초록

Matsucoccus matsumurae is the main forest insect pest of the Pinus thunbergii and Pinus densiflora in South Korea. In this experiment, we had verified the insecticidal effects of Amitraz, deltamethrin and sulfoxaflor, using ground spraying since the trunk injection has not been greatly effective for the control recently. We divided the methods for three ways to confirm the insecticidal effects by developmental stages. Firstly, in male, only amitraz among the insecticides showed significant mortality. Secondly, in female, none of the treatments showed significant mortality but showed delay synthesize the wax filaments when the amitraz treated. In addition, sulfoxaflor treatment showed significant lower egg production rate. Lastly, in 2nd nymph, all insecticides were not shown insecticidal effect. Above the results shown that the ground spraying of three insecticides for M. matsumurae was not a proper control method.
