Bdellidae (Trombidiformes: Prostigmata) are moderate to large sized predatory mites that inhabit soil, leaves, leaf litter, and intertidal rocks. They readily recognized by an elongated, snout-like gnathosoma elbowed pedipalps bearing two (one in Monotrichobdella Baker & Balock) long terminal setae. Despite being among the first ever described, with species described Carl Linnaeus, knowledge about bdellids has never been compiled into a taxonomic catalogue. Here we present catalogue...

Deer keds (Diptera: Hippoboscidae: Lipoptena Nitzsch, 1818 and Neolipoptena Bequaert, 1942) are parasitic flies that primarily attack cervids occasionally bite humans. Recent reports have documented nearly half a dozen pathogens in deer keds, but it is unknown whether competent vectors. Although geographic ranges of the four North American ked species known generally, precise limits not well understood. If vectors, knowing where they occur will inform risk pathogen transmission to people...

Two hundred and sixty-two adventive aphids (Hemiptera: Aphidoidea) have been previously reported in North America north of Mexico. We update this to include 25 unrecorded species, information on the location date first discovery, biogeographic origin, economically important American hosts for these species. The number species introduced per year has decreased overall since 1930.We discuss intercepted at United States ports entry identified by Systematic Entomology Laboratory from 2000–2016...

Xyris spp., commonly known as yellow-eyed grasses, do not possess nectaries and were thought to attract many insect visitors. The majority of visitation studies carried out on this genus have been limited North American species, despite its center diversity being in South America. discovery a potential new fungal mimicry system spp. the for pattern alteration by fungus led us assess arthropod three regions Guyana. Arthropods photographed identified morphologically. Here, we provide first...

Trachymolgus purpureus Fisher & Dowling sp. n. is described from the Ozark highlands of North America. A diversity imaging techniques are used to illustrate species including low-temperature scanning electron microscopy (LT-SEM), stereomicrography, compound light micrography, and digitally created line drawings. Developmental stages (larva, nymphs, adult) morphology illustrated discussed, terminological corrections suggested. recki Gomelauri, 1961 regarded as being tritonymphs. key presented.

Water mites (Acariformes: Hydrachnidia) are one of the planet's most diverse and abundant groups aquatic arthropods. With more than 7,500 described species, water have been documented in nearly every known freshwater environment. In lotic systems, commonly found fast-flowing, riffle-run stream habitats, where square meter substrate can contain as many 5,000 individual representing 50 30 genera, all 8 superfamilies. Despite their widespread distribution, relative diversity, abundance, widely...

Introduction There is overwhelming evidence of declines in native bee populations and therefore a need for increased monitoring to track these assist conservation restoration efforts. Bees can be sampled non-lethally through visual surveys (e.g., distance transects) or lethally active hand netting) passive traps that lure insects from afar) methods. These lethal methods suffer imperfect detection difficult account confound inferences about habitat characteristics. Additionally, suggests...

Abstract European deer keds, Lipoptena cervi (Linnaeus, 1758), are hematophagous ectoparasitic flies known to bite cervids and noncervids, including humans. To prevent keds from landing biting hosts, 5 commercially available insect repellents (DEET, IR3535, oil of lemon eucalyptus (OLE), picaridin, permethrin) water control were evaluated determine repellency efficacy postexposure mortality keds. While there was a significant difference between the groups tested, post hoc analysis revealed...

We provide collection records of beetle species belonging to eight families collected at the site. Thirty one represent new state records: (Buprestidae) Actenodes acornis, Agrilus cephalicus, ohioensis, paracelti, Taphrocerus nicolayi; (Carabidae) Agonum punctiforme, Synuchus impunctatus; (Curculionidae) Acalles clavatus, minutissimus, Acoptus suturalis, Anthonomus juniperinus, Anametis granulata, Idiostethus subcalvus, Eudociminus mannerheimii, Madarellus undulatus, Magdalis armicollis,...

White-tailed deer (Odocoileus virginianus) host numerous ectoparasitic species in the eastern USA, most notably various of ticks and two keds. Several pathogens transmitted by to humans other animal hosts have also been found Little is known about acquisition potential for transmission these keds; however, tick-deer ked co-feeding one possible scenario. On-host localization keds on white-tailed was evaluated across several geographical regions US define spatial relationships deer, which may...

Abstract Emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is an invasive beetle attacking North American trees (Fraxinus L. [Oleaceae]). Populations in infested areas are monitored with purple sticky traps. During summer 2008, we nine pairs of traps and clear control to determine which other insect families attracted these whether might be used monitor pest insects. We argue that monitoring bycatch could greatly increase the potential finding species.

Abstract Deer keds (Diptera: Hippoboscidae: Lipoptena Nitzsch, 1818 and Neolipoptena Bequaert, 1942) are blood-feeding ectoparasites that primarily attack cervids occasionally bite humans, while ticks may be found on cervids, but more generalized in host choice. Recent detection of pathogens such as Anaplasma Borrelia deer historical infections tick-borne diseases provides reason to investigate these vectors. However, previous methods employed sample vary, making it difficult standardize...

The descriptive biology of torrent mites (Parasitengona: Torrenticolidae: Torrenticola) North America (north Mexico) is investigated using integrative methods.
