Abstract

The two spotted spider mite, Tetranychus arabicus Attiah and its predatory mite, Phytoseius fiaitimus Ribaga were studied on sultani fig variety in sohage Governorate under the prevailing weather condition for two successive years (1995-1996). T.arabicus had one annual peak in July 1995 and in June 1996, while the predator mite, P.finitimus had one annual peak in August in the two studied years. The average minimum temperature and the mean temperature had a highly significant correla­tion with T.arabicus, while the average maximum temperature had a posi­tive significant correlation in this respect. However, a negative correla­tion with relative humidity was recorded. P.finitimus had a highly positive correlation with T.arabicus.
