Summary: Surveys to identify insect herbivores of Hydrilla verticillata (L.f.) Royle (hydrilla) (Hydrocharitaceae) were conducted in northern and western regions of Hubei Province and in Jiangxi and Guangdong Provinces from June through November 2012. Bagous sp. 2 weevils were collected in Suizhou from hydrilla and Hydrocharis dubia (Blume) Backer. Host preference testing and attempts at colonization are underway at the Chinese Academy of Sciences (CAS) laboratories in Wuhan. Bagous rufipennis Egorov & Grachev weevils (Bagous sp. 3 in previous reports) have been colonized at the United States Department of Agriculture (USDA), Agricultural Research Service (ARS) Australian Biological Control Laboratory (ABCL) in Brisbane, Australia, where host range testing has been initiated. Moths were common in Guangdong Province but appear to be the generalist Parapoynx diminutalis Snellen. Surveys will recommence in 2013 during the spring and summer period in Hubei Province and other southern China provinces.
