Abstract: A drastic reduction (85.6%) of rodent population was achieved by a sequential application of, zinc phosphide baiting and trapping in the poultry farms. Highest success was recorded from zinc phosphide baiting (76.8 %) followed by trapping (34.52%)
Combined effect, poison bait, trapping, control, rodent.

Pest Management
To develop management strategies that attempt to reduce rodent pest problems in rural Bangladesh.
Three poultry farms, appropriately of equal size, were selected from Sreepur Upazilla in Gazipur districts. These farms were selected on the basis of high rodent infestation. Three control techniques -- acute poisoning with zinc phosphide bait and trapping with snap traps, were used in each of the three farms in a sequence. Each of the control techniques were continued for three consecutive days. Before and after the application of control techniques pre and post treatment population index were taken by setting 20 tiles for two consecutive nights. Population index was recorded in the following morning. Number of rat captured or dead rats found in farm was recorded. Efficacy of the control techniques were evaluated by population index.

Cumulative effect of trapping and poison baiting reduced about 85.6% of rodent population. Between the two control techniques highest success in rat control was recorded from zinc phosphide (76.8%) baiting followed by trapping (23.2%). It is obvious that after three days of Zinc phosphide poison baiting 23.2% rat remains in population. This remaining 23.2% rat would be hard to control by Zinc phosphide poison baiting alone. But when we changed the control techniques from poison baiting with zinc phosphide to trapping, a drastic reduction of rodent population was recorded with in next three days. This experiment showed us that by changing control techniques we can achieve higher success in rodent control in a short time.
