이화명나방(Chilo suppressalis Walker)의 합성 성pheromone((Z)-11-hexadecenal＋(Z)-13-octadecnal)을 이용한 이화명충 방제효과를 구명하고저 야외에서 시험한 결과 Microencapsulation된 pheromone을 trap 주위에 30mg을 산포할 경우 처리 7~10일 후까지 성충 교미교란, 효과가 있었으며 Hexane으로 희석한 pheromone 용액을 polyethylene vial에 넣어 유인 trap 주위에 둥글게 배치할 경우 처리 20일후 까지도 교미교란 효과가 있었다.
Double microencapsulated sex pheromone formulation for the striped rice borer, Chilo suppressalis, was used at the doses of 10 and 30mg per trap with 100$mu extrm{g}$ attractant sources. The dose of 30mg was found to be effective in completely disrupting male orientation for ca. 7~10 days under the field conditions. Mating disruption induced by the application of 10mg during the same period after treatment was reduced by ca. 9~22%, compared with that of 30mg. Polyethylene vial was found to be very steady and efficient releaser of pheromone, giving male orientation disruption for at least 20 days in the case of 30mg.
