albopictus

Aedes albopictus, commonly known as the Asian tiger mosquito, is a widespread mosquito species in the family Culicidae. It is easily recognized by its characteristic black and white striping on the body and legs. Native to Southeast Asia, it has become one of the world’s most invasive mosquito species, establishing populations in many parts of North America, Europe, Africa, and other regions through global trade and the movement of used tires and other containers that collect water.

Ecology and life cycle: Aedes albopictus is a container breeder. Females lay eggs on the inner walls of water-holding containers; the eggs can withstand desiccation and hatch when the container floods. Larvae and pupae develop in stagnant or slow-moving water, including natural containers like tree holes as well as artificial ones such as buckets, flower pots, and discarded tires. Adults are primarily day-biting, with peak activity in the early morning and late afternoon, and they readily rest in shaded vegetation or built environments. The life cycle from egg to adult can be completed in as little as one to two weeks in warm conditions.

Public health significance: The species is a competent vector for several arboviruses, including dengue, chikungunya, and Zika, among others. Local transmission has occurred in regions outside its native range, particularly in areas with suitable climate and high human-mosquito contact. The public health impact depends on environmental conditions and the presence of susceptible human populations.

Control and management: Strategies focus on reducing standing water and eliminating breeding sites, coupled with targeted use of larvicides and, during outbreaks, adulticides. Additional measures include personal protection against bites and, in some programs, innovative approaches such as biological control, Wolbachia-based methods, and sterile insect techniques to disrupt transmission.
