Louse (Insecta : Phthiraptera) mitochondrial 12S rRNA secondary structure is highly variable [PDF]

, 2002
Lice are ectoparasitic insects hosted by birds and mammals. Mitochondrial 12S rRNA sequences obtained from lice show considerable length variation and are very difficult to align.

First report of reduced sensitivity towards hydrogen peroxide found in the salmon louse Lepeophtheirus salmonis in Norway

Aquaculture Reports, 2015
Reduced sensitivity towards chemotherapeutants in the salmon louse Lepeophtheirus salmonis (Krøyer) is an increasing problem for the fish farming industry.

Caligus rogercresseyi acetylcholinesterase types and variants: a potential marker for organophosphate resistance

Parasites & Vectors, 2018
Background Control of the sea louse Caligus rogercresseyi in the Chilean salmonid industry is reliant on chemical treatments. Azamethiphos was introduced in 2013, although other organophosphates were previously used.

Salmon lice loads on Atlantic salmon smolts associated with reduced welfare and increased population mortalities

Aquaculture Environment Interactions, 2023
Modelling potential impacts of salmon lice Lepeophtheirus salmonis on Atlantic salmon Salmo salar requires estimation of the levels that cause serious sub-lethal physiological impacts and direct mortality.

Phenylalanine Hydroxylase RNAi Knockdown Negatively Affects Larval Development, Molting and Swimming Performance of Salmon Lice

Frontiers in Marine Science, 2020
Phenylalanine hydroxylase (PAH) is a crucial enzyme involved in tyrosine biosynthesis, having roles in neurological and physiological processes. The purpose of PAH has received little attention in crustaceans despite extensive investigations in other ...

Space-time modelling of the spread of salmon lice between and within Norwegian marine salmon farms. [PDF]

PLoS ONE, 2013
Parasitic salmon lice are potentially harmful to salmonid hosts and farm produced lice pose a threat to wild salmonids. To control salmon lice infections in Norwegian salmonid farming, numbers of lice are regularly counted and lice abundance is reported ...

Data incongruence and the problem of avian louse phylogeny [PDF]

, 2004
Recent studies based on different types of data (i.e. morphological and molecular) have supported conflicting phylogenies for the genera of avian feather lice (Ischnocera: Phthiraptera).

Salmon louse labial gland enzymes: implications for host settlement and immune modulation

Frontiers in Genetics
Salmon louse (Lepeophtheirus salmonis) is a skin- and blood-feeding ectoparasite, infesting salmonids. While feeding, labial gland proteins from the salmon louse may be deposited on the Atlantic salmon (Salmo salar) skin.

Sea lice prevention strategies affect cleaner fish delousing efficacy in commercial Atlantic salmon sea cages

Aquaculture Environment Interactions, 2020
Over the last 2 decades, cleaner fishes have been employed to remove external sea lice parasites from Atlantic salmon Salmo salar in sea cages. Norway, Scotland, Ireland, and the Faroe Islands combined now use ~60 million cleaner fish per year.
