Behaviour and Dispersal of Mobile Salmon Lice When Detached From the Host

Journal of Fish Diseases, Volume 48, Issue 11, November 2025.
ABSTRACT Sea lice can flourish when salmon are farmed in open sea‐cages, necessitating treatments to control outbreaks and reduce larval export. However, mobile ectoparasitic stages can be dislodged during crowding or other procedures, and potentially reinfest farmed or wild fish.

Comparative immune responses against Psoroptes ovis in two cattle breeds with different susceptibility to mange [PDF]

, 2015
The sheep scab mite, Psoroptes ovis, is a major problem in the beef cattle industry, especially in Belgian Blue (BB) cattle. This breed is naturally more predisposed to psoroptic mange but reasons for this high susceptibility remain unknown.

Variation in Small Mammal Species Composition and the Occurrence of Parasitic Mites in Two Landscapes in a Scrub Typhus Endemic Region of Western Yunnan Province, China

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Yunnan Province, the most serious scrub typhus endemic areas in China, provides abundant ecological resources that sustain parasite and host populations. The distribution of vector‐borne diseases is driven by interactions between hosts, vectors and the environment, revealing critical ecological dynamics.

Cell size and Varroa destructor mite infestations in susceptible and naturally-surviving honeybee (Apis mellifera) colonies

Apidologie, 2019
The ectoparasitic mite Varroa destructor is a key threat for European honeybee subspecies (Apis mellifera) globally. However, some A. mellifera populations are known to survive mite infestations by means of natural selection (naturally surviving), likely

Prevalence and risk factors associated with ectoparasite infestation of buffaloes in an Amazonian ecosystem

Parasites & Vectors, 2018
Background The water buffalo (Bubalus bubalis) is well adapted in some regions of the Amazon. Of all Brazilian states, Pará contains the largest number of this species, with 510,000 animals, approximately 38% of the Brazilian buffaloes.

Concurrent Parasitism Alters Thermoregulation in Honey Bee (Hymenoptera: Apidae) Winter Clusters [PDF]

, 2017
Thermoregulation is crucial for honey bee, Apis mellifera L. (Hymenoptera: Apidae), colony survival in temperate regions, but possible interference by parasites is currently unknown. The small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae),

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

, 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.
