Abstract

The Rice blackbug, Scotinophora coarctata (Fabricius, 1798) is one of the major rice pests causing high yield loss in terms of rice production in the Philippines. Resistant varieties developed to reduce yield has never been successful as there are populations of the pest that are able to survive and utilize the different rice types. It was argued that population differentiation occurs in deployed rice varieties thus this study was conducted. Landmark - based and outline morphometric analysis and correlation analysis based on distances (CORIANDIS) were used to compare the shape and sizes of the head, pronotum, abdominal segment, genital plate and scutellum of rice black bug individuals associated with rice host varieties. Results of the analysis showed that RBB populations differ in the shapes and sizes of the scutellum indicating a significant rice host associated shape differences. It can be concluded from this study that rice types or genotypes affect population structures of the pest.
