用双层石蜡膜 ( Parafilm‘M’)夹营养液的方法饲养麦长管蚜。经系统分析小麦植株的营养成分和反复实验 ,确定麦蚜全纯人工饲料配方 ,营养液的适宜 p H值为 6.0 ,适宜糖浓度为 2 5%。对所选的基础饲料配方的氨基酸和维生素单一缺失实验结果表明 ,麦长管蚜必需的营养物质中包括 9种氨基酸和 8种维生素 ,非必需营养组分包括 6种氨基酸及泛酸钙和肌醇等 2种维生素 ,此外 7种氨基酸以及核黄素为非营养组分或有害组分。通过全部剔除非营养组分后得到的纯人工饲料饲养的结果表明 ,麦长管蚜饲养的结果很好 ,其存活率及繁殖力与感蚜麦苗上的差异不显著 ,而且可连续饲养 2代。
Aphis gossypii was fed with a parafilm ’M’ nutrient solution. The systematic analysis of wheat plant nutrients and repeated experiments to determine the wheat aphid hologenic feed formula, nutrient solution p H value of 6.0, the appropriate sugar concentration of 25%. The results of single amino acid and vitamin deletion experiments on the selected basic feed formulation showed that the essential nutrients of A. avenae included 9 kinds of amino acids and 8 kinds of vitamins and the non-essential nutrients including 6 kinds of amino acids and calcium pantothenate and inositol And other two kinds of vitamins, in addition to seven kinds of amino acids and riboflavin non-nutritive components or harmful components. The result of pure artificial diet obtained by completely eliminating non-nutritive components showed that the results showed that the results showed that there was no significant difference in the survival rate and fecundity between the two groups, .
