摘要

本研究於2003 年至2006 年間，於彰化縣埔鹽、田尾鄉花椰菜田，比較不同型式誘蟲器對小菜蛾之誘捕效果。結果顯示商品化誘蟲器如中改式誘蟲器、黃氏美人計誘蟲偵測器，及誘捕果實蠅的誘蟲器如捕蠅器、金穩蠅麥氏誘蟲器、安啦誘蠅器等，不適合用於誘捕小菜蛾。設計多款的誘蟲器型式，以單層上衝式寶特瓶誘蟲器誘餌置於誘蟲器下區，為對誘捕小菜蛾有潛力之乾式誘蟲器型式。不同型式黏膠誘蟲器對小菜蛾之誘捕效果，以翼型黏膠誘蟲器對小菜蛾之誘捕效果，較圓筒型黏膠式誘蟲器為佳。小菜蛾性費洛蒙誘餌置於翼型黏膠誘蟲器的上蓋或下底，不會影響誘蟲效果；誘捕的小菜蛾蟲體主要分布於下底黏板。寶特瓶水式誘蟲器對小菜蛾之誘捕效果，以兩倍入口的雙層寶特瓶水式誘蟲器對小菜蛾誘捕效果，相當於翼型黏膠誘蟲器，可作為小菜蛾的水式誘蟲器。

We compared the trapping efficiency of 5 commercial traps as well as various dry traps and sticky traps that had been newly designed in this study. In all cases, traps were baited with sex pheromones, and we compared their ability to capture diamondback moths (DBMs), Plutella xylostella, in cauliflower fields of Puyan and Tianwei, Changhua, Taiwan from 2003 to 2006. We found that none of the 5 commercial traps, including TDAR trap, Hwang's beauty fly trap, Fly Trap, Golden McPhail fly trap and Victor fly trap, were not suitable for trapping DBMs when baited with sex pheromones. Conversely, of the many types of dry traps we designed and tested, the 1-up-PET trap appears to efficiently capture DBMs when the lure is placed in the lower section of the trap. In addition, the trapping efficiency of the wing sticky trap was found to be better than that of the Cylinder sticky trap. For the wing sticky trap, the location of the DBM lure (i.e., either on the bottom layer or on the cover layer of the trap) had no influence on trapping efficiency; however, captured moths were mainly found on the bottom layer. Finally, our data indicates that the PET water trap (i.e., a double layer PET water trap with two entrances) may also be feasible for trapping DBMs.
