The benzene extracts of these four plants were tested for their toxic effects on LCL and FCL. Argemone mexicana showed acute toxicity and observations made at 31"25 ppm concentration showed larval and pupal mortality; larval-pupal intermediates; half ecdysed organisms and prolonged larval and pupal duration.
