Abstract
Micraspis (= Verania) discolor Fab. (Coleoptera: Coccinellidae) preys on several rice pests (Samal and Misra 1985, Shepard and Rapusas 1989) and also feeds on rice pollen (Pathak and Khan 1994). M. discolor pollen feeding on rice panicles increases at flowering in all three rice seasons-boro (winter rice), aus (summer rice), and T. aman (monsoon rice)-in Bangladesh (Rahman et al 1991). A study was undertaken to determine the effects of pollen feeding by adult M. discolor at different population densities on yield components and grain yield of rice.
