? What is the Asian tiger mosquito
Scientific name: Aedes albopictus
Family: Culicidae
Order: Diptera
Risk level: Very high
Category: Flying pest
The Asian tiger mosquito (Aedes albopictus) shares Aedes aegypti’s reputation as a vector of dengue, chikungunya and Zika, but adapts to a much wider range of environments. It lives in both rural and urban areas and tolerates lower temperatures, giving it a broader geographic range. A single silver stripe along its back distinguishes it from A. aegypti.
Life cycle of the Asian tiger mosquito
Mosquitoes undergo complete metamorphosis: egg, larva (four aquatic instars), aquatic pupa and adult. Larvae and pupae are entirely aquatic. In hot weather, a generation takes 7–14 days. Only the female takes blood meals, which are needed for egg development; males feed only on nectar.
Distribution of the Asian tiger mosquito
It is widespread in tropical and subtropical regions. In Saudi Arabia, the Gulf and Egypt, it occurs in different types of standing or warm water.
Damage and risks associated with the Asian tiger mosquito
It can transmit dengue (secondarily to A. aegypti), chikungunya (the primary vector in the African epidemic), Zika and Italian encephalitis in Europe. It does not transmit yellow fever.
Signs of an Asian tiger mosquito infestation
Signs include increasing numbers of adults in traps and larvae in standing water.
Where Asian tiger mosquitoes are found
They use the same containers as Aedes aegypti but accept a wider range of sites, including rotting leaves, tree cavities and other natural areas.
Asian tiger mosquito control methods
Survey and remove breeding sources (standing water). Use ULV fogging to control adults, biological larvicides (Bti) in standing water, and biological control with Gambusia fish.
Asian tiger mosquito control products
Use pyrethroids (deltamethrin and permethrin) to spray adults, Bti for biological larval control, and DEET/thiamethoxam for personal protection.
Requirements for controlling Asian tiger mosquitoes in food facilities
FSSC 22000/BRCGS: mosquitoes pose a high risk in food facilities. Standing water around the facility must be managed, and ILTs and protective window screens installed.
A fact about the Asian tiger mosquito
The Asian tiger mosquito spread from Asia to Europe, the Americas, Africa and Australia in only 40 years through the trade in used tires, making it a leading example of invasive-pest spread through international supply chains.
Frequently asked questions about the Asian tiger mosquito
Q: How can I distinguish the Asian tiger mosquito from other mosquito species?
A: Microscopic examination of external appearance and eggs is the most accurate method. Aedes albopictus shares the reputation of Aedes aegypti as a major disease vector.
Q: Can mosquitoes be controlled without pesticides?
A: Yes. Removing breeding sources (standing water) is the strongest and longest-lasting approach. Biological Bti is very safe for the environment and effective against larvae
