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。 Laboratory tests showed that during the parasitism of Tetraselina chrysalon, the total amount of larvae fed on the stem borer was significantly reduced by 36.75% compared to the control larvae, but not during the parasitism of the bee larvae. There was no significant difference in the amount of food that had been parasitized between the stem borer and control larvae. Based on the parasitized 4th and 5th instar larvae, the larvae growth rate was measured. Larvae borer larva growth rate increased after parasitized by B. calyciflorus, but larval net growth rate did not include the decline of the body: the frequency of host molting decreased but could not pupate.
