Abstract EN

A study conducted at Ninavah province, Iraq, during the years 1997 and 1998 revealed a non significant correlation between environmental conditions (temperature, relative humidity) and the average infestation of grape clusters or infested grape berries, and a significant and positive correlation between the number of grape moth larvae and relative humidity.

The distribution of infestation between grape clusters in a tree was at random and grouped within the grape berries in a cluster.

The adults appeared during middle April, 1998 and laid on the average 61.2 eggs/female.

The average incubation period of eggs, larval period, pupal period, the adult stage for males and females were 12.3, 25.0, 8.0 and 11 days, respectively.

The moth had 4 generations per year.
