The specific status ofCtenopseustis obliquana pheromone-types I, II, and III has been more fully examined. Females of types I and III produce a mixture of (Z)-8- and (Z)-5-tetradecenyl acetates (Z8-14:Ac, Z5-14: Ac). The previously reported different ratios of these two components in females of the two types (type I=80∶20, III=90∶10) have been(More)

Two components, (Z)-5- and (Z)-7-tetradecenyl acetates, in the sex pheromone gland of aPlanotortrix excessana sibling species, were found to vary continuously from a ratio of 3∶97 to 71∶29 in individual female moths reared from wild larvae collected around New Zealand. Two laboratory colonies were established from populations representing extremes of these(More)
Through field trials and wind-tunnel studies, we have demonstrated that certain structural features of a sex-pheromone-baited delta trap affect catch of light-brown apple moth,Epiphyas postvittana, males, by influencing behaviors used to enter and exit the trap. Field catch of males was dependent upon length (and width) of the trap, with increases in length(More)
The sex pheromone of aPlanotortrix excessana sibling species was investigated. Females were found to produce eight potential pheromone components: dodecyl acetate, tetradecyl acetate (14∶OAc). (Z)-5-tetradecenyl acetate (Z5-14∶OAc), (Z)-7-tetradecenyl acetate (Z7-14∶OAc), (Z)-9-tetradecenyl acetate, hexadecyl acetate, (Z)-7-hexadecenyl acetate, and(More)
The effects of parameters associated with a Delta sticky trap on the sex pheromone-mediated responses of maleEpiphyas postvittana (Walker) were tested in a wind tunnel. Males flying to a pheromone source landed closer to the source when other males were stuck on the base, suggesting the importance of visual cues in the landing behavior of males of this(More)
