弹尾目昆虫对重金属污染的反应，不同的种之间有很大的差别，其中，裸长角属对Cu污染反应不灵敏，陷等属、棘属对Cu污染反应敏感，随着污染程度的加剧，它们的数量明显减少；小等属和长属对Cu、Zn、Cd、Pb等重金属元素的复合污染反应很敏感，而裔符属、球圆属、土属、圆属和鳞长属对重金属复合污染反应很迟钝，在这些重金属复合污染严重的农田中仍能很好地生存繁衍。

A total of 19,781 insect individuals belonging to 959 morphospecies, 145 families and 15 orders were collected. The most abundant orders were Diptera (69.68%), Homoptera (11.19%) and Hymenoptera (10.10%). At the family level, Chironomidae (17.67%), Mycetophilidae (12.32%), Cicadellidae (8.32%), Ceratopogonidae (7.56%), Sciaridae (7.39%) and Cecidomyiidae (5.81%) were the most abundant taxa. Although there were little differences in similarity among the three sampling plots, the dominant orders and families in theses plots differed. The meadow had the highest diversity while the spruce forest had the lowest diversity.

结果：三样区共采集到19，781只昆虫，分属15目、145科、959个形态种；各目的组成百分比，以双翅目(69.68%)、同翅目(11.19%)及膜翅目(10.10%)最为优势；在科的类阶，则是以摇蚊科(17.67%)、蕈蚋科(12.32%)、叶蝉科(8.32%)、糠蚊科(7.56%)、黑翅蕈蚋科(7.39%)及瘿蚋科(5.81%)为优势类群；三个样区的相似度差异不大，但是优势类群则不相同；无论丰度、均匀度及多样性指标，箭竹草原样区均高过於云杉林样区及铁杉林样区。

Food compositions of M. albus were investigated in areas of three counties in Hubei province. Diets of the M. albus with body length less than 100mm change with their growth: from Rotifera and Cladocera to Oligochaeta and Chironomidae.

通过对不同产地的271尾野生黄鳝的食性的研究表明，全长小于100mm的稚鱼，其食性随着全长的生长而变化，稚鱼前期以摄食轮虫、枝角类为主，后期以水生寡毛类、摇蚊幼虫为主。

However, the food composition of the M. albus with body length more than 100mm were quite consistent, with Chironomidae, Oligochaeta, Pheretima, Cladocera, Copepoda and insect larvae as the major food items.

而全长101-200mm的幼鳝及全长大于200mm的成鳝的食性，随全长变化相对稳定，且幼鳝和成鳝的食谱基本相同，其主要食物组成均包括摇蚊幼虫、水生寡毛、蚯蚓、昆虫幼虫、枝角类和桡足类等。
