Abstract
An investigation was undertaken to study the screening of onion varieties against thrips Thrips tabaci Lindman in the Grid region of Madhya Pradesh, India. Twelve onion varieties were sown, and different levels of thrips incidence were observed over two successive years (2022–23 and 2023–24). The results indicated that none of the varieties were completely free from thrips incidence. Among the twelve varieties, two were categorized as highly susceptible, eight as moderately susceptible, and two as less susceptible. The variety Light Red had the lowest thrips population, followed by Bhima Shweta. The highly susceptible varieties, Nasik Red (N-53) and Gauran LR-241, recorded the highest thrips populations.
