Abstract

Economic injury levels and economic thresholds were estimated for the american serpentine leafminer (Liriomyza trifolii) on greenhouse eggplant. Liriomyza trifolii density was increased until the late June and decreased after the July in innoculation on may 17. Growth of an aerial plants and fruits were not different in treatment respectively. But total number of fruits and yields were decreased on higher inoculation density. Whereas the rate of yield loss was increased. The rates of damaged leaf by L. trifolii were increased on higher inoculation density and the peak was 65%. The number of commodity fruits and the rates of commodity fruit were become lower than non-treatment (72.2%). The rates of damaged leaf area were 5.3, 11.7, 19.7, 25.7% on inoculation densities and the rates of yield loss were 0.6, 4.8, 9.8, 14.7%, respectively. There existed close correlation between rate of yield loss and inoculation density (Y = 0.76779X + 0.298354, $R^2\;=\;0.9599$). Considerated of the results, the economic injury levels of L. trifolii on eggplant greenhouse was 6.1 adults per 4 plant and the economic thresholds was 4.9 adults per 4 plant.

시설 가지에서 아메리카잎굴파리 경제적피해수준 및 요방제수준을 추정하였다. 생육초기 아메리카잎굴파리 접종밀도에 따른 시기별 발생밀도는 5월 17일 접종 후 6월 하순까지는 계속 증가하다가 7월 이후 감소하는 경향이었다. 접종밀도별 지상부 생장 및 과실 생육은 유의한 영향은 없었으나, 총과수 및 수량은 접종밀도가 높을수록 감소하는 경향이었고, 그에 따른 수량감소율은 높아졌다. 피해엽율은 접종밀도가 높을수록 증가하여 20마리/4주 수준에서 65%의 피해가 나타났으며, 상품과수 및 상품과율은 무접종구(12.2%)에 비해 접종밀도가 높을수록 감소하였다. 아메리카잎굴파리 접종밀도에 따른 피해 엽면적비율은 각각 5.3, 11.7, 19.7, 25.7%였고, 이때 수량감소율은 각각 0.6, 4.8, 9.8, 14.7%를 나타내었다. 아메리카잎굴파리 접종밀도(X)와 수량감소율(Y)과의 관계는 Y = 0.76779X + 0.298354 ($R^2\;=\;0.9599$)의 회귀식을 얻을 수 있었고 높은 상관관계가 있는 것으로 나타났으며, 관계식에 의하면 자연감소율을 5%로 고려할 때 경제적피해수준은 6.1마리/4주로 시설가지에서 생육초기 아메리카잎굴파리 요방제수준은 4주당 4.9마리 범위로 추정되었다.
