摘要:

研究了低温贮存被丽蚜小蜂寄生的B型烟粉虱褐色伪蛹对丽蚜小蜂种群品质的影响。1~6日龄褐蛹于11℃贮存10d的结果表明,3日龄褐蛹中羽化的成蜂寿命、产卵量和刺吸量均优于其他日龄;在11℃下贮存10、20、30d后,上述生物学指标和种群参数均随贮存天数增加而明显降低,其中以10d的净生殖率、内禀增长率和周限增长率较未贮存的差异小。

Abstract:

The present paper investigated the effect of cold storage of the parasitized Bemisia tabaci pupae on the population quality of Encarsia formosa. The 1-6d old pupae were stored at 11℃ for 10d. Results showed adult wasps emerged from 3d old pupae had higher emergence rate, longer adult life, higher oviposition rate and higher host feeding ability than all the other pupae of different ages. The biological qualities decreased significantly as the period of cold storage increased from 10d to 20d and 30d.
