研究 4种食物对真水狼蛛发育和繁殖的影响。结果表明 :单喂果蝇时 ,幼蛛世代存活率最低 ;喂混合食物时幼蛛历期最短 ;单喂果蝇时 ,历期最长。幼蛛腹部体色与所喂食物颜色相近。喂混合食物的幼蛛 ,其背甲宽度和体重均大于其他 3种食物。雌蛛所产卵袋数和产卵总量均以喂混合食物时为最高。多种食物混合喂养 ,有利于真水狼蛛的个体发育和繁殖 The effects of four kinds of food on the development and reproduction of P. wolfii were studied. The results showed that when the flies were fed alone, the survival rate of the juvenile spider was the lowest; the spider larvae had the shortest duration when mixed with food; the longest duration was when the flies were fed alone. Juvenile abdominal body color and feeding color similar. Young spider fed mixed food, the carapace width and weight were greater than the other three kinds of food. The number of eggs laid by spiders and the total number of eggs laid were the highest when mixed with food. A variety of food mixed feeding, is conducive to the water body spider tarantula development and reproduction
