snraying urogram was followed. Nearly all of the orchards in the State outside of Lawrence County have had good control with sprays. We have hs.d a partial third brood of larvae in Lawrence County, though not so many as aopeared in 1930.

Washington M. A. Yothers (September 21'): The codling moth is more

abundant and injurious this season than -it has been for sev- eral years.

Washington S. J. Newcomer (September 21): The codling moth is un- doubtedly more abundant this season than it has ever be.en. This was brought about oy a combination of a mild winter, an early spring, and unusually favorable weather for ovi- position during May and' June. Moths from overwintering larvae emerged early and deposited many eggs, resulting in a very heavy second brood and a partial third brood. Almost continuous cool, cloudy weather since September 5 has prac- tically put a ston to codling moth activity for the season. A total of 11,630 moths have been caught in 5 baits during the sea-son, as compared with 4,016 moths caught in the same number of baits located in- the same trees in 1930. The orchard Was given practically the same treatment both 3.rea.rs, being sprayed seven times during the season.

hoppers attacking apples have been present in srrall nuirbers throughout the summer,, the nuirbers increasing as the sumrcr advances. In a few orchards in Shenandoah and Roanoke Coun- ties the insects are so numerous that the fruit is being spotted and the foliage injured by the feeding of the adults. Fully 90 per cent of the damage is being caused bv Typhi ocyba pomaria McAtee. These are present more or less in the adult stages There were just a few lr/rrphs on the foliage Septerrber 15. The weather has been dry and very hot during the month of Septerrber, and it is believed that the high temperatures have been favorable to the insects.

SPRUC5

A WEEVIL (Pissodes sp.)

Washington W. W. Baker (September 22): Mr. Thaanum, horticultural in-

spector for Skagit County, reports considerable damage in one planting of Colorado blue spruce at Burlington. One native spruce at Sedro-Wooley was also reported infested.

WALNUT CATERPILLAR (Pat ana integerrima G. & R. )

Virginia C. R. Willey (September 28): The walnut datana is very abund- ant in Richmond section, occurring on black walnut, English wal- nut, pecans and hickory. It created considerable interest due to its habit of clustering on trunks for molting.

Georgia J. 3. Gill (September 26): There has been a very light in-

festation of the walnut caterpillar in pecan orchards of this section (Albany).

Tennessee J. U. Gilmore and J. Milam (Seiotember 24): Numerous instances of complete defoliation on black walnut were noted at Clark— ville.

Nebraska M. H. Swenk (August 1-31 ): The walnut caterpillar stripped

many walnut trees of their leaves in southeastern Nebraska dur- ing August, and was the cause of many inquiries and complaints.

Kansas H. R. Bryson (September 23): Dr. E. G. Kelly reports that

practically every walnut tree between Manhattan and Lawrence has been defoliated. Observations in the vicinity of Manhattan indicate -ithis condition to be true here also. Dr. Kelly also reports Datanas attacking apple and oak rather generally over the State. Oak, apple, and sumac have been defoliated at Man- hattan.

EYE GNATS (Hippelates sp. )

South Carolina J. N. Tenhet (September 23): Eye gnats are worse thaii for many years. Sore eyes or conjunctivitis is almost epidemic among children in this community. It is very unusual for eye gnats to be so abundant and troublesome this late in the fall. Possibly the severe drought and continued heat are responsible.

Florida W. E. Dove (September 17-20): Eye gnats (H. pusio Mall.)

were numerous at Marianna, live Oak, Lake City, Pensacola, Panama City, and at points between these localities. They were present about the eyes of persons and the eyes of cattle.

ANTS (Formicidae)

M. R. Smith (September 13): Mr. J. A. Berly recently sent me for determination a form of fire ant, Solenopsis geminata Fab,, subsp. rufa Jerdon, which was collected at Summervxlle on September 7.

