Hot color LEDs are less attractive to mosquitoes than cold colored lights

Hot colored LEDs will attract less insects than cold colors and if you want to be bitten by the most, stand by the filament lamp. That is the conclusion of American scientists about the ability to attract mosquitoes to different lamps, providing a better way to prevent mosquito bites, thereby preventing dangerous diseases caused by this insect. Infectious.

According to ecologist Michael Justice of the University of North Carolina, the study's author this time: "This is the first study to directly compare the outdoor usability of different types of light bulbs. Seeing the popularity of LEDs can reduce the impact of light pollution on insects and inadvertently, it generates a way to dispel mosquitoes for humans. "

To determine this, Justice and the team set up a funnel-shaped trap inside which fitted a light bulb. Every day they change 1 of 6 different light bulbs inside and in the morning the number will come as well as the insects that fall into it. In order to ensure that the moonlight did not affect the results of the study, the group recorded the full moon cycle in three consecutive weeks and used every means to ensure that each type of light bulb received the illumination of moonlight as the same. together.

Different types of lamps have different ability to attract mosquitoes.

Besides, they also ensure the weather conditions do not interfere with the research results: "If the weather in the process of catching insects with light bulbs is unusual, the research results will no longer be accurate. Fortunately, we can minimize these effects by studying the weather forecast and cleverly planning which lights to use at night. "

The experiment was conducted during the summer and eventually, they caught 8,887 insects with this light trap. Of course, each light bulb will catch a number of different insects. In general, incandescent bulbs will attract the largest number of insects , followed by compact fluorescent lamps, halogen lamps, cold color LEDs, insect-catching lights and eventually hot-colored LEDs.

Justice said he was quite surprised that the insecticidal lamps had an ineffective performance and it depended on the color of lamps used. At the same time, it is also the only lamp that gives a great effect of attractiveness among different types of insects, typically between the beetle (chafer, .) compared to the beetle.

Although this is a study that has not been reviewed or published in major journals, it has been reported at the recent Scientific Advancement Conference organized by the American Science Association and received positive feedback. extreme from the experts, contributing to providing more problems to prevent and kill insects harmful to each person.
