Indoor bioassay of mixtures of methyl bromide and phosphine on larva of Trogoderma uariabile were carried out under following conditions: temperature: 25 ℃, and relative humidity: 75%, 3～4 instar larva, time of treatment: 5 h, proportions of the mixture of the methyl bromide and hadro-phosphine: 100:1, 100:2, 100:5 and 100:10. The results showed that the lethoal doses (LD_(50)) for the mixtures with the proportions of: 100:1, 100:2, 100:5 and 100:10 were 8.43 g,6.71 g, 6.42 g,5.89 g,3.86 g per cubic metre respectively. The effect of methyl bromide was promoted in all the four mixatures. The optimize percentage was 100:5.
