NEGM1, FAHAD J. ALATAWI & YOUSIF N. ALDRYHIM Department of Plant Protection, College of Food & Agriculture Sciences, King Saud University, Riyadh 11451, P.O. Box 2460, Saudi Arabia 1Corresponding author. E-mail: [email protected] Abstract Eight species of phytoseiid mites are reported from date palm orchards in Saudi Arabia. Seven of them were first records for this country: Neoseiulus bicaudus (Wainstein), N. conterminus (Kolodochka), N. makuwa (Ehara), N. rambami (Swirski & Amitai), Proprioseiopsis asetus (Chant), P. messor (Wainstein), P. ovatus (Garman). Neoseiulus makuwa and P. asetus are recorded from the Middle East and North Africa for the first time. One new species is described from Bermuda grass, Neoseiu- lus saudiensis n. sp. The new species is most similar to Neoseiulus alpinus (Schweizer) and N. marginatus (Wainstein). A key for identification of the included species is provided. Key words: Acari, Mesostigmata, Phytoseiidae, biological control, predatory mites, Neoseiulus saudiensis, Saudi Arabia. Introduction The predatory mite family Phytoseiidae contains most of the species presently used as biological control agents of mite pests (Kostiainen & Hoy, 1996; McMurtry & Croft, 1997). The fauna of Phytoseiidae in Saudi Arabia is very poorly known, with only ten species previously recorded (Dabbour & Abdel-Aziz, 1982; Al-Shammery, 2010; Al- Atawi, 2011a,b; Fouly & Al-Rehiayani, 2011). Projects are underway to identify the fauna of phytoseiid mites in Saudi Arabia and select the species that may have potential as biological control agents.

  • 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.

  • A New Species of Predatory Mite, Amblyseius (Acarina: Phytoseiidae) from Stored Coffee Berries
    J. bio-sci. 14: 39-41, 2006 ISSN 1023-8654 A NEW SPECIES OF PREDATORY MITE, AMBLYSEIUS (ACARINA: PHYTOSEIIDAE) FROM STORED COFFEE BERRIES Mary Anithalatha Sadanandan P G and Research Department of Zoology, Malabar Christian College, Calicut, Kerala 0495 2760268 Abstract A new species of predatory mite of the family Phytoseiidae viz., Amblyseius (Amblyseius) coffeae sp. nov. is described from stored coffee berries. Key words: Predatory mite, Phytoseiidae, Amblyseius, new species. Introduction Predatory mites constitute a highly significant beneficial group on account of their vital role in the maintenance of pest population below the economic injury level. The species of Phytoseiidae are potentially important as a biotic factor in the control of phytophagous mites (Ewing 1914). Mass multiplication methods have been developed to use these predators in commercial scale on a variety of crops (Lo et al. 1979, Krishnamoorty 1982). Phytoseiidae contain 168 species under 12 genera (Gupta and Arun Gupta 1999). However, the reports on occurrence of new species are scanty from peninsular India. Hence a systematic survey was undertaken to unravel the occurrence of new species of Phytoseiidae from various districts of Kerala. The present new species was collected during this survey. The occurrence of phytoseiids in stored products is a very rare phenomenon, though isolated examples exists for the occurrence of members of Amblyseius and Neoseiulus in stored grains (Hughes 1976, Smiley 1984). Materials and Methods The predatory mite fauna harbouring on various stored commodities were collected by making extensive surveys in Kerala. Random samples of 100gms were collected in separate polythene bags and brought to the laboratory.

A comprehensive taxonomic review of the genus and species was carried out by Mesa et al. (2009), which lists all suspected junior synonyms of R. indica, including Raoiella camur (Chaudhri and Akbar), Raoiella empedos (Chaudhri and Akbar), Raoiella obelias (Hasan and Akbar), Raoiella pandanae (Mohanasundaram), Raoiella phoenica (Meyer) and Raoiella rahii (Akbar and Chaudhri). The review also highlighted synonymy with Rarosiella cocosae found on coconut in the Philippines.
