Abstract
穀蠹及麥蛾為台灣重要積穀害蟲，添加協力劑piperonyl butoxide(PB)於氨基甲酸鹽及除蟲菊類藥劑中，能有效提升此兩類殺蟲劑對兩害蟲之藥效。在20℃時免敵克添加PB對抗巴賽松品系之穀蠹之協力效果最佳，達12.7倍;在30℃時，與第滅寧效果最佳，達10倍。對麥蛾抗巴賽松品系，添加PB在20℃時與賽滅寧協力效果最佳，達28.7倍;在30℃時與第滅寧最佳，達31倍。因此未來積穀害蟲防治，可應用添加PB於氨基甲酸鹽及除蟲菊中進行防治。
Rhyzopertha dominica and Sitotroga cerealella are major insect pests of stored grains in Taiwan. Synthetic pyrethroids and carbamates synergised with piperonyl butoxide (PB) exerted significant improvements against phoxim-resistant strains of R. dominica and S. cerealella. Synergistic ratios (SR) for phoximresistant strain of R. dominica to bendiocarb was 12.7 at 20℃, while the SR to deltamethrin was 10 to 30℃. The SR for phoxim-resistant strain of the S. cerealella to cypermethrin was 28.7 at 20℃, while the SR to deltamethrin was 31 at 30℃. Combining on of PB with pyrethroids or carbamates is recommended to combat insecticide-resistant strains of R. dominica and S. cerealella in the future.
