Abstract
FemaleHeliothis virescens (F.) moths reared from larvae on diet treated (0.1%) with experimental chemosterilants or the dietary additive, DL-leucine, were used as bait in sex lure traps in field cages when they were 2–4 nights old. Catches of untreated released males were used to determine relative attractiveness of the chemically treated females. The catch (indicating quantity or production frequency of pheromone) was significantly increased whendl-leucine had been fed in the larval diet, and sulfanilamide caused a slight increase in female attractiveness. The catch of males was significantly reduced when either reserpine or quercitin had been added to the diet. The other chemicals, bisdicumarol, 2,4-dichlorophenoxyacetic acid, β-sitosterol, and dihydrocholesterol, did not significantly affect the catch.
