中文摘要 | 經調查結果中部地區為害玫瑰之薊馬,有臺灣薊馬(Frankliniella intonsa)、 小黃薊馬( Scirtothrips dorsalis )、中國薊馬( Haplothrips chineinsis )、 花薊 馬( Thrips hawaiiensis )及腹鉤薊馬( Rhipiphorothrips cruentatus )等五種。 其 中臺灣花薊馬、中國薊馬、花薊馬,吸食花部,並產卵於花瓣造成花器受害;小黃薊馬為害 嫩葉及花部;腹鉤薊馬只在玫塊中、老葉聚集為害。在五種薊馬中以臺灣花薊馬、小黃薊馬 和中國薊馬最為常見,尤以臺灣花薊馬及小黃薊馬之為害最為嚴重。小黃薊馬多發生於八月 至翌年四月;臺灣花薊馬幾乎全年均有出現,族群高峰期在九∼十一月及二∼五月。藥劑篩 選結果,所有供試藥劑對躲藏在玫瑰花蕾內之臺灣花薊馬及中國薊馬,並無明顯防治效果; 對小黃薊馬則以 2.4 % decamethrin S.C.1000 倍、24 % methomyl S.1000 倍及 9.6 % imidacloprid S.L.4000 倍等三種藥劑防治效果較佳。 |
英文摘要 | Five species of thrips, Frankliniella intonsa (Trybom), Scirothrips dorsalis Hood, Haplothrips chineinsis Priesner, Thrips hawaiiensis (Morgan) and Rhipiphorothrips cruentatus Hood, were recorded as the insect pest on rose in midwest part of Taiwan. High population density of these thrips occurred in the blooming stage. Frankliniella intonsa, Haplothrips chineinsis and Thrips hawaiiensis aggregated in the flowers, and damaged flowers by consuming and depositing eggs on them. Scirtothrips dorsalis and Rhipiphorothrips cruentatus comsumed leaflet and caused brown spots on them. Frankliniella intonsa occurred all year round in midwest part of Taiwan and its population density peaked between September to November and February to May. Scirtothrips dorsalis between August to next April. |
