Abstract

Rice, being a food staple and source of primary income of most of the Filipinos, is a very important crop in the country. Destruction to these crops will affect the life and livelihood of many individuals. One of the causes of damage to these plants are pests, like the rice black bug (RBB) or “itim na atangya”. They feed on the rice plant from seedling to maturity growth stages and causes deadhearts and whiteheads to these plants. There were reports concerning effects of RBB on certain municipalities and provinces in the Philippines. This led a need to a study that will help to predict the migration of these rice black bugs in other areas of the country, and therefore, able to prevent the spread of these pests. Thus, destruction of palay due to RBB will be minimized and will prevent losses for the farmers. Data of rainfall and temperature from 1971 to 2000 were collected from different Agromet and synoptic stations. These data were then interpolated to the map of the Philippines using GIS. Results showed that there were possible migrations of RBB in the country. However, rainfall and temperature were not the only factors affecting the migration of RBB.
