Gadsden Counties, of western Florida, and in Madison, Taylor , Hamilton, and 
Nassau Counties, of northern Florida. During September and October a high 
incidence occurred in the vicinity of Starke, Dalatka, and St. Augustine, Fla., 
and along the west coast another endemic area extended from Dunnellon south- 
ward to Punta Gorda. County agricultural a,gents were of the opinion that most 
of the cases in the two principal foci developed in hogs which roamed the wo off 
and that bites caused by the Gulf coast tick were the principal predisposing 
causes. (¥. D. Dove, Bureau of Entomology and Plant Quarantine, U. S. D. A.) 
I believe the screwworns were worse in 1940 than they have been since 
1935 , the year in which they were so severe. The infestation was general over 
most of the State but not so severs as it was in some of the Southern Stokes, 
In the weekly county agents’ reports on conditions on livestock, they did not 
report any loss because of screwworns. (C. F. Stiles, extension entomologist, 
Stillwater, Okla.) 
Weather -conditions have been very mild in Arizona for 3 years; conso- 
quently < there has been little or no destruction of these flics. Last year 
screwworns infested susceptible wounds during each month. Probably our worst 
season was during October, November, and December, This year they ho.vc been 
bad during the summer and fall. Many stock men report that this has been the 
worst year of their experience, (¥. J. Pistor, University of Arizona.) 
STABLEFLY 
In the Southwest the stablefly has been more abundant and has caused more 
injury during 1040 than at any other time during the' last 4 years. Reports 
have been received from dairymen, livestock breeders, and feeders, and hog 
raisers that they have had an unusual amount of stablefly annoyance during the 
1040 fly s eason. Complaints were common from residents of Dallas that they 
were driven indoors by the bites of stabloflios and that pet dogs suffered 
sore ears as a result of the bites of these flies. Dairy cattle and especial!; 
young calves were severely annoyed, practically all year long. At times as 
many as 400 stableflies per animal were - estimated during the late afternoon 
hours. The season was the longest ever noticed in the vicinity of Dal la, s. 
As late as the first week in December thousands of engorged adults were notice: 
on the walls and fences of calf barns and on the animals themselves in the 
vicinity of Dallas. In one instance • during the first week in December calves 
were so annoyed that they sought shelter in fence corners or in dark places 
in the barns. The period of annoyance was approximately S .months. (E. ¥. 
Laake, Bureau of Entomology and Plant Quarantine, U. S. D. A.) 
In northwestern Florida, where it is known as the "dog fly," there were 
no extensive outbreaks, and no deaths were reported from attacks from the flic: 
This was a, distinct contrast to 1939 when it wa.s reported that flies caused 
some : tourists to leave the beaches. One stockman reported that in 1939 about 
500 cattle, or one-fifth of the herd owned by him, became mired and died in 
the swamps where they were driven by the flies. Large but sporadic numbers 
of the flies appeared on beaches in 1940 from August 4 to 6, from September 
5 to 15 , from December 10 to 15 , and from December 20 to 27. The abundance 
of the flies in September coincided with the emergence of adults from nearby 
marine grass deposits on beaches. The occurrences in December when there was
