Comparative analysis of the impact of the dried fruit beetle (carpophilus hemipterus) on selected host plant in india

This study examines the dried-fruit beetle (Carpophilus hemipterus), a critical pest impacting India’s fruit crops, including litchi, mango, guava, papaya, custard apple, and dates. It focuses on infestation patterns, economic effects, and pest management strategies. Through field sampling and laboratory experiments, the research analysed the beetle’s life cycle, feeding behaviour, and host preferences, alongside statistical evaluations of crop damage and yield loss influenced by environmental factors such as temperature and humidity. Findings indicate that C. hemipterus demonstrates distinct host preferences tied to fruit ripeness and environmental conditions. Litchi and mango faced the highest susceptibility, suffering significant losses during peak harvests. Guava and papaya were moderately affected, particularly during storage, while custard apple and dates showed localized impacts in areas with inadequate pest management. Infestations reduced market value and export viability, imposing severe economic challenges on small-scale farmers. The study highlights the importance of integrated pest management (IPM) strategies tailored to each crop, combining cultural, biological, and chemical controls. Understanding the pest’s behaviour and environmental triggers is essential for reducing its impact and ensuring sustainable agriculture. Future research should prioritize resistant crop varieties and eco-friendly pest management solutions to safeguard India’s fruit industry and farmer livelihoods.
