Description of mouthparts in adult mites of Platytrombidium fasciatum (C.L. Koch, 1836) (Acariformes: Microtrombidiidae) with a comparison of those of the larvae
Shatrov A.B.
The mouthparts of adult mites of Platytrombidium fasciatum (C.L. Koch, 1836) (Acariformes: Microtrombidiidae) were examined using both light optical (mounted mites, toluidine blue stained semi-thin sections) and electron microscope (TEM, SEM) methods. The gnathosoma is formed ventrally by the wide gnathocoxal plate, extending forward as the cone-shaped hypostome without a conspicuous sucker, and dorsally by two-segmented chelicerae, each with a blade-like cheliceral claw (movable digit). The proximal portion of the gnathosoma is inserted into a camerostomal fold formed of the body wall. The voluminous subcheliceral space terminates posteriorly by the proximal chamber with characteristic sclerotization of its walls. Membranous bottom of the subcheliceral space bears the labrum anteriorly and the weakly expressed epistome posteriorly. The proximal chamber serves as a saliva reservoir. The labrum and the inner walls of the hypostome form the mouth leading to a crescent pharynx. The latter possesses dorsal dilators originating on the floor of the subcheliceral space and mostly on the lateral walls of the gnathocoxal plate and constrictors. The ventral pharyngeal wall is conspicuously separated from the gnathosomal bottom and has no ventral dilators. The main tracheal trunks are S-shaped in longitudinal sections and are connected with the proximal chamber through narrow channels. Posterior portions of the tracheal trunks have sclerotized walls and serve for origination of the extrinsic cheliceral muscles. The cheliceral apodemes are therefore expressed twice as the sclerotized elements behind the inner walls of the basal cheliceral segments and as the particular sclerotization of the tracheal trunks. Laterally, the gnathosoma bears large 5-segmented palps. On the dorsal aspect of the tibia, there are two sclerotized claws. Such an organization of the mouthparts of adult microtrombidiid mites seems to be closely responded to the actinedid prototype and appears to be more generalized than the specialized mouthparts of the larvae.

To the study of biocenotic relationships between house dust mites (Acariformes: Pyroglyphidae) and mould fungi
Petrova-Nikitina A.D., Antropova A.B., Mokeeva V.L., Chekunova L.N., Bilanenko E.N., Bulgakova T.A., Zheltikova T.M.
The population dynamics of two house dust mites species, Dermatophagoides pteronyssinus and D. farinae, and the mould fungi were studied during long-term culturing of mites (30 weeks) in the simple periodic cultures (SPC) without food supply added. Beard shavings (BS), were used as the food substrate. The population dynamics of D. pteronyssinus and D. farinae in SPC were similar in general and differed by the longevity of the lag-phase, exponential growth, plateau, and decline, as well as by the maximum abundance and the relative speed of the population growth.
The species diversity and abundance of micromycetes in the primary food substrate for mites (control) were low. In the following experimental period these species were not recorded anymore. In SPC of D. pteronyssinus and D. farinae 14 species of mould fungi from 6 genera were revealed. Ten species of micromycetes from 4 genera were recorded in the culture of D. pteronyssinus, and 11 species from 5 genera were found in the culture of D. farinae. The Jaccard similarity index constituted 50%. In the cultures of both species Aspergillus penicillioides predominated with the frequency value 100% and the maximum number more than 108 CFU/g of substrate. A. repens, Wallemia sebi and Chrysosporium sp. had subdominant positions. An increase in number of mites and mould in cultures was synchronous. However after reaching the plateau there were no decrease in number of micromycetes observed like in the populations of mites. These data should be taken into account when preparing mite allergens. The relationships between mites and mould can be regarded in this experiment as protocooperation.

