Novel Diversity and Virulence Patterns Found in New Isolates of Cydia pomonella Granulovirus from China.

ABSTRACT: Cydia pomonella granulovirus (CpGV) is successfully used worldwide as a biocontrol agent of the codling moth (CM) (Cydia pomonella). The occurrence of CM populations with different modes of resistance against commercial CpGV preparations in Europe, as well as the invasiveness of CM in China, threatening major apple production areas there, requires the development of new control options. Utilizing the naturally occurring genetic diversity of CpGV can improve such control strategies. Here, we report the identification of seven new CpGV isolates that were collected from infected CM larvae in northwest China. Resistance testing using a discriminating CpGV concentration and the determination of the median lethal concentration (LC₅₀) were performed to characterize their levels
