Abstract

To determine the effects of newly developed insecticide (Ultra) on Sycamore lace bug (Corythucha ciliata), ten leaf discs were sprayed with the Ultra solution including the other selected commercialized insecticide solutions such as Carbaryl and Pirimicarb, and also with a water-sprayed control. According to the results, the control effect of Ultra on the adults and immatures was respectively 98.9% and 97.5% after 48hr, and the corresponding values were higher than that of the other tested insecticides (i.e Carbaryl showed 84.6% for adults and 85.6% for immatures; Pirimicarb showed 83.0% for adults and 90.7% for immatures). For the Susceptibility test, LC$_{50}$ value of Ultra showed the lowest as 1.5ppm, the value of Carbaryl and Pirmicarb were 3.7 ppm and 30.4 ppm, respectively. Therefore, the insecticidal effects were better for the newly developed insecticide than the commercialized insecticides.

우리나라에서 발생하고 있는 버즘나무의 주요 해충인 버즘나무 방패벌레의 효과적인 방제를 위해 개발된 신규 합성물질과 기존 나무 해충 방제용 약제인 Carbaryl과 Pirimicarb의 방제효과를 검정하였다. 신규 합성물질의 48시간 경과 후의 방제율이 성충과 약충 각각 98.9%와 97.5%로서 기존 살충제인 Carbaryl의 84.6% 및 85.6%, Pirimicarb의 83.0% 및 90.7% 보다 높았으며, 실험 약제에 대한 감수성 조사 결과에서 신규 합성 물질의 LC$_{50}$값이 1.5 ppm으로 가장 낮아 역시 방제효과가 가장 좋은 것으로 조사되었으며, 다음이 Carbaryl이 3.7 ppm, Pirimicarb이 30.4 ppm순으로 살충효과를 나타내었다.
