Attraction of the Melon Thrips, Thrips palmi Karny (Thysanoptera: Thripidae), to Traps Combined with a Colored Sticky Board and an LED (Light Emitting Diode).

The attraction of the melon thrips, Thrips palmi Karny, to two types of traps combined with a colored sticky board and an LED array was investigated in 2010 in an eggplant greenhouse. The colors of the sticky boards were blue, yellow and white, and the peak wavelengths of the LED arrays were 470 nm (blue) and 375 nm (ultraviolet). The "direct type" of traps was designed to directly illuminate the plants with an LED array and set along the upper edge of the board whose sticky surface was directed to the plants. In the" reflective type" of traps, the LED array was set close to the plants and directed toward the sticky boards. As a result, the number of adult thrips caught was significantly larger in the reflective type of trap with combination of the blue sticky board and the blue LED. [ABSTRACT FROM AUTHOR]
