dc.description.abstractThe study was conducted on the sucking pest complex of tomato, Solanum lycopersicum (L.) and their management using novel insecticides at Hadonahalli village, Doddaballapur taluk, Bengaluru rural district during 2021-22. The sucking pests such as whitefly, thrips, aphids, leafhopper and mites were recorded from the vegetative stage of the crop during the research period. The whitefly, thrips and mites incidence started at two weeks after transplanting of the crop. The peak incidence of both whitefly and thrips was attained during 16th SMW (7.29 /6 leaves and 15.97 /3 shoots, respectively). Meanwhile, the peak population of mites were recorded at 17th SMW (26.91 /6 leaves). Natural enemies like zoophytophagous mirid bug and coccinellid beetle were present throughout the crop period. Correlation studies indicated that, whitefly, thrips and mites showed a significant positive correlation with maximum temperature and minimum temperature. Among the various insecticides evaluated against sucking pests, fidopyropen 50 DC (2ml/lit), Spiromesifen 22.9 SC (1.25ml/lit) and Diafenthiuron 50 WP (1.25g/lit) found effective against whiteflies. Whereas, Spinetoram 11.7 SC (0.9ml/lit), Afidopyropen 50 DC (2ml/lit) and Diafenthiuron 50 WP (1.25g/lit) were effective for successful management of thrips. The highest toxic pesticide against mites were Diafenthiuron 50 WP (1.25g/lit), followed by Spiromesifen 22.9 SC (1.25ml/lit) and Hexythiazox 5.45 EC (0.5ml/lit). The highest fruit yield was registered from the plot treated with Afidopyropen 50 DC (44.32 t/ha) with C:B of 1:2.14, followed by Diafenthiuron 50 WP (43 t/ha) with C:B of 1:2.08 and Spiromesifen 22.9 SC (41.85 t/ha) with C:B of 1:1.99.en_US
