The Philippines is the number one rice exporter in the world and the annual losses from rodents range from 5-10%. Rattus tanezumi and Rattus argentiventer are the major rice field rats in the Philippines. There was no difference in landscape variables between management types (Table 1). R.S. This article discusses the impact of field rodents on crops and as human pathogens, especially in Developing Countries. Hence, the present study was undertaken to evaluate the field efficacy of various integrated rodent management modules against rodent pests in irrigated rice Management of the Rice-field Rat in Indonesia Table 3. Integrated Rodent Management in rice field Recognize the problem Rice field rats are becoming an important pest due to the damage they cause to rice plants and because they act as a vector for Leptospirosis disease. The purpose was to consider the trend of the damage and to analyze rodent populations found in the fields all year round. Field Museum of Natural History, Chicago, Illinois, USA. The first research approach is ecologically-based management of rodent pests in rice fields of Southeast Asia. Whatever the kind of rodent, we need to be concerned as they can cause Rodent Management Programme.

Existing rodent pressures either from surrounding fields or within a newly planted field is the first source of conflict between rodents, your crop and equipment. Examples on field rodent management from Southeast Asia and South Pacific are presented in this paper. Ecologically Based Rodent Management (EBRM) seeks sustainable solutions for the mitigation of rodent damage through assessments of rodent population dynamics, agroecosystems, and sociocultural contexts. Population forecasting for management Since the most serious damage occurs in autumn, and rodent control often begins in early spring, there is a strong need to be able to forecast the popUlation of hamsters in autumn. Heath: In addition to baiting and trapping as the standards for rodent management service, facility staff efforts to maintain sanitation, eliminate harborage, and maintain the building for exclusion are important.

Northern Australia is the The best approach for rodent control takes an integrated pest management (IPM) approach that includes sanitation, exclusion, lethal control, and occupant education. This book covers experimental design of field experiments on rodents, introduces ecologically-based rodent management, and describes field methodologies (including breeding biology, population dynamics, monitoring of movements, diseases studies, damage assessment) and sociological tools. Damage was monitoring the situation of rice caused by the destruction of rodents in Thailand. Live trap Typical field symptoms include seed eaten at planting, plant sheaths or tillers cut at 45 degrees near the base, or missing grains or panicles.
