在2003～2012年間，台灣每年從國外進口約900萬噸之大宗穀物，以供應民生及農業需求。針對進口穀物害蟲之檢疫，並防範檢疫害蟲隨貨品入侵，就極為重要。本調查自2003年起先針對台中港進口之大宗穀物進行害蟲發生調查，在2007年起對高雄港進口之大宗穀物也一併調查。由兩港口在十年間之調查結果顯示，自2003～2012年共調查1,086件樣品，含害蟲率達22.6%，均未發現檢疫害蟲。總共檢出22種害蟲，其中以米象（Sitophilus oryzae）發現率最高。五種主要進口大宗穀物中，以玉米之樣品含蟲率最高，達33.2%。穀物進口來源包含21國，其中從印度進口之樣品含蟲率最高，達56.8%。由於印度為重要檢疫害蟲小紅鰹節蟲（Trogoderma granarium）疫區，因此由印度進口穀物導致檢疫害蟲入侵之機率將明顯提升。未來針對檢疫害蟲發生疫區之進口穀物，建議應加強害蟲之檢疫調查及防範，以杜絕檢疫害蟲之入侵。
Between 2003 and 2012, each year approximately nine million tons of bulk grain were imported into Taiwan to meet the demand. Quarantining this grain is extremely important in order to prevent an invasion of the insects that come with the grain. A survey of pests in imported bulk grain was conducted in Taichung Harbor starting in 2003, and in Kaohsiung harbor since 2007. The results indicated that live insects were found in 22.6% of the 1,086 samples of bulk grain, but none of them were quarantine pests. Twenty-two insect species were identified, of which Sitophilus oryzae was the most dominant one. Imported bulk grain consisted of five main crops. The insect containing rate for corn samples was the highest at 33.2%. These crops came from twenty-one different countries, with those from India having the highest insect containing rate at 56.8%. Because Trogoderma granarium is native to India, the invasion probability of this quarantine pest is increased through grain imports. It is therefore recommended that surveillance and preventive measures for this pest are increased so as to prevent its invasion through imported grains.
