The phytoseiid mitePhytoseius plumifer as a predator of the eriophyid miteAceria ficus [Acarina]

The exotic predaceous mite, Phytoseiulus persimilis Athias-Henriot and the 2 native ones Phytoseius finitirnus Ribaga and Amblyseius gossipi Elbadry were released on greenhouse cucumber plants in Egypt to examine their efficiency to control the twospotted spider mite Tetranychus urticae Koch. P. persimilis proved to be sufficiently effective for the twospotted spider mite control under greenhouse conditions in Egypt. The 2 before-mentioned native predators were lost soon after release in the greenhouse although they are key mite predators on outdoor crops in this area. KEY-WORDS : Phytoseiulus persimilis, Phytoseius finitimus, Amblyseius gossipi, Tetranychus urticae, greenhouse, release.Chemical control is still the primary method used to control the twospotted spider mite Tetranychus urticae Koch on vegetables grown in greenhouses in Egypt. Phytotoxicity and the loss of efficacy as a result of resistant pest populations are the major problems encountered. Moreover, it was observed that plants are more damaged from the excessive application of pesticides than they are by the pests themselves.Considerable advancements have been achieved in biological control of mites infesting greenhouse crops in different areas through the release of the predatory mites Phytoseiulus persimilis Athias-Henriot and P. macropilis (Banks) (Hamlen & Lindquist, 1981 ;Osborne et al., 1985; Vacante & Nucifora, 1987). In the present study, P. persimilis (OP-resistant strain, originally from GDR) was introduced into Egypt and released on greenhouse cucumber.For comparison, the use of the 2 native predaceous mites Phytoseius finitimus Ribaga and Amblyseius gossipi EIbadry for mite control was also evaluated. The last 2 predators were found to be effective on outdoor crops (Rasmy & Elbanhawy, 1974 ; Rasmy, 1977). MATERIALS AND METHODSP. persimilis was mass-reared on the twospotted spider mite maintained on bean plants. P.finitimus and A. gossipi were taken from a colony fed pollen grains of castor bean Ricinus communis L. P. persimilis was released on a bed of 200 plants, while another bed of an equal number of plants was left as a check. For comparative studies, each of the other 2 predators was released on a group of 100 plants. Release of predators was carried out at a rate of 10 predators per plant at the 1st sign of the twospotted spider mite damage, when slight discoloration of leaves was observed. The predators were introduced on the remarkably infested leaves.For assessing mite populations, 5 leaves of each treatment were investigated at weekly intervals and the number of mites was recorded. When P.finitimus and A. gossipi were not encountered on leaf samples, a supplementary release with these 2 predators was conducted after 2 weeks of the 1 st release to ensure their establishment. RESULTS AND DISCUSSIONAlthough the 2 native predators P.finitimus and A. gossipi are the key mite predators on several outdoor crops in Egypt, both predators did not develop successfully under greenhouse conditions. In fact they were lost soon after rele...

“…This species is reported in Mediterranean basin and has been observed in vineyards (Minarro and Kreiter 2012). Phytoseius finitimus is a natural enemy of Panonychus ulmi (Koch) (Duso and Moretto 1994), and eriophyid mites: Aceria ficus (Rasmy and El-Banhawy 1974), it can also feed on pollen (Rasmy and El-Banhawy 1975).…”

“…On hollyhock and cotton pollen or sweet potato leaves, the immatures failed to develop to adulthood. Rasmy and Elbanhawy (1974) studied the effect of the eriophyid mite Aceria ficus Cotte, the tetranychid mite Tetranychus arabicus Attiah and castor-oil pollen on the development and fecundity of P. plumifer. They found that A. ficus was a more favourable prey for the predators than T. arabicus, and a doubling time (DT) of 3.43 days.…”

“…The predatory mite Phytoseius plumifer (Canestrini and Fanzago) is an important generalist indigenous predator of tetranychid and eriophyid mites on various crops in Iran (Kamali et al, 2001;Hajizadeh et al, 2002;Nadimi et al, 2009) as well as in other countries (Rasmy and Elbanhawy, 1974;Castagnoli and Liguori, 1985). Knowledge of the nutritional value of different plant pollens for P. plumifer is not only important for mass rearing of the mite, but also for a better understanding of its population dynamics in the field.…”
