The other characteristics do not differentiate between sexes. 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. Comparison with approved pictures is the best way to determine the species with certainty. (1995), Feltner, H. and Ferrao, P.

Unidirectional cytoplasmic incompatibility, Bidirectional cytoplasmic incompatibility. In 1894, a British-Australian entomologist, Frederick A. Askew Skuse, was the first to scientifically describe the Asian tiger mosquito, which he named Culex albopictus (lat.
Depending upon region and biotype, activity peaks differ, but for the most part, they rest during the morning and night hours. This allows control of the spread of diseases that many species carry by suppressing reproduction of the individuals with the harmful disease, but without the Wolbachia infection.

Also, bidirectional cytoplasmic incompatibility occurs when an infected male carrying one strain of Wolbachia reproduces with an infected female carrying a different strain of Wolbachia.
Ae. Flowing water will not be a breeding spot, and water that contains minnows is not usually a problem, because the fish eat the mosquito larvae.
The relationship between Wolbachia and its host might not have always been mutualistic, as Drosophila populations once experienced decreased fecundity in infected females, suggesting that Wolbachia evolved over time so that infected individuals would actually reproduce much more.
By contrast, the male member of the species primarily feeds on nectar and does not bite. Banjo Paterson wrote about the Hexham Grey in a poem about a horse race. Up to 90% of the gathered spiders from rubber plantations and a cemetery fed upon Asian tiger mosquitoes.