M. R. Smith (September 18): Mr. H. H. Wedgcworth, Associate Plant Pathologist at the Everglade Experiment Station, Belle Glade, has sent me two species of ants which lie states are infesting houses there. One of these has been determined as Pharaoh's ar.t, Monomorium pharao:eis L. , and the other as M« floricola Jerdon.

M. H. Swenk (August 1-31): Daring August, as also earlier in the season, ante were the cause of much annoyance to housekeepers. An unusually large number of these complaints, for this region, related to the small red ant (M. pharaonis).

M. R. Smith (September 19): Argentine ants (irldomyrnex humilis Mayr) wore recently discovered at Northport.

M. R. Smith (September lc): A correspondent living in the country near Quitman complains of anunusual abundance of lion an t s , Do r-; m iyme r. pyrr;lcua Roger, on the front porch of her house and in the yard. Mr. 0. H. Chance reports Argentine ants from Yokona. The infested area is a rural one lying 2 niies southwest of the Glass station on the Y. & M. V. railroad. Mr. R. P. Coiner recently found acrobatic ants infesting a kitchen at Moss Point, where preserves were being prepared. I have tentatively determined the ants as Crcmastogaster ashmeadi Mayr.

-568-

State Plant Board (September 19): It is "believed that the Argentine ant is now completelj' eradicated fron Columbus over the largest' area in the world in which this pest lias been exterminated. A thorough scouting of the previously infested areas, block by block, this summer failed to reveal but two colonies of the ants, which were promptly destroyed by oil and fire.

About 76 city blocks were badly infested with the ants at one time. About 40 other places in Mississippi have eradicated the Argentine ant in cooperation with the State Plant Board, but the area cleared in Columbus is the largest.

C. Lyle and assistants (September): The Argentine ant situation in this vicinity is very encouraging at the present time, no Argentine ants having been found thus far at four of the previous infestations, namely, Grenada, Puckhill, Beattjr, and Kilmichael. They have also been reduced to a very small area in the city of Water Valley, and only a few have been noticed in the cities of Winona, and Tillatoba. The Argentine ant is very annoying to residents in places where no control campaign was conducted last j^ear. In Brookhaven, where a campaign was conducted in March, 1929, these ants are numerous in only a few residences at this time. The size of the Argentine ant infestation is greatly increased at Rodney, owing to overflows of the river in 1927 and 1929. Fire ants (Solenopsis geminata Fab.) completely destroyed plantings of fall turnip greens in many gardens 'in 'G-eorge and Ferry Counties. Ants completely destroyed a 5 acre field of beets sown late in August at Lucedale. Florida harvesting ants (Pogcnomyrmex be.dius Latr. j dot. M. R. Smith) dug up the seeds, taking them to their nests; and Eon ants (D. pyramicus Roger, det. M. R. Smith) chewed off most of the plants that came up, leaving a bare field.

Texas S. W. Clark (August 27): There was more damage than usual

this summer at Weslaco by Solenopsis geminata Fab. attacking citrus. The indicata.ions are that the infestations will be particularly severe during the fall months.

FLANT QUARANTINE AND CONTROL ADMINISTRATION

Notes abstracted from "News Letter" for August, 1931. (No. 9, Issued September 1, 1931.)

Not for publication

GIPSY MOTH (Porthetria dispar L.)

There was less defoliation caused by the gipsy moth this summer than for several years, and the trees in most of the area were practi- cally free from gipsy moth feeding. Defoliation was severe in the counties of Bristol, Plymouth, and Barnstable, Mass. There was recorded a total of 204,720 acres in New England which showed some feeding by the gipsy moth caterpillars, but over one-half of this was classified as less than 10 per cent defoliated, leaving 101,583 acres classified as from 10 to 100 per cent defoliated, and over one-half of this amount (54,710 acres) was in the southeastern section of Massachusetts. Practically all of the defoliation records are now available; there may be a few scattered ones received later, so that these figures may have to be changed somewhat, but it is not expected that any material change in them will be necessary.

