Vet Parasitol 2019 4;276S:100009. Epub 2019 Apr 4.

Department of Diagnostic Medicine/Pathobiology, Kansas State University, Manhattan, KS 66506, USA. Electronic address:

Post-launch field investigations of recently-approved flea control products establish an efficacy baseline and in subsequent years can detect any efficacy decline suggestive of emerging resistance. As part of a continuing program of yearly assessment of flea control products in west central Florida, this study, using client-owned dogs, investigated the efficacy of lotilaner and spinosad in controlling fleas and in alleviating dermatologic signs likely associated with flea infestations. Forty-four qualifying households were randomized to either a lotilaner (Credelio®) (minimum dose rate 20 mg/kg) or a spinosad (Comfortis®) (30 mg/kg) group, with 33 and 36 dogs in each group, respectively.

Interrelationship of soil moisture and temperature to sylvatic plague cycle among prairie dogs in the Western United States.

Integr Zool 2021 Jul 4. Epub 2021 Jul 4.

Department of Veterinary Pathobiology, University of Missouri, Columbia, USA.

Plague, caused by Yersinia pestis (Lehmann & Neumann, 1896), is a flea-borne disease that is endemic in areas throughout the world due to its successful maintenance in a sylvatic cycle, mainly in areas with temperate climates. Burrowing rodents are thought to play a key role in the enzootic maintenance as well as epizootic outbreaks of plague. In the United States, prairie dogs (Cynomys, Rafinesque, 1817), rodents (Muridae, Illiger, 1811), and ground squirrels (Spermophilus, F. Read More

Poor vector competence of the human flea, Pulex irritans, to transmit Yersinia pestis.

Parasit Vectors 2021 Jun 10;14(1):317. Epub 2021 Jun 10.

Laboratory of Bacteriology, Rocky Mountain Laboratories, National Institute of Allergy and Infectious Diseases, NIH, Hamilton, MT, USA.

Background: The human flea, Pulex irritans, is widespread globally and has a long association with humans, one of its principal hosts. Its role in plague transmission is still under discussion, although its high prevalence in plague-endemic regions and the presence of infected fleas of this species during plague outbreaks has led to proposals that it has been a significant vector in human-to-human transmission in some historical and present-day epidemiologic situations. However, based on a limited number of studies, P. Read More

Hijacking the Mustard-Oil Bomb: How a Glucosinolate-Sequestering Flea Beetle Copes With Plant Myrosinases.

Front Plant Sci 2021 20;12:645030. Epub 2021 May 20.

Research Group Sequestration and Detoxification in Insects, Max Planck Institute for Chemical Ecology, Jena, Germany.

Myrosinase enzymes play a key role in the chemical defense of plants of the order Brassicales. Upon herbivory, myrosinases hydrolyze the β-S-linked glucose moiety of glucosinolates, the characteristic secondary metabolites of brassicaceous plants, which leads to the formation of different toxic hydrolysis products. The specialist flea beetle, , is capable of accumulating high levels of glucosinolates in the body and can thus at least partially avoid plant myrosinase activity. Read More

Adaptation to a novel host and performance trade-off in host-generalist and host-specific insect ectoparasites.

Insect Sci 2021 May 28. Epub 2021 May 28.

Mitrani Department of Desert Ecology, Swiss Institute for Dryland Environmental and Energy Research, Jacob Blaustein Institutes for Desert Research, Ben-Gurion University of the Negev, Sede Boqer Campus, Midreshet Ben-Gurion, Israel.

We investigated the performance trade-offs of fleas (Siphonaptera) while adapting to a novel host using two host generalists (Xenopsylla conformis and Xenopsylla ramesis) and one host specialist (Parapulex chephrenis) maintained on their principal hosts (Meriones crassus for Xenopsylla and Acomys cahirinus for P. chephrenis). We asked whether, over generations, (i) a host generalist may become a specialist by evolving the ability to exploit a novel host and losing the ability to exploit an original host and (ii) a host specialist can become a generalist by evolving the ability to exploit a novel host without losing the ability to exploit an original host.
