AbstractMany aquatic insect species, including aquatic Hemiptera, are parasitized by water mite larvae. Although this situation may cause damaging impacts to the hosts, the mites can disperse and colonize new localities in this way. Little is known about the frequency of water mite ectoparasitism amongst the aquatic Hemiptera in Turkey. In this study, larval water mite parasitism on aquatic Hemiptera, which have been collected from different localities in Turkish Thrace, was evaluated. It was found that only nine individuals, belonging two different species in a total of 367 hemipteran specimens, were parasitized by larval water mites. Furthermore, variations in sizes and shapes of the mites on the waterscorpion Ranatra linearis Linne, 1758 and Nepa cinerea Linne, 1758 were determined. These are the first records for larval mite parasitism on R. linearis and N. cinerea in Turkish Thrace.

AbstractLarvae of a vast majority of water mite species are parasites of aquatic insects. Owing to this, they migrate to new localities, and are able to survive unfavourable environmental conditions. This also concerns species from subgenus Arrenurus s. str., parasites of dragonflies. The detailed analysis of this phenomenon, however, has only been possible in the last several years, since the key to the identification of larvae from genus Arrenurus Dug. was published. In 2010, the parasitism of Arrenurus s. str. larvae on dragonflies in the Lake Świdwie reserve (NW Poland) was analysed. Larvae of 9 species of water mites were recorded on 107 imagines of dragonflies from 8 species. The following were identified as hosts of water mites for the first time: Anax imperator, Libellula quadrimaculata, and Leucorrhinia caudalis. The highest prevalence occurred in the case of: Erythromma najas and Lestes dryas (100%), Coenagrion pulchellum (96.5%), and C. puella (80.0%). Coenagrion pulchellum was infested by 9 species of parasites, C. puella by 6, and Erythromma najas and Lestes dryas by three species. The highest number of host species occurred in the case of Arrenurus maculator (5); followed by A. cuspidator, A. batillifer cf., A. bicuspidator, and A. tetracyphus (3 each); A. papillator, A. tricuspidator, and A. bruzelii (2 each), and A. claviger (1). Differentiation of preferences of particular parasites towards various parts of the host body was observed, probably related to the coevolution of parasites and hosts, and competition between the host species. The body sizes of the parasites suggest that approximately 50% of body size growth of water mites from subgenus Arrenurus s. str. occurs at the stage of parasitic larva.

Preliminary Results

An intensive field survey on aquatic insects of Me Linh Station for Biodiversity in Vinhphuc province was conducted in December 2015. Specimens were collected at 8 different sites and aquatic insects were collected both quantitatively by Surber net and qualitatively by hand net, pond net. As a result, a total of 110 aquatic insect species belonging to 98 genera, 49 families and 9 orders were recognized. Among these, the order Ephemeroptera had the highest species number with 26 species, followed by Odonata with 25 species, Trichoptera with 18 species, Coleoptera with 15 species, Hemiptera with 11 species, Diptera with 9 species. Lepidoptera, Plecoptera and Megaloptera had the lowest of species number, represented by 3 species of Lepidoptera, 2 species of Plecoptera and 1 species of Megaloptera. Besides, the quantitative analysis results and the functional feeding groups were provided.

Anatomy and ultrastructural organization of the larval mouthparts in representatives of terrestrial (Trombiculidae parasitizing vertebrates and Microtrombidiidae parasitizing arthropods) as well as aquatic (Pionidae and Hydrodromidae parasitizing arthropods) families from the cohort Parasitengona were studied using whole-mount preparations, semi-thin sections and TEM and SEM methods. In these groups, the organization of the mouth apparatus differs significantly especially with regard to their particular functional specialization and adaptations reflecting evolutionary trends in these groups. In trombiculid larvae, the mouthparts reveal the simplest organization. The gnathosoma is totally free, the infracapitulum and the basal cheliceral segments are short and wide, and the latter are separated from each other. The flexible lateral lips form a temporary sucker, distinguishable when the larva feeds, and the pharynx is totally fused with the bottom of the infracapitulum. In microtrombidiid larvae, the gnathosoma is covered by the arched dorsal shield, the chelicerae are comparatively long and separated, and the lateral lips form a permanent sucker provided with an internal sclerite. Conversely, in water mite larvae, the chelicerae are fused together and either partially (Piona carnea) or totally (Hydrodroma despiciens) free from the overhanging idiosomal fold. The lateral lips are flexible and organized freely, and the pharynx is totally separated from the bottom of the infracapitulum. In general, water mite larvae show significant variations and specializations but at the same time seem to possess the most plesiomorphic characters in organization of the mouth apparatus. The ancestral parasitengone may have given rise to divergent groups of water mites as such, as well as to trombiculids with the secondary simplification of the mouth apparatus and to microtrombidiids with their particular additional adaptations and specialization in organization of the mouthparts.

Water mites are a large group of macroinvertebrates that are very vulnerable to contamination and environmental changes. As a result, they are often used to monitor water quality. Khankra gad stream, a third-order perennial spring-fed stream of the Alaknanda River in Uttarakhand, India, was studied to determine the drift behavior of water mites and water quality. Drift nets were set up for 24 hours in both spots of the Khankra stream where there was little or no human influence over a two-year sampling period (June 2018-20). Every four hours, the nets were changed out with new ones. Water mites signify a particular drift month and diel drift pattern. The majority of the drift mite species were present in considerably higher numbers in the daytime. During the two-year study period, a total of 2503 mite samples were collected from the Khankra stream, from which 204 water mite species drifted. The least number of Hydrachnidia (694) were collected from Spot-1, and the highest (1809) were collected from Spot-2, with 106 water mites drifting from Spot-1 and 134 mites drifting from Spot-2 during the study period. From Spot-2 maximum 25 mite species were collected and minimum 19 mite species were collected from Spot-1. For various mite species, the DBDI value ranged from 0.155 (July) to 0.204 (April) in Spot-1 and 0.134 (July) to 0.149 (February) in Spot-2. It was also observed that maximum water mite species were day-drifter. The physico-chemical parameters of the Khankra stream were also reported. The effect of ecological parameters on mite drift was investigated using Canonical correspondence analysis (CCA).
