随着激素、引诱、不育等防治新技术和抗性、毒理等研究工作的进展,棉红铃虫Pectino-phora gossypiella(Saunders)人工饲养技术急需研究改进。本文根据陆伊文等介绍的化了饲养程序。改进后的饲料配方使幼虫成活率稳定在81％以上(原配方成活率30-65％)。幼虫历期15.7±2.1天比原配方30.21±9.31天缩短14天,而且发育整齐。蛹重16.4毫克比原配方13.03毫克/头增加30％以上。此幼虫历期和蛹重介于自然食铃、食蕾幼虫发育历期和蛹重之间,已为抗虫鉴定、抗药性测定等试验提供了成批材料。
With the advances in new technologies for controlling and resistance to hormones, attractants and infertility, and resistance and toxicology, artificial feeding techniques for Pectino-phora gossypiella (Saunders) need to be improved. This article according to Lu Yiwen introduction of the breeding program. The improved feed formula larvae survival rate of more than 81% (original formula survival rate of 30-65%). The larvae duration of 15.7 ± 2.1 days shorter than the original formula 30.21 ± 9.31 days 14 days, and the development of neat. Pupa weight 16.4 mg 13.03 mg / head than the original formula increased by 30%. The larval duration and pupal weight between the natural food bell, the development period of food bud larvae and pupal weight, has been insect-resistant identification, drug resistance test provides a batch of materials.
