檬果小黃薊馬抗藥性及其防治管理研究

Abstract

小黃薊馬 (Scirtothrips dorsalis Hood) 近幾年在檬果 (Mangifera indica Linn.) 上發生嚴重，已成為影響當前台灣檬果品質和產量的關鍵害蟲。由於薊馬的世代短、繁殖力高與分散能力強，以及農民的用藥習慣，造成該蟲對多種防治藥劑的感受性下降。本研究探討屏東和台南地區檬果小黃薊馬對登記可使用之殺蟲劑的感受性，以瞭解此等害蟲在不同地區田間對殺蟲劑的感受程度，以提供農民適當的用藥資訊，並研擬適當的管理策略，期能緩解目前小黃薊馬在檬果上的危害。 Chilli thrips, Scirtothrips dorsalis Hood, has been a serious pest of mango (Mangifera indica Linn.) in Taiwan. Its short generation, high fecundity, and high migration ability cause the occurrence of resistance to many insecticides. This research examined the susceptibility of chilli thrips to registered insecticides on mango in Pingtung and Tainan areas, and analyze their differences. In order to reduce the damage rate on mango fruits, we proposed the tactics for management of chilli thrips.
