Section 4 • Integrated Insect and Rodent Pests Management<br />

4. Synthesize and summarize output <strong>of</strong> small groups into one big group output. Draw up<br />

conclusions and recommendations from this exercise.<br />

5. Facilitate farmers to install cage traps and scaring materials when early infestation signs <strong>of</strong> rats<br />

are observed in learning field by improving procedures given below:<br />

Option 1 (Using Cage Traps)<br />

5 Acquire or fabricate and install at least five cage traps with appropriate baits in strategic<br />

places (e.g., runways and burrows) <strong>of</strong> learning field be<strong>for</strong>e nighttime;<br />

5 Inspect and gather cage traps with rat catches in the succeeding morning;<br />

5 Record and dispose rat catches promptly;<br />

5 Reinstall cage traps in the same area be<strong>for</strong>e nighttime;<br />

5 Gather and reinstall cage traps without rat catch near reinstalled cage traps with previous<br />

rat catches. If possible, estimate percent rat damage;<br />

5 Repeat process daily until necessary; and<br />

5 Take note <strong>of</strong> all relevant observations and experiences during this activity.<br />

Option 2 (Using Scaring Materials)<br />

5 Install scaring materials (e.g., used cassette tapes, used plastic bags or cellophane, etc.) at a<br />

distance <strong>of</strong> one-meter in rows within plots;<br />

5 Inspect and record presence <strong>of</strong> runways, burrows, footprints, and feces in the succeeding<br />

morning;<br />

5 Inspect and also record signs <strong>of</strong> rat damages on plants and plant parts in the succeeding<br />

morning. If possible, estimate percent rat damage;<br />

5 Repeat process daily until necessary;<br />

5 If different scaring materials were used, determine best scaring materials; and<br />

5 Take note <strong>of</strong> all relevant observations and experiences during this activity.<br />

some suggested questions <strong>for</strong> processing discussion<br />

❏ Did you observe farmers using cage traps against rats in their fields? Did you observe farmers<br />

using scaring materials against rats in their fields?<br />

❏ What traps and scaring materials against rats were commonly used by farmers?<br />

❏ Did you observe any differences in effectiveness among different traps and scaring materials<br />

used against rats? When is it practical to use cage traps against rats? When are scaring materials<br />

more practical to use against rats?<br />
