Abstract Tuta absoluta is one of the most devastating invasive pests affecting tomato crops in Algeria. Synthetic chemical pesticides to control this leaf miner, produce harmful effects on all organisms, they increase the risk rate for public health and the environment for this the present study aims to propose alternative solutions based on the use natural products “bioinsecticide”, in order to fight against this bioaggressor. This study concerns the in vitro evaluation of the insecticidal activity of Allium sativum extract on the larvae of T. absoluta. The results of this test showed that garlic extract has remarkable larvicidal properties. Indeed, the L1 and L2 larval stages are the most sensitive towards all the concentrations, especially the concentration 30 which was the most influential. On the other hand, the requested plant requires an LD50 which exceeds 21.91% and an LD90 which exceeds 37.34% to kill 50 and 90% of the insects detected. The results obtained suggest that these natural compounds of plant origin could be successfully used in integrated pest management programs for T. absoluta.
