MATING DISRUPTION AND CYDIA POMONELLA GRANULOSIS VIRUS FOR CONTROL OF CODLING MOTH IN PEAR

Studies initiated in 2003 with two Cydia pomonella granulosis virus (CpGV) products, Cyd-X and Carpovirusine, showed that frequent applications of CpGV gave 80–90% control of codling moth, Cydia pomonella, in a Research Center orchard where the codling moth population was high.
An on-farm trial indicated that CpGV worked well in combination with mating disruption (MD) in an orchard where the codling moth population was low.
During 2004 and 2005 replicated trials with CpGV were conducted in high pressure blocks with and without mating disruption to try and determine the effect of each tactic by itself and in combination.
The addition of CpGV always resulted in a significant reduction of successful codling moth entries but stings, or unsuccessful entries, were increased as the CpGV must be ingested by the codling moth larvae to be effective.
The 2004 trial showed that CpGV could be as effective as conventional insecticides when applied twice as often.
When results from blocks with and without MD were compared it appeared that most of the codling moth control in the combination program came from the CpGV applications.
