Abstract

Traps and physical barriers are commonly used for rodent control. However limited successes were achieved when these two methods were used on their own. In 1985 an innovative approach using a combination of traps and physical barriers plastic fence was successful in protecting 60.7 ha of rice surrounded by abandoned ricelands in Permatang Pauh Seberang Prai from severe rat depredation. The fence 50 cm high was erected with polyethylene material 0.03 cm thick and 61 cm width when the crop was at maximum tillering stage. The traps were made of hardwire b.r.c. 2.5 x 1.3 cm and with a dimension of 26 x 28 x 62 cm. Traps were laid at strategic locations and concentrated in places where the catches were heavy. The daily rat catches were recorded and the highest catch per night was 128. Evaluations were conducted in rat endemic areas like Cerang Rotan Kelantan Sungai Nipah/Pasir Panjang Tanjong Karang Selangor and Krian Perak. Two methods were used a the cultivated area was completely fenced in and b the fence was erected between two adjacent areas with different planting schedules. In all these locations this innovative approach successfully protected the crops from severe losses with spectacular yield increases. Since its introduction in 1985 the catch was 56 320 rats in Seberang Prai 32 041 in Cerang Rotan 44 101 in Tanjong Karang and 10 217 in Krian. Adoption of this method by farmers are willing to invest in this method. Several farmers in Seberang Prai who had suffered 75 percent yield losses grouped together of fence an area of 22.63 ha with tar-drums fence. This innovative method is particularly useful in ricelands with very high rat infestations and is also effective in situations where there is a continuous high influx of rats from the surrounding areas as high as 920 rats per night in Cerang Rotan or massive movements between ricelands with different planting schedules 6 872 rats per night in Tanjong Karang. Under such situations chemical control is ineffective in stopping the massive rat influxes.
