It is important to monitor the variation in brown planthopper (BPH) biotype when breeding resistant varieties. We have been doing this work since 1979 in Guangdong, China, including yearly testing of BPH biotype variation in Guangzhou and conducting a biotype test with BPH populations in Guangdong Province.
