Status of acaricide resistance in field collected two-spotted spider mite, Tetranychus urticae Koch from vegetable growing areas of Punjab, India

Rakesh Kumar Sharma and Manmeet Brar Bhullar

Two-spotted spider mite (TSSM), Tetranychus urticae Koch (Acarina: Tetranychidae), has gained importance in view of their widespread occurrence as a pest on vegetables in Punjab. So far, Scanty information is available on the status of acaricide resistance in T. urticae populations in North India. So the study was conducted in 2015-16 to monitor the magnitude of resistance in T. urticae on brinjal against different acaricides viz., propargite, spiromesifen, fenpyroximate and fenazaquin collected from different vegetable growing areas (Amritsar, Hoshiarpur, Malerkotla and Patiala) of Punjab. Patiala population was least susceptible to fenazaquin (RR 24.65) among all tested acaricides while Amritsar population was found to be highly susceptible (RR 6.67) Among all tested acaricides, fenpyroximate (0.00205 – 0.00954 per cent) was found to be the most toxic against all the tested populations except Malerkotla population. Low to moderate levels of resistance (3.19-24.65 fold) was reported in T. urticae to tested acaricides in Punjab.
