- Sanitation should be maintained in orchard.
- Harvest the fruits before full ripening to prevent the attack of fruit flies.
- Collection and disposal of all the fallen fruits is also recommended during the fruiting season. Collection of fallen fruit in polythene bag and tide firmly for 4-5 days can effectively kill the maggots in the fruits. Avoid the dumping of fallen fruits in soil.
- Installation of methyl eugenol impregnated wooden plywood block based fruit fly trap (‘Nauroji Stonehouse’/Mineral water bottle trap) @ 10 traps/ha and should be changed or replenished once in 2-3 months.
- Conservation and augmentation of naturally occurring parasitoids and predators at fruiting stage.
Method of Plastic Trap Preparation :
- Insert hand inside the plastic trap from top towards bottom and press equally to all sides. Close the lower portion of the trap (Fig. B1).
- Remove ready plywood block from polythene bag and insert small iron or nylon thread inside the small hole made on top flap of trap (Fig. B2).
- Press four side of trap and make triangle shape on top of the trap (Fig. B3).
- Elongate the thread from the top hole of trap and make a knot near flap hole to fix the block inside the trap in middle portion. This required to avoid slipping of block (Fig. B4).
- Close the top triangular part of trap by flap lock and hang out on tree branch about 5-6 feet above ground level for monitoring or mass trapping of fruit fly (Fig. B5).
Method of Plastic Bottle Trap Preparation :
- Use 1 litre water capacity plastic water bottle fro trap preparation (Fig. C1).
- Make 2-2.5 cm (1 inch) size hole on four side of bottle from top 10-12 cm (3 inch) below cap. Also, cut 3-4 cm (1.5 inch) size bottom portion of bottle and keep aside (Fig. C2).
- Remove bottle cap and make small hole on it so that small iron or plastic thread can be inserted through it (Fig. C3).
- Remove ready plywood block from polythene bag and insert the block inside bottle from open bottom portion. Elongate the small iron or nylon thread towards top and insert in small hole made on bottle cap. Make a knot near hole to fix the block inside the trap in middle portion. This required to avoid slipping of block (Fig. C4).
- Fix the bottom portion of bottle with inverted 3-4 cm size already cut potion (Fig. C5).
- Hang out the trap on tree branch about 5-6 feet above ground level for monitoring or mass trapping of fruit fly (Fig. C6)
