Field Surveys on the Diversity and Damage Severity of Insect Pests in Jackfruit Orchards of Rangpur Division, Bangladesh

Jackfruit ( Artocarpus heterophyllus ) is a vital fruit crop in Bangladesh, playing a crucial role in food security, rural livelihoods, and the national economy. However, jackfruit orchards face significant threats from various insect pests and diseases, leading to substantial yield losses. This study aims to assess the diversity of insect pests affecting jackfruit and evaluate the severity of damage across different districts in the Rangpur Division of Bangladesh. A structured field survey was conducted across eight districts, where data on pest prevalence, damage severity, and management practices were collected through direct observation and farmer interviews. Statistical analysis revealed significant variation in insect pest diversity and infestation rates across districts. Fruit borers ( Dacus dorsalis ), bark-eating caterpillars ( Indarbela tetraonis ), and mealybugs ( Planococcus lilacinus ) were identified as the most prevalent insect pests causing substantial damage. The study highlights the urgent need for effective pest management strategies, including integrated pest management (IPM) and farmer education programs, to minimize losses and ensure sustainable jackfruit production in Bangladesh. Findings from this study provide valuable insights for policymakers, researchers, and farmers to develop targeted interventions for pest control and orchard management.
