Effet insecticide des extraits aqueux d’Euphorbia Guyoniana (Euphorbiaceae) récoltée dans Oued Sebseb (Sahara algérien) sur le Tribolium Castaneum

Stored products are among the most important foods in human nutrition. However; these products are under the pressure of many harmful organisms. One of these pests is Tribolium confusum Jacquelin du Val. (Coleoptera: Tenebrionidae). In this study, effects of two essential oils (Mentha rotundifolia and Satureja calamintha) and an enthomopathogenenic fungi on Tribolium confusum has been tried under the laboratory conditions, contact and repellent effects of essential oils and contact effect of dry plant extract were determined. As a result, essential oil, 3, 5, 10, 15 and 20 μl / ml doses of Mentha rotundifolia showed 100% effect after 24 hours, while Satureja calamintha reached 100% effect after 96 hours. 15 μl / ml dose of M. rotundifolia and 20 μl / ml dose of S. calamintha reached 100% detrimental effect after two hours. Powder doses of 0.6, 0.8 and 1.0 g of these plants, which were applied, caused the death of all the male and female individuals after 24 hours. In addition, the effects of 1x10 7 conidia / mL dose of the entomopathogenic fungus Beauveria bassiana after 24, 48 and 72 hours were 87.5%, 97.5% and 100%, respectively. It was seen that both essential oils and B. bassiana were successfully in suppressing the depot pest Tribolium confusum.

The aim of the present work is to study the chemical composition, to estimate the phenolic compounds content and to evaluate the potential allelopathic effects of the Haloxylon scoparium Pomel. Phytochemical tests revealed that Haloxylon scoparium contains tannins, saponins, coumarins, alkaloids, flavonoids and steroids. Furthermore, it contains high levels of total phenolic (588.33 mg GAE 100 g-1) and flavonoids (95.45 mg QE 100 g-1) contents. Moreover, LC-MS-MS analysis allowed us to determine their chemical composition. The results of this characterization confirm the presence of vanillin, naringenin, folic acid, maleic acid, benzoic acid, myricetin, qwuercetin, beta-carotene, butylhydroxyanisole (BHA), butylated hydroxytoluene (BHT), rutin, cafeic acid, hydroxy-4-coumarine, ascorbic acid, and gallic acid. The allelopathic effect was studied on seed germination and seedling growth of four weed species. The bioassays were performed using different concentrations (1 %, 2.5 %, 5 % and 10 %) against a negative control. The seed germination, shoot and root length of weed species were completely inhibited at the highest concentrations (10 %, 5 %). However, the lower concentrations exhibited lesser inhibition percentages on the germination and the seedling growth. The phytochemical results and the significant allelopathic effects of the plant extract suggest that this species may offer new substances for the biocontrol of weeds.
