印度棗害蟲之生態防治

Abstract

印度棗之栽培主要分佈於臺灣高雄縣大社鄉及燕巢鄉，害蟲種類至 1988 年7月止共發現有 6 目 2 類，包括 28 種害蟲及動物，以柑桔粉介殼蟲 (Planococcus citri (Risso))、印度棗葉蟬 (Ouadria pakistanica (Ashmead))、盲樁象 (Campylomna lividicornis Reuter)、白斑星天牛 (Anoplophora maculata (Thomson))、小白紋毒蛾 (Orgyia poskica Walker) 及柑桔葉蟎 (Panonychus citris (McGregor))為害最嚴重，粉介殼蟲主要來自番石榴之感染，於 10 月至次年 3月為害枝、葉及果實，與螞蟻共生互虐為害，益增加防治困難。 Surveys of insects and other pests on Indian jujube were carried out from 1985 to 1988 in southern Taiwan.
