摘要
本文报告了高温季节茶尺蠖核型多角体病毒对其宿主繁殖的影响。结果表明,免于病死的雌性蛹、成虫的卵巢发育进度与对照相比,无显著性差异;3龄末和4、5龄初饲毒后,化蛹率与羽化率极显著下降,交配率一股明显下降,而羽化成虫的产卵前期、寿命、产卵量、总怀卵量及卵孵化率与对照相比并无显著差异。成虫饲毒后,繁殖力不受影响。
Effect of the nuclear polyhedrosis virus from Ectropis oblioua hypulina Wehrli (EoNPV) on the reproduction of tea geometrid under high temperature condition in July and August was reported. The results indicated: The development rate of ovaries in female pupae or adults survived from the viral infection was no significantly different from that of the healthy ones; Fed with the virus at the late of the 3rd instar, the beginning of the 4th or 5th instar, both of the pupation and emergence rate were reduced distinctly, and the mating rate was generally decreased, but there was no significant difference between the preoviposition period, lifespan, fecundity, total number of eggs or egg hatchability of the female adults survived from the infection and that of the check ones. When the healthy adults were fed with the virus, their reproduction was not affected significantly.
