Host plant resistance mechanism for fruit fly in mango has been studied.

Bioecology of sapota seed borer, Trymalitis margareas was studied and an IPM involving time bound application of botanicals and chemicals was developed.

IPM of Mango fruit fly, Bactrocera dorsalis (Hendel)

An ecofriendly integrated management of  B. dorsalis in mango has been standardized, which is mentioned below

	45 days before harvest,  the following precautions need to be taken
	Destroy all fallen fruits at weekly intervals
	Install six methyl eugenol plywood traps per acre
	Plough the soil at the tree basin at frequent intervals.
	Three weeks before the harvest, spray decamethrin 2.8 EC @ 0.5 ml/l + Azadirachtin (0.3%) 2 ml/lt and take up timely harvest.
	If fruit fly is very serious (> 5/Surveillance trap), give bait sprays on the tree trunks at weekly interval:  (Bait spray is prepared by mixing 100g of jaggery in one litre of water to which 2 mL  of  deltamethrin (2.8 EC) is added).
	The harvested fruits may be treated with hot water for 1 hour at  48oC.

IPM of mango stone weevil, Sternochetus mangiferae (Fabricius)

	ollect and destroy all fallen fruits at weekly intervals till harvest.
	Clean, using old brooms junctions of branches on the trunk prior to flowering (October).
	Spray Acephate 75 SP @1.5 g/l when the fruits are of lime size (2.5 – 4 cm diameter). This spray should be followed by decamethrin 2.8 EC @ 1ml/l after two to three weeks.
	Destroy all leftover seeds in the orchard after harvest and also in the processing industry.
