Nowadays, researches are aimed to find out new efficient alternatives
supplement for feeding mulberry silkworm by using some food additives which allow the
improvement of certain biological and reproductive parameters. The present work represents the
use of three tested plant crude extracts i.e. Chamomile, Fennel and Thyme to evaluate their
possible profitable effects on silkworm (Bombyx mori L.) productivity.
The obtained results revealed that the use of Chamomile at 3%, Fennel and Thyme at 5%
significantly increased the weight of larvae and pupae compared with the other performed
treatments.
It could be also concluded that Chamomile at a concentration of 3% and Thyme at 5% gave the
heaviest fresh cocoon weight with an increase of 18.824 and 21.487%, respectively over control. All
types of the evaluated plant crude extracts increased the egg productivity compared with the
untreated control.
