赤帶薊馬 (Selenothrips rubrocinctus) 對荔枝葉片之危害與殺蟲劑藥效測試

Abstract

赤帶薊馬為廣布於世界熱帶與亞熱帶地區的多食性害蟲，有危害可可、腰果、芒果、酪梨、番石榴等多種果樹紀錄，本研究則為首次於台灣報導赤帶薊馬危害荔枝紀錄。嘉義地區於2014年7月至11月間持續溫暖、乾燥天候環境適於赤帶薊馬大量發生，並於當年11月於農業試驗所嘉義農業試驗分所荔枝園觀察到「黑葉」、「糯米糍（73-S-20）」、「台農3號（玫瑰紅）」、「台農5號（紅寶石）」、「台農7號（早大荔）」等商業品種的葉片受赤帶薊馬危害，使葉片上表皮與中肋具青銅色斑駁狀危害食痕。 Red banded thrip (＂Selenothrips rubrocinctus＂) is a polyphagous pest widely distributed in tropical and subtropical regions in the world. The thrip attacks various fruit trees such as cacao, cashew, mango, avocado, and guava in certain habitats. In this study, we first recorded the infestation of red banded thrips on litchi in Taiwan. We observed the damage on leaves of 'Hak Ip', 'No Mai Tsz (73- S-20)', 'Tainung No. 3 (Rose Red)', 'Tainung No. 5 (Ruby)', and 'Tainung No. 7 (Early Big)' litchis in the orchard at Chiayi Agricultural Experiment Station of Taiwan Agricultural Research Institute in November, 2014, after a warm and dry period in almost half of year.
