Comparative population fluctuation of fig spider mite (Eotetranychus hirsti) on fig varieties in Saveh region. Journal of Entomological Society of Iran, 22: 49-61.
Abstract
Fig spider mite (Eotetranychus hirsti) is a serious pest of figs in Iran, other fig growing areas in the world. Population fluctuation (eggs and active stages) of fig spider mite have been investigated on eleven fig varieties include: yellow indigenous, Saveh yellow and Black indigenous, Varamine black, Onion yellow, wild fig, Garmsar Morabai, Siljerd yellow and American, in Saveh region during 2000-2001. Eggs and active stages of the mite were counted using a four square centimeter quadrate placed on the lower surface of host leaf. A randomized block design with four replication and a fort nightly interval sampling was used (May to mid Nov.) Analysis of variance were carried out on collected data and differences of mite population observed by Duncan’s multiple range test on fig varieties. Maximum mean of eggs 6.08,5.05 and active stages 31.87, 27.62 recorded for Wild fig variety in both years which statistically found in the group of (a) and was more susceptible in comparison to other varieties followed by Garmsar Morabai (ab) and Siljerd yellow (be). Whereas, minimum of 0.002 and 0.02 egg were recorded on Varamine black in both years and for active stages 0.032 and 0.36 mite recorded on Yellow indigenous and Varamin black on both years respectively.
