ウヅキコモリグモ幼体の殺虫剤感受性

The effects of several pesticides on the survival of spiderlings of Pardosa astrigera L. Koch, which is regarded as a promising natural enemy against the diamondback moth in cabbage fields, were examined using a spraying tower in the laboratory. Most organophosphates, pyrethroids and carbamates were determined to be highly toxic to the spiderlings, but 11 insecticides (Chlorfluazuron, Teflubenzuron, Lufenuron, Flufenoxuron, Chromafenozide, three BT-insecticides, Pyridalyl, Thiamethoxiam, Indoxacarb) were harmless or very weakly toxic. The use of insecticides that are less toxic to spiderlings should be recommended in IPM programs to control cabbage pests.
