A study of biological efficiency of six natural substances (Cassia nigricans, Cassia occidentalis, Cleome viscosa., Mytragina inermis, Ocimum basilicum, Parkia biglobosa) organic extracts against Helicoverpa armigera (Hubner) which causes big damages to tomato has been done on laboratory conditions. The extraction of plant materials has been done using solvents with increasing polarity according to Nair’s method. The biological tests on H. armigera larvae at a dose of 100 μg / ml of nutritive diet, has been done according to a Fisher block design of 19 treatments in 4 replications. The number of dead and dwarf larvae has been counted by direct observation of the larvae using a binocular magnifying glass. Phytochemical analysis of the more active extracts of C. viscosa and P. biglobosa was done according to the described method of Ciulei. The pods of P. biglobosa contained more polar constituents and fewer apolar constituents than C. viscosa leaves. Efficacy tests showed that the methanolic extracts of C. viscosa and P. biglobosa led to the highest mortality rates of 42.65% and 21.65% respectively. The main nanism rate was at M. inermis with 68.20%. Extracts from other vegetable powders gave a lower rate of nanism which varied from 0% to 27.5%. Phytochemical analysis of active extracts revealed that C. viscosa and P. biglobosa contain some steroids, triterpenes, tannins, flavonoids, saponosides, anthocyanins and anthraquinons which could have insecticidal properties. The development of formulations based on methanolic extracts of C.viscosa and P. biglobosa would make it possible to develop bio-insecticides for an integrated pest management against H. armigera.
