Abstract
The attraction of three chironomid species, Glyptotendipes paripes Edwards, Chironomus crassicaudatus Malloch, and Polypedilum halterale (Coquillett), to incandescent light of different colors and wattages was studied. Field-captured adults were released from the center of a dark room (9 by 9 m) equipped with a New Jersey light trap in each corner. The effects of color were determined by using 100-W lamps of red, orange, yellow, green, blue, and white. The effects of light intensity were studied by using 100, 60, 40, and 25-W white lamps. Measurements of light intensity of each lamp were taken. Among the colors tested in two separate combinations, white light attracted the maximum numbers of adults and red light the least. The three species exhibited a similar behavior. Among white light of different intensities, the maximum attraction of G. paripes occurred toward the highest intensity and the minimum toward the lowest intensity. The midge species responded more to the quantity (power or intensity) than to the quality (color or wavelength) of light
