Kadam (Anthocephalus chinensis (Lam.) Rich ex. Walp.}, a fast growing
multipurpose tree species, is grown in the homesteads and planted in the forest areas of
Bangladesh. The plantations of this species often suffer from the attack of the defoliator,
Arthroschista (=Margaronia) hilaralis Walker (Pyralidae : Lepidoptera). This paper
describes distribution, host plants, nature and impact of damage, life history, number of
generation, population fluctuation, natural enemies and management of the pest. The
pest completes its life cycle within 23.0 + 3.0 days. It has 9-10 generations in a year.
Younger trees, usually 2-5 years of age, were found most heavily infested. The peak
infestation occurred during August-September. Two parasites, Apanteles balteatea Lal.
(Braconidae : Hymenoptera) and Brachytneria lasus Walk. (Chalcididae: Hymenoptera),
caused a mortality of about 40% of the pest population. Application of Thuricide
(Bacillus thnringiensis) 40 WP or Malathion (malathion) 57 EC @ 0.1% concentration was
effective in controlling severe infestation. Hand collection and destruction at the initial
stage of infestation could suppress and provision of overhead orside shade for the tree
could prevent the attack of this pest
