葱薊馬Thrips tabaci Lindeman是蔥、菲、蒜等石蒜科蔬菜之重要害蟲，其以銼吸式口器銼食植株之葉部，花部，致使產量、品質影響很大。因蔥薊馬體小，且成蟲善跳躍，故用特製之薊馬收集器，以100W 燈照1 天即可採到99.74 %之蟲數。其發生蟲數與其為害葉片呈一明顯之相關性，成蟲數（x）和為害葉率（Y）求得之迴歸方程式為Ŷ＝4.6998＋l.1767x ( r=0.9712 )，幼蟲數（x）和為害葉率（Y）之迴歸方程式為Ŷ＝0.5690＋0.520lx（r = 0.9891 ）兩者均為頭著正相關。藥劑試驗中以Furadan 40.64 % FP 800X 、Decis 2.5 %EC 2000X 、Mesurol 50 %WP l,000X、Tamaron 50 % S 1200X、Folimat 50 % S 1,500X 等之防治率高於90 %，以供防治之參考。
Onion Thrip, Thrips tabaci Lindeman, has been one of the major insect pest on Amaryllidaceae in the world. The thrips sucked the sap from leaves and flowers by rasping-sucking mouth parts. It caused white spots on the leaves, production decreasing and sterility of host plant. The regression formula between the occurrence number of thrips (X) and percentage of infesting leaves (Ŷ) was Ŷ =4.6998+1.1767X (r=0.9712) in adults, and Ŷ=0.5690+0.5201X (r=0.9891) in larvae. Both of them were positive correlated. Nine insecticides were used for screening test. Those which showed promising control effect were Furadan 40.64% FP, Decis 2.8% EC, Mesurol 50% WP, Folimat 50% S, and Tamaron 50% S. Over 90% of the thrips were killed by the application of these chemicals.
