| 摘 要： | 研究两种食物及混合食物对草间钻头蛛生长发育及耐药性的影响．结果表明草间钻头蛛幼蛛在喂混合食物时，其成活率最高，5个龄期发育历期总和最短，二龄幼蛛历期比单喂果蝇和摇蚊的明显缩短．在喂混合食物时，雌蛛繁殖力最强，产卵袋数、卵粒数、单雌产卵量最高；同时，成蛛对杀虫剂氰戊菊酯耐药力最强．

| Abstract: | Studied the effect of three diets Drosophila melanogaster. or Tendipes. sp and mixed food (Drosophila melanogaster and Tendipes .sp) on the fecundity and resistance to Hylyphantes graminicola . The results showed that when spiderlings were fed on mixed food, their survival rate was the highest while the instars was the shortest; The duration of second instar was significantly shorter than that only fed on Drosophila melanogaster or Tendipes . sp; When fed on mixed food, the fecundity of female spiders was the strongest , the total number of the egg sac, the total number of the egg in each egg sac and eggs laid by the female spiders were the highest . At the same time, the resistance of spiders fed on mixed food to fenvalerate was the strongest. |
