摘要

在臺灣儲藏之稻穀、糙米及粗糠中計發現21種害蟲，稻穀及粗糠中以穀蠹（Rhyzopertha dominica）為主，糙米中則以象鼻蟲類（Sitophilus spp.）佔多數。不同地區的蟲相亦有差異，東部稻穀以麥蛾（Sitotroga cerealella）為主。目前臺灣之穀倉型式以鋼筋倉及磚造倉為主。不論倉型及地區，稻穀倉中象鼻蟲種類以米象（Sitophilus oryzae）佔優勢。不同倉型中，以鋼筋倉及磚造倉中之蟲口密度變化較大。在乾冷地區，通風較佳之穀倉，蟲害發生較不嚴重。

The species and density of stored products insect pests were varied with different types of stored rice. The lesser grain borer, Rhyzopertha dominica, was the dominant pest observed in rough rice and chaff. The density of Sitophilus spp. was, however, the highest in brown rice. Insect pests were also observed to be different in different areas in Taiwan. The key pest of rough rice in the east area was the Angoumois grain moth, Sitotroga cerealella. In rough rice, the key species in Sitophilus was the rice weevil, Sitophilus oryzae. The population dynamics of stored products insect pests in concrete and brick bins fluctuated monthly. The occurrence of insects was less serious in well-ventilated bins in dry and cool area.
