Yield response to girdling by the girdle beetle Obereopsis brevis (Swed.) on different plant parts of soya bean
A study of the impact of girdling, caused by the girdle beetle Obereopsis brevis (Swed.), on different plant parts of soya bean variety JS 76-205 revealed that the beetle inflicted maximum girdle formation on the petiole (43.1%), followed by on the branch (22.6%), stem (21.5%), and petiolet (12.8%). Plants with girdles on the main stem suffered 15.74% premature morality and the highest grain weight loss (47.2%), followed by girdles on the petiole, branch, and petiolet which accounted for a grain weight loss of 40.3, 39.9, and 30.2%, respectively.
