Paper Title:
Population dynamics and efficacy of newer molecules of insecticides against red spider mite, Tetranychus urticae Koch on Yard long bean, Vigna Unguiculata Subsp. Sesquipedalis
Field experiments were conducted to study the population fluctuation of two spotted red spider mite (Tetranychus urticae Koch) in relation with different weather parameters and efficacy of newer insecticides against major pests of yard long bean during 2018-2019 under unprotected conditions at AHRS, Bhavikere, UAHS, Shivamogga, Karnataka. During Kharif, the results revealed that the mite population commenced from 37th to 48th standard week. Mite population ranged from 5.02 to 13.70 mites per 2.5 cm2 leaf area. During Rabi, the mite population ranged from 1.69 to 21.50 mites per 2.5 cm2 leaf area. The incidence of mites in both seasons showed significant and positive correlation with maximum temperature. Whereas, minimum temperatur, maximum relative humidity, minimum relative humidity and rainfall showed a significant and negative correlation with mite population. Among the insecticides tested, the highest percent reduction of mites was recorded in the treatments Spiromesifen 22.9 SC (85.60 %) followed by Fenazaquin 10 EC (82.95 %), Diafenthiuron (78.38 %) and Chlorfenapyr 10 EC (73.40 %). However, least percent reduction of mite population was observed in azadirachtin (51.79 %) treated plot when compared to untreated control.
