EFFECTS OF LED LIGHTING ON THE OVIPOSITION OF FIREFLY, LUCIOLA CRUCIATA AND LUCIOLA LATERALIS

Abstract

The effects of the luminous color and luminance of LED (Light Emitting Diode) lighting on the oviposition of two firefly species, Luciola cruciata and Luciola lateralis, were studied in the laboratory. Tests were conducted using five colors of LED ray, namely white, blue, green, yellow and red. One female and three males of the firefly were put in the polystyrene case, and illuminated by LED lighting every evening. The presence of the fertilization of firefly’s egg and the number of larvae of the firefly that had hatched from the egg were examined. Females of L. cruciata did not oviposit the fertilized eggs under the yellow LED of 0.11x and the white, blue and green LED of 20 lx. Females of L. lateralis did not oviposit the fertilized eggs under the blue LED of 10lx. The present study suggested that the copulatory behavior of L. cruciata was disturbed by the illumination of the yellow LED as well as the high-pressure sodium lamp for road lighting.
