摘要: 为了提高花绒寄甲(Dastarcus hellophoroides Fairmaire)对核桃云斑天牛的防治效果,采用云斑天牛(Batocera horsfieldi)寄主植物核桃叶对花绒寄甲替代寄主黄粉虫(Tenebrio molitor)进行人工饲养,通过测定黄粉虫幼虫生长量及消化酶活性评价核桃叶作为饲料的适宜性。结果表明,核桃叶饲料对黄粉虫幼虫体内消化酶活性和生长状况有明显影响。麦麸饲料中添加未经发酵的核桃叶会抑制黄粉虫幼虫生长,而添加发酵的核桃叶黄粉虫幼虫则呈现增长的趋势,生长速度以50%麦麸+50%发酵核桃叶处理最快。不同饲料饲养的黄粉虫幼虫生长量与其体内蛋白酶活性呈正相关关系,与淀粉酶和蔗糖酶活性无相关性。

Abstract: In order to enhance the effect of Dastarcus helophoroides on prophylaxis and treatment of walnut Batocera horsfieldi,used walnut leaf,which is host plant of B. horsfieldi,to artificially feed Tenebrio molitor larvae that substitutes original host D. helophoroides,the suitability of walnut leaf as fodder through the determination of growth of T. molitor larvae was evaluated. The results indicated that walnut leaf fodder had obvious effects on digestive enzyme activity in T. molitor larvae and growth condition. Adding unfermented walnut leaf to wheat bran fodder can inhibit the growth of T. molitor larvae. Instead,wheat bran fodder with fermented walnut leaf showed increasing trend of T. molitor larvae,of whom the growing speed was fastest under treatment 50% wheat bran plus 50% fermented walnut leaf. Growing amount of T. molitor larvae was correlated with internal protease activity,but no correlation with amylase and saccharase activity.
