The Envirnoment Friendly Managemet of Thrip Species in Cotton Crop

Management of thrips species in cotton crops

Abstract

Environment friendly integrated pest management (IPM) tools were implemented for to reduce population of thrips species, Thrips tabaci (Lind.) and Frankliniella fusca (Hinds) and usage of insecticides in cotton filed. The field experiments were conducted on the attractiveness of different colour sticky traps i.e., yellow, blue, red, pink, green and white. Each treatment was consisted with five cards, and adjusted in each replication. The results of colour sticky traps, the T. tabaci was attracted with a greater number on yellow, followed by green colour sticky traps. However, F. fusca attracted with huge numbers on red and yellow coloured traps, whereas the lowest on blue and white sticky traps. The results of neem plant leaves and seed extracts proved to be the most effective and reduced above 50% Thrips species population after 72 h of application, while all dosages of neem derivatives at 24, 48 and 168 h became the least effective to decline above 50% Thrips population. The result of selective insecticides revealed that Acephate 75% WP, Imidacloprid 20% SL and Chlorfenapyr 360% SC caused above 50% mortality of thrips species with application of all dosages, except Acephate at 250gm and Imidacloprid at 200 and 400 ml after 168 h, while Chlorfenapyr at 100 and 200 ml after 72 and 168 h of application remain below 50% population of thrips, respectively. The conclusion of studies was that the colour sticky traps and plant extracts proved to be environment-friendly tools to significantly reduce thrips species in cotton crop.
