First Report for Pathogenity of Cydia Pomonella Granulovirus and Helicoverpa Armigera Nucleopolyhedrovirus to Indian Meal Moth Plodia Interpunctella Hϋbner (Lepidoptera: Pyralidae) in Vitro

Abstract: The purpose of this study was to examine the for the first time the effect of Cydia pomonella granulovirus and Helicoverpa armigera nucleopolyhedrovirus on the larvae of the Lepidopteran Plodia interpunctella. L3 larvae were tested to see whether they were influenced by the infection of the two entomopathogenic viruses Cydia pomonella granulovirus and Helicoverpa armigera nucleopolyhedrovirus. The experiment lasted seven days. The results showed that the effect of the two Baculoviruses was statistically important in relation to the control. The effect of the virus H. armigera nucleopolyhedrovirus was greater than the effect of the virus C. pomonella granulovirus, and this led us to the assumption that the use of entomopathogenic viruses can play an important role in controlling P. interpunctella larvae. The recorded mortality after 7 days was for larvae treated with C. pomonella granulovirus 33.3 to 86.7%, with H. armigera nucleopolyhedrovirus 53.3 to 93.3% and control mortality was 0.7%. This information may appear particularly useful in the future control of the insect’s populations in the warehouse.
