Abstract
Baculoviruses are occluded DNA viruses that are lethal pathogens to larval stages of several lepidopterans, mosquitoes, sawflies with the peculiar nature that they are host specific. The entry of this virus into an insect is per os and both virus types enter midgut cells (primary site of infection) by membrane fusion and the virions are liberated by the action of alkaline digestive juice and finally lead to a systemic infection of the hemocoel which ultimately leads to the death of the insect. As baculoviruses are host specific the much preferred in integrated pest management.
