  Abstract  
  Adult Limnophyes natalensis were collected using sticky and suction light traps during the course of a year in a Japanese food factory. Such physical control methods have been demonstrated effective for collecting adult midges. The numbers of adult L. natalensis collected with the two methods were compared by season. A total of 121 were collected over eight nights with the sticky light trap, and 194 were collected with the suction light trap, a significantly higher number. The numbers were not significantly different for winter. These results demonstrate that suction light traps are more effective for collecting adult midges in food factories.
