Management of Fruit Flies in Guava Through Male Annihilation Technique

Study on the management of fruit flies through male annihilation was undertaken on guava in five farmers’ orchards. Three orchards were installed with methyl eugenol traps @ 10, 20 and 40 traps/ ha. One orchard with 25 methyl eugenol traps/ ha as per the recommended package of practices (POP) of TNAU and without any trap was used as control. Significantly maximum catch of 178.83 males/ trap/ fortnight was caught with 40 traps, followed by the one with TNAU POP traps (100.25/ trap/ fortnight). The least fruit damage was (6.14%) in orchard where 40 traps were placed. TNAU POP traps placed orchard revealed the least fruit damage (10.71%).
