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.

本文从龟纹瓢虫的生物学和生态学特性，包括色斑变型、生活史、繁殖、食性、越冬、人工饲养、田间动态以及在生物防治上的应用等方面概述了龟纹瓢虫的研究进展，提出进一步深入开展龟纹瓢虫的人工饲养技术、贮藏技术和色斑变型遗传机制等的研究，不仅可以更好地为农业生产服务，而且可以充实昆虫生态位理论的研究内容。

Prolactin receptorgene was studied as a candidate gene for the prolificacy of Jining Grey goats. Eight pairs of primers were designed to detect single nucleotide polymorphisms of exon 3 to exon 9 and intron 9 of PRLR gene in both high fecundity breed and low fecundity breeds (Liaoning Cashmere goat and Angora goat) by PCR-SSCP.
