Bark eating caterpillar- a threat in Orchard crops
The bark eating caterpillar is damaging to the horticultural crops such as pomegranate, guava, mango, drumstick, ber, mango, aonla etc.
The caterpillar feeds inside the stem and bark by making holes on the trunk.
Caterpillars hiding in-side the hole during daytime and feed the green matter of the bark during night hours.
Webs & excreta of the caterpillars are clearly visible on the stem/branch. Sometimes, infested branches are also broken down due to the wind.
Generally, the infestation is much more in older trees.
Maintain clean & neat orchard and do regular pruning of the trees.
Cut & destroy the heavily infested branches by this pest.
Remove the webs made by the caterpillars from the tree trunk and branches.
Insert the iron spoke in the hole made by the caterpillar and kill it.
Pour the solution (one liter kerosene + 100 g soap powder + 7 liter water) as per the requirement in the holes and seal with the cow dung/ clay soil.
Give this kind of treatment twice in a year.
Also spray any insecticides on tree trunk after removing webs on tree trunk. Do twice in a year
