The study was carried out to devise moth effective and economical integrated pest management strategy against fruit flies in guava orchards. The experiment was laid out in randomized complete block design with three replication and eight treatments including the control. Hoeing under the tree canopy at 15 days interval along with collection of fallen fruits and burying deep in the soil and spray of spinosad was found to be most effective reducing the average fruit fly infestation to 6% and 6.3% for the year 2013 and 2014 respectively with cost benefit ratio of 1: 14.7, followed by the of hoeing and sanitation alongwith the spray Diptrex 80% WP @ 150 gm / 100 liter of water (CBR= 1: 14.85). Hoeing under tree canopy alone proved to be least effective with average fruit fly infestation 16.67% and 15.85% for the year 2013 and 2014 respectively with lowest CBR.
