本文报道海氏桨角蚜小蜂Eretmocerus hayati在室内对不同寄主密度下的B型和Q型烟粉虱Bemisia tabaci寄生和取食情况,并比较了该蜂对两种生物型烟粉虱功能反应的差异.结果表明,海氏桨角蚜小蜂对两种生物型烟粉虱的寄生率和致死率可分别达到60%和70%以上,平均每日最大致死量可达40头烟粉虱若虫.该蜂对两种生物型烟粉虱的功能反应曲线符合Holling II型,随寄主密度的增加对烟粉虱若虫的寄生和致死数量均增加直至达到每日最大致死数量,而寄生率和致死率则随寄主密度的增加而显著下降.该蜂对两种生物型烟粉虱的功能反应没有显著的差异.

Functional responses of the parasitoid Eretmocerus hayati Zolnerowich and Rose (Hymenoptera: Aphelinidae) to the increase of host density of the whitefly, Bemisia tabaci (Gennadius) (Hemiptera:Aleyrodidae) biotype B and Q was investigated in the laboratory. The results showed that the functional response could be described well by Holling II type equation on both B and Q biotype hosts and no significant difference was found between the two biotypes. The mortality of whitefly caused by parasitism and feeding of the parasitoid reached over 70% and the maximum number of hosts parasitized and fed reached 40 in a day. These laboratory results indicated a high potential of E. hayati as a biocontrol agent for both the B and Q biotypes of B. tabaci.
