The ectoparasite Lepeophtheirus salmonis has for decades been a serious challenge to the sustainability of salmonid aquaculture and potential disrupt ecosystem wild salmonids. To tackle this challenge, efforts have made develop effective lice control strategies that deter ectoparasitic infestations on salmon farms. Infestation can be enhanced by understanding L. population dynamics may reveal c...

BACKGROUND Intestinal infestations are of considerable public health importance in Zambia and elsewhere in Africa. Children aged less than 5 years are at the highest risk of infection. Interventions for prevention and control of these infestations require identification of their determinants. This study investigates the determinants of intestinal infestations in children below 5 years of age ad...

We examined bed bug prevalence in 2,372 low-income apartments within 43 buildings in four New Jersey cities using a combination of resident interviews, brief visual inspections, and monitoring with Climbup Insect Interceptors. Infestation rates ranged from 3.8 to 29.5% among the buildings, with an overall infestation rate of 12.3%. Within each apartment, the bed area trapped significantly more ...

To evaluate the relative influence of ecological and management factors on the probability of detecting cattle-fever tick (Boophilus microplus and Boophilus annulatus) infestations in rotational grazing systems, we adapted a simulation model of Teel et al. [J. Range Manage. 51 (1998) 501] that examines interactions among Boophilus ticks, cattle, and habitat type under rotational grazing systems...

Worm infestations influence the immune system and may therefore decrease the risk for autoimmune diseases. The aim of the study was to determine whether children who have developed autoimmune disease were less likely to have had worm infestations in childhood. The ABIS-study is a prospective population-based cohort study of children born in southeast Sweden 1997/99. 17.055 children participated...

Heritable bacterial endosymbionts play an important role in aphid ecology. Sequence-based evidence suggests that facultative symbionts such as Hamiltonella defensa or Regiella insecticola also undergo horizontal transmission. Other than through male-to-female transfer during the sexual generation in autumn, the routes by which this occurs remain largely unknown. Here, we tested if parasitoids o...

Date palm cultivation is economically important in the Sultanate of Oman, with significant financial investment coming from both the government and from private individuals. However, a global infestation of Dubas bug (Ommatissus lybicus Bergevin) has impacted the Middle East region, and infestations of date palms have been widespread. In this study, spatial analysis and geostatistical technique...

Scabies is a worldwide disease and a major public health problem in many developing countries, related primarily to poverty and overcrowding. In remote Aboriginal communities in northern Australia, prevalences of up to 50% among children have been described, despite the availability of effective chemotherapy. Sarcoptic mange is also an important veterinary disease engendering significant morbid...
