    The Saharian regions have witnessed a considerable expansion in agriculture especially after the national programmes fostering agricultural investments.

Actually, leaves of Liliaceae are considered to be the most effective destroyer. The study showed that treating with a liquid solution based on powdre (Allium sativum L.) , or the onion powder (Allium cepa) or the mixture of both applied in a greenhouse can constitute a very interesting means of biological control .
