摘　　要：研究了中华草蛉Chrysopa sinica（Tjeder）对温室白粉虱Trialeurodes vaporariorum（Westwood）的捕食作用。结果表明，中华草蛉幼虫对温室白粉虱卵的功能反应呈HollingⅡ型。中华草蛉1龄、2龄和3龄幼虫对温室白粉虱卵的理论日最大捕食量分别为131．20、375．94和490．20粒。在20-40％内，30％时中华草蛉2龄幼虫对温室白粉虱卵寻找效率（功能系数）最高，达1．2885；处置时间最短，为0．0019d。The predation of Chrysopa slnica on the greenhouse whitefly, Trialeurodes vaporariorum was studied in the laboratory. The functional response of C. sinica larvae to eggs of the glasshouse whitefly was determined as Holting＇s type Ⅱ. The maximal theoretical predation numbers of 1st, 2nd and 3rd instar larvae of C. sinica to eggs of the greenhouse whitefly were 131.20, 375. 94 and 490. 20 per day respectively. For 2nd instar larvae of C. sinica, the predation efficiencies （E） of predator varied with temperatures under different constant conditions within the range of 20-40℃. At the temperature of 30℃ , the search rate （a） was the highest and reached 1. 288 5. On the other hand, the handling time （Th） was the shortest, i.e., 0. 001 9 day .
