| 摘 要： | 就棉铃虫和烟青虫对寄主的选择和适应能力进行了研究。结果表明 :①烟青虫对食物的选择性比棉铃虫强 ,适应植物、获取营养的能力较弱 ,这可能是烟青虫的寄主范围较窄的原因之一②即使是昆虫的适食寄主 ,植物同样也能产生阻碍其消化和利用的化学物质

| Abstract: | The selection and adaptability of cotton bollworm Helicoverpa armigera and oriental tobacco budworm H assulta to host plants were studied. The results were as following:①The larvae of H assulta was higher selective to host plants than H armigera , but its adaptability to plants was lower. Maybe it was one of the reasons that H armigera had more extensive host range. ②Even if the plants were suitable to phytophagous insects, the biochemical defense mechanisms to the insects existed. |
