“…Specimens (adults and tritonymphs) of the laboratory culture Archegozetes longisetosus ran (founded by Roy A. Norton ;Heethoff et al, 2007;Heethoff et al, 2013) were used as prey, because their defensive gland chemistry is well known (Sakata and Norton, 2003;Raspotnig and Föttinger, 2008;Heethoff and Raspotnig, 2011). Furthermore, the species has been used in feeding experiments before (Heethoff et al, 2011;Heethoff and Raspotnig, 2012a) and a functional response model of reservoir based chemical defense in predator-prey interactions has been described (Heethoff, 2012;Heethoff and Rall, 2015).…”

“…Setae are mechano-or chemoreceptors (Baker, 1996) and are of importance for inter-and intraspecific communication (Heethoff et al, 2013). During the development, the number of setae increases (Seniczak and Seniczak, 2009).…”

“…Here, we studied the gross morphology and development of the synganglion in Archegozetes longisetosus ran (Actinotrichida, Oribatida; Heethoff et al, 2007), a parthenogenetic species previously used to investigate chelicerate development (Telford and Thomas, 1998a; Thomas and Telford, 1999;Barnett and Thomas, 2012;Bergmann and Heethoff, 2012;Heethoff et al, 2013). Adult stages reach from 800 mm to 1100 mm in body size (Seniczak, 1998).…”

Small arthropods show a highly condensed central nervous system, which is accompanied by the loss of the ancestral metameric organization. This results in the formation of one solid mass, a synganglion. Although numerous studies investigated the morphology of Archegozetes longisetosus, the organization of the nervous system is to date unknown. Using synchrotron X-ray microtomography, we investigated the organization of the nervous system in the adult stage and the development of the synganglion over all five free-living life stages (larva, proto-, deuto-, tritonymph and adult). The general morphology of the synganglion resembles that of other studied mites (in the classic sense) and ticks, being subdivided into a sub- and supraesophageal region, and consisting of cortex and neuropil. All nerves entering the walking legs except the first consist of two rami. This split is not based on a functional division into a motor and a sensory ramus, but both rami contain motor and sensory neurites. Within the synganglion, we found structures that resemble the ancestral metameric organization of the nervous system of arthropods. The development of the synganglion of A. longisetosus shows a more or less linear increase in volume, but cortex and neuropil grow at different rates over the five life stages. Between the second and third nymphal stage, the volume of the neuropil increases at a faster rate than the cortex.

“…Green algae were used successfully as food for A. longisetosus in many other experiments (Honciuc 1996;Seniczak 1998;Seniczak & Seniczak 2002;alberti et al 2003, 2011Smrž & NortoN 2004;HeetHoff et al 2007HeetHoff et al , 2013remén et al 2010). The positive effect of green algae on this mite was explained by the presence of easily assimilable polysaccharides or other growth factors that are stored in algal cells (Honciuc 1996).…”

“…Archegozetes longisetosus Aoki, 1965 is a mite relatively easy to rear in laboratory conditions and therefore it has been used as a chelicerate model organism in several laboratories worldwide (HeetHoff et al 2013). It is a panphytophagous species, as demonstrated by the gut content analyses of individuals collected from the field (Haq 1982;Xavier & Haq 2007).…”

Effects of green algae and napa cabbage on life-history parameters and gut microflora ofArchegozetes longisetosus(Acari: Oribatida) under laboratory conditions

Abstract:We compared the effect of green algae (dominated by Protococcus sp.) and the earlier studied napa cabbage on the life-history parameters and gut microflora of the oribatid mite Archegozetes longisetosus (a chelicerate model organism). Napa cabbage contained more crude ash, protein, and crude fibre than green algae, but A. longisetosus developed better on the latter food, displaying higher fertility, lower mortality of offspring and shorter development than on napa cabbage. The gut microflora of A. longisetosus depended on the kind of food and developmental stage of this mite. The adults fed with napa cabbage had more abundant and more active microflora than those fed with green algae, whereas in the tritonymphs the microflora was more abundant when they were fed with green algae, and was more active in the group fed with napa cabbage. Irrespective of the treatment, the highest percentage of the isolated bacteria were gram -positive bacilli or gram-negative bacteria, but the mites feeding on Protococcus sp. contained no cocci, whereas those fed with cabbage had no gram-positive bacteria.
