초록

고온 처리를 통한 화랑곡나방의 방제효과를 검토하기위하여 제분시설 공간을 $60^{\circ}C$ 이상으로 가온하여 3시간이상을 유지한 후 충태별 사망률(${\pm}$표준오차)을 조사하였다. 가열 처리 후 시설 공간내의 온도는 위치에 따라 차이를 보여 $60^{\circ}C$ 이상이 유지된 시간이 주변부에서는 3시간, 중앙부에서는 11시간이었다. 화랑곡나방의 고온에 대한 내성은 충태에 따라 유의한 차이가 있었다. 성충의 경우 가장 작아 처리 위치에 관계없이 $100\%$의 사망률을 보였고, 알이 가장커서 위치에 따라 $91.40{\pm}0.93{\sim}98.80{\pm}0.20\%$를 보였다. 유충의 사망률은 $96.00{\pm}0.67{\sim}100\%$의 범위에 있었다. $60^{\circ}C$ 이상의 온도가 11시간 이상 유지된 위치에서도 알의 사망률은 $100\%$에 이르지 않아 보다 장시간의 처리가 필요함을 보여주었다. 이를 토대로 소규모 제분시설에서의 가열방제에 대해 간략히 논의하였다.

In a flour milling facility, control ability of superheating effect on Indian meal moth population was teated. Thirty adults, thirty larvae and 100 eggs were placed in a paper bag ($10{\times}20cm$) containing 100 g flour and were exposed to the temperature higher than $60^{\circ}C$ for longer than 3 hours. Mortality of the Indian meal moth (${\pm}standard error$) varied with the developmental stage; mortality (${\pm}standard error$) of egg, larvae and adult were in the range of $91.40{\pm}0.93{\sim}98.80{\pm}0.20\%,\;96.00{\pm}0.67{\sim}100\%$) and $100\%$, respectively. The position of paper bag caused differences in temperature and its exposure time to the moth during the experiment, consequently. The mortality of moth was significantly different among the bag position. Exposure of the paper bag to the temperature of higher than $60^{\circ}C$ for longer than 11 hours was not sufficient to kill all the eggs.
