In order of incidence of plants with pests, it showed that: whitefly (99.17%) cotton aphids (98.33%) cotton thrips (74.58%) mirid bugs (43.10%) cotton spider mites (20.95%). Compared with other pests, whiteflies had a highest inci- dence in the flower and boll stage of Bt cotton in Henan Province, and mirid bugs and cotton spider mites mainly occurred in the flower and boll stage in Hebei Province. Conversely, cotton aphids and cotton thrips showed the highest incidence at the bud stage in Hebei and Shandong Provinces, respectively. The results indicated that non-target pests showed significantly different occurrence and damage rates in various developmental stages of Bt cotton in different regions.
