Leaf and seed crude extracts at three concentrations (high, medium and low) of Euphorbia helioscopia L., Cannabis sativa L., and Calotropis procera (Ait.) were tested against workers and soldiers (4-5th instar) of Microtermes obesi Holmgren and Odontotermes lokanandi Chatarjee and Thakur (Blattodea: Termitidae). Results revealed that all extracts showed moderate toxic effect. 100% mortalities were found in M. obesi and O. lokanandi on day 11 and 7 respectively. Our results showed that Mortalities in both species were concentration depended. Maximum mortalities were observed in high concentration, followed by medium and low. Our results also indicated that M. obesi was more resistant than O. lokanandi.
