摘  要：
【目的】研究药剂对棉铃虫繁育能力的影响,为安全有效的控制棉铃虫危害奠定理论基础。【方法】采用饲喂法处理棉铃虫成虫,对其产卵量、卵孵化率、实验前后成虫体重差、成虫寿命进行测定。【结果】甲氨蝶呤抑制棉铃虫产卵量效果优于紫杉醇,0.02%甲氨蝶呤处理的棉铃虫单雌产卵量(104粒)最低,比对照降低了72.48%;紫杉醇抑制卵孵化效果好于甲氨蝶呤,0.5%紫杉醇处理的卵孵化率为11.43%,平均校正不育卵率(89.19%)达到最高。甲氨蝶呤处理对雌虫的寿命比对照缩短1～2 d。紫杉醇对棉铃虫雄虫有增重作用,而甲氨蝶呤对棉铃虫雌虫有减重作用。【结论】甲氨蝶呤和紫杉醇对棉铃虫繁育能力均有弱化作用,0.02%甲氨蝶呤弱化棉铃虫单雌产卵量效果最好,0.5%紫杉醇抑制卵孵化效果最佳。

摘  要：
【Objective】 The purpose of this study was to investigate the effects of agentia on the ability of breeding of cotton bollworm,Helicoverpa armigera(Hübner) in order to lay foundation of controlling the harm of cotton bollworm safely and effectively.【Method】Feeding treatment with Methotrexate and Paclitaxel was used to determine the number of eggs laid by per female moth,hatching rate,body weight and lifetime of the adult.【Result】The inhibition effect of Methotrexate for laying eggs of cotton bollworm was better than Paclitaxel indoor environment.The number(104 head)of eggs laid by per female moth was the lowest after the treatment using 0.02% Methotrexate,72.48% reduced than CK,while the inhibition effect of Paclitaxel for hatching rate of eggs was better than Methotrexate.The rate of hatching rate of eggs was 11.43% treated by using 0.5% Paclitaxel,and the revised sterility eggs rates(89.19%)was the highest.Lifetime of adult moth was reduced by 1 to 2 days in female moths with Methotrexate treatment.Paclitaxel had the function of increasing weight of the male,but Methotrexate could reduce female's weight.【Conclusion】 Both Methotrexate and Paclitaxel could attenuate the ability of breeding of cotton bollworm,the effect of 0.02% Methotrexate was the best for the purpose,and 0.5% Paclitaxel was best for controlling the rage of hatching eggs than other chemicals.
