松褐天牛肿腿蜂对小灰长角天牛幼虫和蛹的寄生研究
A study on parasitism of Sclerodermus alternatusi(Hymenoptera:Bethylidae)on Acanthocinus griseus(Coleoptera:Cerambycidae)larvae and pupa
摘要
Abstract
[Objective]This study aimed to evaluate the variations in parasitism and progeny development of S.alternatusi on various stages of Acanthocinus griseus.[Method]In this experiment,the swollen leg beetle parasitoid was introduced to the larvae and pupae of the small gray longhorn beetle at a ratio of 1:1,and its ability to produce offspring was observed,along with the recording of the development of the offspring and the statistical analysis of its numbers.[Result]The findings demonstrated that there were no discernible differences in the parasitism rate and the emerging rate,and the parasitism rate were 75%and 85%,and the emerging rate were 66.67%and 70.59%.There were no discernible differences in the late-stage larva and pupa of A.griseus in the pre-oviposition period of the female wasp,the egg stage and the pupal stage of the wasps'progeny;their average pre-oviposition periods were 8.53 and 7.94 days,respectively,and the egg stage were 6.07 and 6.19 days,and the pupal stage were 17.80 and 17.50 days.There were significant differences in the larval stage and immature stage,and the larval stage were 6.31 and 5.43 days,and the immature stage were 30.30 and 29.00 days.Both the female offspring number and total offspring number of wasp parasitized the longhorn-beetle late-stage larva were slightly higher than parasitized the longhorn-beetle pupa.28.30 female offsprings and 29.70 offsprings were obtained when the parasitoid developed on the late-stage larva of A.griseus;while 25.50 female offsprings and 27.00 offsprings were obtained as the parasitoid developed on the pupa of A.griseus.However,the male offspring and male proportion showed no significant differences as the wasp used these two types of hosts,1.40 and1.50 male offsprings were obtained as the parasitoid developed on the late-stage larva and pupa of A.griseus,and the male rate were 5.28%and 5.71%.[Conclusion]This study showed that both the late-stage larva and pupa of A.griseus could be rearing S.alternatusi as a substitute host.关键词
