摘要
本试验研究低温状态下半闭弯尾姬蜂蛹重波动规律。结果表明,半闭弯尾姬蜂雌、雄蜂在低温下存在2种不同发育生理型态,分别是发育蛹和不发育蛹,其蛹的减重幅度均高于对照的正常发育蛹。在10℃低温下,不发育蛹的重量降低过程较缓慢,而常温对照或低温下发育蜂蛹重量降速较快。低温不发育蛹在低温贮存期间,其重量减轻曲线平缓。在10℃低温下,寄生蜂羽化率低于常温,雌蜂羽化率仅为33%,雄蜂羽化率达70%。研究表明,半闭弯尾姬蜂不发育蛹通过维持较低的代谢水平来渡过低温环境,蛹具有一定的生态适应性。
This research measured weight changes of Diadegma semiclausum pupae at low temperature storage. Under low temperature, there were two kinds of developmental types in the pupae： development and undevelopment. The pupae lost weight at low temperature as compared with those at normal temperature. Under 10 ℃, weight loss in the undeveloping pupae was relatively slower than that in the developing pupae and the control pupae. Emergence rate was lower at 10℃than at normal temperature, being 33%for female pupae and 70%for male pupae. Our results show that the undeveloping pupae survive low temperature by maintaining low metabolism rate, exhibiting a certain ecological adaptability.
