RELATIVE SUSCEPTIBILITY OF EXISTING GROUNDNUT VARIETIES AGAINST SUCKING INSECT PESTS, HAIRY CATERPILLAR AND LEAF ROLLER (Pages : 1 - 5)

The experiment was conducted during the Rabi 2022 and 2023 seasons at the research field of Oilseed Research Centre (ORC), Bangladesh Agricultural Research Institute (BARI), Gazipur, Bangladesh, to determine the relative susceptibility of BARI-released groundnut varieties to insect pests, leaf rollers and hairy caterpillars. The population of whiteflies was more abundant during the early growth stage, while jassids and thrips were more abundant during the advanced growth stage of crops in both years. Over two years, the lowest amount of whitefly was obtained with Basonti Badam, BARI Chinabadam-6, BARI Chinabadam-7 and BARI Chinabadam-10. The greatest amount of jassid was found in the Dhaka-1, Tridana Badam and BARI Chinabadam-11 varieties, which included Jhinga Badam. The Thrips population was greater for all varieties in both years. The greatest percentages of plant infestation by leaf rollers were observed for Dhaka-1, Jhinga Badam and BARI Chinabadam-11, but not for Tridana Badam. Hairy caterpillars were most abundant in Dhaka-1, Tridana Badam, and Jhinga Badam. As far as the cultivars are known, Dhaka-1, Tridana Badam and BARI Chinabadam-11 were found to be relatively susceptible, while Basonti Badam, BARI Chinabadam-6 and BARI Chinabadam-7 were relatively resistant in both years. The findings of this study will be helpful for ensuring the sustainability of groundnut production under a changing climate.Download
