Lethal effects of concentrated CO₂ at 40°C on adult females and eggs of Tetranychus urticae Koch were examined. No adult female survived after 6-h exposure to 60% CO₂, and almost all eggs at different ages died after 6-h treatment with 60% CO₂. No marked increase in CO₂ tolerance was observed as the egg stage progressed. These results suggest that both adult females and eggs of T. urticae can be controlled with the same CO₂ treatment at a high temperature.
