The females of the moths Hylesia metabus have their abdomens covered by urticating hairs looking like micro-arrows and causing a puriginous dermatitis to humans known as “papillonite” in French Guiana and also called yellowtail moth dermatitis or Caripito itch. The densities of the moths show great seasonal and annual variations depending on mechanisms mostly unknown. When H. metabus infestatio...

There are two general approaches for reducing the negative impacts of mountain pine beetle, Dendroctonus ponderosae Hopkins, on forests. Direct control involves short-term tactics designed to address current infestations by manipulating mountain pine beetle populations, and includes the use of fire, insecticides, semiochemicals, sanitation harvests, or a combination of these treatments. Indirec...

Examples of immunological reactions to arthropod parasites include responses by hosts to the following stimuli: excretory and secretory antigens produced by myiasis-producing larvae or skin-dwelling (mange) mites salivary antigens of blood-sucking arthropods. In many cases, these are hypersensitivity reactions, which often appear not to produce very deleterious effects on the parasites. However...

Multifamily housing facilities serving low-income populations have been at the forefront of bed bug outbreaks. Research conducted in the past 8 years has consistently proven that integrated pest management (IPM) is the best approach for successful suppression of bed bug infestations. Bed bug IPM in multifamily settings is especially dependent upon a collaborative community or building-wide effo...

Rationale White grubs (e.g. larvae of Japanese beetles or masked chafers) are the most destructive and economically injurious pests of turfgrasses in the Midwest and eastern United States. Developing grubs feed on turfgrass roots at the soil/thatch interface or in the first few centimeters of soil. Visual evidence of an infestation includes thinning, wilting in the presence of adequate irrigati...

Scabies is a common infectious disease and can cause severe outbreaks if not controlled quickly. Besides personal contact history, environmental factors are also important. This study analyzed the effects of environmental climate factors on the incidence of scabies in Taiwan. We conducted a 14-year nationwide population-based study: a total of 14,883 patients with scabies infestation were enrol...
