| 摘 要： | 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。

| Abstract: | With Cnaphalocrocis medinalis larvae as host,the paper studied the parasitic functional response of Apanteles cypris in laboratory.The result showed that the response of A.cypris fitted Michaelis-Menten type II model Na =AN0 /(F+N0),and parasite potential per female in 24 hour A=10.7528,half saturated host density F=14.3864.There was stronger intraspecific interference in the parasitic functional response of A.cypris i.e.the number of parasitized larvae decreases with increasing A.cypris density.The relatio... |
