“…As the availability of water is an important driver of mosquito population dynamics, both mosquito abundance and RVF suitability were expected to be higher in the vicinity of permanent rivers and lakes. Active dispersal distance is short for most mosquito species (<1 km) (Harrington et al., ; Yamar et al., ; Krida et al., ), but other studies conducted in temperate regions on potential RVFv species (listed below) report larger distances (Brust, ; Bogojević et al., ). Therefore, we considered a linear decreasing relationship between both enzootic and epizootic suitability for RVF and distances from permanent water sources (with maximum and minimum thresholds at 0 and 10 km, respectively) (Table ).…”

Rift Valley fever (RVF) is a vector-borne zoonotic disease that has caused widespread outbreaks throughout Africa and the Arabian Peninsula, with serious consequences for livestock-based economies and public health. Although there have never been any reports of RVF in Morocco, Algeria, Tunisia and Libya, it is a priority disease in the Maghreb, due to the threat of introduction of the virus through transboundary livestock movements or infected mosquito vectors. However, the implementation of surveillance activities and early warning contingency plans requires better knowledge of the epidemiological situation. We conducted a multicriteria decision analysis, integrating host distribution with a combination of important ecological factors that drive mosquito abundance, to identify hotspots and suitable time periods for RVF enzootic circulation (i.e. stable transmission at a low to moderate level for an extended period of time) and an RVF epizootic event (i.e. a sudden occurrence of a large number of infected animals over a large geographic area) in the Maghreb. We also modelled vector species distribution using available information on vector presence and habitat preference. We found that the northern regions of the Maghreb were moderately suitable for RVF enzootics, but highly suitable for RVF epizootics. The vector species distribution model identified these regions as the most favourable mosquito habitats. Due to the low density of animal hosts and arid conditions, the desert region showed low RVF suitability, except in oases. However, the presence of competent vectors in putative unsuitable areas underlines the need for further assessments of mosquito habitat preference. This study produced monthly RVF suitability maps useful for animal health managers and veterinary services involved in designing risk-based surveillance programmes. The suitability maps can be further enhanced using existing country-specific sources of information and by incorporating knowledge - as it becomes available - on the epidemiology of the disease and distribution of vectors in the Maghreb.

“…In other testing of Mosquito Magnets over the past 5 years, Culex Environmental has found that the placement of these traps is a key factor in maximizing catches. Dispersal patterns of emerging adult mosquitoes vary between species (Bogojević et al 2010), and adults are rarely evenly distributed across the landscape, often following prevailing winds for distances upwards of 10 km after emergence (Brust 1980). Many mechanical devices, including Mosquito Magnets, have the added capacity of utilizing octenol (1-octen-3-ol) as an attractant, which has been found to improve trapping success in many studies (Kline 2006, Qualls and Mullen 2007, Li et al 2010.…”

In this study, we explore the potential of a commercially available mechanical mosquito control device, the Liberty Plus Mosquito Magnet (hereafter referred to as Mosquito Magnet), to reduce the abundance of adult nuisance mosquito populations in public recreational areas. Mosquitoes were trapped on 2 replicate sites close to a campground at Brae Island Regional Park near Fort Langley, British Columbia, Canada. Each site comprised a treatment (Mosquito Magnets used) and control subsection (Mosquito Magnets not used). Mosquito numbers were assessed before and after the treatment period in both subsections at each site with Centers for Disease Control and Prevention (CDC) black light traps. Although nearly 200,000 mosquitoes from 14 different species were collected over 366 trap-nights from May 31 to July 31, 2008, the majority of those identified were Aedes sticticus (68%) and Ae. vexans (22%)-2 of the most notorious nuisance mosquito species in British Columbia. The number of mosquitoes captured by CDC black light traps increased overall during the study period due to natural seasonal variation. Nevertheless, a significant treatment effect (P = 0.0389) was associated with an average decrease of about 32% in the average number of adult mosquitoes collected per day. These results strongly suggest that Mosquito Magnets can reduce the abundance of nuisance mosquitoes, potentially reducing the biting pressure on the public, and providing another tool in mosquito control operations.

“…In the present study, a distance of 3500 m was assumed, because the Aedes and Anopheles mosquitoes have an average MFD of 3500 m (Verdonschot & Besse-lototskaya, 2014). Areas located closer than 3.5 km from the mosquito breeding pools were considered as high hazard zones; however, some studies report that under some circumstances, mosquitos may fly up to 10 km (Bogojevic, Merdic, & Bogdanovic, 2011). Thus, areas located closer than 10 km from the mosquito breeding pools were considered as low hazard zones.…”

Flood hazard is usually assessed based on the hydrodynamic characteristic of flood (water depth and velocity); however, in riverine floodplains, flood events last for several days. In such cases, the long exposure to flood water may cause additional health problems. Nevertheless, usually flood hazard studies do not consider possible hazards due to flood duration. This paper presents a flood hazard assessment methodology for considering flood duration and exposure to vectorborne diseases, and compares flood hazard maps that include and neglect flood duration. Results from a two-dimensional hydrodynamic flood simulation combined with entomological concepts identify any mosquito-breeding pools. Proximity analyses based on mosquito flying range define the areas exposed to mosquitos; hence, to vector-borne diseases. Results were compared with the probability of mosquito occurrence, showing that solely the consideration of flood depth hazard leads to a false flood hazard assessment, under-predicting the flood hazard. Important cities and areas initially considered safe zones may be exposed to health hazards, due to flood duration. Inclusion of flood duration improves flood hazard assessment; hence, improves flood management plans. Maximum flood depth for oviposition (MFDO) and minimum flood duration (MFD) are important variables for defining mosquito-breeding pools. MFDO is the most uncertain variable. Discussion includes advantages in flood hazard assessment and present methodological limitations.Análisis de exposición a enfermedades vectoriales por la duración de inundación para una evaluación más completa de amenazas por inundación: Llanuras de Moxos, Bolivia RESUMENLas amenazas por inundaciones generalmente son evaluadas en base a las características hidrodinámicas de la inundación: profundidad y velocidad. Sin embargo, en planicies de inundación, las inundaciones pueden llegar a durar varios días. En tales casos la exposición prolongada al agua inundada puede generar problemas de salud. Sin embargo, generalmente los estudios de inundación no consideran las amenazas debido a la duración de la inundación. El presente artículo presenta una metodología para evaluar amenazas de inundación considerando la duración de la inundación y la exposición a enfermedades transmitidas por vectores, y realiza una comparación entre mapas de amenaza por inundación, tanto incluyendo y sin incluir duración. Los resultados de una simulación hidrodinámica de dos dimensiones fueron combinados con conceptos de entomología, a fin de identificar criaderos de mosquitos. Luego, se realizó un análisis de proximidad basado en sus distancias de vuelo, a fin de identificar las zonas expuestas a mosquitos; y por lo tanto, expuestas a enfermedades vectoriales. Los resultados fueron comparados con la probabilidad de ocurrencia de mosquitos. Considerar solo la profundidad de inundación hace subestimar las amenazas por inundación. Importantes zonas urbanas que inicialmente eran consideradas como zonas seguras pueden estar expuestas a amenazas ...
