Resumo: During the past decade Aedes albopictus (Skuse) has extended its range to parts of North and South America, the Caribbean, Africa, southern Europe, and some Pacific Islands previously free of such infestations. This remarkably rapid spread of a mosquito species is unprecedented during this century and has heightened concern among public health and vector control officials because of the known and potential vector relationships of Ae. albopictus with several arboviruses. Photoperiod, temperature, rainfall, and humidity are major limiting factors affecting the range extension of Ae. albopictus. These are examined, along with previous distribution records of the closely related Aedes aegypti (Linnaeus), to identify general Areas of the Mediterranean basin that might be suitable for colonization by Ae. albopictus. Finally, the results of vector competence studies, virus isolation tests of field-collected specimens, and feeding habits of Ae. albopictus are analyzed with a view toward assessing the potential of Ae. albopictus becoming involved in arbovirus cycles in Mediterranean countries. Mosquito-borne arboviruses of concern to the region include Sindbis, chikungunya, West Nile, dengue, Tahyna, Rift Valley fever, and Batai viruses. In addition, Israel turkey meningoencephalitis and African horse sickness viruses occur in the Area and mosquito vectors may be involved in their transmission.
