Aedes aegypti is the urban vector of dengue viruses worldwide. While climate influences the geographical distribution of this mosquito species, other factors also determine the suitability of the physical environment. Importantly, the close association of A. aegypti with humans and the domestic environment allows this species to persist in regions that may otherwise be unsuitable based on climatic factors alone. We highlight the need to incorporate the impact of the urban environment in attempts to model the potential distribution of A. aegypti and we briefly discuss the potential for future technology to aid management and control of this widespread vector species.

    • "Aedes species have historically expanded their global distribution in association with humans (Tabachnick and Powel 1979), exploiting the ability of having dryresistant eggs that can be carried with commodities around the globe. The invasive mosquito species (IMS) Aedes albopictus (Skuse) (¼ Stegomyia albopicta sensu Reinert et al. 2004) has experienced a dramatic global expansion facilitated by human activities, in particular the movement of used tires and " lucky bamboo " (Paupy et al. 2009), and over the past 25 yr, there has been an increase in the worldwide distribution of the yellow fever vector Aedes aegypti (L.) (¼ Stegomyia aegypti sensu Reinert et al. 2004) (Jansen and Beebe 2010). From the 2000s decade, Europe has witnessed several outbreaks of mosquito-borne diseases. "

    ABSTRACT: Since 2009, The Netherlands Food and Consumer Product Safety Authority carries out surveys focusing on, amongst others, the presence of invasive mosquito species (IMS). Special attention is given to exotic container-breeding Aedes species Aedes aegypti (L.), Aedes albopictus (Skuse), Aedes atropalpus (Coquillett), and Aedes japonicus japonicus (Theobald). This study describes the implementation of real-time PCR tests described by Hill et al. (2008) for the identification of Ae. aegypti and Ae. albopictus, and the development of two novel real-time PCR tests for the identification of Ae. atropalpus and Ae. j. japonicus. Initial test showed that optimization of elements of the Ae. aegypti and Ae. albopictus tests was needed. Method validation tests were performed to determine if the implemented and newly developed tests are fit for routine diagnostics. Performance criteria of analytical sensitivity, analytical specificity, selectivity, repeatability, and reproducibility were determined. In addition, experiments were performed to determine the influence of environmental conditions on the usability of DNA extracted from mosquito specimens trapped in BG-Sentinel traps. The real-time PCR tests were demonstrated to be sensitive, specific, repeatable, reproducible, and are less prone to false negative results compared to partial cytochrome c oxidase I gene sequencing owing to the DNA fragmentation caused by environmental influences.

    • "Ae. aegypti prefers human habitations as they provide resting and host seeking possibilities (Weaver & Reisen, 2009). The species will readily enter buildings (Jansen & Beebe, 2010; Reiter, 2010), and its activity is both diurnal and crepuscular (Turell et al., 2005; Jansen & Beebe, 2010). "

    ABSTRACT: Among the invasive mosquitoes registered all over the world, Aedes species are particularly frequent and important. As several of them are potential vectors of disease, they present significant health concerns for 21st century Europe. Five species have established in mainland Europe, with two (Aedes albopictus and Aedes japonicus) becoming widespread and two (Ae. albopictus and Aedes aegypti) implicated in disease transmission to humans in Europe. The routes of importation and spread are often enigmatic, the ability to adapt to local environments and climates are rapid, and the biting nuisance and vector potential are both an ecomonic and public health concern. Europeans are used to cases of dengue and chikungunya in travellers returning from the tropics, but the threat to health and tourism in mainland Europe is substantive. Coupled to that are the emerging issues in the European overseas territorities and this paper is the first to consider the impacts in the remoter outposts of Europe. If entomologists and public health authorities are to address the spread of these mosquitoes and mitigate their health risks they must first be prepared to share information to better understand their biology and ecology, and share data on their distribution and control successes. This paper focusses in greater detail on the entomological and ecological aspects of these mosquitoes to assist with the risk assessment process, bringing together a large amount of information gathered through the ECDC VBORNET project.

    • "In the academic article [13], author has exhibited one of the controlling strategies named Sterile Insect Technique (SIT) for the control of Aedes aegypti mosquitoes. Further, RIDL (Release of Insects Carrying a Dominant Lethal) based on new genetic sexing system for male mosquitoes is introduced by which allow only to born of male mosquitoes by blocking of female production of Aedes aegypti [20]. As a cost effective methods most countries use high toxic chemicals such as Malathion and insecticides to control mosquito population which are very dangerous for public health. "

    ABSTRACT: This article presents a new eco-epidemiological deterministic delay differential equation model considering a biological controlling approach on mosquitoes, for endemic dengue disease with variable host (human) and variable vector (Aedes aegypti) populations, and stage structure for mosquitoes. In this model, predator-prey interaction is considered by using larvae as prey and mosquito-fish as predator. We give a complete classification of equilibria of the model, and sufficient conditions for global stability/global attractivity of some equilibria are given by constructing suitable Lyapunov functionals and using Lyapunov-LaSalle invariance principle. Also, numerical simulations are presented to show the validity of our results.
