众所周知,害虫群体可产生对杀虫剂的抗性。侵害棉花的棉铃虫复合体(Heliothis ssp.)就是这方面的一个极好例子,它是一种具有高度适应性的害虫。为了取得长远效果,培育杀虫作物(包括棉花)的遗传工程计划需要考虑害虫适应性交化的潜力问题。以棉铃虫复合体为模式,可以看出如何通过由遗传工程学家、进化生物学家和生态学家参加的对害虫 It is well-known that pest populations can develop resistance to pesticides. An excellent example of this is Heliothis ssp., A highly adaptive pest that infests cotton. In order to achieve long-term results, the genetic engineering program for the development of insecticidal crops (including cotton) requires consideration of the potential of pest adaptation. With the pattern of the H. armigera complex, one can see how the pests can be affected by the participation of geneticists, evolutionary biologists and ecologists
