Abstract

Source concentration differences of (Z)-7-dodecen-1-ol acetate, or looplure, were evaluated for field trapping efficiency and electrophysiological responses with male Pseudoplusia includens (Walker), Trichoplusia ni (Hubner) and Rachiplusia ou (Guenné) (Lepidoptera: Noctuidae). Sticky traps baited with 1000 μg of the lure captured a significantly greater (P < 0.05) number of male P. includens and T. ni than any other concentration;R. ou males were caught at a greater rate in traps baited with 100 μg of looplure, significantly more (P < 0.05) than with 1000 μg. Electroantennogram (EAG) studies demonstrated that antennae of male P. includens have a lower response threshold to looplure than either T. ni or R. ou antennae, the latter demonstrating the highest significant threshold of response. No differences in the stimulus-response functions of the three species were detected. © 1982 Plenum Publishing Corporation.
