During the winter and spring between 1988 and 1989, we investigated the overwintering of the cockroaches in Zhejiang in three types of environment. In the hospital ward, wintering cockroach nymphs and adults mainly inhabit nightstands. The hostel guest rooms mainly inhabit the writing desks, two-bucket tables and bedside cabinets. The residents’ kitchens mainly inhabit the top ten, the sideboards and the furniture items below and next to them . Oviduct nymphs and adults more widely distributed; black-billed cockroaches mainly to egg pods and nymphs overwintering; according to different temperatures and cockroaches activity, combined with temperature data, that the county about 2 months after the black-billed cockspetle November to March next year) overwintering period, when the temperature is more than 12 ℃, the appropriate time to eliminate overwintering cockroaches; In addition, the different environment to eliminate the difficulty of wintering cockroaches were also discussed.
