LED lights with specific Narrow Wavelengths ( which is possible only with LEDs ), can be beneficially used for a) Capturing unwanted moths/insects and b) Creating Rural lighting that is NOT disturbing the Pollen-Carring Insects and thereby conserving the nature's processes.
Multiple studies have found moths along with most other insects to be significantly more attracted to lamps that emit smaller wavelengths such as ultraviolet (UV) and middle of th Human Sensitivity Spectrum.
The visibility of the light to the moth, the distance between the moth and light, and the brightness of the light are also contributing factors in whether the moth will be attracted to light.
Langevelde et al. found that actinic lamps with a mean weighted wavelength of 382 nm (lamp type a) were the most attractive to moths in both abundance and species richness when compared to other lamps that emitted longer wavelengths.
Light traps have been used to monitor occurrence and abundance of pest species in order to reduce their populations (Weissling and Knight, 1994).
There might be a male-biased flight-to-light behavior of moths (Altermatt et al., 2008), The artificial lights might also cause a size-biased flight-to-light behavior, as relatively larger moth species and higher abundances of these moth species are caught in traps.The lamp types with smaller wavelengths attracted relatively more large moth species than lamp types with larger wavelengths.
LEDchip Indus P Ltd, have higher scientific understanding of the above phenomena and bring LED lamps/strips to use in Insect traps. We can consult or work with agri-scientists to evolve customised Insect Lamps if needed. The Insect lamps are made with reliable Electrical & thermal properties to increase the practical life of the Lamps and ease of use for semi-literate Farm waorkers. We can help to build Large systems for use in Resorts & Holiday Homes too.
MOTH/BIO-FRIENDLY LIGHTS -
The increase in artificial night lighting increases the urge to study effects of light pollution, to support nature management options with possible cascading effects for biodiversity and ecosystem services, e.g. in pollination etc when larger moth species decline due to light pollution. The use of spectral compositions of artificial light that have the least sensitivity for moths, namely with larger wavelengths, will effectively reduce the negative effect of light pollution on moth population dynamics and the communities that include these moths or their caterpillars.
