Abstract : An experiment was conducted from the end of March to the end of May 2004 and 2005 in West Bengal, India, to evaluate the bioefficacy of neem spray aza 3000 EC (2, 3 and 4 ml/litre), cypermethrin 10% EC (1, 1.5 and 2.0 ml/litre), DC tron plus (2, 3 and 4 ml/litre) and fenpropathrin 30% EC (0.30, 0.5 and 0.75 ml/litre) against mango fruit borer, Deanolis albizonalis, infesting mango cv. Gopalbhog. Fenpropathrin at 0.50 ml/litre gave the highest percent reduction in fruit damage compared to the control. Neem spray at 3.00 ml/litre gave the highest total cost, crop yield and gross returns while fenpropathrin at 0.75 ml/litre and DC tron plus at 4.0 ml/litre gave the highest net return and benefit:cost ratio, respectively.
