My research focuses mostly on a group of insect-specific viruses known as baculoviruses, which are classified in the family Baculoviridae. 

These viruses form distinctive structures known as occlusion bodies, which contain the infectious particles of the virus within a protective crystalline matrix composed of a single viral protein. Hosts of baculoviruses are usually larvae of moths and butterflies, although some baculoviruses also have been found to infect sawflies and mosquitoes.

Baculovirus occlusion bodies forming in infected cells of the fall armyworm (Spodoptera frugiperda) Sf9 cell line.

These viruses establish lethal infections and are the cause of naturally-occurring  epizootics in the field populations of their hosts, accompanied by dramatic population declines.  The occlusion bodies can be harvested from virus-killed insects and applied to control infestations of insect pests with no impact on other organisms.  For these reasons, baculoviruses are under active investigation and development as biological pesticides.

Over the course of decades, scientists at IIBBL have accumulated more than 2600 samples of insect viruses representing 142 different insect hosts and/or virus species.  We work to identify and classify baculoviruses in samples of interest, both from our collection and obtained from other sources, and characterize them with respect to their relationships with other viruses and their pathogenicity against significant agricultural pests, such as the fall armyworm and the spongy moth.  This research has contributed to the development of a biopesticide, Fawligen, which is produced and marketed for use against fall armyworm and beet armyworm populations.

We also study iflaviruses, which are found in a wide variety of arthropods.  These viruses can cause mortality and disease in their hosts, but in the brown marmorated stink bug and the spongy moth, iflaviruses accumulate to very high levels without any obvious pathology.  We are interested in the impact these viruses are having on their hosts and in their interactions with baculoviruses.
