Abstract

The remarkable increase in rice production was largely dependent on the development of new rice varieties. However, this has caused a new pest problem. Initial observations showed a shift in abundance of the white-backed planthopper (Sogatella furcifera) and the brown planthopper (Nilaparvata lugens) in fields planted with popular high yielding varieties of rice, hence, this study was conceptualized. Light trapping to monitor population of hoppers in CES started on March 9, 2011 and weekly thereafter. The installed JICA light trap with electronic light bulb was put on 5 hrs at night, collection of the insects caught was done the following morning and the specimens were brought to the laboratory for sorting, identification and counting. Collected hoppers during DS 2012 (Jan-June) showed a total of 1,228 brown planthoppers (BPH), 278 white-backed planthoppers (WBPH), 2,187 green leafhoppers (GLH) and 2,092 zigzag leafhoppers (ZLH). Highest collection was obtained during March, and GLH was the most abundant during the seasons. During WS 2012, July to October collections from light trap were already counted but that for the last 2 weeks of November and December was yet to be sorted and counted. Partial results for this season showed that GLH populations is still the highest and the least that of WBPH.
