Abstract


The Oriental fruit fly, Bactrocera dorsalis Hendel. is a major pest ofmango in India, which causes significant
loss of marketable yield. A study was conducted to assess the impact of the integrated pest management (IPM) module
involving crop sanitation, bait sprays and male annihilation technique (MAT) using methyl eugenol as lure developed by
ICAR-Indian Institute of Horticultural Research, Bengaluru for control ofmango fruit fly through field demonstrations during
2012-13, 2013-14 and 2014-15. It was evident that demo orchards recorded lower fruit fly infestation (8.66 %) as against 38.13
per cent in non-adapted orchards. Anadvantage average yield increase of 51.51 per cent was recorded under demonstration
orchards, as compared to farmers traditional way.Wide yield gaps were observed during all the years, ranging from 2.14 ton/
ha to 3.06 ton/ha. On three years average basis, technology gap of total 30 demonstrations was observed as 2.58 ton per
hectare. The benefit-cost ratio was 4.71 and 4.09 in 2014-15 and 2012-13, respectively.
