Eriophyid Mite (Aceria litchi)
:
Both nymphs and adults infest leaves. The adult
mites are small white coloured insects which live
on the under surface of the leaves. The mites
puncture and lacerate the tissues of the leaf
and suck the cell sap. They attack the young leaves
causing hairy, blister-like galls on the upperside
of the leaves. The leaves become thickened, wrinkled
and distorted. The leaves may ultimately fall
off. The mites also attack and cause malformation
of inflorescence. The attack is much severe on
'Bombai', 'China' and 'Kasba' varieties.
Control : Pruning and destroying the infested
plant parts helps to check the mite population.
Sprays of insecticides like Kelthane (0.12%) or
Dimethoate (1ml/litre) is recommended for effective
control of mites.
Bark eating caterpillar (Indarbela
quadrinotata; Indarbela tetraonis) :
The caterpillars feed on the bark of the tree
during night. They bore inside the trunk or main
stems and eat through the bark into the wood.
The affected portion is covered with large silken
webs. In case of severe infestation, sap movement
is affected due to which the tree fails to flower.
Control :
A small metal wire is inserted into the hole to
kill the caterpillar. The holes are then plugged
with cotton wool soaked in chloroform, formalin
or petrol and sealed with mud.
