Abstract

Economic injury levels (EILs) and economic threshold (ET) were estimated for the two spider mite, Tetranychus urticae Koch (Acari, Tetranychidae) on greenhouse eggplants. T. urticae density increased until the mid-July and thereafter decreased in all plots where initial density of the mite were different each 0, 2, 5, 10 and 20 adults per plant was innoculated on June 7. Growth variables of were not different among experimental plots but fruit weights were lower in plots with higher initial mite density than in plots with lower initial mite density. Total number of fruits and the number of marketable fruits decreased in plots with higher initial mite density. The rates of yield loss increased with increasing initial mite density, resulting in 0, 3.9, 11.3, 14.5, 22.8% reduction in each of the above plots, respectively. The relationship between initial T. urticae densities and yield losses was well described by a linear regression, Y = 1.085X + 2.474, $R^2$ = 0.9659. Based on the relationship, the number of adults per plant which can cause 5% loss of yield was estimated to be approximately 1.8.

시설재배 가지에서 점박이응애 경제적 피해수준과 요방제수준을 추정하였다. 가지 생육초기 점박이응애 접종밀도(성충 0, 2, 5, 10, 20마리/주)에 따른 시기별 발생밀도는 무접종구를 제외하고 6월7일 접종 이후 점점 증가하다가 7월 5일 이후 급격히 증가하여 7월 중순 발생 피크를 보이고, 이후 서서히 감소하는 경향이었다. 생육최성기 가지 접종수준별 지상부 생육은 처리 간에 큰 차이가 없었고, 과실생육은 과중이 무접종구에 비하여 접종밀도가 높을수록 가벼워지는 경향이었다. 총과수 및 상품과수와 상품과율 및 수량은 접종밀도가 높을수록 감소하는 경향이었고, 그에 따른 수량감소율은 무접종구에 비하여 각각 3.9, 11.3, 14.5, 22.8%로 접종밀도가 높을수록 증가하였다. 점박이응애 접종밀도(X)와 수량감소율(Y)과의 관계는 Y = 1.085X + 2.474 ($R^2$ = 0.9659)의 회귀식을 얻을 수 있었고, 높은 상관관계가 있는 것으로 나타났으며, 관계식에 근거하여 GT값이 전체수량의 5%되는 수량감소율을 추정해 보았을 때 요방제수준은 주당 1.8마리로 추정되었다.
