Insect chemosensory proteins as targets in insecticide resistance and development

New Plant Protection, EarlyView.
This review addresses the biological and chemical properties of insect chemosensory proteins (CSPs) and presents their functional advancements, not only in olfaction but also in nonolfactory processes, particularly in relation to insecticide resistance.

Controlling Ectoparasites on Welsh Organic Sheep Farms [PDF]

, 2003
1. Organophosphate (OP) based dips offer a broad spectrum control against all major ectoparasites in the UK. However, there is continuing controversy over the safety to dip operators and the environment. The use of OPs is prohibited by organic standards,

Isolation and identification of ectoparasites in single humped camels (Camelus dromedarius) of Cholistan area, Pakistan

Iraqi Journal of Veterinary Sciences, 2019
Thirty herds comprising four hundred and fifty camels (Camelus dromedarius ) ranging from 5 months to 17 years of age were subjected to external examination of ectoparasites (ticks, mange mites and flies) during November 2010 to July 2011 at Cholistan ...

Three's a crowd: The relationship among endoparasites, an epibiont and their Daphnia host

Oikos, EarlyView.
In freshwater communities, organisms interact in a variety of ways, including predation, competition and parasitism. Parasites are ubiquitous, playing an important role in shaping freshwater communities. Endoparasites live within internal organs of their host, while ectoparasites, also known as epibionts, are confined to the external part of the host's

Prevalence and diversity of Rickettsia species in ectoparasites collected from small rodents in Lithuania

Parasites & Vectors, 2018
Rickettsiae are emerging pathogens causing public health problems in many countries around the world. Rickettsia spp. are found in association with a wide range of arthropods which feed on different species of animals.

Variation in prevalence and intensity of macroparasites in moose and their interactions with winter tick load in eastern Canada

Wildlife Biology, EarlyView.
Wild animals are infected with a large diversity and abundance of parasites that can affect their behavior, growth, body condition, and ultimately their survival. Although the adverse effects of parasites and the mechanisms involved in the interactions between a host and its parasites are generally well studied, much less is known about the additive or

Lichens in the nests of European starling Sturnus vulgaris serve a mate attraction rather than insecticidal function [PDF]

, 2018
The European starling Sturnus vulgaris is a hole-nesting bird in which the male builds a voluminous nest using a wide variety of materials such as twigs, grass, leaves, feathers, and lichens.

Function of Combs in Ectoparasites [PDF]

Nature, 1967
MANY ectoparasitic insects are characterized by one or more regular rows of closely set, large stout spines. These rows of spines are termed combs, or ctenidia, and have evolved independently in fleas (Siphonaptera), bat flies (Nycteribiidae), bat bugs (Polyctenidae), and in the beaver beetle Platypsyllus.

Factors associated with diversity, quantity and zoonotic potential of ectoparasites on urban mice and voles

PLoS ONE, 2018
Wild rodents are important hosts for tick larvae but co-infestations with other mites and insects are largely neglected. Small rodents were trapped at four study sites in Berlin, Germany, to quantify their ectoparasite diversity.
