Field and laboratory studies were conducted in 2014 to re-evaluate the current rice stink bug threshold in Arkansas.  Field studies evaluated sampling method and technique to develop a baseline estimate for area sampled when scouting for rice stink bugs in the field.  Subsequent field caging studies were conducted to evaluate the ability of varying densities of rice stink bug to damage rice kernels.  Supporting laboratory studies compared rice stink bug feeding preference for and ability to feed on rice panicles in different stages of reproductive growth.
