Attracting Effect of Carbon Dioxide Gas Generator on <i>Cimex lectularius</i> Linnaeus （Hemiptera: Cimicidae）

This study evaluated the effect of a carbon dioxide gas generator on bed bug attraction and revealed that the number of bed bugs captured was significantly different depending on the presence or absence of carbon dioxide. Bed bugs were significantly attracted to the carbon dioxide gas at 25°C, and were attracted to the gas generator in a temperature-dependent manner at the range of 10°C to 35°C. The carbon dioxide gas generator continuously attracts bed bugs, and the duration of activity depends on the amount of chemicals involved in the gas generation. These results indicate that higher temperature conditions enhance the reactions to carbon dioxide and the activity of bed bugs.
