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
