The document discusses the mango fruit fly (Bactrocera dorsalis), outlining its biology and lifecycle, including egg laying, larval feeding, and pupation. It also details integrated pest management (IPM) practices, including cultural, trapping, chemical, and biological control methods to mitigate the pest's impact on mango crops. Key strategies include disposing of infested fruits, using bait traps, and applying specific insecticides prior to fruit ripening.

1. IMPORTANCE AND IPM PRACTICES OF MANGO FRUITFLY
MANGO FRUITFLY,Bactrocera dorsalis
Tephritidae
Mango fruit fly (Bactrocera dorsalis) biology: Eggs are laid inside mango fruit, larvae
feed on pulp, pupae form inside fruit or in soil, and adults emerge to mate and restart
the cycle.
IPM practices:
Cultural Control
1. Collect and dispose infested fruits in a pit.
2. Summer ploughing to expose pupae.
Trapping
1.Prepare bait with methyl eugenol 1% solution + Malathion 0.1% (10ml/trap, 25
traps/ha).
Chemical Control
1. Bait spray: combine insecticide (fenthion, malathion, dimethoate, or carbaryl) with
molasses/jaggery (10g/l).
2. Spray fenthion 100 EC (2ml/l) or Malathion 50 EC (2ml/l) before fruit ripening.
Biological Control
1. Release natural enemies: Opius compensates and Spalangia philippines.
