研究了麻醉、低温处理黄粉虫蛹对繁育管氏肿腿蜂的影响。肿腿蜂寄生率、产卵量、出蜂量等随麻醉时间的增加而减少;在-4℃贮存1,5,10,20,30,45,60 d后,上述各项生物学指标以20 d和30 d为最优;在4,0,-4,-8℃分别低温贮存20 d后接蜂,生物学指标以-4℃最高。
The effects of anesthesia and low temperature treatment of Tenebrio pupae on the breeding of Schistosoma pallidipes were studied. The parasitic rate, fecundity and the amount of bee-eaters decreased with the increase of anesthetic time. After being stored at -4 ℃ for 1, 5, 10, 20, 30, 45 and 60 d, the above biological indexes 20 d and 30 d were the best. After being stored at 4, 0, -4 and -8 ℃ for 20 d, the bees were exposed to the highest temperature of -4 ℃.
