Explorational analysis of the abundance and prevalence of chigger and gamasid mites parasitic on small mammals in Vietnam.

We studied chigger and gamasid mite loads on small mammals during the dry season in Vietnam and used both our field data and museum collections to estimate the influence of environmental factors on mite abundance and prevalence. Generalized linear (mixed effect) models were used to analyze the data. We examined 1,239 small mammal individuals, which were obtained from field expeditions and museum collections belonging to 59 species.

New species and new records of chigger mites (Acariformes, Trombiculidae) from Cambodia.

Two new chigger species, Leptotrombidium mondulkiri sp. nov. and Walchia keoseima sp.

New data on the distribution of chigger mites (Acariformes: Trombiculidae) associated with small mammals in Vietnam.

The study of chigger mites of Vietnam is based on the material collected during fieldworks in 20112019 and examination of small mammal samples deposited in museum collections. A total 59 small mammals species were examined (49 species of Rodentia, 8 species of Eulipotyphla, and 2 species of Scandentia). On them, 79 species of chigger mites were collected, of which 44 species are recorded in Vietnam for the first time.

Bat ectoparasites: chigger mites (Trombiculidae), ticks (Ixodidae and Argasidae), and bugs (Cimicidae) in the Eastern Palaearctic.

Nine species-level taxa of bat ectoparasites, three chigger mites (Trombiculidae), three hard (Ixodidae), and one soft tick (Argasidae) species, as well as two bug (Cimicidae) species from nine bat species hosts were detected in the Eastern Palaearctic. Trombiculid larvae of Leptotrombidium schlugerae, Leptotrombidium album, and Ascoschoengastia latyshevi were first recorded on bats in the temperate zone of eastern Russia. L.

Re-descriptions of eight chigger mite species (Acariformes: Trombiculidae) of the Leptotrombidium generic complex from Vietnam.

Six mite species of the genus Leptotrombidium Nagayo, Miyagawa, Mitamura and Imamura, 1916 and one species from each of the genera Lorillatum Nadchatram, 1963 and Trombiculindus Radford, 1948, incompletely described by Schluger et al. (1960b, 1963) from rodents and tree shrews in North Vietnam, are re-described based on type series. Lectotypes and paralectotypes have been designated for all redescribed species.
