摘要

本研究主要為探討基徵草蛉（Mallada basalis（Walker））對二點葉蟎之防治成效，本研究以草莓為材料，評估基徵草蛉釋放對田間草莓二點葉蟎族群密度的影響，三種處理，包括草蛉綜合防治（IPM）、化學藥劑（CP）及不防治（CK）組，結果顯示二點葉蟎族群密度於草莓定植後逐漸上升，於1月上旬達最高，草蛉綜合防治處理下二點葉蟎最高密度在31.4隻、化學藥劑處理下462.2隻及不防治對照組344.8隻，顯示於草莓生育期持續釋放草蛉幼蟲，可有效控制二點葉蟎密度，但化學藥劑處理並無法有效降低二點葉蟎密度。

In order to understand the effect of lacewing (Mallada basalis (Walker)) on the density of two-spotted spider mites (Tetranychus urticae Koch) in strawberry, three treatments, including lacewing-oriented pest management (IPM), chemical pesticide (CP), and control (CK), were performed in this study. The result showed the density of two-spotted spider mites increased as strawberry growth, and the maximum density was on January. The maximum density was 31.4, 462.2, and 344.8 per leaf for IPM, CP and CK, respectively. It suggested continuous release of lacewing larvae could reduced the density of two-spotted spider mites in the field. However, the chemical pesticide has no effect on reducing population of two-spotted spider mites in strawberries.
