为探明哥德恩蚜小蜂对螺旋粉虱的控制效能,研究了不同温度(16℃、20℃、24℃、28℃和32℃)下哥德恩蚜小蜂对螺旋粉虱的寄生功能反应.结果表明,在供试温度范围内,该功能反应均符合Holling-Ⅱ和Ⅲ模型,其中在28℃时寄生效能最大.在同一温度下,随着螺旋粉虱密度的增加,寄生量增加,搜寻效应减弱.此外,哥德恩蚜小蜂个体间存在种内干扰作用,随着自身密度增大,相互干扰作用增强.在16~32℃范围内,Hassell 模型 E=QP?m 均能够较好地反映出不同寄生蜂密度条件下对螺旋粉虱的寄生情况.在16~28℃之间,随着温度升高,搜索能力和相互干扰作用增大,32℃时则有所下降.

@@@@To explore the control capacity of Encarsia guadeloupae against Aleurodicus dispersus, this paper studied the functional response of E. guadeloupae to A.dispersus at different temperatures (16 ℃, 20 ℃, 24 ℃, 28℃, 32 ℃). Functional response of the parasitism fitted well with Holling-Ⅱ and Holling-Ⅲ formulas at the range of the tested temperatures. At 28 ℃, parasitic efficiency reached the maximum, and with the increase in density of A. dispersus, the parasitic capacity of E. guadeloupae increased but searching rate decreased. Strong interference existed in the wasp, which increased with the increasing density of E. guadeloupae. Under the 5 tested temperatures, Hassell equation (E=QP?m ) described parasitism in relation to parasitoid density. The search capability and interference effects increased with the rise of temperature within 16—28 ℃, and then decreased at 32 ℃.
