Abstract:

A recently developed yield loss simulation model for rice pests was tested under the different production situations (PSs) of South Asia and Southeast (Willocquet et al 1998, 1999). The work reported here aimed at testing this model under a reference PS (PS2) used in experiments done at different sites, and under a second PS (PS4) not yet addressed in previous work, where the crop experiences high water stress. Deadhearts and whiteheads caused by stem borers and weeds were considered as common rice pests that can cause yield losses in tropical Asia (Savary et al 1998).
