Laboratory tests were conducted to determine the toxicity of phosphine and methyl bromide to the eggs and postembryonic stages of Trogoderma variabile Ballion at various temperatures and exposure periods. Results indicated that both fumigants were more effective as the exposure time and/or the temperature increases. Young eggs were more tolerant to phosphine than the other stages. The most tolerant postembryonic stage to phosphine was the mature larva. There was very little difference in the susceptibility of eggs, mature larvae, or pupae to methyl bromide.
