“…These results also resonate with the findings of Kaur et al (2021), who conducted bioassays against, S. litura, noting second instar larvae were more susceptible and easier to kill than the fourth instar larvae. The observed results align with the research conducted by Kindozandji et al (2022), wherein they documented variable levels of MaviMNPV-induced larval mortality, ranging from 15± 0.63% to a complete mortality of 100± 00%. The extent of larval mortality was noted to be dependent on the specific developmental stages of the larvae under investigation.…”

This study explores the potential of nucleopolyhedroviruses (NPVs) as a sustainable solution for managing legume pod borer Maruca vitrata (F). Distinctive signs of viral infection, such as suspended deceased larvae on cowpea leaves, and virus spread have been observed. Microscopic examination reveals characteristic polyhedral inclusion bodies (PIBs), confirming MaviNPV as the causative agent. Symptoms, including decreased activity and mortality in younger larvae, larval-pupal intermediates and deformed pupae have been observed. Reproductive disruption is evident through the absence of an egg mass and discharge of fluid from emerged adults. Bioassay results highlight age-dependent susceptibility, with higher mortality in early instars.
