台灣南部長豇豆園內薊馬類 (Thysanoptera: Thripidae) 的取樣計畫

Abstract

長豇豆 (Vigna unguiculata ssp. sesquipedalis, yardlong bean) 為台灣重要的豆科蔬菜之一，薊馬類 (Thysanoptera: Thripidae) 是長豇豆的主要害蟲。為決定何時噴施農藥，因此需建立長豇豆園內薊馬類的取樣計畫，以掌握施藥防治薊馬的時機。本研究調查台灣南部長豇豆園中長豇豆花朵內的薊馬種類為豆花薊馬 [Megalurothrips usitatus (Bagnall)] 與台灣花薊馬 [Frankliniella intonsa (Trybom)]。 Yardlong bean (Vigna unguiculata ssp. sesquipedalis) is one of the important legume vegetables in Taiwan. Thrips (Thysanoptera: Thripidae) is a group of the major pests of yardlong bean. To decide the best timing to use pesticides, it is necessary to establish a sampling plan for thrips in the yardlong bean farm and to gain an insight into the timing of pesticide application for controlling thrips. In this study, two thrips, Megalothrips usitatus (Bagnall) and Frankliniella intonsa (Trybom), were investigated in yardlong bean flowers in the farms in southern Taiwan.
