Abstract
Ozone was an effective fumigant in a biological safety cabinet against a biting gnat, Culicoides Variipennis (Coquillett), the principal vector of bluetongue virus in the United States. Mortality of female gnats exposed to 600 ± 25 ppm of ozone for 5, 7.5, 10, 12.5, 15, 30, and 60 min was 96% at 30 min and 100% at 60 min. Mortality of female gnats exposed to 140, 200, 300, 400, and 600 ppm of ozone for 1 h was 88% from 400 ppm and 100% from 600 ppm of ozone. Probit analysis showed that, at 600 ppm of ozone, the exposure time needed for 50% mortality (LD50) was 12 min; at 1 h of exposure, the ozone concentration needed for 50% mortality was 244 ppm.This publication has 0 references indexed in Scilit:
