The relationship of ectoparasite prevalence to the capturing season, locality and species of the murin rodent hosts in Iran

Persian Journal of Acarology, 2015
The role of rodents in transmission of different parasitic infections, has been well documented. The objective of this study was to determine the relationship between capturing season and rodent habitat with ectoparasites prevalence in the murin rodents

Sex‐Specific Control and Incomplete Matings: Sperm Removal Behavior in a Bush Cricket Species

Ethology, EarlyView.
In this study, we investigated which sex influences the duration of sperm removal behaviour (SRB) in the ornate bush cricket, Metaplastes ornatus. Female traits showed a weak effect on SRB duration, and lighter females mated more frequently. Frequent unsuccessful mating terminations shortened SRB indicating high level of sexual conflict.

Evaluating Electric Harps and Muzzles to Mitigate the Impact of Vespa velutina nigrithorax at Beehives

Journal of Applied Entomology, EarlyView.
ABSTRACT The Asian hornet (Vespa velutina nigrithorax) poses a significant threat to the beekeeping industry. Using an experimental apiary of 36 hives, we simultaneously evaluated the effectiveness of two mitigation measures—muzzles and electric harps—in reducing the impact of Asian hornets on honey bee colonies.

Using host species traits to understand the consequences of resource provisioning for host–parasite interactions [PDF]

, 2017
1.Supplemental food provided to wildlife by human activities can be more abundant and predictable than natural resources, and subsequent changes to wildlife ecology can have profound impacts on host–parasite interactions.

Shedding light on the parasite communities and diet of the deep‐sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay)

Journal of Fish Biology, EarlyView.
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Anemia, leukocytosis and eosinophilia in a resource-poor population with helmintho-ectoparasitic coinfection

Journal of Infection in Developing Countries, 2010
Introduction: Eosinophilia and anemia are very common hematological alterations in the tropics but population-based studies scrutinizing their value for diagnosing parasitic infections are rare.

Controlling Ectoparasites on Welsh Organic Sheep Farms [PDF]

, 2003
1. Organophosphate (OP) based dips offer a broad spectrum control against all major ectoparasites in the UK. However, there is continuing controversy over the safety to dip operators and the environment. The use of OPs is prohibited by organic standards,

Physiological responses of reared sea bream (Sparus aurata Linnaeus, 1758) to an Amyloodinium ocellatum outbreak [PDF]

, 2017
Amyloodiniosis represents a major bottleneck for semi-intensive aquaculture production in Southern Europe, causing extremely high mortalities. Amyloodinium ocellatum is a parasitic dinoflagellate that can infest almost all fish, crustacean and bivalves ...

Looking for Greener Pastures: In Vitro Screening of Phytogenics for the Control of Sparicotyle chrysophrii in Gilthead Sea Bream

Journal of Fish Diseases, EarlyView.
ABSTRACT The gill parasite Sparicotyle chrysophrii poses a significant threat to gilthead sea bream (Sparus aurata) aquaculture in the Mediterranean, causing considerable mortality and economic losses. As traditional chemotherapeutic treatments, like formalin, face growing regulatory restrictions, there is an urgent need for alternative control ...