In the part of the Barrier Zone in New York State which is cared for by the New York Conservation Department, scouting was carried on during July in the townships of Ancram, Austerlitz, Canaan, and Hillsdale, and apparently no infestations were discovered during the month. On Long Island the New York Conservation Department had 5 crews doing inten- sive scouting in North Hempstead Township. No indications of gipsy moth infestation were found as a result of this work.

JAPANESE BEETLE (Popillia japonica Newm.)

Plight of the adult Japanese beetle in the market and waterfront districts of Philadelphia reached such proportions that, beginning July 10, it was necessary to curtail the period during which farm products could be inspected and certified for movement from the generally infested area. Plight of the Japanese beetles in the heavily infested areas of New Jersey and Pennsylvania was studied during June by plant pest control officials from several other States. In a number of the localities visited, damage to crops was found to be greater than in preceding seasons. The beetle flight was still in progress at the end of August.

SMALLER BAMBOO SHOT-HOLE BORER (Dinoderus minutus Fab.)

A shipment of approximately 28 tons cf G-ynerium saggittatum, G> saftpharoidcs, and Arundo donax, imported at Philadelphia on July 28 for the purpose of testing machinery, was found to be very heavily infested, esT^ecially the Gynerium, with this bamboo borer.

SATIN MOTH (Stilpnotia -shlicis L.)

The 'satin moth has "been found -out side of the quarantine line in 8 towns in Connecticut; 2 towns' lh'Massachusetts, one of which. (Williamstown) "borders the Vermont' arid "New York State lines; 1 town .-'. in Vermont, and. 9 towns in Maine. Ho infestation "beyond the quarantine line in New Hampshire was- found. as. a result of this work. This work is not entirely- completed so that recommend-ations for changing the present quarantine line Can not be made, at this time.

â–  ' EUROPEAN CORN BORER (Pyrausta nubilr.lis Hbn.)

Increase in* infestation of the corn borer over most of the territory is indicated by a summary of the field reports on the egg survey in the western area, which was completed on July 22. This under talcing, commenced on June 25, was conducted by the Administration in cooperation with the Bureau of Entomology. Sections of Hew York, Ohio, and Michigan were covered by the 22 :r.en employed, 20 of whom mr.de .the counts with 2 acting as supervisors.

LESSER 3ULB' FLY (humerus strigatus Fallen)

An "active general field infestation" of the lesser bulb flies in Tennessee, where the capture of one specimen earlier in the season was reported in the July issue, is disclosed through field observations by G. W. R. Davidson. Several adult flies were observed in most of the plantings, and in the Victoria variety they were quite numerous. In one Georgia planting a number of larvae of the lesser "bulb fly, some appar- ently full grown and others about half grown, were found in one veriety of bulbs immediately after digging.

PIKE BOLLWORM (Pectinoohora gossyniella Saund.)

During the month of July, field inspection in the Salt River Valley of Arizona consisted of making infestation counts from 23 selected fields, 20 of which are in Maricopa County and 3 in Pinal County. The results have all been negative. This is somewhat surprising when it is recalled that 2 of the fields selected in Pinal County and 9 in Maricopa County were infested last season. Also 2 of the fields in Maricopa County were found to be infested this season prior to the beginning of the infestation counts. This would seem to indicate that the infestation is still very light. • One of the most logical conclusions for not finding specimens, especially in the 2 fields where they were found earlier in the season, is that the bolls are now developing much more rabidly than the infestation.

An infestation count Consists of the inspection of 100 bolls. Estimates were made recently to determine the number of bolls per acre, which was found to be 919,080. In examining 100 bolls from this number, it can be readily seen that the chances of finding specimens are very slight, except where the infestation is heavy.

Field inspections have also been made in the Tucson area. By using 10 squares or green bolls per acre, 1,225 acres have already been inspected

-572-

witli negative results. Practically .all of the cotton acreage in the district will "be covered "by this method of inspection in another month.

One of the new gin trash machines mounted on a truck was sent to the Lower Rio Grande Valley of Texas on July 24. Other machines were sent out as they were completed, so that by the end of July there were five machines operating in the above area. These machines inspected 2652 "bushels of trash from 25 gins with negative results.

