Effect of Different Coloured Light Traps on Captures and Controlling Wax Moth (Lepidoptera: Pyralidae).

Abstract

Coloured light trap Achroia grisella Fab Field experiments were conducted to determine the attractive action of different colours (red, yellow, green, blue, white and black) to adult greater ,Galleria mellonella L. and lesser, Achroia grisella Fab., (Lepidoptera: Pyralidae) and to assess the influence of trap colour on their capture moths in plastic bottles baited traps. The results demonstrated, Galleria mellonella L. and Achroia grisella Fab. can distinguish between various colours , with regard to treatment colours light traps with red light, black, blue trapped significantly higher numbers of both greater and lesser wax moths followed by green, yellow and white traps. In conclusion, a trap with red and black light colour was the best attractive equipment for the wax moths. Where, the red colour traps caught the greatest number of moths, recording, 50.0% of the total moth captured, while the, white color traps caught the fewest number of moths recording only 23.27% with average 42.977% when the traps is far from the colonies by 6 meters only, while they were 50.94 and 3.7% with average 38.58 % when the distance between the colonies and light trap were 12 meters. Future research is recommended for better understanding of the effect of trap color on the diversity and abundance of non-target insects captured.

The importance of trap type, trap colour and capture liquid for catching Dendrolimus pini and their impact on by‐catch of beneficial insects

“…Studies that have demonstrated colour preferences in moths are common. Some species prefer yellow, green and/or orange (Knight & Miliczky, 2003; Singh & Saxena, 2004; Karalius & Bûda, 2007; Roubos & Liburd, 2008), whereas others show preference for other colours (Taha et al ., 2012; Mabrouk & Mahbob, 2015) or no preference (Clare et al ., 2000; Bloem et al ., 2005; Haynes et al ., 2007).…”
