Description of key information

Supporting study: The lethal time (LT50, time to 50% population mortality) for Dendroctonus rufipennis (spruce beetle ) was 12.9 hours. Mortality of 83 % of beetles at 80 ppm was observed after 24 hours of exposure. The lethal time (LT50, time to 50% population mortality) for Dendroctonus simplexs (spruce beetle ) was 16.3 hours. Mortality of 77 % of beetles at 80 ppm was observed after 24 hours of exposure.

Key value for chemical safety assessment