MEXICAN FRUIT FLY (Anastrepha ludens Loew)

As a supplement to the inspection work this summer, 1,077 fly traps similar to those/in Florida were placed in 118 selected groves during the first part of July. The use of these traps resulted in the taking of one adult Anastrepha (not ludens) , July 14, in a grove one mile south of Mission, Tex. Additional traps placed in this and the surrounding groves gave negative results the remainder of the month.

Adult flies continue to be taken in the traps in Matamoros. During the month 176 traps were maintained in 57 different premises scattered throughout the city. The use of these traps resulted in the taking of 30 adult flies on 13 different premises. Of interest in this connection is the fact that in only 4 of these premises were reinf'e stations found. All trees within an area of four blocks around each point of infestation were sprayed at weekly intervals with poison-bait spray.

OUTSTANDING ENTOMOLOGICAL FEATURES IN MEXICO, SUMMER OP 1931. Alfonso Dampf , Head of Department of Research Officina Federal para la Defensa Agricola, San Jacinto, D. F. (Mexico)

The extraordinarily heavy rains which fell in June and July in Mexico had very interesting effects on insect pests. There v/as an un- precedented outbreak of cutworms, not only in the central highland but also in the tropical parts. Reports were received from the States of San Luis Potosi, Michoacan, Hidalgo, Mexico, Puebla, Guanajuato, Morelos, Veracruz, Guerrero, Oaxaca and Chiapas. The species most destructive to alfalfa proved to be Copitarsia con sue ta Wlk.,a noctuid known as a potato pest, a borer of cabbage heads, and an enemy of tobacco plants. (Dampf det.)

Another surprise was the appearance of the chinch bug, Blissus leucopterus Say, in the Ixtlahuaca Valley, State of Mexico, 400 meters a"bove sea level, as a serious pest of corn, the first case since the establishment of an organized plant protection service in Mexico. Corn planted in June was without exception badly attacked; fields planted in April looked healthy. The pest eerie from the winter-wheat fields and is apparently at home in the tussocks of alpine grass in the nearby hills and mountains. E. G. Barber, U. S. Bureau of Entomology, identified

-573-

the specimens as unmistakably chinch hugs, hut much darker than the United States variety.

A false chinch hue (apparently, llysius sp.)-, influenced hy the sane meteorological conditions as Blinsus leucopterous Say, appeared in alarming number in the cornfields in the State of Hidalgo.

In the State National Park Desierto de Los Leones, Federal District near Mexico City, Lachnus sp. was extremely ahundant during May, attacking young trees of Abies religiosa. The stems were in some cases covered with a crust of aphids for a span of two meters.

Halisidota caryae Harr. defoliated many rose hushes in and around Mexico City during August. In some cases corn was attacked and small plantations in gardens were entirely destroyed.

During a visit to the West Coast of Mexico, in the month of June, the joint commission composed of Mr. Trotman and Mr. Townsend from the Plant Quarantine and Control Administration, U. S. Department of Agriculture, Washington, and Mr. I. Hernandez Olmedo from the Oficina Federal para la Defense. Agricola, Mexico Secretaria de Agricultura, located the following infestations of fruits hy larvae of the genus Anastrepha:

In guayaba (Psic'ium) in Mazatlan, State of Sinaloa,

prohahly Anastrepha striata Schin. In Mexican plums (Spondias), in Mazatlan, Sinaloa,

prohahly A. fratercula 'Tied. In sour oranges, Tepic, Nayarit, prohahly A. ludens Loew. • In Caimito (Chrysophyllum cainito) , 21 Dorado, Sinaloa;

one adult obtained proved to he A. serpentina VJied.

This extends the known infested zone considerably to the northwest.

On their return trip, the U. S. commission was accompanied by Mr. E, Coppel Rivas and additional investigations were made, with the result that fruit fly larvae prohahly A. striata were also found in Culiacan, Sinaloa, in guayabas.

