A study on the sensitivity of insects to different colours of light
Abstract: The study was conducted to assess the influence of different lights in insect attraction. The experiments were carried out from April to July 2014, at night from 7 p.m. to 8 p.m. Insect light traps with Incandescent bulb, Compact fluorescent lamp, green, blue and red light bulbs of 25 watts were used for attracting the insects. From the same location four monthly sampling was carried out for each set of experiments. Seventy five species of insects belonging to nine orders (Neuroptera, Hemiptera, Diptera, Lepidoptera, Ephimeroptera, Coleoptera, Hymenoptera, Isoptera and Orthoptera) were identified and their variations were recorded. The results indicate that the light emitted by Incandescent bulb is more effective in insect attraction but the species richness was found more in blue light.
