Arthropods (i.e., insects and mites) weeds, and plant pathogens (e.g., fungi and bacteria) are serious pests that pose a significant threat to our natural resources, food crops and urban environments. The invasion of exotic pests into California is increasing due to globalization of trade and travel. Recent examples of new serious exotic arthropod pests are the glassy-winged sharpshooter (Homalodisca coagulata) (affecting grapes and citrus and attacking woody native plants), giant whitefly (Aleurodicus dugesii) and red gum ler...

Biological Control Workgroup
Biological control projects are being conducted by UC, CDFA, & USDA personnel. While each agency faces similar issues, there is often little coordination or extension of activities. This problem will be addressed under two broad objectives: (1) assess issues that impact regulation and practice, and (2) improve communication, cooperation and extension. To accomplish these objectives, issues pertinent to California biological control will be addressed by Subcommittees. Preliminary discussions have identified several Subcommittee issues, including: (a) pre-release evaluation of natural enemies, (b) post- release assessment, (c) funding development for I&Q operations and foreign exploration, (d) improved interagency communication, (e) improved extension tools.
