Alpha-glucosidase activity is elevated in the posterior midgut after feeding in response to the blood meal, whereas activity in the anterior midgut is consistent with a nectar-processing role for this midgut region. Ecology
Distribution
Mosquitoes are cosmopolitan (world-wide): they are in every land region except Antarctica and a few islands with polar or subpolar climates. Iceland is such an island, being essentially free of mosquitoes.The absence of mosquitoes in Iceland and similar regions is probably because of quirks of their climate, which differs in some respects from mainland regions. At the start of the uninterrupted continental winter of Greenland and the northern regions of Eurasia and America, the pupa enters diapause under the ice that covers sufficiently deep water. The imago emerges only after the ice breaks in late spring. In Iceland, the weather is less predictable. In mid-winter it frequently warms up suddenly, causing the ice to break, but then to freeze again after a few days. By that time the mosquitoes will have emerged from their pupae, but the new freeze sets in before they can complete their life cycle. Any anautogenous adult mosquito would need a host to supply a blood meal before it could lay viable eggs; it would need time to mate, mature the eggs and oviposit in suitable wetlands.
The Tatars of the Altai had a similar myth, thought to be of Native North American origin, involving the fragments of the dead giant, Andalma-Muus, becoming mosquitoes and other insects. Modern era
Winsor McCays 1912 film How a Mosquito Operates was one of the earliest works of animation, which has been described as far ahead of its time in technical quality. It depicts a giant mosquito tormenting a sleeping man.The de Havilland Mosquito was a high-speed aircraft manufactured between 1940 and 1950, and used in many roles. References
