origin of this species is in Asia; in its initial habitat larvae
are found in small tree-holes filled with water, but in addition
this species shows adaptation to small artificial man-made breeding
sites; this habitat preference and the capability of eggs to withstand
low temperatures or desiccation facilitated the distribution of
S. albopicta throughout the world to all continents by
being transported in used-tire containers; as yet the species is
recorded in several European countries (Albania, Italy, France,
Belgium) (Schaffner et al. 2001, Becker et al. 2003).
are dendrolimnic and naturally found in small tree-holes, bamboo
stumps, coconut shells, rock holes or palm fronds, filled with water;
furthermore the species shows a capacity to colonise various artificial
breeding sites like sewer manholes, flower vases, tin cans, glass
bottles, discarded motor vehicle tyres or other small containers
(Huang 1972). This high ecological plasticity allows the colonisation
of different environments, such as forests, rural villages or peri-urban
areas, in tropical as well as in temperate regions (Schaffner et
albopicta is a multivoltine species (Becker et al. 2003). In
the field a maximum of five generations per year has been recorded.
These generations overlap due to delayed hatching and to the breeding
sites' heterogeneity; the eggs, resistant to cold and desiccation,
are laid above the water surface, preferentially on dark and rough
substrate; a rise in water level will induce the hatching of young
larvae; larvae and adults can be found from April-May till November;
hibernation takes place during the egg-stage (Schaffner et al. 2001).
feed on humans, mammals, birds, batrachians and reptiles, depending
on host presence; they bite during the day, rarely at night and
preferably inside dwellings (Schaffner et al. 2001, Becker et al.
albopicta is a vector of dengue and filariasis (Becker et al.
2003). In nature it has been found infected with diverse viruses
including West Nile; in laboratory studies it could be infected
with numerous viruses (Schaffner et al. 2001).
