摘  要:
通过设计一套试验装置,研究了蚯蚓对土壤中杀虫剂的回避行为。结果显示,蚯蚓对某些杀虫剂非常敏感,土壤中杀虫剂含量达到其半致死浓度(LC50)的1/5~1/25时,即出现明显的逃逸或迁移行为。

摘  要:
Due to the fact that appulsion of favorable conditions and repellence of adverse surroundings are regarded as an instinct for living organisms, a determining instrument for evaluating behavior of earthworm was designed in order to study the excluding behavior of earthworm against pesticides in soil. The results showed that earthworm (Eisenia foetida) is very sensitive to some pesticides in the soil tested, the escaping behavior of earthworm can be examined in the soil tested at very low concentrations, from 1/5 to 1/25 of the LC50 values, of pesticides. Therefore, it may be suggested that the test instrument be used as a diagnosis method for soil health quality.
