Response of Insects to the Light and Coloured Sticky Traps

Research regarding response of insects to the light and coloured sticky traps have been done in fruit and red chili garden in Sumedang and Lembang area.The coloured sticky traps consisted of transparent, grey, brown, black, red, yellow, green, blue, and white were placed at fruit and red chili garden, meanwhile light traps were placed in red chili garden.Research was designed at Randomized block design, 9 treatments and 3 replications.Size of coloured sticky trapsare 30 cm X 30 cm.Observations were made on the number and kind of insects trapped on the seventh day, especially for fruit fly (Bactrocera spp.); which became the main pest of fruits and red chili; and thrips.The results showed that the most favoured colour for fruit flies is white, either it was installed on fruits, or on red chili.Yellow is the most attractive colour for insects generally, especially thrips in the red chili garden.Light and coloured sticky traps are able to trap a variety of insect pests, including useful insects such as pollinating insects and predators, but the numbers are quite small (under 1%) when compared with the number of insect pests trapped.
