3. Fruit Fly (Dacus dorsalis)
• At fruit maturity fruits are attacked by fruit
fly. On hatching maggots bore into the fruits
and feed on the pulp. The infested fruits
become unfit for human consumption.
• Management:
• It is difficult to control the fruit flies, once
they enter the fruits. One can reduce the
attack.
• (i) Hoeing of the tree basins should be done
to expose the pupae to their natural
enemies.
• (ii) Collect the infected fruits and dump in
deep pits.
• (iii) To repel the fruit fly spray Thiodan 35E
(endosulphan) @ 2 ml/L. of water in first
week of February and repeat the spray in the
last week of February or spray Sevin 50 WP
(carbaryl) @ 2 g/L. of water twice.
4. Bark Eating Caterpillar (Inderbela
Quadrinota):
Damage
• Bark eating caterpillars cause
huge damage to loquat trees.
• Caterpillars feed on the bark
and make tunnels in the trunk.
Due to tunnelling, girdling is
caused, which may kill the
plant.
• Management:
• Clear the holes/tunnels with
wire, inject kerosene oil or
chloropyriphos solution 50: 50
water.
