Results The Lianjie cockroach-killing bait had strong attractive capacity on the nymph and adult of B.germanila. B.germanila around the baits would be attracted within several seconds to one minute after application. Most of cockroaches fed on acephate bait were knocked down after 18-20 h and all died after 30 h. For the cockroaches fed on boric acid bait, the knocked-down peak occurred after treatment for 22-24 h and the mortality reached 100% after treatment for 36-38 h. In the simulated spot tests, it was found that the B.germanila fed on the Lianjie cockroach-killing baits died within 48 h. After the Lianjie cockroach-killing baits were applied in the restaurant, no cockroach was found after application for 3 d. Conclusion The Lianjie cockroach-killing bait had good control effects on the B.germanila, and it is worth to be popularized after commercial production.
