摘要：松褐天牛肿腿蜂属卵育型寄生蜂,雌蜂补充营养后卵巢开始发育,且雌蜂可多次产卵并寄生多头寄主。为明确松褐天牛肿腿蜂雌蜂不同产卵批次下的寄生能力和子代发育情况差异,本研究测定了松褐天牛肿腿蜂雌蜂在不同产卵寄生批次下的寄生率、寄生成功率、子代发育历期、子代数量和雄性比例等生活史参数的变化。结果表明:以麻天牛幼虫为寄主,松褐天牛肿腿蜂雌蜂最多可完成4次寄生行为,85%的雌蜂能完成2次寄生,但仅有31%的雌蜂能完成3次寄生,可能完成4次寄生的雌蜂仅有4%。随着产卵批次的增加,母蜂寄生能力逐渐减弱。松褐天牛肿腿蜂雌蜂不同产卵批次间其子代幼虫历期、蛹历期均差异显著,以第1批次最长,第4批次最短。不同的产卵批次间子代雌蜂数量、子代雄蜂数量均差异显著。第1和第2产卵批次中雌蜂平均数量为40.2头和35.1头,较后续产卵批次更多;这两个产卵批次育出雄蜂数量均少于10头。第3个产卵批次中子代雌蜂数量锐减,且雄蜂比例超过60%;第4批次时,子代全为雄性。松褐天牛肿腿蜂的平均最大产雌数为80.6头。以上研究为松褐天牛肿腿蜂的人工繁育和利用提供参考。
Sclerodermus alternatusi is a synovigenic parasitoid in which oogenesis takes place after the female is stimulated by feeding on a host,and this is a successive process.Generally,one female parasitoid can complete several times of parasitism and thus parasitize more than one hosts in its life span.In order to compare the differences of adult parasitism ability and offspring development of S.alternatusi in different adult oviposition times,the female parasitism rate,successful parasitism rate,progeny developmental duration,brood size,and male proportion were investigated in the laboratory conditions.The results showed that S.alternatusi female could complete four times of parasitization to the host,Thyestilla gebleri larvae.There were 85%of female parasitoids could complete two times of parasitization,but only 31%and 4%of females could complete three or four times of parasitization.The parasitic ability of the female parasitoid gradually decreases with the increase of the oviposition times.The durations of egg stage showed no significant difference in different oviposition times.However,the larval stage and pupal stage of the offspring were significantly different in different oviposition times,which displaying the longest in first oviposition time and the shortest in fourth oviposition time.The numbers of female and male offspring were significantly different among different oviposition times.The female offspring numbers were 40.2 and 35.1 in the first and second oviposition time,respectively.The numbers of male offspring were also less than 10 in these two oviposition times.The numbers of female offspring were sharply declined in the third oviposition time,over 60%of offsprings were males.Moreover,all of the offspring were males in the fourth oviposition time.The mean number of female offspring of a single S.alternatusi adult was approximately 80.This study provides new references for rearing and using the S.alternatusi to control the longhorn beetles.
