INTEGRATED MANAGEMENT OF BACTROCERA (DACUS) DORSALIS (HENDEL) IN MANGOES

Studies indicated that oriental fruitfly, Bactrocera dorsalis damage was reduced to 4.6 by harvesting fruits at physiological maturity stage as compared to 10% in fully ripe dropped fruits of Dashehari on June 22 and 8% to 4% in Bombay Green.
Methyl eugenol (0.2%) baited 4 traps/acre run for 18 weeks (2nd April to 30th July) gave reduction of 71.11% in damages of physiologically mature fruits of Dashehari and 71.15% in damages of fully ripe dropped fruits.
Highest trap catch of 233 males/week was between 18 June and 25 June.
Adult emergence was zero when fully mature larvae were pupated at 30 cm soil depth followed by 20, 65, 45 and 30% at 20, 10, 5 and 0 cm depths respectively indicating suitability of 30 cm depths for buring the damaged fruits.
Mango juice (5%) was most effective poison bait in reducing the damages to fruits (36.6% in physiologically mature and 17% in dropped fruits). Deltamethrin 0.002% gave 83.3% reduction in the damage of physiologically) mature and 78.80% in dropped fruits.
This was at par with fenvalerate 0.015% Biosteres dacussii (Cameron) was found to be the most important parasitoid.
