A Novel Trade-Off for Batesian Mimics Running Title
Out of the frying pan and into the fire: A novel trade-off for Batesian mimics Running title: Salticids that mimic ants and get eaten by ant specialists Ximena J. Nelson*†, Daiqin Li§ and Robert R. Jackson† *Department of Psychology, Animal Behaviour Laboratory, Macquarie University, Sydney, NSW 2109, Australia Email: [email protected] Phone: 61-2-98509232 Fax: 61-2-98509231 §Department of Biological Sciences, National University of Singapore, Singapore †School of Biological Sciences, University of Canterbury, Private Bag 4800, Christchurch, New Zealand Key words: Ants, Batesian mimicry, myrmecophagy, predation, spiders, trade-off Abstract A mimicry system was investigated in which the models were ants (Formicidae) and both the mimics and the predators were jumping spiders (Salticidae). By using motionless lures in simultaneous-presentation prey-choice tests, how the predators respond specifically to the static appearance of ants and ant mimics was determined. These findings suggest a rarely considered adaptive trade-off for Batesian mimics of ants. Mimicry may be advantageous when it deceives ant-averse potential predators, but disadvantageous in encounters with ant- eating specialists. Nine myrmecophagic (ant-eating) species (from Africa, Asia, Australia and North America) and one araneophagic (spider-eating) species (Portia fimbriata from Queensland) were tested with ants (5 species), with myrmecomorphic (ant-like) salticids (6 species of Myrmarachne) and with non-ant-like prey (dipterans and ordinary salticids). The araneophagic salticid chose an ordinary salticid and chose flies significantly more often than ants. P. fimbriata also chose the ordinary salticid and chose flies significantly more often than myrmecomorphic salticids. However, there was no significant difference in how P. -
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. -

Risk of Exposure of a Selected Rural Population in South Poland to Allergenic Mites
Experimental and Applied Acarology https://doi.org/10.1007/s10493-019-00355-7 Risk of exposure of a selected rural population in South Poland to allergenic mites. Part II: acarofauna of farm buildings Krzysztof Solarz1 · Celina Pająk2 Received: 5 September 2018 / Accepted: 27 February 2019 © The Author(s) 2019 Abstract Exposure to mite allergens, especially from storage and dust mites, has been recognized as a risk factor for sensitization and allergy symptoms that could develop into asthma. The aim of this study was to investigate the occurrence of mites in debris and litter from selected farm buildings of the Małopolskie province, South Poland, with particular refer- ence to allergenic and/or parasitic species as a potential risk factor of diseases among farm- ers. Sixty samples of various materials (organic dust, litter, debris and residues) from farm buildings (cowsheds, barns, chaff-cutter buildings, pigsties and poultry houses) were sub- jected to acarological examination. The samples were collected in Lachowice and Kurów (Suski district, Małopolskie). A total of 16,719 mites were isolated including specimens from the cohort Astigmatina (27 species) which comprised species considered as allergenic (e.g., Acarus siro complex, Tyrophagus putrescentiae, Lepidoglyphus destructor, Glycy- phagus domesticus, Chortoglyphus arcuatus and Gymnoglyphus longior). Species of the families Acaridae (A. siro, A. farris and A. immobilis), Glycyphagidae (G. domesticus, L. destructor and L. michaeli) and Chortoglyphidae (C. arcuatus) have been found as numeri- cally dominant among astigmatid mites. The majority of mites were found in cowsheds (approx. 32%) and in pigsties (25.9%). The remaining mites were found in barns (19.6%), chaff-cutter buildings (13.9%) and poultry houses (8.8%). -

Davidova, V. Vasilev, N. Ali, J. Bakalova Konstantin Preslavsky University of Shumen, 115, Universitetska Str., Shumen, 9700, Bulgaria. ABSTRACT: The aims of the present paper are to establish the specific structure of communities of prostigmatic and mesostigmatic mites in nests of the semi-collared flycatcher (Ficedula semitorquata) and to compare the fauna with the mites in nests of two other European flycatchers. For analysis of community structure of mites were used the indices: prevalence, relative density, mean intensity and dominance. Mite communities are strongly dominated by the species Dermanyssus gallinae and Ornithonyssus sylviarum, which were found with the highest frequency and dominance. The mite communities are characterized by a large number of subrecedent species. KEYWORDS: Acariformes, Parasitiformes, Nest of Bird, Community Structure INTRODUCTION The nests of different species of birds are an example of a fairly unstable and isolated habitat, with its own dependent on it specific fauna which involves different groups of invertebrate animals. One of the components of this fauna which demonstrates particular abundance is the arthropods, and more specifically, the mites. The studies of Parasitiformes show that mesostigmatic mites living in birds' nests vary both in terms of their species affiliation and the structure of their communities [4, 8]. Highly important with respect to veterinary science and medicine are a number of species, such as Ornithonyssus bursa, Ornithonyssus sylviarum, Dermanyssus gallinae harboured by birds, Ornithonyssus bacoti, harboured by rodents, etc. -

Where Dust Mites Live Because house dust mites feed on shed human skin scales, mattresses and pillows are ideal places for mite infestations and have the highest levels of mite allergens. House dust mites thrive in warm, humid environments. They prefer temperatures at or above 70 degrees. Wall-to-wall carpeting, central heating, bedding, upholstered furniture, wallpaper or even stuffed toys provide ideal conditions for dust mites. Although mattresses and bed covers at home are the major source of mite allergens, mite-allergic patients are also exposed to signifi cant mite allergens in public places such as schools, movie theaters and public transportation. >> Treatment Learn More about IT While avoidance measures should always be the Consult an Allergy Specialist.

House Dust Mite
House dust mite House dust mite (D. Farinae) is a microscopic creature not visible to the naked eye. Mites thrive and multiply in warm, humid conditions of the home. These bugs do not bite or transmit disease; they feed off scales and dander shed by humans. They cause allergy in a sensitive person when their scales, fecal particles (each mite makes about 20 per day), and even the disintegrating body parts of dead mites become airborne and inhaled. When a sleeping person moves on the mattress, the mattress give out a cloud of these fine particles (about 10 u in size). The mite's life cycle from egg to adult is about 30 days, and each egg-laying female can increase the population by 25 to 30 every 3 weeks. In the U.S., live mite numbers peak in July and August, and allergens persist at high numbers through December. Because the airborne particles cause allergy, the worst symptoms are experienced in the fall months when the home is closed and ventilation is restricted. It is also possible that mites die in the fall in large numbers, disintegrate, and their body parts give a saturated exposure to the allergic patient. Mite are inactive and least populous in April and May. Mites are found all over the world. The European mite is somewhat different but behaves the same way. Recommended Control Measures Since mites feed on organic matter, anything made of animal skin should be removed from the bedroom (feather pillow, feather bed, wool blankets, down pillows and comforters, silk filled bedding, sheep skins, etc.) Pillows, mattress, and box springs should be encased in plastic or in a vinyl barrier bag (check local Sears or JC Penny), and the zipper sealed with a tape.
