Abstract

        The present study was conducted in threepomegranate orchards at Manphalut area (north Assiut) and three orchards at Sidfa area, (south Assiut, Egypt) in order tosurvey phytophagous and predacious mites and insects inhabiting leaves ofpomegranate trees (Punica granatum L.) and explore their population densities  during the two successive years starting from November 2018 to October 2020. A total of twelve  species were recorded. Of these, two species are  phytophagous mites belonging to family Tenuipalpidae; four species are predacious mites (belonging to familyPhytoseiidae and to family Stigmaeidae)  and six species are predacious insects belonging to three families. The phytophagous and predacious mites and predacious insects recorded one annual peak during the two studied years. The phytophagous mites reached its peak number in July with an averageof629.50 and 696.00 individuals/25leaves in Manfalut area during the two successive years, respectively. While atSidfa area the peak number was recorded in August of both years with a mean numbers of 149.00 individuals in the first year and192.00 individuals/25 leaves in the second year. The predacious mites and insects recorded only one annual peak in August of both regions. Significant positive correlations were found among the temperature degrees (c°), phytophagous and predacious mites and predacious insects. Whereas, relative humidity has no effect.
