Entomopathogenic Viruses in the Neotropics: Current Status and Recently Discovered Species

Area of Science:

• Entomology
• Virology
• Agricultural Science

Background:

• Growing concerns over chemical insecticide impacts on ecosystems and human health drive demand for sustainable pest control.
• Biological control agents, especially insect viruses, offer environmentally friendly alternatives for managing insect pests in agriculture and forestry.
• Baculoviruses are a well-established class of insect viruses, extensively studied and utilized for pest management worldwide.

Purpose of the Study:

• To review fundamental aspects of baculovirus biology, including in vivo and in vitro infection processes.
• To discuss baculovirus gene content and replication mechanisms.
• To highlight the application of insect viruses in biological pest control, with a focus on recent findings in Brazil.

Main Methods:

• Literature review of baculovirus research.
• Analysis of baculovirus infection cycles and genetic makeup.
• Compilation of case studies on insect virus applications in pest control.

Main Results:

• Baculoviruses infect over 700 insect species, predominantly Lepidoptera.
• Detailed understanding of baculovirus infection, gene expression, and replication is crucial for effective application.
• Several baculovirus species have been recently identified and characterized in Brazil, showing potential for local pest management.

Conclusions:

• Baculoviruses represent a significant and growing component of biological pest control strategies.
• Continued research into baculovirus biology and application is essential for sustainable agriculture and forest protection.
• The characterization of novel baculoviruses in Brazil offers promising avenues for region-specific pest management solutions.
