Abstract

Samples of cucumber, squash, kidney-bean and broad bean plants from different localities of Kaliobia and Giza governorates were collectd weekly and examined for mites throughout one year. The collected phy­tophagous mite species were; Tetranychus urticae Koch, Brevipalpus cal­ifornicus (Banks), Tydeus californica and Tyrophagus putrescentiae Schrank. The tetranychid mite, T.urticae was the most dominant phy­tophagous species found on the crops. On kidney-bean, the highest in­festation was recorded in September and November (88 and 114 indi­viduals/leaf, respectively), while on cucumber, the highest infestation occurred during May, June and July, where the average number of mites were (38, 176.3 and 50.7 individuals/leaf, respectively). The predaceous mites surveyed were Euseius scutalis (Athias­Henriot) A.gossipi El-Badry), Amblyseius swirskii (Athias-l-ienriot), Agistemus vulgaris Gomaa and Raphignathus sp. E.scutalis was the most abundant predaceous mites on cucumber and kidney bean.
