Abstract

Brown-tail moth, (Euproctis chrysoruhoea) is a polyphagous defoliator, attacking forest as well as fruit trees, and has become a public health hazard owing to the irritant minute hairs of the larvae, pupa and female moths. Contarary to the previous reports, our study demonstrated that E.chrysoruhoea is actually the prevalent defoliater moth in Arasbaran forests. According to our three year studies in feild and laboratory conditions, adult moth emerge at the end of spring and begin to lay eggs, after mating. Elongate egg masses were laid on lower surface of leaves and covered with the brown hairs of abdominal tuft "tail" of female. The eggs after incubation period (15-20 days) hatch from early August and first instar larve feed on upper paranchyma of hosts leaves. The larvae molt twice as they feed gregariously and gradually construct their winter nest in the same
hosts which they feed on. There are between 150 to 400 3th instar larvae in any single overwintering nest. In the following spring they restart feeding and the larvae move away from the nests and often become solitary. They spin silken cocoons between the leaves, either singly or in groups and
pupate. About 20 days after pupation, adults emerge from the end of June. Thus there is only a single generation in a year. Associated natural enemies in Arasbaran included: two predator spiders, five parasitoid wasps, a dipterous parasitoid, one kind of parasitoid nematode and an unknown entomopathogenic agent (probably a fungi). Natural enemies have important role in lowering pest population.
