摘要：[目的]为了明确不同虫态的麻竖毛天牛(Thyestilla gebleri)对松褐天牛肿腿蜂(Sclerodermus alternatusi)寄生行为和子代发育的影响,进一步筛选和高效利用替代寄主。[方法]利用麻竖毛天牛老熟幼虫和蛹作为繁蜂寄主,比较松褐天牛肿腿蜂对两种虫态麻竖毛天牛的寄生率、子代发育历期、子代羽化率和数量的差异。[结果]松褐天牛肿腿蜂可寄生麻竖毛天牛的幼虫和蛹,寄生率无显著差异。然而,用麻竖毛天牛幼虫繁育松褐天牛肿腿蜂时子代蜂羽化率为93.33%,显著高于麻竖毛天牛蛹作繁蜂寄主时的57.69%。用麻竖毛天牛幼虫和蛹繁育松褐天牛肿腿蜂时,雌蜂产卵前期分别为6.63 d和6.43 d,两者无显著差异;其子代的卵期、幼虫期、蛹期及幼期历期均无显著差异,分别平均为4.34 d和4.57 d、8.34 d和8.52 d、19.89 d和20.07 d及32.61 d和33.40 d。用麻竖毛天牛幼虫繁育的松褐天牛肿腿蜂的子代雌蜂数量和子代总数为39.50头和41.18头,用麻竖毛天牛蛹繁蜂时分别平均为30.80头和32.20头,均存显著差异。在两种虫态寄主上育出的松褐天牛肿腿蜂雄性子代数无显著差异,分别平均为1.96头和1.40头;雄性比亦没有显著差异,分别平均为5.00%和4.45%。[结果]用麻竖毛天牛老熟幼虫作寄主时,松褐天牛肿腿蜂子代羽化率更高,繁育得到的子代数量更多。麻竖毛天牛蛹可作为替代寄主繁育松褐天牛肿腿蜂,但繁蜂效率低于天牛幼虫。
[Objective]To compare the differences of parasitism and progeny development of Sclerodermus alternatusi on different stages of Thyestilla gebleri.[Method]The parasitism rate,developmental duration,female and male progeny number,male progeny proportion of S.alternatusi parasitized the larva and pupa of T.gebleri were investigated.[Result]The results showed that both the larva and pupa of T.gebleri could be parasitized by the bethylid,and the parasitism rate on different stages of T.gebleri showed no significant difference.Successful emergence rate of parasitoid offspring showed significant difference on different stage of T.gebleri,93.33%and 57.69%emergence rates were observed on the larva and pupa of longhorn-beetle.The pre-oviposition period of female wasp,egg stage,larval stage,pupal stage,and immature stage of wasps'offspring showed no significant differences on the larva or pupa of host,T.gebleri.The average pre-oviposition periods of female wasps were 6.63 d and 6.43 d when they were inoculated on the larva and pupa of cerambycid host,respectively.The average durations of offspring egg,larval,pupal,and immature stage were 4.34 d and 4.57 d,8.34 d and 8.52 d,19.89 d and 20.07 d,32.61 d and 33.40 d,respectively.The number of female progeny and the total number of offspring were 39.50 and 41.18 when the parasitoid parasitized on the host larva,respectively;and the average numbers were 30.80 and 32.20 when the parasitoid were bred with host pupa.Both had significant differences.There was no significant difference in the number of male progeny when the foundress parasitized on host larva or pupa,with an average of 1.96 and 1.40.The male proportion was also not significantly different,with an average of 5.00%and 4.45%,respectively.[Conclusion]Emergence rate and female progeny quantity of parasitoid parasitized the T.gebleri larva are much higher than the beetle pupa was used as host.Using the late-stage larva of T.gebleri as alternative host can result in the highest fitness in the mass-rearing of S.alternatusi.
