Prepare Orchard Fruit Fly Trap
The infestation of fruit fly is observed in fruit crops such as guava, sapota, mango, and others. The larvae emerges from the eggs laid by the fruit fly, enters in the fruit and feeds the internal contents. Sometimes, fruits also rot up due to the damage. The infested fruits do not matured and fall to the ground over a time. The yield and quality of fruits get deteriorated and, the market prices are not good or neither can be exported abroad. Clean cultivation, collection, and destruction of fallen fruits, frequent inter-culturing and installation of methyl eugenol ply wood blocks (2” x 2”) traps available in the market @16 per hectare at an equal distance on the trees are the major control measures. However, it is easy to prepare these kinds of traps at home with marginal cost.
Method for the preparation of traps: • Prepare a solution by taking methyl eugenol 20 ml, dichlorvos 76 EC or quinalphos 25 EC @ 2 to 3 drops and one liter of water. Collect a piece of sponge and dip into the solution. Keep the treated sponge in plastic jar having 2.5 cm diameter circular cut on both side. The trap is ready. • Install such 16 traps per hectare above 1.5 m from the ground on tree. • Instead of methyl eugenol, extract of black tulsi leaves (collect 500 g black tulsi leave in 1 lit of water and grind it with the help of grinder, the extract is ready) can also be utilize. • Collect & discard the catches of fruit fly every 2 to 3 days and recharge the sponge. • In addition, raise black tulsi plants around the orchard and spray dichlorvos 76 EC @ 10 ml or quinalphos 25 EC @ 20 ml per 10 liter of water periodically on them. • Poison bait can also be sprayed. For the preparation of poison bait, take 10 lit of water in bucket and add 500 jaggary or protein hydrolysate 300 g and keep it as such for some time. In this solution, add dichlorvos 76 EC 10 ml or quinalphos 25 EC 20 ml and steer them properly. Coarse spray of this solution on orchard boundaries as well as grass/shrubs and on trees during dusk period. Spray should be initiated at marble stage of fruits and continue at 15 days interval, 2-3 times.
