B. gerrnanila around the baits would be attracted within several seconds to one minute after application. Most of cockroaches fed on aeephate 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. gerrnanila, and it is worth to be popularized after commercial production.
