Abstract: 

Leaf feeder moth (Erannis defoliaria Clereck) recognized & reported for the first time in the west part of Mazandaran forest of Iran (1998). In this research a two hectare sample plot from a compartment of hornbeam trees selected and from infected trees, 10 trees signed for sampling. Where as the female moths are wingless & for laying eggs, raise from tree trunks, plastic band (wide: 30cm) with Tengel food adhesive used for capturing them. By counting the eggs in the female insect’s body, number of larva on the tree trunks and number of pupa in a square meter below the trees and also percentage of mortality, life table of this moth obtained. The male fly from in late autumn with a few stragglers turning up until in mid January. Again, the females are wingless. The females of this pest crawl up the trunk and mating with the males in sunset. Then female lays eggs in the crevice on the trunk or under the moss grown on trees. The eggs after over wintering in early April are hatching and the larva move geometrically and reach themselves to shoot and leaves and feed them severely, larva start to pupate under soil surface in early May. In early June all of them change to the brownish pupa. The stage of pupate lasts until the mid November. According to studies this pest has one generation per year. Erannis defoliaria or mottled umber attacks to most of trees exception Alder, Oak and Wild kaki. Also That is Observed natural enemis such as Bracon SP. And Chaetinella SP and Parus major feed this pest.
