野桑蚕和家蚕的环境适应性比较研究

野桑蚕和家蚕对不同组分人工饲料的食性比较研究表明 ,野桑蚕不取食无桑叶粉的人工饲料 ,4 8h不出现疏毛现象 ,其食性较家蚕单一。以完成虫态的积温研究二者对气象环境的适应性 ,发现野桑蚕对气象环境的适应性较家蚕强 ,野桑蚕完成不同虫态所需的有效积温较稳定。对野桑蚕和家蚕添食农药和紫外辐照处理 ,结果表明野桑蚕对不良的环境的耐受性较家蚕强 :添食相同浓度的农药 ,家蚕全部中毒死亡 ,而野桑蚕却部分存活 ,且正常化蛹 ;紫外线辐照可使野桑蚕提前老熟营茧

Adaptability Comparison of the Bombyx mandarina Moore and Bombyx mori L.to the Environment

Through the comparison of feeding habit for artificial diet of different ingredients between Bombyx mandarina Moore and Bombyx mori L. the results showed that the larvae of Bombyx mandarina Moore didn't take the artificial diet without mulberry leaf powder and show statae dispersion within 48 hours,the feeding habit of Bombyx mandarina Moore was unitary; that Bombyx mandarina Moore had better adaptability than Bombyx mori L. through research on the accamulated temperature to compare their adaptability for different climatic factors and the accamulated temperature for the Bombyx mandarina Moore to complete various stage is more stable.Through ultraviolet irradiation and pesticide feeding test,that is,affer administration of same concentration of pesticide to the larvae,all the Bombyx mori died while some of Bombyx mandarina Moore survived and completed pupation normally,and the ultraviolet irradiation advanced maturation of the Bombyx mori Moore,the results of which showed that Bomhyx mandarina Moore's endurance to bad factors was better than Bombyx mori.
