The rice brown planthopper (BPH) is one of the most important “outbreak” pests experienced in rice crops in many parts of SE Asia. There are several factors that might contribute to these outbreaks, including changing production practices, such as increased fertilizer use, aimed at achieving higher rice yields. However, the use of insecticides can destroy naturally occurring insect predators and parasites that keep BPH populations under control. Many research papers demonstrate that pesticides are the most important cause of BPH outbreaks.
