在恒温（２７℃±１℃）、恒湿（７０±５）％ＲＨ条件下，研究了棉花、玉米、大豆、花生、芝麻５种寄主对棉铃虫生长、发育和繁殖的影响。结果表明，在不同寄主及其不同部位上取食的棉铃虫，其发育历期、蛹重、存活率、成虫的繁殖力和寿命均有显著差异；棉铃虫在玉米、大豆等作物上的密度较高，且不同作物上的幼虫发育参差不齐。作者认为，田间多种作物并存的局面是造成棉铃虫世代混杂、防治困难及猖獗危害的原因之一。
The effects of five hosts of cotton, corn, soybean, peanut and sesame on the growth, development and reproduction of cotton bollworm (Helicoverpa armigera) were studied under the condition of constant temperature of 27 ℃ ± 1 ℃ and constant humidity of 70 ± 5% RH. The results showed that the developmental duration, pupal weight, survival rate, adult fecundity and life span of H. armigera fed on different hosts and their different parts were significantly different. The bollworm’s density on crops such as corn and soybean Higher, and different crops larvae development is uneven. The author believes that the coexistence of a variety of crops in the field is one of the reasons for the generation of cotton bollworm from generation to generation, prevention and treatment of difficulties and rampant hazards.
