Abstract
The interaction between temperature, concentration and period of exposure was studied when using methyl bromide fumigation against the adult and egg stages of Acarus siro L. and Rhizoglyphus echinopus (F.&R.). The results showed that the egg stage was more tolerant than the adult stage to methyl bromide. The gas becomes more effective against the egg and adult stages as the temperature increased from 10 to 30°C . The effective concentrations decreased in amount as a result of the increase in temperature. The rate of decrease varied form one period of exposure to another, and according to the type of mite test­ed. Data showed that R. echinopus was more susceptible to methyl bromide than A. siro .
