Implementation of Biological Control

One of the most satisfying aspects of our work is that the understanding gained from our research on population ecology and natural enemies can be directly linked to the improvement of biological control practice. Recent projects include:

• Classical biological control of codling moth (Cydia pomonella), light brown apple moth (Epiphyas postvittana), and mealy plum aphid (Hyalopterus pruni), the latter making use of molecular markers to understand population structure and guide the collection of compatible parasitoids for introduction to California
• Understanding the role of climate and pesticides in conserving the biological control of walnut aphid (Chromaphis juglandicola) and spider mites (Tetranychus pacificus and Eotetranychus willamettei) in vineyards
• Landscape influences on biological control of lettuce aphid (Nasonovia ribis-nigri)
