Abstract

The Heart moth had outbreaks in forest regions of Chaharmahal and Bakhtiari province in recent years. During, 2011-2012 biologicol aspects of this moth were studied in field and laboratory conditions. For this purpose from the first of February to end of June in this province twenty trees were selected and eggs, different larval stages and pupa on four twigs in four geographical directions were surveyed weekly. The adults emergence and flypeak were determined by light trap and adult fly peak were recorded. Surveys were conducted to pest owerwintering determination The results indicated that different larval stages feed on buds and leaf. The larval longevity were 22± .26 and 29± .14 days and pupal longevity were 8± .3 and 11± .16 days in laboratory and field condition respectively. The adult longevity were 7± .2 and 9±.11. Then the adults mated and females laid eggs in group on the end of top twigs under scales that caused by females. This pest have one generation per year and owerwintered as egg. The moth were idendified by Dr. abai in last years.
