Co‐phylogeny and biogeography of the myrmecophilous beetle Paussus favieri (Carabidae, Paussinae) and its host ant Pheidole pallidula (Hymenoptera, Myrmicinae)

Insect Science, EarlyView.
Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐

Detection of bacterial pathogens in clade E head lice collected from Niger’s refugees in Algeria

Parasites & Vectors, 2018
Background Head lice, Pediculus humanus capitis, are obligate blood-sucking parasites. Phylogenetically, they occur in five divergent mitochondrial clades (A, D, B, C and E), each having a particular geographical distribution.

Evidence for an African cluster of human head and body lice with variable colors and interbreeding of lice between continents. [PDF]

PLoS ONE, 2012
BACKGROUND: Human head lice and body lice have been classified based on phenotypic characteristics, including geographical source, ecotype (preferred egg laying site hair or clothes), shape and color.

The effectiveness of hyposaline treatments against host-attached salmon lice [PDF]

, 2019
Understanding how salinity affects marine parasites is vital to understanding their ecology and treatment, particularly for host-parasite systems that traverse marine and freshwater realms such as the globally important Atlantic salmon (Salmo salar ...

Characterization of the dynamic microbiome evolution across thrips species

Insect Science, EarlyView.
Comprehensive survey of the microbiome in thrips. The dominant bacterial genera found in thrips include intracellular ones, such as Wolbachia and Spiroplasma, and extracellular ones, including Serratia, Pantoea, and Acinetobacter. We isolated and sequenced high‐quality genomes of two dominant symbionts, Pantoea dispersa and Serratia marcescens.

Microsomal triglyceride transfer protein in the ectoparasitic crustacean salmon louse (Lepeophtheirus salmonis)

Journal of Lipid Research, 2017
The salmon louse, Lepeophtheirus salmonis, is an endemic ectoparasite on salmonid fish that is challenging for the salmon farming industry and wild fish.

Reduced Infestation Levels of Lepeophtheirus salmonis in Atlantic Salmon (Salmo salar) following Immersion Exposure to Probiotic Aliivibrio spp.

Applied Microbiology, 2023
Salmon lice (Lepeophtheirus salmonis) constitute a major challenge during the production of farmed Atlantic salmon in Norway. Preventive measures are considered to have a higher impact on sustainable control than lice treatment.

Factors associated with changing efficacy of emamectin benzoate against infestations of Lepeophtheirus salmonison Scottish salmon farms

, 2008
The availability and use of medicines to control infestations of sea lice on Atlantic salmon, Salmosalar L., farms in Scotland has changed considerably in the last decade (Lees, Gettinby & Revie 2008b).

Comparative tests of ectoparasite species richness in seabirds [PDF]

, 2007
Background: The diversity of parasites attacking a host varies substantially among different host species. Understanding the factors that explain these patterns of parasite diversity is critical to identifying the ecological principles underlying ...

Effects of Vector Density on Blood Parasite Spread and Health Consequences for Avian Hosts: An Experimental Epidemiology Blueprint

Integrative Zoology, EarlyView.
In an experimental epidemiology setup, groups of pigeons were exposed to different numbers of infective malaria vectors. Vector number explained the speed of transmission, the final prevalence, and changes in host behavior. ABSTRACT Vector density plays a critical role in the transmission dynamics of vector‐borne diseases and thus in their health and ...
