Population ecology ofSchizodactylus monstrosus (Drury) (Orthoptera) along the sand bed of Damodar river, West Bengal, India

Abstract

The paper deals with the findings on some aspect of ecology of Schizodactylus monstrosus Drury. Studies on vertical distribution showed that the highest total density was in the 0 to 20 em depth. Maximum concentration of the species was found in the first horizontal row. Monthly population structure on vertical distribution was also studied. Statistical analysis showed a significant correlation between the relative humidity and the distribution. Biomass of both the sexes and nymphal populated was estimated.
