Genus Brevipalpus is considered one of the most important genera that belong to family Tenuipalpidae Berlese. In Egypt, Brevipalpus includes seven species solely, five of them are attacking citrus trees. B. phoenicis, B. californicus and B. noranae are the most dominant on Egyptian citrus. A pure culture of the three specieswere propagated on leaves of Common Navel orange variety. The mentioned species were studied at two different temperatures (25 and 30°C ± 2°C and 70 ± 5% R.H.). The obtained results enable us to conclude that between the three species of genus Brevipalpus, the citrus fruit most appropriate for the development of B. noranae, since the mite presents a reduced embryonic and post-embryonic period. The citrus fruit also provides the highest values of specific fertility, survival and of the intrinsic increase rate (rm), which indicates it as being a better suitable host for the mite which provide B. noranae to establish and rapid spread.
