Abstract :

Eotetranychus hirsti Pritchard & Baker is one of the most important pests in Pol-e-Dokhtar, Lorestan provice, Iran, the area where fig is extensively cultivated. In this research we aimed to study the control effects of the following treatments on the pest: one time application of water, two times application of water, one time application of detergent, two times application of detergent and application of envidore, oberon and Floramite. The experiment was conducted based on a randomized complete block design with four replications. Correct mortality was measured and calculated on after 3, 7, 14 and 29 day from the time of application. Results showed significance differences among treatments in all times of measure. One time application of detergent showed 78.21%, 56.63%, 50.31% and 40.03% mortalities on 3, 7, 14 and 29 day from the time of application, respectively. The mortality of mite treated two times with detergent on day 29 was 92.54% which show not significantly different from those treated with acaricides. Moreover, one time application of water showed 47.32%, 25.33%, 23.37% and 19.77% mortalities of mite on 3, 7, 14 and 29 day from the time of application, respectively. The mortality of mites treated two times with water on 29 day was 62.21%. The population of the pest in trees treated with acaricides was about zero at all times of measure. The results of this research revealed that some more environment friendly methods, i.e. application of water or detergent, could decrease the population of fig mite. Therefore, considering their less effects on natural enemies of the pest, these methods could be recommended for integrated pest management.
