The invention belongs to the field of ecological risk assessment of genetically-modified crops and particularly relates to a detecting method for assessing the insect resistance of the transgenic Bt cotton by using chlaenius bioculatus motschulsky. The principle of the method is as follows: the food chain relation of chlaenius bioculatus motschulsky, cotton bollworm and cotton in the cotton field ecosystem is used, and the degree of death caused by the transgenic Bt cotton to the target organism which is the lepidopteron such as the cotton bollworm is reflected by the number of the predator clusters. The chlaenius bioculatus motschulsky is trapped by using the trap and the attractant in the perennially planting transgenic Bt cotton field and the contrast cotton field, and the number of the chlaenius bioculatus motschulsky in the perennially-planting transgenic Bt cotton field is compared with the number of the chlaenius bioculatus motschulsky in the contrast cotton field, and the comparison result shows that the number of the chlaenius bioculatus motschulsky in the perennially-planting transgenic Bt cotton field is lower than the number of the chlaenius bioculatus motschulsky in the contrast cotton field, which proves that the transgenic Bt cotton has higher insect resistance. The detecting method is accurate, is low in cost and is convenient to apply.
