Abstract
有關柑桔紅蜘蛛（Panonychus citri）昆蟲方面之天敵，據中華農學會第48期，筆者之研究報告中，其天敵有小黑瓢蟲Stethorus sp.，小黑隱翅蟲Oligota sp.，草蜻蛉Chrysopa sp.，六點薊馬Scolothrips sexmaculatus及黑薊馬Leptothrips sp. 等五種，然有關柑桔紅蜘蛛在蜘蛛類中之天敵並未提及，故筆者在此再加繼續調查與研究。至目前為止，在柑桔植物上共發現捕食柑桔紅蜘蛛之蜘蛛類天敵也有五種。
According to the present survey, 5 species of predacious mites of citrus red mite have been recorded, namely Typhlodromus finlandicus, Typhlodromus sp. a, Typhlodromus sp. b, Anystis sp., and Pronematus sp. Among them. Typhlodromus finlandicus and Typhlodromus sp. a, were the most active and efficient as the main predators of the citrus red mites. Typhlodromus sp. b Preyed upon the white flies rather than the citrus red mites. Anystis sp. was the largest predator of the citrus red mite, but its population was very small, so that its economic importance may be not considered. Pronematus sp. was a fairly small mite which preyed upon the eggs of the citrus red mites, the efficiency of citrus red mite control was considered fairly well.
