查询词典 pear

When the larvae were fed with Apricot and apple-pear the death rate of the larvae increased,the larval and pupa stages prolonged, the pupa weight decreased, female adult life shortened and the average fecundity.The age-specific life table of codling moth indicated that the trend index of codling moth population fed on Jonathan apple, Red Delicious apple, Zhangye number two apple, Chinese pear-leaved crab-apple and Crisp pear were more than one. Experiment population quantity was at the growth condition. The trend index of codling moth population fed on Apple-pear and Apricot were less than one.
