水楊酸甲酯吸引捕食性天敵降低小黃瓜上南黃薊馬(Thrips palmi Karny)數量

Abstract

本研究呈現水楊酸甲酯吸引天敵，並降低小黃瓜上南黃薊馬（Thrips palmi Karny）數量的效果。明顯較高數量的南黃薊馬天敵小黑花椿象（Orius strigicollis Poppius）及中華班腿盲椿象（Campylomma chinensis Schuh），被發現於黃色黏板搭配水楊酸甲酯的處理組，但水楊酸甲酯的效果呈現濃度與季節的差異性。 This study investigates the effectiveness of methyl salicylate (MeSA) to attract natural enemies and to reduce melon thrips (Thrips palmi Karny) population in cucumber plants. High numbers of natural enemies of melon thrips, namely, Orius strigicollis Poppius and Campylomma chinensis Schuh, were trapped on the yellow sticky paper baited with MeSA; however, levels of attraction differed with concentration and season.
