The California Department of Food and Agriculture (CDFA) Biological Control Program is rearing an agent for an invasive stink bug in California. An adventive population of Trissolcus japonicus, the co-evolved egg parasitoid for brown marmorated stink bug, Halyomorpha halys, was first discovered in Los Angeles County, California in 2017. Trissolcus japonicus established is southern California, however it has not yet made it into the more coastal, interior, or northern California counties such as Santa Clara, Stanislaus, or Siskiyou counties. Redistribution efforts in infestation hot-spots continue to improve H. halys management in the state. Current efforts by the CDFA Biological Control Program will be discussed.
