Abstract:

Ectoparasitism is the most devastating parasitic condition of poultry after coccidiosis. The present study was conducted to identify the risk factors associated with avian ectoparasitism in Osun State, Nigeria. Data was obtained from avian species presented at the major Veterinary Hospitals in Osun State between January 2006 and December 2015. A total of 4,584 avian species were presented in the period under review. Of the presented birds, 2,665 (58.14%) were young, while 1,919 (41.86%) were adults. One thousand nine hundred and ninety four (43.50%) were male and 2,590 (56.50%) were female. Mo

PURPOSE: This study aimed to investigate the influence of sex, age, and body condition on the prevalence and intensity of ectoparasitic infestations in goats, focusing on lice and fleas, and to identify significant associations between these factors. METHODS: The study was conducted on 4,599 goats examined between May 2018 and November 2019. The animals were classified by sex, age (young < 2 years; adult ≥ 2 years), and body condition (good, fair, or poor). Ectoparasites were collected and identified in the laboratory, and infestation intensity (II) and degree of infestation (DI) were asses

The unpredictable outcomes of these treatments in some animals can be associated with undesirable consequences and there is a lack of knowledge surrounding their use.

Ectoparasites present a global challenge to animal health, affecting a wide range of species. These parasites can infect both animals and humans, leading to significant health issues. The impact of ectoparasites extends beyond health, as they can also reduce the productivity of livestock. Moreover, many ectoparasite species act as vectors for bacterial, viral, or parasitic pathogens, thereby posing significant risks to human and animal health. Historically, agents such as organochlorides, organophosphates, carbamates, insect growth regulators, neonicotinoids, spinosad, fipronil, avermectins, i

Abstract:

A study of head lice infestations among young people, adults and elderly individuals was conducted from August 2010 to July 2013 in Manaus, AM, Northern Brazil. Hair samples collected from 1,860 individuals in 18 barber shops and beauty parlors were examined for the ectoparasite. The occurrence of pediculosis and its association with factors, such as sex, age, ethnicity, hair characteristics and the socioeconomic profile of salon customers, salon location and seasonal variation were determined. The overall occurrence rate was 2.84%. Occurrence was higher in hair samples from non-blacks and the

Abstract:

Background Managed, feral and wild populations of European honey bee subspecies, Apis mellifera, are currently facing severe colony losses globally. There is consensus that the ectoparasitic mite Varroa destructor, that switched hosts from the Eastern honey bee Apis cerana to the Western honey bee A. mellifera, is a key factor driving these losses. For >20 years, breeding efforts have not produced European honey bee colonies that can survive infestations without the need for mite control. However, at least three populations of European honey bees have developed this ability by means of natu

When juvenile yellowtail (Seriola quinqueradiata) fed diets containing silkrose were artificially infected with Benedenia seriolae, a fish ectoparasite, the numbers of parasitized B. seriolae were significantly lower compared to that in fish in the control group without silkrose treatment. Furthermore, when juvenile yellowtails were severely infected with B. seriolae, no mortality was observed in the silkrose-treated group, compared to more than 60% in the control group.

Abstract:

A model of ectoparasitic reproductive strategies is presented. To be successful, an ectoparasite must either disperse to find a new host or stay on one host and produce its progeny during the lifetime of the host. Dispersion is facilitated by utilizing many host species and by waiting for the next host; these strategies prolong the generation time. Staying on the host is facilitated by shortening the generation time. Ectoparasites that repeatedly move on and off hosts are thus expected to have wide host preference spectra and long generation times while sedentary ectoparasites are expected to
