Abstract:

The bagworm, Cryptothelea crameri Westwood (Psychidae : Lepidoptera) is an
important pest of many ornamental, horticultural and forest plants in Bangladesh. The
larva feeds on young leaves and tender bark by making and living within a portable bag
of leaves, twigs, barks, spines, etc. The biology, host range, number of generations, and
seasonal abundance of the pest have been dealt with in this paper. Brachymeria sp.
(Braconidae: Hymenoptera) wasfound to parasitize its larva. The pestcould be collected
and destroyed by hand. It could also be controlled by the foliar application ofmalathion
(Malathion 57 EC) at 0.1% concentration.
