摘要
希氏栉水虱（AsellushilgendorfiiBovalius，1886）分布于浙江德清、富阳、杭州等地的淡水中；在杭州主要生活在玉泉、黄龙洞、葛岭等处的溪流的底层泥表上，营底栖生活．野外种群的数量高峰出现在3月份，雄性达2080个／m2，雌性达1540个／m2．至春末初夏两性个体数量降至最低，9月之后数量回升．雌性生物量高于雄性，高峰期雌、雄性生物量分别为7234mg／m2、5729mg／m2．雌体年平均怀卵量为19．7粒，最高怀卵量出现在冬季，平均为26．3粒．幼体以“胎生”方式产生．成体在15．7℃培养下的个体增长量高于22．0℃．同胎幼体在不同温度培养下的增长量略有不同．该文还测定了木虱的呼吸强度和各种氨基酸的含量．
The biology and ecology of Asllus hilgendorfii living Yuqiu river of Hangzhou were studied. The field population of Asellus hilgendorfii are the greatest in number in spring (March), the male is 2080ind/m2,the female is 1540ind/m2. The average amount of egg production yearly are 26. 3ind. We found that the isopoda can breed throughout the year except the hottest month,July. The laboratory Population were tested at two temperatures: 15. 7℃ and 22. 0℃. At the same time, we also have anal- ysed the chemical component and amino acid of the isopoda. There are sixteen kinds of amino acid in the body of Asellus hilgendorfii
