    The Saharian regions have witnessed a considerable expansion in agriculture especially after the national programmes fostering agricultural investments. Our study was conducted in Ghardaia aiming to valorize the leaves of Liliaceae as a means of biological control thanks to their insecticidal effect on the aphids . 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 . The results show an average rate of mortality respectively equalling 38.77%, 20,33% and 31,88% for the garlic, Onion and the mixture of the two.
