Egg parasitism of the invasive, light brown apple moth (Epiphyas postvittana) in California

The seasonality and geographic distribution of naturally occurring Trichogramma spp. parasitizing eggs of the exotic light brown apple moth in coastal regions of California was studied using sentinel egg cards. In all, 5 species have been identified. Two species are dominant (T. platneri and T. fasciatum). The collection of T. fasciatum in this study is the first time this species has been found in the United States. Seasonality and geographic population patterns have been identified.
