Abstract

Distribution pattern of Brumoides suturalis (Fabricius) was studied on mungbean [Vigna radiata (L.) Wilczek] during summer season. Results of various indices of dispersion revealed that distribution was random. The values of each index were comparatively higher when population was lower. However, k index of dispersion was low when the population was low. The results, therefore, indicate that the predator has tendency to aggregate in case of higher density.
