ABSTRACT The relationship between predaceous mites and citrus pests was studied in three different localities in Egypt ; Qualyobia ( Nile Valley ), Beheira (Coastal area) and EI-Tahreer province (new reclaimed lands). The phytoseiid mite species Euseius scutalis (Athias- Henriot) was the most commonly encountered predator associated with phytophagous mites and whiteflies, while the predatory cheyletid mite Cheletogenes ornatus Canestrini & Fanzago was the most abundant species associated with scale insects. |
