-65- 
lower incidence in the more northern counties. During January specimens 
were identified from Georgia as Cochliomyia americana C. & P. from 
Brooks and Lowndes Counties on the southern "border in the central part 
• of the State, and Effingham County, on the Georgia-South Carolina State 
line. Luring the third week of February screwworms were again identi- 
fied from Brooks County. The situation in Florida differs from that of 
last year in that the low point occurred during the last week in December 
for last winter and during the third week in February for the preceding 
winter. At the present time screwworms have a higher incidence and are 
more evenly distributed in Florida than they were at this time last year. 
In Texas the situation is somewhat encouraging in that shearing of goats 
advanced ahead of the spread of the pest so as to orevent a build-up 
from this source-. Cases are present, however, where shearing of sheep 
is now getting under way and efforts are being made to prevent build- 
ing up a large population of the pest in such injuries. As yet screw- 
worms have not been found in localities west of Del Rio, Tex., or in any 
of the other -Southwestern States. A few cases were found in the canyons 
of Uvalde County, but there is yet no evidence that they are present on 
the Edwards Plateau. At San Antonio one local infestation was apparently 
stamped out. Counties near the Rio Grande between Del Rio and Browns- 
ville, Tex., show the greatest number of cases for the winter months, as 
well as for March. For all counties in southern Texas there were re- 
ported for December 1,121 cases; for January, 675 cases; for February, 
29S cases; and from March 1 to 2o, : 1,5^0 cases. During the last week 
of March H69 cases were reported, as compared to 395 during tho pre- 
ceding week. Stockmen in Texas are screwvorm conscious and are prevent- 
ing a build-up of population of the pest in young animals born during 
this season. 
Texas. E. F. Knipling (March 2H): Ranchmen in Hidalgo County, in the 
southern tip of Texas, report increased activity of the screwworm fly 
during the last week of February. The most common infestations were in 
the navels of young calves. Only a few cases were reported during the 
period from January 1 to the end of February. 
A. W, Lindquist (March 2*0'. No infestations of animals were observed 
in the vicinity of Uvalde from January l6 to February 28. On March 1, 
two sheep and one calf were found to be infested. 
W. L. Barrett (March 2U) : A survey of the abundance of C. americana 
along tho lower Rio Grande indicates that the flies were more numerous 
along the Rio Grande from Laredo, in Webb County, to Rio Grande City, 
in Starr County, during the period from January 15 to February 15. Con- 
tinuing this survey west to Presidio, from March 8 to 12, no flies or 
screwworm cases were found west of Del Rio, Vol Verde County. 
Arizona. C. C. Deonier (March 20): In a survey on March 20, four cases "f 
screwworms were reported from the Arizona-Mexico line, 30 miles west of 
Nogalos, near the central part of the State.
