The Utilization of Predacious Ladybirds for Biolgical Control of Bemisia argentifolii (Homoptera: Aleyroidae)

本計畫之目的是應用小黑粉蝨瓢蟲(Delphastus catalinae)和刀角瓢蟲(Serangium japonicum)生物防治銀葉粉蝨(Bemisia argentifolii).今年度研究重點是試驗如何有效的大量繁殖小黑粉蝨瓢蟲及刀角瓢蟲,以利以後的田間實際應用.第一項是研究聖誕紅為植株飼育銀葉粉蝨供大量飼養小黑粉蝨瓢蟲及刀角瓢蟲.第二項是試驗小黑粉蝨瓢蟲對銀葉粉蝨之捕食量,及食餌對瓢蟲發育之影響.The objective of this research project is the study of rearing of two predacious ladybird beetles, Delphastus catalinae and Serangium japonicum, for biological control of Bemisia argentifolii. The first part is the study of rearing technique for the predacious ladybird beetles. The second part is the observation of the predation of ladybird beetles, and the prey affect the development of beetles
