棉花、小麦、玉米和大豆是我国北方棉区棉铃虫的4种主要寄主植物。作者研究了在恒温条件下取食上述4种寄主植物的生殖器官对棉铃虫发育与繁殖的影响,并通过分析生殖器官的化学成分,探讨了造成不同影响的原因。 1 材料与方法 1.1 供试虫源:为本所用人工饲料连续饲养多代的棉铃虫。
Cotton, wheat, corn and soybean are the four main host plants of cotton bollworm in northern cotton area of China. The author studied the effects of genital organs feeding on the development and reproduction of cotton bollworm (Helicoverpa armigera) on the four host plants under constant temperature, and analyzed the causes of the different effects by analyzing the chemical composition of reproductive organs. 1 Materials and methods 1.1 for test insect source: based on the artificial feed used for breeding multiple generations of cotton bollworm.
