Abstract:

Objective To compare the efficacy of“bamboo strips”and“bamboo joints”baiting methods to control commensal rodents that dwell the underground sewage in Shanghai, China. Methods (1)the foraging rate was compared between“bamboo strips”and“bamboo joints”;(2)Observation was made to compare the foraging rate among the baits of Asako, fresh rice dubbed 0.005% bromadiolone bait and Bromadiolone wax blocks;(3)Trails were conducted in the underground sewage system adjacent the groceries and restaurants. Results Data from underground sewage system adjacent the groceries and restaurants indicated that the foraging rate in“bamboo joints”method (6.02%) was significantly higher than traditional“bamboo strips”method (1.39%) (χ²=8.10, P<0.05), the rodent populations dwelling in underground sewage systems showed a foraging rate of 85.07% on Asako, followed by that on fresh rice dubbed with bromadiolone bait and then bromadiolone wax block. Conclusion The“bamboo joints”method was recommended for rodent control in underground sewage system by baiting.
