Prof. Dr. Mahbuba Jahan is a Professor in the Department of Entomology at Bangladesh Agricultural University (BAU), Mymensingh. Her extensive research career spans over three decades, focusing primarily on agricultural entomology and pest management in rice and other crops. She conducts field and laboratory studies at BAU's entomological facilities and has collaborated with the Bangladesh Rice Research Institute (BRRI). Dr. Jahan's research interests center on agricultural entomology, particularly pest management strategies for rice crops. Her work extensively examines brown planthopper resurgence phenomena, insecticide efficacy and resistance, biological control methods, and integrated pest management approaches. She investigates the complex interactions between insecticides, pest populations, and natural enemies in rice ecosystems. Her research also extends to vegetable crop protection, including brinjal and bitter gourd, as well as exploring botanical alternatives to synthetic pesticides. Analysis of her publication record reveals a clear evolution in research focus. Early work (1990s-2000s) concentrated on fundamental biological control mechanisms, particularly parasitoid behavior. From the 2010s onward, her research shifted toward practical field applications, with increasing emphasis on farmer perceptions, economic impacts, and sustainable pest management solutions. A significant portion of her recent work (2016-2021) addresses the critical issue of pest resurgence, particularly with brown planthopper in rice systems, and evaluates both chemical and non-chemical control methods. Her research methodology typically involves field experiments in randomized complete block designs with multiple replications, laboratory bioassays, and sometimes farmer surveys across multiple regions of Bangladesh. She frequently collaborates with colleagues from various agricultural research institutions across the country.
