臺灣綠蘆筍薊馬種類之調查

Abstract

由本省中南部綠蘆筍專業區所採得的薊馬種類，有七種，為①褐腹薊馬Frankliniella intonsa Tryhom②禾花薊馬Frankliniclla tenuicornis Uzed③蔥薊馬Thrips tabaci Lindeman④花斑薊馬Thrips florus Kurosawa⑤腹帶薊馬Sericothrips abdominalis Kurosawa⑥茶黃薊馬Sericothrips dorsalis Hood⑦Pseudoden-drothrips mori Niwa。前4種在綠蘆筍園普遍發生，餘3種在綠蘆筍上發生甚少。以上七種薊馬之形態、分佈、寄主均有分別說明。由於此等薊馬對綠蘆筍的嗜好性，在乾燥季節，如有嫩莖、嫩芽生長即能找到棲息於綠蘆筍嫩芽與花瓣及幼筍嫩莖上之蟲體，因而污染蘆筍，影響品質及外銷。又由於薊馬對綠蘆筍取食與產卵的選擇性之關係，通常在田間的棲羣變動，是受綠蘆筍的生長所控制。且因蟲體劉濕度之抵抗較弱，降雨季節之6~9月間在田問發生密度亦受雨量所影響。 There were 7 species of thrips infesting green asparagus recorded from Taiwan, namely 1. Frankliniella intonsa Tryhom, 2. F. tenuicornis Uzed, 3. Thrips tabaci Lindeman, 4, T. florus Kurosawa, 5. Sericothrips abdominalis Kurosawa, 6. S. dorsalis Hood and 7. Pseudodendrothrips mori Niwa. The first 4 species were very common but the last 3 species rarely found. Synonyms, morphology, distribution and host plants were briefly described under each species. Due to the insect bodies left on asparagus sprout tainting processed materials and reducing market value as the trouble problem of asparagus industry at present.
