خلاصه مقاله:
The two–spotted spider mite Tetranychus urticae Koch is one of the most important pests of agricultural crops over the world, infesting a wide range of plants including some economically important crops. An investigation was carried out to study the life table parameters of five populations of T. urticae including Urima, Dashtnase, Faryman, Razkan and Tehran under laboratory conditions at ۲۷ °C, ۶۰% RH and ۱۶ L: ۸ D h on Malus domestica Borkh leaves. There was a significant difference in developmental time of T. urticae among tested populations. The total survival rate of T. urticae ranged from ۷۶% to ۸۱%. The adult longevities were significantly different. The adult longevity of the Faryman and Dashtnase populations were different from the Razkan population. Total fecundity of the Urima, Razkan and Tehran populations were higher than that observed for the other tested populations. The highest value of R۰ was in the Urima and Dashtnase populations and the lowest one was in the Faryman population. The r values of the Dashtnase (۰.۲۴۸ day-۱) and Urima populations (۰.۲۰۰ day-۱) were significantly higher in comparison to the Faryman population (۰.۱۲۴ day-۱). The observed variation of the two-spotted spider mite collected from different localities showed that ecological factors such as geographical separation can influence the life table parameters of phytophagous organism.
