不同食料对苹果蠹蛾生长发育和繁殖的影响

在室内研究了红玉苹果、红元帅苹果、张掖2号苹果、沙果、苹果梨、早酥梨、杏对苹果蠹蛾［Cydia pomonella (L.)］生长发育和繁殖的影响。结果表明,不同食料对苹果蠹蛾幼虫和蛹的发育历期、存活率、蛹重、雌成虫寿命、雌成虫产卵量等有显著影响。幼虫取食沙果、早酥梨、红玉苹果最有利于其生长发育和繁殖；取食红元帅苹果和张掖2号苹果的影响居中；而取食杏和苹果梨对其生长发育和繁殖表现出明显的不利性，主要表现为幼虫死亡率增加，幼虫期延长，蛹期延长，蛹重减轻，雌成虫寿命缩短，单雌产卵量降低。

Effects of different foods on growth, development and reproduction of the codling moth, Cydia pomonella

The effects of seven food plants (Jonathan apple, red delicious apple, Zhangye number two apple, Chinese pear leaved crab apple, applepear, crisp pear, apricot) on the development and reproduction of the codling moth were studied under laboratory temperature. The results showed that there were significant differences in developmental duration of larvae and pupae, survival rate, pupal weight and numbers of the eggs laid per female of the codling moth feeding on different host plants. The most favorable food in the seven host plants for the growth, development and reproduction of the codling moth were Chinese pear leaved crab apple, crisp pear, Jonathan apple, followed by the red delicious apple and Zhangye number two apple. When the larvae were fed with apricot and apple pear, the death rate of the larvae increased, and the larval and pupal stages prolonged, but the pupal weight decreased, female adult life shortened and the average fecundity reduced．
