摘要: 为明确管氏肿腿蜂Sclerodermus guani Xiao et Wu雌蜂抚育行为付出的代价和收益,本试验以管氏肿腿蜂有、无母蜂抚育为处理水平,观察了管氏肿腿蜂雌蜂抚育行为对母蜂生殖力和子代发育适合度的影响。研究发现,抚育与否,母蜂寿命分别为26.64和28.85 d,二者之间差异不显著,但抚育母蜂的寄生次数最多为2次,显著小于不抚育下的4次,抚育母蜂的子代幼虫数量也显著少于未抚育母蜂。同时,母蜂抚育下子代幼虫的死亡率、化茧蛹率和雌蜂体重分别为9.29%、61.52%、0.64 mg,均显著优于不抚育下的22.04%、27.40%、0.55 mg,提高了子代发育适合度。另外,抚育与否并不影响子代雌性比例和羽化率,抚育子代的雌性比例、茧蛹羽化率和非茧蛹羽化率分别为90.77%、99.57%和79.57%,而未抚育子代的雌性比例、茧蛹羽化率和非茧蛹羽化率分别为87.96%、97.74%和84.45%,但化蛹方式显著地影响子代的羽化率,茧蛹的羽化率比非茧蛹高13%以上。

Abstract: To clarify the costs and benefits of maternal care in parasitoid Sclerodermus guani Xiao et Wu (Hymenoptera:Bethylidae), we investigated the effects of maternal care of S. guani on the fecundity of mother and the development fitness of offspring. The results showed that the lifetime of maternal care wasps was 26.64 d, not different from that of the wasps without maternal care (28.85 d). The number of maternal care wasps'offspring was lower than that of the wasps without maternal care. Furthermore, with maternal care, the development of offspring was improved, the death proportion, cocoon proportion and the weight of maternal care wasps'offspring were 9.29%, 61.52% and 0.64 mg, respectively, which were better than unmaternal care group's (22.04%, 27.40% and 0.55 mg). Additionally, with maternal care, female proportion of offspring, emergence ratio of coccon pupae and uncoccon pupae were 90.77%, 99.57% and 79.57%, respectively, which had no significant difference from those of the wasps without maternal care (87.96%, 97.74% and 84.45%, respectively). But, the emergence ratio of coccon pupae was over 13% higher than uncoccon pupae's.
