Abstract:

In a mutualistic relation between a potter wasp, Allodynerus delphinalis (Giraud) (Hymenoptera: Vespidae), and its specific parasitic mite, Ensliniella parasitica Vitzthum (Winterschmidtiidae), behaviour of the mite guarding the wasp and attacking their common natural enemy, Melittobia acasta (Walker) (Hymenoptera: Eulophidae), was examined.While mite attacks to M. acasta occurred by accidental physical contact, the counterattack by the parasitoid occurred 24 h after both were released onto their mutual host. The two organisms fought until one of them died in our experimental arena, which the

A field study was conducted to determine if nest modifications could reduce mite parasites and parasitoid natural enemies that attack managed O. cornifrons.

Abstract:

AbstractMany natural enemies of herbivorous arthropods can use herbivore-induced plant volatiles to locate their prey. The composition of herbivore-induced volatile blends is highly variable, e.g., for different plant or herbivore species. When this variation is predictable during the lifetime of an individual, learning is expected to be adaptive for natural enemies that use such information. Learning has indeed been demonstrated many times for parasitoid wasps that use herbivore-induced plant volatiles to locate their hosts. However, evidence for learning of plant volatiles by predatory mites

Through these two major biotic interactions, water mites have been found to greatly impact a variety of mosquito species.

The biogeography of organisms, particularly those with complex lifestyles that can affect dispersal ability, has been a focus of study for many decades.

However, does this actually occur?

Abstract:

Here we identify, for the first time, a generalist orange parasitic mite found on multiple small-mammal species in Algonquin Provincial Park, Ontario, Canada. Results from 18S rRNA sequencing suggest that these mites may belong to the family Trombiculidae (Acari: Trombidiformes), although morphological and additional genetic analyses are needed to confirm this identification. The presence of these mites was associated with lower body condition in North American red squirrels (Tamiasciurus hudsonicus (Erxleben, 1777)), suggesting that these mites may be a detriment to fitness in small mammals o

Abstract:

Feather mites (Acari: Astigmata) have been reported to be parasitic, commensal, and even mutualistic on the birds that serve as their hosts. We investigated whether there was a relationship between number of feather mites ( Pteronyssoides obscurus (Berlese, 1885)) on the wing and daily survival of cliff swallows ( Petrochelidon pyrrhonota (Vieillot, 1817)) during the breeding season at 12 nesting colonies in Nebraska in 2005. Survival of birds with known mite loads was monitored by mark–recapture, and survival models with and without a linear effect of mites were compared with the program MARK

Abstract:

The diversity of avian nasal mites has been incompletely studied in South America and most reports have been made on the fauna of Brazil, especially from the 1940s to 1970s. Recently, the development of new research has contributed records of species not previously reported in the country. As a result, a compilation of records of nasal mites (Astigmata: Cytoditidae, Turbinoptidae; Prostigmata: Ereynetidae; Mesostigmata: Rhinonyssidae) of birds in Brazil is presented. One hundred and twenty-four species of nasal mites were recorded parasitizing 168 bird species. The Rhinonyssidae was the family

ABSTRACT The worldwide decline in honeybee colonies during the past 50 years has often been linked to the spread of the parasitic mite Varroa destructor and its interaction with certain honeybee viruses. Recently in the United States, dramatic honeybee losses (colony collapse disorder) have been reported; however, there remains no clear explanation for these colony losses, with parasitic mites, viruses, bacteria, and fungal diseases all being proposed as possible candidates. Common characteristics that most failing colonies share is a lack of overt disease symptoms and the disappearance of wor

The ectoparasitic mite Varroa destructor poses one of the biggest threats to the western honeybee Apis mellifera.

The goal of our work was to evaluate the effects of the entomopathogenic fungus Metarhizium anisopliae var. anisopliae BIPESCO 5, which is a potential biological control agent against the bee parasitic mite V. destructor, on the behavior of the parasite.

The relationships between feather mites and their avian hosts have great potential as subjects for studies of evolution and ecology.

SUMMARYTemperature can be a limiting factor on parasite development. Riccardoella limacum, a haematophagous mite, lives in the mantle cavity of helicid land snails. The prevalence of infection by R. limacum in populations of the land snail Arianta arbustorum is highly variable (0–78%) in Switzerland. However, parasitic mites do not occur in host populations at altitudes of 1290 m or higher. It has been hypothesized that the host's hibernation period might be too long at high elevations for mites and their eggs to survive. To test this hypothesis, we experimentally infected snails and allowed t

The distribution of Varroa jacobsoni on clustered, overwintering workers of Apis mellifera was investigated. The majority of mites were found between the 3rd and 4th ventro-lateral tergites of the abdomen with a significant preference for the left side of the host. This position would enable the mites to place their mouthparts in close proximity to the central portion of the bees' ventriculus. This may allow the mites access to nutrients at higher concentrations than would occur elsewhere in the haemolymph.
