摘要

Tomato pinworm Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is one of the major destructive invasive pests spread from South America to several parts of Europe, Africa and to India. Its incidence causes up to 90% yield loss and reduction in fruit quality both under greenhouses and field conditions. Efficacy of certain new molecules viz., spinetoram 12% SC w/v (11.7% w/v) SC at different doses (30, 45 and 54 g ai ha~(-1)), flubendiamide 48 SC @ 60 g ai ha~(-1) and lambda cyhalothrin 5 EC @ 15 gai ha~(-1) were evaluated against T. absoluta in two locations viz., Kaduchittipatti and B. Thrungipatti villages of Dharmapuri District during 2016–17 under open field conditions on hybrids “Sivam” and “Sagar”, respectively. Spinetoram 12% SC w/v was effective at the higher dose of 54 g ai ha~(-1) with the maximum reduction of leaf (89.15 and 88.18%) and fruit damage (95.07 and 89.61%) in both the locations, respectively followed by flubendiamide 48SC@ 60 g ai ha~(-1). These insecticides can be utilized for the management of T. absoluta subject to label claims for use on tomato.
