Abstract
The thirteen commercial insecticides to Lycoriella mali were investigated on their insecticidal activities and mycelial growth of two Letinula edodes strains. For the adults, insecticides showing over 95% insecticidal activity were chlorpyrifos-methyl, fenthion, fenitrothion, benfuracarb, furathiocarb and deltamethrin. For tile larvae, diflubenzuron and cyromazine showed over 90% insecticidal activity. Fenthion, benfuracarb, furathiocarb, deltamethrin, diflubenzuron and cyromazine did not affect the mycelial growth of L. edodes strain, in Imhyup 1 variety. And deltamethrin, diflubenzuron and cyromazine did not affect that in Sanlim-5. Insecticides showing over 80% residual effect for 14 days were benfuracarb to the adults and diflubenzuron and cyromazine to the larvae. Control effect of furathiocarb, fenthion, benfuracarb, deltamethrin, diflubenzuron and cyromazine against larvae of Lycoriella mali showed 90% ten days after application under sawdust cultivation. Among them, benfuracarb, fenthion and furathiocarb revealed excellent control effect against adults. These results indicate that benfuracarb, fenthion, and furathiocarb can be used for the control of Lycoriella mali in the field. However, further studies are needed on the effect of insecticides treatment oil fruit-body yield and chemical residue in the mushroom tissues.
본 연구에서는 표고 톱밥재배시 문제해충인 긴수염버섯파리 (Lycoriella mali)에 대하여 시판중인 13종 살충제의 약효, 잔효성, 균사생장억제율 및 방제효과를 평가하였다. 긴수염버섯파리 성충에 대해서 chlorpyrifos-methyl, fenthion, fenitrothion, benfuracarb, furathiocarb, deltamethrin이, 유충에 대해서 diflubenzuron과 cyromazine이 90%이상의 살충력을 나타내었다. 표고균사의 생장에 영향이 적었던 약제로는 임협1호에 대해서 benfuracarb, fenthion, furathiocarb, deltamethrin, cyromazine, diflubenzuron이, 산림5호에 대해서는 deltamethrin, cyromazine, diflubenzuron이었다. 특히 산림 5호는 임협 1호에 비하여 살충제에 대한 감수성이 높았다. 잔효성 시험결과 성충에 대해서 benfuracarb, 유충에 대해서는 cyromazine과 diflubenzuron이 14일째까지 80%이상의 잔효성을 나타내었다. befuracarb, fenthion, furathiocarb, deltamethrin, cyromazine, diflubenzuron은 유충에 대해서, benfuracarb, fenthion, furathiocarb는 성충에 대해서 80%이상의 방제가를 나타내었다. 이상의 결과에서 버섯내 농약잔류가 문제되지 않는다면 benfuracarb, fenthion, furathiocarb는 긴수염버섯파리 방제에 이용될 수 있을 것으로 생각된다.
