Entry quarantine bean weevils intercepted in imported grains
China is a major grain importer,and the frequent detection of quarantine bean weevil at ports poses a serious threat to grain security.From 2015 to 2018,domestic ports intercepted at least 19 species of bean weevil pests,with the highest number of interceptions being Callosobruchus chinensis.These bean weevils are primarily transmitted by imported legumes and other grains,originating from a variety of complex sources and in large quantities.Quarantine data indicates that Myanmar,Vietnam,and Thailand are among the top countries in terms of bean weevil interceptions,with Kunming,Shenzhen,and Nanjing customs being the primary ports of interception.There are various species of bean weevils,and they parasitize on various types of beans.The damage caused by different bean weevils to different hosts also varies.Efforts to strengthen quarantine inspection and monitoring are crucial to effectively prevent and control the introduction and spread of bean weevils.
