Abstract

This study was conducted to identify the major rice insect pests and to determine the population peaks of these pests at the PhilRice CES. Weekly monitoring was done using a light trap which was operated every Monday from 6:00 pm to 6:00 am of the following day. In four years of light trapping, the major insect pests collected were the brown planthopper (BPH), green leafhopper (GLH), rice bug, stem borer, white-backed planthopper (WBPH) and zigzag leafhopper (ZLH). GLH was the most dominant pest throughout the year followed by the yellow stem borer (YSB). It was observed that GLH abundance peak in March, August and September whereas YSB peaked in April-May during the dry season and October-November during the wet season. Although GLH was present in greater number, the occurrence of this pest was not detrimental to production since the rice tungro virus disease, its vectors was not a problem in the station during the duration of the study. YSB was considered as the key pest in late-planted rice crop but not in the regular-planted crops.