INSSCT CONDITIONS IN PORTO RICO DURING AUGUST,. 1931

M'. D. Leonard Insular Experiment Station, Rio Piedras, Porto Hico

The yellow cane aphid, Sipha .f lava Forbes, was observed- doing con- siderable damage in a number of large sugarcane plantings of young to fairly large erne near both Aguirre end Santa Isabel on August 22. Mr. Foss, Assistant Field Manager of the Aguirre Sugar Co., stated on that date that during all of July and August there had been a rather .general, though fairly light, infestation throughout nearly all of the company's extensive plantings, in spite of the fact that the rainfall had been greatly in excess of normal.

A leafhpp-oer, Protaleora brasiliensis De Long, known to be a minor pest of sugar cane , continued to be common in all stages throughout t. month on many patches of Bid-ens pilosa at El Morro in San Juan.

.ie

Adults of the scarabeicl beetle Dy seine tus bjarbatus Fab., an occa- sional minor enemy of sugarcane, were observed in small numbers at lights at Hato Hey on August 31. (M.D.L. ) At Isabel a adults were not observed at lights throughout the month and hod not been seen at lights since June B. (G.N. Wolcott. )

Scattering male adults of Phyl 1 onhaga vandinei Smyth were collected on sugarcane on August 11 and 12 at Isabela bu.t even by the end of the month they were not common there. (G. IT. W. )

The attacks of the cotton leaf worm, Alabama argil lace a Hbn. , naturally abated throughout the North Coast during the month, due largely to the fact that most of the cotton plants were old and no longer succu- lent. . According to F. E. Rorko of the San Juan Ginnery Co. at least 80 to 85 per cent of the crop ha.d been picked by the end of the month. Around Manati, however, the insect was active until at least the middle of August and apparently in several other localities there was a certain amount of feeding.

The pink boll worm, pectinouhora gossyoiclla Se.und. , was generally infesting the whole North Co art cotton growing section during the month, according to F. 3. Rorke, the infestation being worst, however, in the vicinity of Arecibo, Hatillo, in parts of Camuy, and in Aguadilla. The infestation in a number of fields in these places ran as high as 100 per cent. At Maleza, near Aguadilla., a fair sized patch ras examined on August 4th which showed 100 per cent of the bolls infested after only one picking; a single boll picked at random showed 7 exit holes. At Isabela the infestation was somewhat lighter. It is estimated that there has been about 50 per cent loss of the crop this seas.on in the entire North Coast region, due to excessive rainfall, the pink boll worm and the cotton leaf worm. It is difficult to say how much of this is directly chargeable to

-575-

the -rink boll ?orrr, but orobably rt lr?t half the loss should be attributed to it. As - whole the loss has rot beer- so great on the North Cor>st as or. the South Coast, but ir. certain northern localities it was as bad as in the worst infestations on the South Coast.

A cotton stainer, Dysdorcus rr.dreac L. , ras not abundant during the month and apparently did no appreciable drrr.age. (F.3.R. )

Tic melon worm, Dia-ih^nia hya.llr.ata L. , was generally present and troublesome to cucumbers at the station at Rio Piedras during the month necessitating 'spraying almost every other dnv to keep the oest in check.

The melon aphid, An" vis yossyoii Glov. , was troublesome to cucumbers at the st'tation at Rio ?iedra,s throughout the month but Fas satisfactorily held in'chcch by froouent spraying. This insect was generally present but net serious or p. patch of okra at the station at Rio Piedras during the month.

A lima bean pod borer, ??aruca, tcstulalis Geyer, was observed doing considerable damage to the patch of pole limas at the Rio Piedras Station on August 18 by the larva.e eating into the blossom buds, which were then abundant, and feeding on the ovaries (P. Sein). Search ~t the end of the month, however, showed very few blossoms oresent and only one dead half-grown larva. (M.D.L. ) linety pods examined at the Isabela Substation showed no infestation, (G.iT.T. )

Tie lima. bear, ood borer Ptioll^ zir.cher.rlle Treit. -as not present in 90 lima bear, pods examined at the substation at Isabela. (G.I'.T. )

The bean leaf roller, Gor.iurus ^roteus L. , was moderately abundant on pole limas at the station at Rio Piedras, P. R.

