To investigate the alluring effects of fruit tree insects and their populations, this experiment was carried out in Suweon district from June 13 to August 31, 1973.
The collected insects by differently colored light traps were classified as follows;
1. The 110 species of insects identified in this paper were 73 Lepidoptera, 17 Coleoptera, 11 Hemiptera, 4 Diptera, 1 Neuroptera, 3 Orthoptera, and 1 Ephemeroptera.
2. The only 15 species of all were identified as the fruit tree insects, that is, apple leaf roller, smaller tea tortrix, brown tortrix, narrower apple tortrix, peach pyralid moth, oriental tussoc moth, gypsy moth, oriental moth, tent caterpillar, two spotted leafhopper, green rice leafhopper, green leafhopper, Korean black chafer, velvety chafer and smaller velvety chafer.
3. In the comparative effects of colored lights, the most effective light source for fruit tree insects was white-60 watt and gradually decreased white-30 watt, yellow, green and red in that order.
