Aedes albopictus, an arbovirus vector: From the darkness to the light
In the last 30 years, the Asian tiger mosquito, Aedes albopictus, has spread dispersed worldwide and has recently been presented as a efficient vector of Chikungunya virus (CHIKV). The authors review the current geographic range and the relevant biological traits of A. albopictus in order to explain its rapid spread.

In the last 30 years, the Asian tiger mosquito, Aedes albopictus, has spread dispersed worldwide and has recently been presented as a efficient vector of Chikungunya virus (CHIKV). The authors review the current geographic range and the relevant biological traits of A. albopictus in order to explain its rapid spread. They discuss recent changes in its role as a vector and its importance in the current and future emergence of pathogens.
ECDC comment: 2009-07-17This review is very useful to understand why several countries in Europe are susceptible for Ae. albopictus transmitted diseases, particularly Italy, where the mosquitoes are active from February through December, with a peak in August and September. CHIKV implantation and spread with the arrival of travelers with high CHIKV viremia became reality in Italy with the outbreak which developed in summer 2007. The presumed index case was a man returned from India. Chikungunya outbreaks have been recently described in South-eastern Asia. Therefore future imported cases and European outbreaks are expected. Interstingly, the authors report conventional and innovative ways to control A. albopictus.

Surveillance of the chikungunya vector Aedes albopictus (Skuse) in Emilia-Romagna (northern Italy): organizational and technical aspects of a large scale monitoring system
The chikungunya virus outbreak that occurred in 2007 in northern Italy (Emilia-Romagna region) prompted the development of a large scale monitoring system of the population density of Aedes albopictus (Skuse, 1894), comparable at the provincial and municipal levels. In 2007, egg density data presented an aggregated distribution (VMR &gt;1) and Taylor's power law was applied to calculate the minimum number of ovitraps needed to obtain the prefixed precision levels: D=0.2 in the areas where the chikungunya epidemic occurred and D=0.3 in all the other urban areas &gt;600 ha.Read more
