In most cases, malaria is transmitted through the bites of female Anopheles mosquitoes. There are more than 400 different species of Anopheles mosquito; around 30 are malaria vectors of major importance. All of the important vector species bite between dusk and dawn.
When replayed at normal speed, time appears to be moving more slowly. A term for creating slow motion film is overcranking which refers to hand cranking an early camera at a faster rate than normal (i.e. faster than 24 frames per second).
In conventional movie cameras a motor drives film past a shutter at 16 frames per second for silent filming or 24 frames per second for sound and the shutter opens and closes once for each frame. A pull-down mechanism moves the film by one frame while the shutter is closed, and the film is at rest when the shutter opens for the exposure.
