Abstract
One year survey observed 38 families consisting of 92 genera and 168 species on 25 aromatic and medicinal plant species belonging to 13 families; addition to 75 ornamental plant species from nine groups at Giza and Fayoum Governorates. Twenty-four species were recorded for the first time and a new phytoseiid mite species was observed. The population dynamics of mites and some sucking insect pests infesting six cultivars of rose (Rosa hybrida cv. Mabella Yellow, Sandra, Eiffel Tower, Huddly, Red Syntrex and White Queen Elizabeth) and Spearmint (Mentha viridis) beside the predaceous mite associated with them were recorded during two seasons (2006-2007) and (2007-2008).Description and measurements of all stages of the new phytoseiid mite, Euseius plumerii were presented. The two-spotted spider mite, Tetranychus urticae Koch was reared on the previous rose cultivars under conditions of (20, 25 and 30±2ºC) and 70±5% RH. The results documented that White Queen Elizabeth cultivar was one of the most favorable substrate for rearing T. urticae. Arabian Jasmine (Jasminum sambac) and Spearmint (M. viridis) also were used as substrates for rearing this pest under the same previous conditions. Rearing E. plumerii sp. n. and Neoseiulus barkeri (Hughes) on T. urticae immatures which infested leaves of rose (R. hybrida cv. Huddly) at the aforementioned conditions were done. The results asserted that 30ºC was the most suitable temperature accelerated the life cycle period, giving highly egg production and greatly prey consumption. The effectiveness of the endogenus predatory mite (E. plumerii sp. n.) and the predacious insect, Chrysoperla carnea (Stephens) to restrict T. urticae and some sucking insect pests; Macrosiphum rosae (Linnaeus), Frankliniella occidentalis (Pergande) and Bemisia tabaci (Gennadius) on rose plants (R. hybrida cv. Huddly) throughout two growing seasons were discussed. Addition to the population of those predators was also taking place.
