摘要

茄子為高屏地區重要秋冬季蔬菜，農民為確保品質及產量，減少葉片受南黃薊馬為害，以避免日後茄果有疤痕出現，故大都以5－6種藥劑混合且每7－10天施藥一次來防治薊馬。而茄園一星期可採1－2次，上述防治方式易造成農藥殘留，危害消費者健康。藥劑篩選結果顯示：2.8%第滅寧乳劑、2.8%賽洛寧乳劑、50%滅賜克可濕性粉劑、9.6%益達胺乳劑等藥劑對南黃薊馬致死效果最好。化學殘留檢驗結果以愛殺松之檢率最高，而生化檢驗方面，只有50%愛殺松500倍+2.8%第滅寧500倍+40.64%加保扶500倍之藥劑處理檢驗結果高於50%，利用黃、藍色黏板誘殺試驗結果顯示，藍色黏板誘殺效果為黃色之10倍，可做為綜合防治時輔助誘殺的工具，其餘農藥之檢驗結果無化學殘留。

Eggplant is one of most important winter vegetables in Kao-Ping area. To ensure crop production, fruit quality and no leaf damages, farmers usually mixed 5-6 pesticides and sprayed at 7-10 day intervals. However, eggplants were harvested 1-2 times per week, therefore, the frequency of pesticide usage would result in residue problems and endanger consumer health. Pesticide screening test showed that 2.8% Decamethrin, 2.8% Cyhalothrin, 50% Metemercapturan, and 9.6% Imidacloprid were able to efficiently control Thrips palmi (Karny). Chemical residue tests showed that organophosphate - Ethion had the highest detecting ratio. However, in biological residue tests only the residues of 50% Ethion 500 times+2.8% Decamethrin 500 times+40.64% Carbofuran 500 times were detected. Yellow or blue sticky board tests showed that the blue color treatment yielded 10 times more in attracting the thrips than yellow one, As such, blue sticky board could be used to trap thrips as a complementary control measure to pesticides.
