Parasites have been investigated for some New World primates; however, very little is known about ectoparasites and specifically fur mites. In this study, Alouatta palliata, Cebus capucinus, Saimiri oerstedii, and Ateles geoffroyi monkeys from different areas of Costa Rica were searched for fur mites. A total of 276 monkeys were evaluated, and 51 of them were positive for mites of the family At...

Sheep scab mites, Psoroptes ovis, collected from a Merino donor sheep, were used to infest Merino and Dorper sheep, and Angora and Boer goats. Mites were placed on the sheep on 1 or 2 occasions and on 5 occasions on the goats. All the animals were examined at regular intervals for the presence of scab lesions and living mites. Both sheep breeds developed lesions, but those on the Merino sheep w...

In the black-spruce clay-belt region of Western Québec, soil nutrients are limited due to paludification. Under paludified conditions, nutrient subsidies from decomposing surface coarse woody material (CWM) may be important particularly during the later stages of ecosystem development when deadwood from senescent trees has accumulated. For soil organisms, CWM can alter microclimatic conditions ...

Arthropods at different stages of development collected from human remains in an advanced stage of decomposition (following autopsy) and from the soil at the scene are reported. The corpse was found in a mixed deciduous forest of Biscay (northern Spain). Soil fauna was extracted by sieving the soil where the corpse lay and placing the remains in Berlese-Tullgren funnels. Necrophagous fauna on t...

Population abundances of both Acarina (mites) and Collembola (springtails) were examined for continuous corn grown under no-till and conventional management practices on a clay loam, an Orthic Humic Gleysol (Typic Haplaquoll) near Ottawa, Ont., Canada (Lat. 458 220 N; Long. 758 430 W). For each tillage practice, samples for soil faunal extraction and soil attribute characterization were taken p...

Climatic and biome changes of the past million years influenced the population structure and genetic diversity of soil-living arthropods in Europe. However, their effects on the genetic structure of widespread and abundant soil animal species such as the Collembola Parisotoma notabilis remain virtually unknown. This generalist and parthenogenetic species is an early colonizer of disturbed habit...

The Ophiostomatales is an Ascomycete order of fungi that accommodates several tree pathogens and many species that degrade wood. These fungi are commonly vectored by Scolytine bark and ambrosia beetles. In recent years it has also been shown that hyperphoretic mites on these beetles can vector some Ophiostomatales. Little is known regarding the Ophiostomatales in China and we have consequently ...

On a worldwide basis, mites are important nuisance pests and some are capable of transmitting disease causing agents to humans. There are many different species of bloodsucking mites, some mites live in people’s skin (mites that cause scabies), while other species may take blood meals on human hosts. For this reason, this article has been designed to highlight disease agents vectored by mites a...

A 36-yr-old male captive siamang (Symphalangus syndactylus) was evaluated for mange in the form of generalized alopecia, flaky skin, and pruritus of 1 mo duration. Multiple skin scrapings and biopsies revealed high numbers of trombidiiform mites identified as Psorobia (formerly Psorergates) sp. near cercopitheci (Acarina: Psorergatidae) based on morphologic characteristics. Prolonged repetitive...

A wide range of technology is available for application of entomopathogenic nematodes including various irrigation systems and spray equipment. The choice of application equipment, and manner in which the nematodes are applied, can have substantial impact on pest control eYcacy. For example, nozzle or pumping system types are some of the parameters that can aVect nematode performance following ...
