Presently, 45% of the total human population of Europe, as well as their domestic and companion animals, are exposed to the risk of vector-borne helminths (VBH) causing diseases. A plethora of intrinsic biological and extrinsic factors affect the relationship among helminths, vectors and animal hosts, in a constantly changing environment. Although canine(More)
The recent notifications of autochthonous cases of dengue and chikungunya in Europe prove that the region is vulnerable to these diseases in areas where known mosquito vectors (Aedes albopictus and Aedes aegypti) are present. Strengthening surveillance of these species as well as other invasive container-breeding aedine mosquito species such as Aedes(More)
To enable a better understanding of the overwhelming alterations in the invasive mosquito species (IMS), methodical insight into the population and environmental factors that govern the IMS and pathogen adaptations are essential. There are numerous ways of estimating mosquito populations, and usually these describe developmental and life-history parameters.(More)
Field studies were conducted in the Upper Rhine Valley to determine the responses of mosquitoes to CDC traps baited with either CO2, octenol, light or paired combinations of these. Among eight mosquito species caught, the attractant effect on trap catches was studied in the four most abundant: Aedes vexans, Ae.rossicus, Ae.cinereus and Culex pipiens. Traps(More)
Environmental factors influence the effectiveness of microbial control agents in mosquito control programs. Four of these factors (water temperature, larval density, sunlight and the effect of associated filter feeders) were studied with Bacillus thuringiensis var. israelensis under laboratory and semifield conditions in Europe using different instars of(More)
The influence of larval cadavers of Culex pipiens on recycling processes of Bacillus sphaericus was investigated by bioassays and spore counts in the laboratory. Studies conducted with 3 different B. sphaericus concentrations (0.005, 0.01, 0.05 mg B. sphaericus/liter) indicated that the presence of cadavers in the water contributed to the maintenance of(More)
A convenient, electronically controlled, in situ, membrane feeding system is described. Evaluation of the system for feeding single pair-mated Aedes aegypti with defibrinated, refrigerated pig blood indicated no significant difference from mouse-fed controls in rat of egg maturation, fecundity, or pupal yield. The feeding system is also suitable for use(More)
Mass production is an important co mponent of any pest or vector control program that requires the release of large number of insects. As part of efforts to develop an area-wide program involving the sterile insect technique (SIT) for the control of mosquitoes, the Insect Pest Control Laboratory of the Food and Agriculture Organization-International Atomic(More)
BACKGROUND Among the arthropod-borne nematodes infesting dogs, Onchocerca lupi (Spirurida: Onchocercidae) is of increasing zoonotic concern, with new human cases of infection diagnosed in Turkey, Tunisia, Iran and the USA. Knowledge of the biology of this nematode is meagre. This study aimed at assessing the distribution and periodicity of O. lupi(More)
West Nile virus (WNV) represents a serious burden to human and animal health because of its capacity to cause unforeseen and large epidemics. Until 2004, only lineage 1 and 3 WNV strains had been found in Europe. Lineage 2 strains were initially isolated in 2004 (Hungary) and in 2008 (Austria) and for the first time caused a major WNV epidemic in 2010 in(More)
