三种幼虫外寄生蜂蛋白酶含量与离体培养饲料的关系

PROTEINASE CONTENT OF LARVAL ECTOPARASITOIDS AND ITS RELATION TO THE ARTIFICIAL DIET FOR IN VITRO REARING

在离体培养幼虫外寄生蜂过程中，发现不同的蜂对饲料中的蛋白质及游离氨基酸的含量有不同的要求，本文对麦蛾茧蜂（Ｂ．ｈｅｂｅｔｏｒ），矛茧蜂（Ｏ．Ｐｌａｌｉａｔｕｓ），管氏肿腿蜂（Ｓ．ｇｕａｎｉ）的蛋白酶活性，饲料中蛋白质及游离氨基酸含量进行了测定．实验表明：蛋白酶含量低的蜂，饲料中含高游离氨基酸及低蛋白；蛋白酶含量高的蜂，饲料中含低游离氨基酸及高蛋白。

Proteinase content of three larval ectoparasitoids were tested in this paper. The results indicate that proteinase content is directly proportional to protein content of diet, and inversely proportional to free amino acids content of diet.
