摘要
采用单管饲养法,研究了不同营养源对细点扁股小蜂成虫寿命和产卵量的影响。结果表明:葡萄糖、蔗糖、蜂蜜饲养的雌蜂和雄蜂寿命差异显著(P<0.05),而花粉、清水和对照饲养的雌蜂和雄蜂寿命差异不显著;补充蜂蜜、葡萄糖、蔗糖等营养均能显著延长细点扁股小蜂的寿命,与补充花粉、清水处理相比,平均寿命延长了3～9倍;20%蜂蜜饲养效果显著高于其他浓度,雌蜂寿命达到(35.2±1.1)d,较无饲喂处理寿命延长14倍以上;产卵量方面,10%和15%葡萄糖饲养效果显著高于其他浓度,雌蜂产卵量分别达到(67.5±3.4)粒和(65.6±2.7)粒,是清水饲喂处理的10倍以上。该研究结果可以为细点扁股小蜂的大量繁殖提供参考。
Single-tube feeding method was used to investigate the effects of different nutritive materials on the lon- gevity and fecundity of Elasmus punctulatus. The results showed that there was significant difference between the longevity of E. punctulatus males and females fed by glucose, sugar and honey respectively （P〈0.05）, while there was no significant differences in the longevity between E. punctuIatus males and females fed by pollen, water and the control. Honey, glucose and sugar could significantly prolong the longevity of E. punctulatus. Compared to the treatment by pollen and water, the average longevity of E. punctulatus fed by honey, glucose and sugar was extended by 3-9 times. The 20% honey had significantly higher effects than other concentrations, and the longevity of female E. punctulatus was （35.2±1.1）d, 14 times over the non-feeding treatment. In terms of fecundity, the 10% and 15% glucose had significantly higher effects than other concentrations, and the fecundity of female E. punctulatus was 67.5±3.4 and 65.6±2.7, respectively, 10 times over the water-feeding treatment. These results could provide a reference for E. punctulatus multi-breeding.
