Field Survey on Insects and Pests of Potato in Lalmonirhat District of Bangladesh

Potato (Solanum tuberosum L.) is one of the most important food crops in Bangladesh, but its production is significantly affected by various insect pests. A field survey was conducted in Lalmonirhat District to identify the major insect pests affecting potato crops, assess their incidence, and evaluate farmers' management practices. The study was carried out through direct field observations and farmer interviews in five upazilas. The major insect pests recorded were aphids (Myzus persicae), potato tuber moth (Phthorimaea operculella), whiteflies (Bemisia tabaci), and cutworms (Agrotis ipsilon). Aphids were the most dominant pest, with an average infestation rate of 35%, followed by cutworms (20%) and potato tuber moth (15%). Farmers reported using chemical insecticides as the primary control method, while integrated pest management (IPM) practices were limited. The study highlights the need for improved pest management strategies to enhance potato production in the region.
