The responses of European corn borer, Ostrina nubilalis (Hübner), males in a flight tunnel to sex pheromone, [11-tetradecenyl acetate (97:3, Z:E)] was dependent upon the context in which the males were exposed to the stimulus. Males, held individually in isolation before being exposed to pheromone, flew upwind in the pheromone plume and landed on the pheromone source significantly more often than males caged with other males before exposure to the pheromone. When groups of males were simultaneously exposed to female sex pheromone, they responded, on a permale basis, with significantly more upwind flights to pheromone and intense behavior near the pheromone source than did males exposed to the pheromone individually. Heightened intensity of male response in group flight was independent of whether the males were individually isolated or caged with other males before being exposed to the pheromone. The enhanced behavioral output of males responding to pheromone in groups may represent an evolutionary adaptive advantage in instances where several males are simultaneously pursuing a single calling female.

The sexual attractancy of female Heliothis virescens (F.) which had been cultured in the laboratory for 40 generations and of hybrid and backcross females (H. subflexa ♀ X H. virescens ♂) was determined and compared with the attractancy of wild female H. virescens. In field tests, females reared (< 1 generation) from field-collected larvae were significantly (P ≤ 0.05) less attractive to wild males than were females reared in the laboratory for 40 generations (HVL-40), but the attractancy of females reared in the laboratory for 1 or 41 generations did not differ significantly. The attractancy of H. virescens females from generations 40, 41 and BC females from generations 41, 42 or 179, 180 did not differ significantly in any of five tests, except in test three, where more wild males were attracted by HVL-40 than by BC-41 females. Continuous backcrossing of the female hybrid (180 generations) did not affect the attractivity of the female to the wild males. The attractancy of lab-reared H. virescens (except for generation 40) or hybrid BC virgin females, regardless of generation, to wild H. virescens males was not significantly different from that of the synthetic female sex pheromone Z-11-Hexadecenal: Z-9-tetradecenal (14.6:1). The data indicate the attractancy of H. virescens and BC virgin females to wild males may be enhanced by continuous laboratory rearing. These findings are important in population dynamic studies in which lab-reared females are used and in determining the ratio of BC to wild H. virescens females needed to suppress a given population of H. virescens.

The racemate and individual enantiomers of 2-fluoro-Z-11-tetradecenyl acetate (2F-Z-11), analogs of a European corn borer moth, Ostrinia nubilalis (Hübner), female sex pheromone were compared with the natural pheromone, Z-11-tetradecenyl acetate, in field trapping experiments, flight tunnel studies, mating disruption assays and electrophysiological experiments. While the racemate and R-2F-Z-11 mimicked the natural female sex pheromone, they were not more biologically potent than the pheromone. The S-2F-Z-11 was largely ineffective in all assays and was, therefore, incompatible with the pheromone receptor system.
