FIELD TRAPPING OF THE DIAMONDBACK MOTH PLUTELLA-XYLOSTELLA USING SYNTHETIC SEX ATTRACTANTS LEPIDOPTERA, PLUTELLIDAE

Mixtures of Z-11-hexadecenal and Z-11-hexadecenyl acetate used as lures were as attractive to males of Plutella xylostella as 10 virgin females, based on field trapping tests. The best binary lure tested was 100 μg 7:3 aldehyde:acetate dispensed from red rubber septa and the optimal trap height was 0.3 m. Virgin females and synthetic lures both attracted Cry-modes devastator males in addition to P, xylostella. Several olefins were tested as additives to synthetic lures; attraction of both species was inhibited by Z-9-tetradecenal and by Z-9-tetradecenyl acetate. © 1979 Entomological Society of America.
