Abstract
跳小蜂科（Encyrtidae）為膜翅目（Hymenotera）小蜂總科（Chalcidoidea）中之一科，其寄主範圍絕大多數為農林害蟲之重要天敵，其中對於屬於半翅目介殼蟲總科之粉介殼蟲更具實際應用之防治功效。生物防治（包括捕食性及寄生性天敵），對於近年入侵臺灣的木瓜秀粉介殼蟲（Paracoccus marginatus Williams and Granara de Willink, PMB）在全世界已具實際應用之防治功效，本研究將實驗室飼育所得的木瓜抑蝨跳小蜂（Acerophagus papayae Noyes and Schauff），定期釋放至有機栽培溫室內之狀況。經調查顯示，除可建立其族群外，並可配合其他有機防治方法 ，達到抑制木瓜秀粉介殼蟲族群之效果。當粉介殼蟲密度較少時，亦可維持 32.0-64.4% 寄生致死率，且無果實被害情形並達全年供貨。木瓜抑蝨跳小蜂具專一性、移動速度快、耐高溫、寄生齡期廣（2 齡若蟲至雌成蟲） 等生態特性，不失為具防治木瓜秀粉介殼蟲潛力之寄生蜂。此外，亦開發簡易飼養寄生蜂裝置，此結果可供日後田間應用時之參考。
The Encyrtidae is one of the Chalcidoidea (Hymenotera), and are the important natural
enemies of pests, especially in the control of mealybugs. Biological control (including predatory and parasitic natural enemies) of papaya mealybug (Paracoccus marginatus Williams and Granara de Willink, PMB) which recent invaded Taiwan in the world has a practical application of the prevention and treatment effect. In this study, the parasitoids (Acerophagus papayae Noyes and Schauff) were released regularly into the organic cultivated greenhouse. According to the survey, in addition to the stablishment of its population, and can be combined with other organic control methods to achieve the inhibition effect of papaya mealybugs population. When the density of papaya mealybugs is below 10%, it can maintain the parasitic fatality rate of 32.0-64.4% without damage of fruit. The parasitoids (A. papayae) with specifi city, fast movement, high temperature resistance, parasitic range wide (nymph2nd to female adult) and other ecological characteristics, is a parasitic wasp to control the papaya mealybugs.
