[Problems posed by the spread of Aedes albopictus]

Area of Science:

• Entomology
• Invasive Species Biology
• Public Health

Context:

• The Asian tiger mosquito, Aedes albopictus, is native to Southeast Asia and recognized as a natural vector for dengue.
• Over the past decade, this mosquito has rapidly expanded its geographic range worldwide, establishing populations in the Americas, Pacific islands, Africa, and Europe.
• Introduction events are strongly linked to the international trade of used tires, which serve as a primary vehicle for transporting eggs and larvae.

Purpose:

• To document the global spread of Aedes albopictus.
• To identify the primary mechanism of introduction and expansion.
• To highlight the ecological adaptability and public health implications of this invasive mosquito.

Summary:

• Aedes albopictus has established populations across multiple continents, including North and South America, Australia, Africa, and Europe.
• The international trade in tires is a critical factor facilitating the global dispersal of Aedes albopictus.
• This mosquito species exhibits a wide ecological tolerance, thriving in both tropical and temperate climates, and has been observed to displace native mosquito species like Aedes aegypti in some regions.

Impact:

• The widespread distribution of Aedes albopictus increases the risk of arbovirus transmission, including dengue, Zika, and chikungunya, in newly invaded areas.
• The displacement of native mosquito species by Aedes albopictus can alter local disease transmission dynamics.
• Effective control strategies targeting the tire trade are crucial to mitigate the continued global expansion of this medically important insect vector.
