Impact of integrated fruit fly management module on the mango yield: An analysis through front line demonstrations

The Oriental fruit fly, Bactrocera dorsalis Hendel. is a major pest of mango 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 of mango 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 traditionaly 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.
