摘要

近年來，螟蟲危害水稻有逐年增加之趨勢，其中以二化螟蟲、三化螟蟲及大螟蟲發生最多。防治藥劑篩選試驗結果，以6%培丹粒劑30kg/ha及3%加保扶粒劑60kg/ha對螟蟲之防治效果最好。以6%培丹粒劑30kg/ha在不同施藥時期對水稻螟蟲防治效果之比較，結果以水稻移植後25天施藥防治效果最好。不同水稻品種受螟蟲危害之評估，結果以台中秈10號受害最嚴重。

In recent years, the occurrence of rice stem borers, including Chilo suppresalis and Scirpophage incertulas, Sesamia inferens, has gradually increased in the northern Taiwan. The chemical screening test in the paddy field showed that the application of 6 % Cartap Granules with 30 kg/ha and 3 % Furadan G. with 60 kg/ha could give the best control against rice stem borers. Application of 6 % Cartap G. at rate of 30 kg/ha at different rice growing stages showed that application at 25 days after transplanting would give the best control against rice stem borers. A varietal screening test showed that Taichung Sen 10 was most susceptible to rice stem borers.