Mating activity and physiological age of females in population of Ixodes ricinus (L.) (Acari: Ixodidae)
Mikulova N., Dusbabek F., Bouman E.A.P.
Four categories of physiological age were distinguished in females of Ixodes ricinus (L.) according to the morphological characteristics: newly emerged, physiologically young, mature and old ones. No newly emerged females were collected in the field by flagging. Spring and summer cohorts of young females were recorded during the season. The peak occurrence of mature females followed the peaks for young females. Old females occurred mainly during the second half of the season. The mean weight of unfed young females was higher than that of mature and old females. From 25±5 females investigated each week, the number of mated ones started at 11.1% in March and reached 92.3% in June. A considerable decrease in the number of mated females during August and September up to 40% was followed by an increase to 65%) at the end of season. Only 6 of 25 (24%) mated laboratory females fully engorged without males in contrast to 23 (92%) females engorging with males. The mean weight of fully engorged females feeding together with males was significantly higher (0.30 g) than of females feeding without males (0.24 g). Male presence during feeding of mated female increased the success of female feeding.

Peculiarities of cadmium-tolerant populations of Ixodes ticks: specificity of their microbiocenoses, immunity and vector capacity
Alekseev A.N., Dubinina H.V., Chirov P.A., Peterson A.M, Turtseva M.A.
The appearance and prevalence of exoskeleton anomalies in Ixodes ticks chosen as markers of anthropogenic press allows to reveal their distribution and the rate of occurrence in Russia and several Western European countries. Chemical analyses show the appearance of anomalies as being related to the accumulation of heavy metal ions, first of all cadmium which prevails in specimens and is known as changing tick metabolism. Cd concentrations are 1.5-2 times higher in anomalous ticks than in normal ones, cadmium supposedly suppressing tick immunity. To provide indirect evidence of this, microflora of anomalous and normal ticks has been compared, with 73 hungry tick females collected in April 2003 and 2004 in a focus of tick-borne diseases near St. Petersburg, Russia screened microbiologically. A study of "vulgar" microflora in both parts of the Ixodes persulcatus Schulze population shows the whole microbiocenosis of anomalous and normal ticks as being quite different. Microflora of Gram-negative and Gram-positive bacteria, bacilli, cocci and fungi appears to be much richer in anomalous ticks than in normal ones (47 versus 28 species). Only 14 (of 61) species representing the "vulgar" microflora are coincided in both groups of ticks. Not more than 4 species of microorganisms are present per normal tick, whereas one tick with exoskeleton anomalies can contain 5, 6 or even 7 species simultaneously. Only in anomalous ticks do the cocci of the genus Staphylococcus and the fungi of the genus Penicillum absolutely prevail. Staphylococci are known as active stimulants of lysozyme and defensin production, both the main tools of the tick immune system. Scarcity of these cocci and fungi in normal ticks and their abundance in anomalous ones, as well as the great prevalence of multi infections in anomalous ticks are accepted as markers of their immune system suppression. Revised (6,169 adult ticks screened using PCR; 1996-2000) data concerning the prevalence of tick-borne multi infections (such as mixtures of Borrelia, Ehrlichia, Anaplasma, Babesia or tick-borne encephalitis virus) confirm that exoskeleton anomalies represent external markers of cadmium accumulation, increased tick vector capacity and dangerousness. Analysis of anomalous tick microflora supports this observation as well, because only among anomalous tick numerous phyto- or zoopathogenic bacteria and, especially, fungi have been revealed, which can be very dangerous for man with an immune system suppressed by any factor or associated disease.

Astigmatid mites infesting chinese medicinal herbs.
Cui Yu-Bao, Li Chao-Pin, Wang Jian, Yang Qing-Gui, Tian Ye, Tao Li.
One thousand forty hundred and ninety samples of Chinese medicinal herbs belonging to Magnoliophyta (Angiospermae) were collected from a traditional medical storehouse in Huainan City, Anhui Province. Mites of thirty-five species, twenty genera, and seven families were found in nearly 57% of the samples. These results assert that Chinese medicinal herbs may be substantially contaminated, and much attention should be drawn to protection of the materials and prevention of acariasis.
