The Rice Delphacid (RD) is an invasive insect that has been a serious pest in rice in Central and South America and in the Caribbean. It was discovered in Texas in 2015 and has caused damage sporadically since that time. However, in 2025, the level of infestations and damage has increased significantly. The insect is also a vector of a disease called Rice Hojo Blanca Virus (RHBV).
