Parasitism of Sclerodermus alternatusi on Anastrangalia dissimilis
摘要
Abstract
To evaluate the parasitism of Sclerodermus alternatusi on Anastrangalia dissimilis,the mature larvae and pupae of A.dissimilis were used as substitute hosts to study the parasitism of S.alternatusi and the development of its progeny after parasitism in the artificial climate chamber.The results showed that S.alternatusi could parasitize both the mature larva and pupa of A.dissimilis,and the parasitism rate and the progeny emergence rate of S.alternatusi on the mature larvae of A.dissimilis were significantly higher than that on the pupae.There were no significant differences between the mature larva and pupa of A.dissimilis in the pre-oviposition period of female S.alternatusi,and the egg stage,larval stage,pupal stage,and egg‒pupa stage of S.alternatusi progeny.When female S.alternatusi parasitized on the mature larva and pupa of A.dissimilis,their average pre-oviposition periods were 6.15 days and 6.29 days,the duration of the progeny egg stage were 3.71 days and 3.90 days,the duration of larva stage were 7.13 days and 7.22 days,the duration of pupa stage were 17.92 days and 17.78 days,and duration of egg-pupa stage were 28.76 days and 29.00 days,respectively.Both the female progeny number and the total progeny number of S.alternatusi parasitized on the mature larvae of A.dissimilis were significantly higher than that parasitized on the pupae of A.dissimilis.The number of female progeny S.alternatusi developed on the mature larvae and pupae of A.dissimilis were 32.00 and 19.28 per host,the number of the progeny were 33.68 and 20.56 per host,respectively;and all the differences between the mature larva and pupa were significant.While,the number of male progeny showed no significant differences between the mature larva and pupa of A.dissimilis,and the average number of male progeny were 1.68 and 1.28 per host,the male progeny proportion showed significant differences,and they were 5.08%and 6.28%,respectively.Using the mature larva of A.dissimilis as alternative host to breed S.alternatusi,the emergence rate of progeny was higher,the number of female progeny and the total number of progeny were more,and the breeding effect of mature larvae was better than that of pupae.This study result can provide new references for artificial breeding of S.alternatusi.关键词
