Even though a high degree of control was obtained for screwworms 
in the Southwestern States, the spread of the pest resulted in cases in 
six counties of Oklahona, several localities in Kansas, and in Missouri, 
Illinois, and Tennessee during the early part of the season. In the 
stockyards nen employed "by owners to handle cattle looked for cases of 
screwworms, treated the animals, and aided in getting specimens for 
identification. At Kansas City, Mo., there were 10 such infestations; 
at last St. Louis, 111., 39; at Kaplan and Church Point, La., 3 in 
horses and mules; at New Orleans 10 lots were identified from 59 dif- 
ferent infestations', and at Nashville, Tenn. , 1 case was found. Screw- 
worms "became established in the vicinity of Memphis, Tenn., and caused 
losses in several of the southwestern counties of the State. (W. E. Dove,

MOSQUITOES 
Information received from the State entomologist of Hew York 
and the Nassau County Extermination Commission indicates that an 
unusually dry summer on most of Long Island and throughout much of 
the State resulted in fewer mosquitoes than normal early in the sum- 
mer and in midsummer hut later rains and storms brourht out heavy 
local "broods late in the summer and early in the fall. The storms 
and floods provided extensive bre ding places lor the fresh-water 
species, Aedes vexs.ns Meig, , Culex pipiens . L. , and the salt-water 
breeders, A. sollicitans (Walk.) and A. cant at or (Cnq,). A large 
brood of Mans on ia per turbans Walk, emerged in Suffolk County N.Y. 
in Juno. Along the mid-Atlantic seaboard September storms caused a 
slight increase in abundance of salt-marsh mosquitoes, but during 
the rest of the year the numbers were approximately normal. In New 
Jersey a heavy emergence of A. vexans occurred in the upper Passaic 
Valley as a result of extensive flood waters. Emergence began about 
June 26. Immediately after that date some mosquitoes were observed 
along the lower Passaic, but none were present when a status was 
taken along the west side of the two mountain ranges toward the upper 
end of the breeding area. This was about h miles from the principal 
breeding area. By July U, mosquitoes that probably bred on the upper 
Passaic, had come across the mountains and filtered into all the towns 
and cities to the east and south to a distance of some 15 miles from 
the large breeding area on the upper Passaic Hiv.-r. 
In Delaware, conditions for mosquito breeding were more favor- 
able in 1936 than in 1935. with an apparent general slight increase 
in the number of pestiferous species. However, over a 5-year period 
there has been a steady reduction in abundance, particularly of the 
salt-mash species, as indicated by trapping records. 
An unusually dry spring and summer was perhaps responsible 
for a greatly decreased abundance of salt-marsh mosquitoes along the 
Georgia coast. Annoyance from these pests in that area was reported 
at its lowest ebb for several years. The dry weather also probably 
accounted for fewer complaints this year from fresh-water and domestic 
species.
