摘要：为筛选出防治栗山天牛Massicus raddei（Blessig)成虫的不育剂，本研究利用灭幼脲Ⅲ号、除虫脲和杀铃脲3种仿生制剂分别稀释500倍、1000倍、1500倍、2000倍、3000倍和4000倍等6种浓度进行处理，对其成虫进行了不育性试验。结果表明，这3种不育剂不同处理在雌雄虫寿命、产卵量和产卵期、子代卵的孵化历期的差异均不显著，但经不育剂处理过的雌虫后期产卵量要明显小于对照；不同处理间子代卵的孵化率差异显著，特别是3种药剂500倍液处理后的孵化率分别为19.07%、23.74%和26.3%，远低于对照组的90.21%。三种不育剂1500倍以上的稀释浓度对卵的孵化均有明显的抑制作用，孵化抑制率与浓度之间呈正相关关系，其毒力方程均达到了极显著水平，其中灭幼脲Ⅲ号比其它两种不育剂效果更好。

Abstract: For selecting a bionical chemosterilant to control adults of the oak longhorn beetle, Massicus raddei (Coleoptera: Cerambycidae), a study on sterilized impacts of three bionical chemosterilants, i. e., chlorbenzuron, diflubenzuron and triflumuron, were carried out. They were diluted to six different concentrations, i. e., 500, 1000, 1500, 2000, 3000 and 4000 times as six treatments. The results showed that there were no significant differences among the three chemosterilants in female and male adult life-span, number of eggs-laying, the lasting time both of egg-laying and egg hatching. However, the egg numbers laid were much lower than the control group. Meanwhile, the egg-hatching rate indicated significantly different among the different treatments, and particularly the treatments of three chemosterilants with 500-times dilution showed good results: the egg-hatching rates were 19.07%, 23.74% and 26.3% respectively, comparing with the control group 90.21%. The concentrations of three chemosterilants with 1500-times dilution all revealed significant inhibitive impacts on egg hatching, and the inhibition correlated positively with concentration. The toxicity equations were significant, and the inhibitive impact on egg hatching by chlorbenzuron showed the highest.
