An overview of agricultural neonicotinoid regulation in the EU, Canada, and the United States

Pest Management Science, EarlyView.
Grounded in broad environmental coalition and place‐based research, the European Union, Ontario and Québec in Canada, and several US states placed restrictions on agriculturally‐applied neonicotinoids. The exact regulations and how they were implemented are explored.

A comparative analysis of heartworm medication use patterns for dogs that also receive ectoparasiticides

Parasites & Vectors, 2018
Background Heartworm medications and many oral or topical flea and tick products are provided as monthly doses while a newer oral flea/tick product, fluralaner (BRAVECTO® Chew), is re-dosed at a 12-week interval. This study focused on whether there was a

RNA degradomics and proteomics reveal the mechanism of dsProsβ1‐mediated proteasome targeting in Psylliodes chrysocephala

Pest Management Science, EarlyView.
RNA degradomics revealed dsProsβ1‐derived siRNA‐mediated mRNA cleavage events, mainly at uracil‐guanine and adenine‐adenine pairs. Proteasome inhibition via dsProsβ1 increased mitochondrial and cytoskeletal proteins while reducing translation‐related and mRNA‐binding proteins.

Relationships between functional alpha and beta diversities of flea parasites and their small mammalian hosts

Parasitology
We studied the relationships between functional alpha and beta diversities of fleas and their small mammalian hosts in 4 biogeographic realms (the Afrotropics, the Nearctic, the Neotropics and the Palearctic), considering 3 components of alpha diversity (

Biodiversity of Potential Vectors of Rickettsiae and Epidemiological Mosaic of Spotted Fever in the State of Paraná, Brazil

Frontiers in Public Health, 2021
Spotted Fever Rickettsioses (SFR) are diseases caused by bacteria of the genus Rickettsia, and are transmitted mainly by ticks. Its eco-epidemiological scenarios vary spatially, and may also vary over time due to environmental changes.

Insecticide Resistance in Fleas [PDF]

Insects, 2016
Fleas are the major ectoparasite of cats, dogs, and rodents worldwide and potential vectors of animal diseases. In the past two decades the majority of new control treatments have been either topically applied or orally administered to the host. Most reports concerning the development of insecticide resistance deal with the cat flea, Ctenocephalides ...

Biomechanics of jumping in the flea [PDF]

Journal of Experimental Biology, 2011
SUMMARY It has long been established that fleas jump by storing and releasing energy in a cuticular spring, but it is not known how forces from that spring are transmitted to the ground. One hypothesis is that the recoil of the spring pushes the trochanter onto the ground, thereby generating the jump.

Bed bug preferences for host odor or aggregation odor are differentially modulated by physiological state in various odorscapes

Pest Management Science, EarlyView.
The bed bug olfactory system is highly tuned to two odor sources with dedicated odor information‐processing pathways that are modulated by the satiety–hunger state. Understanding the dynamic nature of switching odor preferences at different phases of blood digestion will contribute to the development of lures with host kairomones and aggregation ...

Evaluation of the murine immune response to Xenopsylla cheopis flea saliva and its effect on transmission of Yersinia pestis.

PLoS Neglected Tropical Diseases, 2014
Background/aimsArthropod-borne pathogens are transmitted into a unique intradermal microenvironment that includes the saliva of their vectors. Immunomodulatory factors in the saliva can enhance infectivity; however, in some cases the immune response that

Flea sharing among sympatric rodent hosts: implications for potential plague effects on a threatened sciurid

Ecosphere, 2020
For vector‐borne diseases, the abundance and competency of different vector species and their host preferences will impact the transfer of pathogens among hosts.
