• A research project was carried out aimed at to study the toxic effects of Palpoluck Polygonum hydropipper L. and Bhang Cannabis sativa L. crude extracts against two species of termites i.e. Heterotermes indicola (Wasmann) and Coptotermes heimi (Wasmann) at Nuclear institute for Food and Agriculture (NIFA) Peshawar, Pakistan in April 2002. Results revealed that after ten days of feeding maximum percent mortality in case of Polygonum hydropipper L. leaf and flower extracts was 28.0, 52.0, 28 and 74.7 for H. indicola and Coptotermes heimi respectively, while in control only 10.7 and 12.0% mortality were recorded. Similarly, for the same species of termites the percent mortality in Cannabis sativa L. extracts was 54.7, 64.0, 58.7 and 70.7 for leaf and seed extracts respectively, while in control only 12.0 and 10.7% mortality were observed. In each extract mortality was significantly different from that of control. Toxic effects of both extracts (leaf and flower) were more profound against Coptotermes heimi than Heterotermes indicola during these ten days of feeding. Also the seed extracts caused more mortality than the leaves for both species, suggesting the availability of high contents of toxic materials in seed.
