Encyrtidae of California


The Encyrtidae (Hymenoptera) comprise one of the most important groups of insects used for the biological control of economic pests. However there has never been a systematic attempt to characterize the Nearctic fauna. As a preliminary to such a study, I am compiling a checklist of the species found in California, including both native species as well as those established here in biocontrol programs.
