摘要

茄子是高屏地區重要蔬菜，從種植到收穫常發生許多病虫之危害，其中神澤氏葉蟎為主要之害蟎。本害蟎全年均可發生，從每年12月到翌年1－2月為其高峰盛期，農民混合多種藥劑防治它，結果仍不甚理想。本試驗使用殺劑係根據農民常用及植保手冊推薦在其他作物上之殺蟎劑共23種，進行室內及田間試驗，評估其殺蟎藥效。經實驗室初步篩選結果顯示，以7.5% Fenpropathrin + Hexythiazox E.C. 1,000倍、2% Abamectin E.C. 2,000倍、68.1% Propargite E.C. 1,000倍、2.8% Cyhalothrin E.C. 1,000倍、5% Fenpyroximate F.P. 1,000倍等5種藥劑，對神澤氏葉之防治效果良好。它們經田間三個不同地點試驗結果亦顯示很好藥效，唯2.8% Cyhalothrin E.C.防治效果較差，於三地之效果不甚理想。

Eggplant is an improtant vegetable crop in Kao-Ping area. They are suffered from many diseases and insect pests when they planted in the fields. Among them, the Kanzawa spider mite (Teteranychus Kanzawai Kisida) is one of the major pests. The Kanzawa spider mite occurred year round and its peak appeared from December to January or February of the following year. For controlling this insect, farmers used to spray mixed pesticides to control it, yet it is still ineffective. Twenty-three pesticides selected from greenbook or from farmer's recommendation were used for evaluation in the laboratory. The results from the laboratory tests indicated that five pesticides, such as 7.5% Fenpropathrin + Hexythiazox (1,000x), 2% Abamectin (2,000x), 68.1% Propargite (1,000x), 2.8% Cyhalothrin (1,000x), and 5% Fenpyroximate (1,000x) were effective for controlling the Kanzawa spider mite. They were further tested in the fields at three sites. The results showed that all five insecticides, except 2.8% Cyhalothrin were effective against the Kanzawa spider mite. Pesticide residual analyses were also determined by the biochemical assay,and the results revealed that fruits of the eggplants were free from pesticide residul and safe for consumption.