Tie bean leaf webber, Nacoleia indicata Jab., was fairly abundant on pole limas during the month at the Station at Rio Piedras but possibly not cruite so abunda.nt as during July.

A leaf beetle, Diabrotica gramir.ea Baly, caused considerable damage to limp beans ?t the station, especially to the blossoms, but also some leaves. (Phis beetle and Maruca and the lacebug combined prevented nod formation entirely, although other factors wore undoubtedly responsible for the nonformrtion of pods, possibly too hot weather.

A bean leaf hopper, Prooarca f.-Vlis Do Long, w-s fairly abunda.nt on lima beans at the Itation at Rio Pi idras during the month.

A leaf bug, probably Eval lodes a. sp. , according to Dr. H. H. Knight, was observed generally distributed at the end of the month in moderate numbers on the underside of the leaves of the pole lima beans er.d the okra, which grow on adjoining patches; both are about 25 or 30 yards away from the Ar.or.c. diversifolia trees upon which the insect feeds; no nymphs covld be four.d on either the beans or okra.

-576-

The cottor. lacebug, Corythucha goj^rjeil Fab. , Fas very destructive at the Rio piedras Station on pole lima..s, ir. creasing in a bur.dar.c'e so that by the end of the month many le'aves Fere broFninh and dry, the insect s being present in all stages in great numbers.

Hie Scarabee, guscgoes batatag Uaterh. , -as found lightly infesting one sweetpotato tuber in the public market at Puerta de Tierra, San Juan, (H. Faxon and E.G. Oakley-.)

A small blackish flea beetle Fas very common in all the sFeetnotato patches examined and apparently doing scire damage. This looks like ChaetocneTa a.nricaria Suf friar:, and I fouIcI say definitely it is that species, for it is our sFcetootato flea beetle in Porto Rico, except that Long and Mutchlor do not record it from Antigua — only from Porto Rico and Cube,, and in the Supplement they add Jamaica and Haiti.

An adult of the bug Snartocera batatas Fab. Fas found attacking sFeetpotatoes in the oatio of the Tain building at the station at Rio Piedras on August 18 and later in the month several adults Fere observed on the walk outside the same building.

A leaf miner, Arrorryza. ip_ojreae Frost, Fas "ore sent throughout the

month as usual in ^oder^tc numbers in several sFeetnotato matches observed.

The cotton lacebug, Corythucha gossyoii Fab., Fas found tOFards the end of the rronth in snail nuTbers on the okra, at the Rio Piedras Station. The okra adjoins the "oole lirras on which the insects Fere breeding very abundantly. Only adults could be found on the okra., but these Fere feed- ing to a. noticeable extent, causing the characteristic yelloFish stipnled areas on the leaves.

A leaf beetle, Diabrotica gramir.ea Paly, did considerable damage to leaves and blossoms on the okra. natch at the Rio Piedras Station.

A whitefly, undoubtedly Al eurotrachelus trachoides Back, was found on August 17 to be badly infesting a house pep-oer plant in Santurce.

The red- banded thrips, Heliothrios rubrocinctus Giard, was observed doing considerable to moderate damage to the foliage of about 1,000 nursery mango trees at the station at Rio Piedras. Thorough soraying o.t once almost eliminated the insects, but by the end of the month they were again beginning to get a good foothold.

The papaya, fruit fly, Toxo try nana curvi cauda Gerst., Fas found to be infesting the fruits of a number of nanara plants on a. farm near Ponce on August 5. One fruit, small and green and about 2-1/3 inches long, con- tained 20 larvae, and another, somewhat more mature and about 5 or 6 inches long, contained 24 larvae; in both fruits the maggots were nearly to* fully grovn. The owner stated that during May and June nearly all of the fruits on his trees was infested, many so badly that they had to be thrown away.

