Chlorantraniliprole resistance in diamondback moth on different locations of Maharashtra

Author(s): RS Yeole, PN Sangale and SB Damal
Abstract: Diamondback moth (Plutella xylostella L.) is one of the few insect species that has developed field resistance to all major classes of insecticides and is ranked second in the Arthropod Pesticide Resistance Database (APRD) for the highest number of insecticides which reported resistance in at least one population. In this view, the present investigation was framed to study the levels of insecticidal resistance in the larvae of diamondback moth collected from major cabbage growing districts of Maharashtra at Post Graduate Laboratory, Department of Agricultural Entomology, College of Agriculture, Latur (V.N.M.K.V., Parbhani) during Kharif 2015. Based on variations in LC50 values and comparison with recommended dosages, the insecticidal resistance in cabbage diamondback moth from different locations of Maharashtra region was quite alarming to chlorantraniliprole, The resistance ratio to chlorantraniliprole 18.5 per cent SG was found to be highest in the diamondback moth population of Nashik (12.8-fold) followed by Ahmednagar (6.25-fold), Osmanabad (4.76-fold), Solapur (3.62-fold), Pune (2.80 -fold) and Latur (2.07-fold). Compared with the susceptible strain only Nashik population of diamondback moth (12.8-fold) indicated low resistance while, other field populations (83.33 per cent) i.e. Osmanabad, Solapur, Pune, Latur and Ahmednagar showed decreased susceptibility to chlorantraniliprole 18.5 per cent SG.
