Abstract
Five insecticides viz., dimethoate, indoxacarb, flubendiamide, spinosad and fenazaquin were evaluated for their toxicity against beetles of Brahmina coriacea (Hope) using leaf dip and topical application methods. In leaf dip method, LC50 values of these were 8.41, 165.20, 186.66, 246.09 and 460.60 ppm, respectively, while LC90 values were 45.07, 143.71, 1749.55, 1541.82 and 2687.70 respectively. The order of toxicity was dimethoate> indoxacarb> flubendiamide> spinosad> fenazaquin. In topical application method, LC50 values were 69.71, 201.90, 415.42, 474.66 and 492.19 ppm, respectively; and LC90 values were 300.30, 1077.32, 2121.14, 2672.20 and 3083.64 ppm, respectively. The order of toxicity was indoxacarb> dimethoate> flubendiamide> fenazaquin> spinosad. Irrespective of insecticides, leaf dip method of bioassay proved more effective (except indoxacarb).
