Abstract
In experiments with ultraviolet-light traps operated in a large field in Texas, of which alternate blocks were sown with cotton and either maize or sorghum, 766 males and 1413 females of Heliothis zea (Boddie) were caught between late July and late August 1977 and were marked and released; 7.8% of the males and 6.7% of the females were recaptured. The spatial distribution of recovery in the plots indicated a distance-dilution effect and no apparent effects of the type or phenology of the crop. An average of 2 nights elapsed between the first and second captures of 80% of the marked and recaptured moths. The remaining marked adults may have dispersed out of the area after 2 days, despite the presence of cotton in an attractive phenological state, or they may have lived for only 2 days; the possibility of adverse effects of the mark-and-recapture technique on these moths is suggested
