Life history of the predatory mite, Cydnodromella negevi and the effect of nutrition on its biology (Acari: Phytoseiidae)

Effect of different eriophyid and tetranychid mango mite species on development, longevity, fecundity and predation ofTyphlodromus mangiferusZaher and El-Brolossy (Acari: Phytoseiidae)

“…It seems that motile stages of eriophyid mango mite species are more suitable as main prey than nymphs of tetranychids. A high reproduction rate was also recorded on eriophyid mites as prey (Abou-Awad and El-Banhawy 1986; Reda and El-Bagoury 1986;Abou-Awad et al 1989;Momen 1993;Momen and Hussein 1999;Abou -Elela 2003;Metwally et al 2005). On the other hand, the presence of an alternative tetranychid as a secondary prey should help phytoseiids to survive the period of main prey scarcity and 394 B.A.…”

“…Knowledge of the natural value of different prey, especially three specialised mango eriophyids, for T. mangiferus could be of importance not only for mass rearing of the mite, but also for a better understanding of its population dynamics in the field. However, the reproduction potential of some phytoseiid species is highest on eriophyoids (Chant 1959;El-Banhawy 1974;El-Bagoury and Nasr 1984;Abou-Awad and El-Banhawy 1986;Abou-Awad et al 1989;Momen 1993Momen , 1999Abou-Elella 2003;Metwally et al 2005), wherever in some cases spider mites alone are unsuitable for development unless supplementary foods are present (Overmeer 1985;Abou-Setta and Childers 1987;Ferragut et al 1987;Abou-Setta and Childers 1989). In our study, developmental rate, generation, adult longevity, fecundity and life table parameters of T. mangiferus were determined on four eriophyid and tetranychid prey species at different temperatures and relative humidities and used as an index for their nutritional value.…”

Typhlodromips swirskii (Acari: Phytoseiidae): A Predator of Eriophyid and Tetranychid Mango Mites in Egypt

“…The preference of the eriophyid mites as prey for the phytoseiid mites compared to the tetranychid prey was reported by several workers (Abou-Awad et .al., 1989;Momen and El-Sawy, 1993;Momen, 1999, Rasmy et al, 2002 and Abou-Awad et al, 2005. In addition, the daily rate of feeding capacity of the predatory females positively increased with increasing temperature degree joint with decreasing humidity, whereas the predatory immatures displayed opposite trend.…”

Incidence of predatory phytoseiid mites in Saudi Arabia: new records and a key to the Saudi Arabian species (Acari: Mesostigmata: Gamasina)

“…Cydnoseius negevi immature females consumed 20.4 prey of O. afrasiaticus while they consuming 27 individuals of Eutetranychus orientalis and 34 of T. urticae, respectively (Abou-Awad et al 1989), and 166.4 individuals of E. ficus and 133.1 eggs of T. urticae, respectively (Abou-Awad et al 1998). The larger consumption of E. ficus and T. urticae is related to the smaller size of the prey species/stages.…”

“…Cydnoseius negevi (Swirski and Amitai 1961) and Neoseiulus barkeri Hughes 1948 (Acari: Phytoseiidae) are common species found in the Middle East (Abou-Awad et al 1989, Fouly and El-Laithy 1992, Abou-Awad et al 1998, Palevsky et al 2009, Hountondji et al 2010, Jafari et al 2010. The natural occurrence of these predators was reported in datepalm orchards at different provinces of Saudi Arabia (Negm et al 2012a, b).…”
