Popis: To evaluate population fluctuations in relation to weather parameters and biorational management of sucking insect vectors in chili (Capsicum annuum L.), we conducted a study at the experimental field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, in 2020 and 2021. It has been shown in this study that sucking insects (aphids, jassids, whiteflies, and thrips) were active throughout the study period. The highest count of sucking insect vectors (24.67 aphids, 13.72 whitefly, and 56.56 thrips) in March and (14.83 jassid) in April was recorded at average temperatures of 34-36°C and 31°C, respectively. There was a positive correlation between pest abundance and temperature, relative humidity, and rainfall for all insects, with the exception of a negative correlation between whiteflies and temperature and rainfall. The results of linear regression models showed that abiotic factors contribute to pest abundance levels, with 100R
