Abstract
Trapping studies were conducted in southern Texas during the fall of 1975 to compare distribution and diurnal activity periods of released and native screwworm flies [ Cochliomyia hominivorax (Coquerel)]. In general the distribution of released and native screwworm flies corresponded. Most sterile flies were captured from 1–6 PM (or 12–5 PM) during 4 test periods. Wild flies were active throughout the entire day during the 1st 2 test periods (Sept. 29, 1976–Nov. 13, 1976), and mainly from 1–6 PM (or 12–5 PM) during the final 2 test periods (Nov. 18, 1975–Dec. 12, 1975). It appeared that the screwworm strain then being released was not as active at low temperatures as native screwworm flies. Tests in the spring and fall of 1976 with a replacement strain, designated 009, indicated that the deficiency in activity in cool weather may have been corrected.
