솔수염하늘소(Monochamus alternatus)에 대한 수종 살충제의 살충효과 = Toxic Effects of Some Insecticides on the Japanese Pine Sawyer, Monochamus alternatus

다국어 초록 (Multilingual Abstract)

To develop efficient control program against Japanese pine sawyer (JPS). Monochamus alternatus Hope, laboratory bioassay using 7 insecticides, and the residual effects of fog-machine treatment and ultra-low-volume spray by helicopter of fenitrothion induced 100% mortality 4 days after exposure (DAE), and exposure for 4 minutes did that 2 DAE. Even the periods when they were alive, they did not feed on treated P. densiflora shoots. All the topical applications of the fenitrothion on elytra, head, mouth, tarsus, and ventral parts show 100% mortality. The residual effect of fog-machine treatment of fenitrothion was very effective against JPS adults. When the adults were inoculated on the treated shoots at the 1st day of treatment with 50,000 and 5,000 ppm solution of fenitrothion, the LT_(100) was only 1 day; even at the 11th day it was only 3 days. The residual efficacy of ultra-low-volume spray with helicopter lasted longer than that of fog-machine treatment. When the JPS adults were inoculated on the sprayed shoots even at the 10th day of the spray with 60,240, 5,000 and 1,000 ppm, the LT_(100) was only a day.
