ABSTRACT: The study was done to find out the influence of weather parameters on the abundance and damage severity of epilachna beetle on brinjal, grown at Patuakhali Science and Technology University (PSTU) campus, Patuakhali during June 2021 to May 2022. Results revealed that the highest abundance of grub (34.0) was recorded in May and the lowest abundance (3.0) was noticed in November followed by no beetle in December. The highest leaf area damage (78.0%) was recorded in May and the lowest leaf area damage (36.0%) was noticed in January. The highest damaged area (504.48 sq. mm leaf -1) of infested leaf was measured in May, whereas the lowest damaged area (158.98 sq. mm leaf -1) was found in January. The population of grubs and adults of epilachna beetles was positively correlated to the maximum temperature while they were negatively correlated to the minimum temperature and relative humidity.
Keywords: Coccinellid beetles, leaf feeders, climatic factors, pest management.
