摘要

番茄斑潛蠅Liriomyza bryoniae為多種蔬菜生長初期之主要害蟲，深具經濟重要性。由1987～1988前後兩次用15種殺蟲劑，作番茄斑潛蠅防治比較試驗結果，以Trigard 10％SL和Decis 2.8％EC兩種殺蟲劑效果最優，尤以前者較後者為優。Ofunack 40％EC和Evisect 50％WP效果較差。供試殺蟲劑對寄生蜂之影響和對照區比較各有差異。第一年（1987）以Atabron, Decis和Trigard三者對寄生蜂Halticoptera circulus（Walker）都有不良影響，其餘均無不良影響。第二年（1988）仍以Decis對H. circulus和Opius phaseoli Fischer有不良影響，其餘僅Pay-off和Evisect亦有影響外，大都對H. circulus無不良影響。兩種寄生蜂以H. circulus之寄生率較O. phaseoli為高。前者對殺蟲劑亦較後者具有不感受性。

The tomato leafminer, Liriomyza bryoniae, was found as a new record insect pest on Taiwan in 1984. It causes very serious damage on many families of vegetables during their early growing stage. 15 insecticides were evaluated from 1987 to 1988 for the control of the leafminer on head mustard Brassica juncea. The results showed that Trigard 10% SL was the best among the insecticides in both of the trials. Decis 2.8% EC, Ofunack 40% EC and Evisect 50% WP also performed good effectiveness. The parasites, Halticoptera circulus and Opius phaseoli, rarely appeared on both trials of the Trigard and Decis plots. Evidently, these insecticides were very harmful to the parasites as comparison with the other insecticides tested.
