Attractiveness of a high-pressure sodium lamp to photo-positive flying insects in comparison with a mercury lamp was investigated in a factory yard. The ultra-violet emission from the high-pressure sodium lamp was about 1/60 to as much as that of the mercury lamp. The lamps were mounted on the tips of 4 pillars of 5.7m height and located more than 28m away from each other. The difference of attractiveness was measured by the number of captured insects on the sticky traps set closely near and 5m below to the lamps. The high-pressure sodium lamp was about 50% less attractive than the mercury lamp. The number of insects around the entrances of the factory buildings was also determined by sticky traps under illumination of the mercury or high-pressure sodium lamps. The trap catches of insects decreased when illumination was changed from the mercury to high-pressure sodium lamp. No competition in attractiveness to insects among the lamps was observed even when the two kinds of lamps were used at the same time. The effect of the change of the lamps was different among insect groups. The trap catches of Lepidoptera, Hymenoptera, Hemiptera and Coleoptera insects more remarkably decreased than those of Diptera insects when mercury lamps were replaced to high-pressure sodium ones.
