The granulovirus of codling moth, Cydia pomonella L., CpGV, is now commercialized for codling moth control in pome fruit in the USA and Canada. It is highly specific for codling moth and related species. Comparative assays of CpGV against neonate larvae of another introduced tortricid pest, the oriental fruit moth, Grapholita molesta Busck, revealed a 557 and 589 fold lower susceptibility of neonate larvae compared with the LC50 and LC95 values derived for C. pomonella.
