Weather Parameters Affecting the Population Dynamics of Leaf Folder and Pod Borers on Mungbean

Abstract

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.

Field evaluation of promising mutants of mungbean against Fela Beetle, Aphid and POD Borer

“…The findings of the present study agree with the results of Islam et al (2021) where they stated that varieties did not show complete resistance against major insect pests of mungbean. Our results are also in comparison to work of the previous researchers (Sahoo and Hota, 1991;Naqvi et al 1995;Yadav and Dahiya, 2000;Singh and Singh, 2014) who reported that the findings regarding screening of mungbean cultivars against sucking pets are in the line of the results that we have attained in our study.…”

Integrated management of flea beetle and thrips on mungbean in coastal habitat

“…In addition, it has the ability to fix atmospheric nitrogen (58-109 kg/ha) in symbiotic association with Rhizobium bacteria, which not only covers its own needs, but also promotes subsequent cereal crops in various cultivation systems, thus enriching soil fertility (Anjum et al, 2006;Pratap et al, 2013). However, there are many limitations to its low yield, insect pests are considered important (Islam et al, 2021).…”
