SCREWWORM ( Cochliomyia americana C. & P.) 
United States. W. E. Dove- (May J>l)'. The low point for cases occurred during 
the last week of December as compared to the third week of February of 
the preceding year. Localized outbreaks occurring in the line of advance 
in Jefferson County, Fla. , and Camden County, Ga. , were brought under 
control. At Hinesville, Ga. , the first case of the season occurred on 
May 25, which was 25 days later than the first case last year, and-Uo 
days later than the first case of 1935* For 'the U-week period ended 
May 21, there were 2,575 cases representing about one-half million animals 
in Florida. In Georgia 60 cases were reported in the southern counties. 
As yet, cases have not been found in western Florida, South Carolina, 
Alabama, Mississippi, Louisiana, or in eastern Texas. In California no 
screwworms were present in the Imperial Valley during the winter and 
most of the animals are now in the higher elevations without infestations. 
Screwworms are now present in small numbers in these sections, in three 
counties of the southeastern corner of New Mexico, and a few cases are 
occurring in Pima and Cochise Counties, Ariz. Throughout this area there 
is a low incidence of cases. Much of the shearing was completed in ad- 
vance of the spread of screwworms and most of the shear cuts were treated 
with pine tar oil. For the U-week period ended May 21 there were 7»^2U 
cases reported from Texas, representing more than three million animals 
of the infested area. The heavy shipments of feeder stock to Oklahoma 
and Kansas are about completed and stockmen made efforts to ship only 
"clean" animals into these areas.