The white peach scale, Aulacasois nenta?ona Targ. , was moderately abundant on napaya trees or. a farm near Ponce on August 5. Several "pesquin" trees (Albizzie, mollis) at the Hio Piedras Station, used as shade trees in an experimental coffee planting were rroderately infested with this scale.

Adults of Diaureucs sTJengleri L. were present in fair numbers (but fewer than on the same trees last June) on several trees of a Picus (probably P. laevigata) near Santa, Isabel on August 20-22. Thirty-five egg rra.sscs were collected during several hours of careful search in an effort to obtain tfrichogrammid Cr-^> parasites for introduction into Barbados. The percentage of parasitisir corld not be determined at the tire.

A leaf tyer, Dichoreris pineratus Wlsm. , was found to be rather badly infesting a small experimental catch of alfalfa at Malcza in the munici- pality of Aguadilla on August 4. This is in a rather isolated section containing many hat palms, and little farming has been done there; this occurrence of the insect in injurious number's at sore considerable distance from the only other nearest alfalfa grown at the Isabela Substation again raises the cuestion as to what the natural leguminous food, plant of the insect really is.

An undetermined scale was brought in en August 8 by Dr. T. Breggcr, ^ho stated that several "bucare enano" trees (Srythrina berteroana) were somewhat infested in the experimental coffee plots at the station. On the same date Dr. Bri gger found an voi determined scale which was rather badly infesting several "ucsou.in" trees (Albizzia roll is ) used as shade trees in an experimental coffee planting at the Pio piedras Station.

The Hawaiian beet webworm, Hymenia fascial is Cram., wr.s much less abundant than during July at El Morro in S^-n Juan. The scarcity of the moths and larvae was undoubtedly duo to the destruction of most of the patches of the weed "arraza contodo" (Gonuhrona d.isucrsa) on which the insect has been feeding there.

Mealy bugs, Pseudc coccus spp. , rcre observed and are generally distributed on sugarcane, but are of minor import ance.

The sugarcane looper, Remigia (Mocis) rep an da Fab., has been abun- dant and generally distributed during the year, feeding both on sugarcane and several grasses, especially Panicurr maximum. (Harold 3. Box. ) A '*. caterpillar was observed on August 28 feeding on guinea grass on the summit of Boggy Peak, the highest point on the island, 1350 feet.

Man;'- coconut trees were observed the leaves of which had turned yellowish or brownish. Upon closer observation these rero found to be badly infested with Agpidiotus destructor Sign.

The mango thrips, Heliothrips rubrocinctus Giard, was very scarce to absent on a number of mango trees examined in several oarts. of the ^r-'l^sd* This scarcity may be due to excessive rainf â–  11 during and previous to my visit.

The banana root weevil, Cosmopolites sordidus Germ. , was apparently not present in banana, piants observed in several localities. I believe it has not yet been recorded from Antigua.

Hed spiders, Tetranychus sp., we're almost entirely absent on several

Grasshoppers ( Locust idae) were doing some damage to the leaves of cassava.

The pink boll worm, Pectinoohora gossypiella Saund. , badly damaged the 1928 cotton crops. The hurricane in the fall, however, destroyed all the young plants which were growing, and the crop of 1930 was free from the pest. This past season's crop, however, wa.s lightly Infested towards the end. The crop following the 1928 hurricane in Mont s err at, it is',. interesting to note, was apparently damaged, according to Mr. Warncford, as badly by pink boll worm as those crops preceding it.

The cotton leaf worm, Alabama argiilacea Hbn. , wa.s scarce on cotton during the past year.

A cotton stainer, pysdercus andreao L. , was generally present on cotton but only of minor importance.

The cotton blister mite, jJriophyos ~oss,ypii Glov. , was scarce as usual and did little damage.

A leaf beetle, Honopha.eta. aecminoctialis Fab., was swept from s^eet- potatoes in small numbers and also observed in other plants, but the extent of the feeding of the adults, if any, was not determined.
