  • The Predatory Mite (Acari, Parasitiformes: Mesostigmata (Gamasina); Acariformes: Prostigmata) Community in Strawberry Agrocenosis
    Acta Universitatis Latviensis, Biology, 2004, Vol. 676, pp. 87–95 The predatory mite (Acari, Parasitiformes: Mesostigmata (Gamasina); Acariformes: Prostigmata) community in strawberry agrocenosis Valentîna Petrova*, Ineta Salmane, Zigrîda Çudare Institute of Biology, University of Latvia, Miera 3, Salaspils LV-2169, Latvia *Corresponding author, E-mail: [email protected]. Abstract Altogether 37 predatory mite species from 14 families (Parasitiformes and Acariformes) were collected using leaf sampling and pit-fall trapping in strawberry fi elds (1997 - 2001). Thirty- six were recorded on strawberries for the fi rst time in Latvia. Two species, Paragarmania mali (Oud.) (Aceosejidae) and Eugamasus crassitarsis (Hal.) (Parasitidae) were new for the fauna of Latvia. The most abundant predatory mite families (species) collected from strawberry leaves were Phytoseiidae (Amblyseius cucumeris Oud., A. aurescens A.-H., A. bicaudus Wainst., A. herbarius Wainst.) and Anystidae (Anystis baccarum L.); from pit-fall traps – Parasitidae (Poecilochirus necrophori Vitz. and Parasitus lunaris Berl.), Aceosejidae (Leioseius semiscissus Berl.) and Macrochelidae (Macrocheles glaber Müll). Key words: agrocenosis, diversity, predatory mites, strawberry. Introduction Predatory mites play an important ecological role in terrestrial ecosystems and they are increasingly being used in management for biocontrol of pest mites, thrips and nematodes (Easterbrook 1992; Wright, Chambers 1994; Croft et al. 1998; Cuthbertson et al. 2003). Many of these mites have a major infl uence on nutrient cycling, as they are predators on other arthropods (Santos 1985; Karg 1993; Koehler 1999). In total, investigations of mite fauna in Latvia were made by Grube (1859), who found 28 species, Eglītis (1954) – 50 species, Kuznetsov and Petrov (1984) – 85 species, Lapiņa (1988) – 207 species, and Salmane (2001) – 247 species.

In Europe, it is an indige- nous species, commonly found on various plants, including conifers. The present study examined whether A. andersoni can develop and reproduce while feeding on two key pests of ornamental coniferous plants, i.e., Oligonychus ununguis (Jacobi) and Pentamerismus taxi (Haller). Pinus sylvestris L. pollen was also tested as an alternative food source for the predator. Both prey species and pine pollen were suitable food sources for A. andersoni. Although higher values of population parameters Citation: Puchalska, E.; were observed when the predator fed on mites compared to the pollen alternative, we conclude that Zagrodzki, S.K.; Kozak, M.; pine pollen may provide adequate sustenance for A.
