摘 要 ：作者对各种不同生境中蚜虫体色进行了观察,并通过胚胎解剖、染色体镜检研究了棉蚜体色规律性变化的原因。试验结果表明,棉蚜体色在世代内稳定不变;在世代间则随温度升高体色由绿渐变至黄。温度降低,体色又由黄渐渐转绿。统计检验证实:棉蚜体色变化与营养、寄主种类、光照光质、栽培条件等无关;仅与温度密切相联;性蚜体色与初产卵卵色均为绿色。木槿、花椒上的深黄色棉蚜,其体色不随温度改变,表明其已构成棉蚜体色变化的遗传多态现象。体色随温度变化的蚜虫在生态遗传学上属于基因型对环境条件的反应规范。

Abstract:The test results showed that the body colour is stable and unchangeable with in generation,namely,their life time is body colour just borr,whether they are natural or laboratory population and whether colony or individual feeding,and whether hosts,cultural condition or developmental nutrient to be the same or not.But the body colour change gradually from green to yellow with the temperature rising and from yellow to green with the temperature reducing in different generations.The Statistical test proved tha...
