The Dengue mosquito is aedes aegypti and the zika mosquito is aedes albopictus, usually called ‘The Asian tiger mosquito’. Aegypti feeds mornings and evenings, while albopictus feeds during the day. This is the dengue mosquito, Aedes Aegypti:
The Asian tiger mosquito particularly bites in forests during the day, so has been known as the forest day mosquito. This is Aedes Albopictus:
It takes an expert to tell the difference!
Depending upon region and biotype, activity peaks differ, but for the most part, they rest during the morning and night hours. They search for their hosts inside and outside of human dwellings, but are particularly active outside. The size of the blood meal depends upon the size of the mosquito, but it is usually around 2 μl. Their bites are not necessarily painful, but they are more noticeable than those from other kinds of mosquitoes. Tiger mosquitoes generally tend to bite a human host more than once if they are able to.
Ae. albopictus also bites other mammals besides humans, as well as birds. The females are always on the search for a host and are persistent but cautious when it comes to their blood meal and host location. Their blood meal is often broken off before enough blood has been ingested for the development of their eggs, so Asian tiger mosquitoes bite multiple hosts during their development cycle of the egg, making them particularly efficient at transmitting diseases. The mannerism of biting diverse host species enables the Asian tiger mosquito to be a potential bridge vector for certain pathogens that can jump species boundaries, for example the West Nile virus.
