摘要: 台湾甲腹茧蜂Chelonus formosanus Sonan是多种鳞翅目害虫的重要寄生性天敌,对害虫的生物防治具有较大利用价值。为探明不同因子对台湾甲腹茧蜂交配率的影响,以提高其雌蜂的比例,从而提升室内扩繁效果,本试验研究了不同温度、营养、雌雄比、配对时间及空间大小对台湾甲腹茧蜂交配率的影响。结果表明,随着温度的升高,交配率逐渐上升,32℃最高为45.0%。不同营养对交配率的影响差异不显著。雌雄比为1♀:1♂时,交配率最低,仅为7.5%,当1♀:7♂时,交配率最高,为80.0%。随着配对时间的延长,交配率呈上升趋势,当配对时间为5 d时,交配率最高,为75.0%。随着空间的体积大小从348 cm3逐渐增大到1920 cm3,交配率逐渐下降,最低为5.0%。综上,最佳因子下台湾甲腹茧蜂交配率为97.5%。

Abstract: Chelonus formosanus Sonan is a dominant parasitoid of many lepidopteran pests and has great potential for utilization in the biological control of pests. The effects of different factors (temperatures, nutrition, sex ratios, dating time, and space size) on mating of C. formosanus were tested so as to improve efficiency of mass-rearing by increasing the female rate. The results showed that the mating rate increased gradually with the increase in temperature. The highest mating rate of 45.0% was achieved at 32℃. The mating rate was not significantly affected by nutrition. When the sex ratio was 1♀:1♂, the mating rate was the lowest, only 7.5%; the highest mating rate was 80.0% when the ratio was 1♀:7♂. The mating rate increased with the extension of dating time. The highest rate of 75.0% was obtained with the dating time of 5 days. As the volume of the space gradually increased from 348 cm3 to 1920 cm3, the mating rate decreased gradually, and the lowest was 5.0%. The optimal combination of factors was established and the highest mating rate of 97.5% was observed.
