<br/><br/> The present study was carried out to evaluate the probable effect of datura, Datura stramonium and halfa, Legeum spatum extracts on some productivity characters of the mulberry silkworm, Bombyx mori L. Summarized data are as follows:  Applying ethanolic and chloroform extracts of D. stramonium during 4th instar resulted in producing heavier fresh cocoon weigh1 (0.910 and 0.941g), respectively. The same trend was also recorded for the cocoons resulted from 5th instar larvae treated with chloroform extracts of the two plants. Other extracts were nearly similar to the control (0.850g).  Feeding 5th instar larvae on chloroform extracts of datura and halfa, as well as chlorpyrifos methyl increased significantly pupal weight.
