Evaluation of persistence of Adoxophyes orana granulovirus and Cydia pomonella granulovirus in populations of their hosts by molecular methods
Original language description
Polymerase chain reaction (PCR) based techniques were developed for the detection of AdorGV and CpGV in survived larvae collected in virus treated plots. Primers were based on the granulin gene sequence. Results indicate a strong persistence of AdorGV insurviving larvae after direct treatment causing high mortality of larvae in the next generations. The population density was reduced below the damage threshold within two years after the AdorGV virus treatment. CpGV treatment caused high mortality of C.pomonella larvae in the year of virus treatment. CpGV was found in as many as 15% of the surviving larvae 1 year after treatment in one location. The virus was not detected in CpGV-treated orchards 2 years after treatment. In contrast to persistence ofAdorGV in A. orana population, poor persistence of CpGV in surviving C. pomonella individual was recorded probably resulting in a slow spread in natural host populations.
