| Popis: | The experiment was conducted to know the abundance of major insect pests on 15 mungbean varieties viz., BARI Mung-1, BARI Mung-2, BARI Mung-3, BARI Mung-4, BARI Mung-5, BARI Mung-6, BINA Moog-4, BINA Moog-5, BINA Moog-6, BINA Moog-7, BINA Moog-8, BU Mug-1, BU Mug-2, BU Mug-4 and Patuakhali local Mung and the role of weather parameters on the population mobility of insects at the farmer’s field of sadar upazila of Patuakhali district, Bangladesh during late Robi season 2016. Variety BARI Mung-4 had the lowest number of leaf folder while variety BARI Mung-6 had the highest number of leaf folder indicating higher susceptibility to leaf folder. Variety BARI Mung-4 had the lowest number of gram pod borer and BARI Mung- 6 had the highest abundance of gram pod borer followed by BINA Moog-7. Variety BINA Moog-4 had the lowest number of legume pod borer and BARI Mung-6 had the highest abundance of legume pod borer followed by BINA Moog-7. Population of leaf folder showed a negative correlation (R2= -0.020) with temperature. Similarly, gram pod borer (R2= -0.317) and legume pod borer (R2= -0.014) showed a negative correlation with temperature. In case of relative humidity, population of leaf folder (R2= -0.175) showed a negative correlation while gram pod borer showed a positive correlation (R2= 0.031) but legume pod borer (R2= -0.086) showed a negative correlation. |
