THE EFFECTS OF SUBLETHAL DIMETHOATE EXPOSURE ON THE LOCOMOTOR BEHAVIOR OF THE COLLEMBOLAN FOLSOMIA CANDIDA (ISOTOMIDAE)

摘要

The locomotor behavior of the collembolan Folsomia Candida Willem 1902 (Isotomidae) was automatically quantified during exposure to soil treated with sublethal concentrations of dimethoate. During the 36 h of measurement, significant changes were seen in walked distance, mean velocity, and turning rate. It is concluded that these end points provide a sensitive measure of toxic stress.
