Give It A Virus: Apple growers have a new defense in their battle with codling moth.

摘要

MANY apple growers continue to do battle with codling moth (CM) and Oriental fruit moth (OEM). While they may rely on insecticides as their principal control tool, more and more growers are also adding sex pheromone mating disruption to their management toolbox. Despite the loss of some valuable insecticides due to the Food Quality Protection Act (FQPA) and the development of insecticide resistance, the toolbox for the control of the internal fruit-feeding complex continues to expand each year. Amongthe many new tools available is a naturally occurring virus that was identified in 1964 in Mexico on infected CM larvae. Because of its high selectivity toward this pest, it is called the codling moth granulovirus (CpGV).
