Issue Date

Abstract

One of the recent serious constraints to the rice production in Asian countries are rice planthoppers, Rice Planthoppers such as brown planthoppers (BPH) and whitebacked plant hoppers. Rice planthoppers also transmit viruses that devastate rice plants. For example, rice grassy stunt virus and rice ragged stunt virus are persistently transmitted by BPH. In the Philippines, planthopper outbreaks have damaged about 6,700 has in Iloilo and significant yield losses were reported during the wet season of 2010. This study monitored planthopper populations using light and yellow sticky traps and the associated damage in PhilRice CES, Muñoz, and Mabini, Sto. Domingo, Nueva Ecija including damage assessment in farmers’ fields. Rice planthopper population patterns in 2014-2016, and the assessment of associated damage (hopperburn) were discussed.
