Abstract Mosquitoes are extremely harmful to humans, spreading diseases to millions of people each year, many of whom die as a result of these infections. Mosquitoes have evolved to live in low light, to identify active, moving predators to avoid, and to recognize passive objects around which to navigate. The experiments in this paper introduce a method that involves the use of LED light to flood areas with the simulated presence of actively persisting objects. In a related paper, a highly regarded mosquito laboratory at a U.S. university used a dual-color pulsing light bulb to encourage mosquitoes to prefer one place to another. Although this was shown to be a potentially life-saving technology, further study under more carefully controlled conditions is required to ascertain whether the mosquitoes’ behavior was not influenced by extraneous factors. The experiments herein capture the movement of mosquitoes away from a faintly lit, treated area towards a more well-lit one.

Radiation Cooling

From three ways of the temperature gradient, the change rate of indoor temperature and heat flux, contrast analysis the cooling effect of three cooling devices on the capillary tube, cooling ceiling and radiant floor, the conclusions could be obtained. The average of vertical temperature gradient in simulated room is equal to 1°C/m, which meets the requirements of human thermal comfort. When the temperature in simulation room falls from 30°C to 26°C, the temperature drop velocity for cooling ceiling is the fastest. The heat flux of the cooling ceiling is maximum, the second one for the capillary tube, and the least one for the radiant floor. Thus, the cooling effect of cooling ceiling is the best.
