Abstract
Population Fluctuation of The Citrus Red Mite Panonychus citri (McGregor) on Some Citrus Species at Giza, Egypt
Highlights
The citrus is one of the most important fruits in the world
This study aims to throw more light on the population fluctuation of P. citri on three citrus species during two successive years, determine the relation between Temperature, relative humidity and population
Experimental design: The study was conducted on citrus species namely Lemon (Citrus limon L.), Sweet Orange and naval Orange (Citrus sendonensis L.) in Abo-Galeb region at Giza
Summary
The citrus is one of the most important fruits in the world. In Egypt, the cultivated area is estimated by 518,694 Fadden produced 3,980,151 ton, average produced 9.54 ton per Fadden (In 2012). The citrus red mite, Panonychus citri (McGregor) (Acari: Tetranychidae) is one of the most important pest that attacks citrus trees and distributed worldwide This mite attacks more than 80 species of plants, including citrus, rose, almond, pear, castor bean, and several broadleaf evergreen ornamentals (Gotoh & Kubota 1997; Bolland et al, 1998; Zhang, 2003; Childers et al, 2007). In Alabama, P. citri is an important pest of Satsuma mandarin (Citrus unshiu Marcovitch) (English & Turnipseed 1941, Fadamiro et al, 2007, 2008). This mite species prefers sweet oranges as a host plant followed by lemon, clementine and hybrids that affected (Izquierdo et al, 2002). This study aims to throw more light on the population fluctuation of P. citri on three citrus species during two successive years, determine the relation between Temperature, relative humidity and population
