Impact of the Dried-Fruit Beetle (Carpophilus hemipterus) on Litchi Production in Bihar: A Study on Life Cycle and Seasonal Population Patterns

The dried-fruit beetle, Carpophilus hemipterus (L.), is a significant pest affecting litchi production, particularly in Bihar, India. This study explores its life cycle on litchi and assesses its population dynamics across different seasons. Field and lab observations show that C. hemipterus completes multiple generations within a single season, with larval feeding causing extensive fruit damage, impacting quality and market value. Population peaks during warmer months, correlating with ideal temperature and humidity for beetle proliferation. These findings suggest an urgent need for integrated pest management tailored to Bihar’s conditions, including timely eco-friendly insecticides, and biological controls to protect the litchi crop and support local farmers.
