摘要
采用A、B和C 3种饲料饲养沙棘木蠹蛾Holcocerushippophaecolus,A饲料成分为水、玉米粉、豆粉、蔗糖、琼脂、酵母粉、山梨酸钾、对羟基苯甲酸甲酯 ;B饲料成分为水、玉米粉、豆粉、琼脂、酵母粉、抗坏血酸、苯甲酸钠 ;C饲料成分为大豆粉、沙棘木粉、蔗糖、琼脂、维生素混合液、酵母浸粉、抗坏血酸、防腐剂混合液、无机盐。其中 ,B饲料防腐能力较差 ,饲养 1 2周后放弃。A和C 2种饲料能使沙棘木蠹蛾幼虫体重持续增长 ,饲养前期A饲料平均体重增量是C饲料的 1 6倍 ,A和C 2种饲料化蛹率分别为83. 3 %和 66. 7% ,羽化率分别为 3 0 % ,1. 6 7%。选择在沙土中结茧化蛹 ,能显著提高饲养成功率。
Three kinds of artificial diet, A, B and C were developed to rear Holcocerus hippophaecolus. Diet A contains water, maize powder, bean powder, cane sugar, agaragar, leaven, potassium sorbale, Methylp hydroxybenzoat. Diet B contains water, maize powder, bean powder, agaragar, leaven, VItamin-C, sodium benzoate. Diet C contains bean powder, seabukthorn powder,cane sugar,agaragar, leaven, VItamin-C, mixed antiseptic solution, inorganic salt. Because easily being stained, Diet B was given up after 12 weeks. The result shows that the weight of the larvae feeding on diet A and C can maintain increasing, and average increased weight of larvae feeding on diet A increases by 60% than that on diet C in early period of rearing. The pupation rate of A is 83.3%, C is 66.7%. The emergence rate of A is 30%, C is 16.7%. Pupating in sand soil plays important role during rearing process.
