在室内测定了纵卷叶螟绒茧蜂Apanteles cypris对稻纵卷叶螟Cnaphalocrocis medinalis幼虫的功能反应和寻找效应。结果表明,纵卷叶螟绒茧蜂对稻纵卷叶螟幼虫的功能反应可用Michaelis-Menten-Ⅱ型功能反应模型Na=AN0/(F+N0)拟合,一头纵卷叶螟绒茧蜂雌蜂在24h内对稻纵卷叶螟幼虫的寄生潜能A为10.7528头,寄主半饱和密度F为14.3864头。纵卷叶螟绒茧蜂的寄生功能反应有较强的种内干扰作用,即随自身密度的增加,寄生数量逐渐减少。Hassell模型E=QP-m能较好地反映纵卷叶螟绒茧蜂的寻找效应与其自身密度的关系,拟合结果为:E=0.2956P-0.5890。
The functional response and the finding effect of Apanteles cypris on larvae of Cnaphalocrocis medinalis were determined indoors. The results showed that the functional response of C. calycifa to C. medinalis larvae could be fitted by the function model of Michaelis-Menten-Ⅱ Na = AN0 / (F + N0) The parasitism potential of female bees on C. medinalis larvae was 10.7528 in 24h, and the host half-saturation density F was 14.3864. Parasitic leaf borer Chrysalis parasitism functional parasitism has a strong intraspecific interference, that is, with its own density increases, the number of parasitic gradually reduced. The Hassell model E = QP-m can well reflect the relationship between the finding effect and its own density of the Culex pipiens pallens. The fitting result is: E = 0.2956P-0.5890.
