LED lights attract lesser insects than other filament lamps



A scientist research group has revealed that the domestic Light Emitting Diodes (LEDs) lights, as compared to other filament lamps, attract lesser number of disease carrying insects.

The scientist set-up LEDs, traditional incandescent lamps and compact fluorescent lamps at 18 field test sites in England, over 4,000 insects were carefully identified which led the researchers to believe that LEDs attract four times lesser insects compared to other lights, a study from University of Bristol revealed.

It was funded by Natural Environment Research Council and co-sponsored by United Kingdom (UK) lighting manufacturer, Integral LED. The field research was led by Dr Andy Wakefield under supervision of Professors Gareth Jones and Stephen Harris from the University’s School of Biological Sciences.

Approximately 80 percent of the disease carrying insects, which visited test sites, were attracted to incandescent lamps, 15 percent to compact fluorescent lights and only 2 to 3 percent of insects visited the LEDs.

Talking about the findings, Dr Wakefield said, “We were surprised by number of biting flies drawn to traditional tungsten lights. We do not know why this is but we know that some insects use thermal cues to find warm-blooded hosts in the night, so perhaps they were attracted to heat given off by the filament bulb.”

With regard to future study, the research team has now highlighted urgent need to further investigate matter which will expose heat-seeking flies. It will help massively in terms of minimizing the damage caused to human health across world by these viscous insects.

Protection from diseases such as Malaria and Zika fever is highly possible if the study is put to good use.
