摘要
室内试验结果表明,在二化螟绒茧蜂寄生期间,寄主二化螟幼虫的取食总量比对照幼虫显著减少36.75％,而在蜂幼虫未啮出寄主体的不同寄生时间内。被寄生的二化螟幼虫和对照幼虫的取食量没有显著差异。通过对被寄生后的4龄和5龄二化螟幼虫生长速率的测定结果表明,被绒茧蜂寄生后的二化螟幼虫生长加快,发育受抑。被绒茧蜂寄生后的二化螟幼虫生长速率增大,但不包含蜂体的幼虫净生长速率下降:寄主蜕皮次数减少而不能化蛹。
The changes on food consumption and development of A. chilonis parasited C. supplessalis were studied. The total amount of food consumption of host 1arvae, compare with contrast, redueed by 36.75％. During the parasitisation, the host larvae grews quickly, but its development rate was restrained. The grweth rate of parasited larvae increased, but the net growth of host larvae decrcased. The times of host—mounting become less, and the host larvae could not develop onto pupa stage.
