Title : Toxicoligical study of Ocimum basilicum and Jasminum grandiflorum essential oils against Rhyzopertha dominica and Tribolium castaneum.

Abstract :

The study was carried out to evaluate the fumigant and repellent effect of Ocimum basilicum and Jasminum grandiflorum essential oils against Rhyzopertha dominica and Tribolium castaneum. Both tested essential oils had fumigant and repellent effect. For T. castaneum the highest concentration 0.24 mg/cm2 basil absolute had the lowest repellency with 65% while by basil oil was 82.5%, repellency. Jasmine absolute achieved the highest repellency at concentration of 0.12 mg/cm2 with 95% repellency. R. domenica was considerably more susceptible than T. castaneum in fumigant experiment. For R. dominica after 3 h basil oil had the strongest fumigant effect, with LC50 value 0.11 mg/cm3 while after 6 h basil oil had the strongest fumigant effect with LC50 value 0.07 mg/cm3. Based on LT50 Jasmine absolute seemed to be the most toxic material compared with the other materials used at the concentration of 0.4 mg/cm3, While against R. dominica calculated at four different concentration using fumigation method at the highest concentration (2.0 g/cm3) basil absolute had the strongest effect with LT50 of 2.15 h. The study also studied the chemical composition of tested essential oils and decleared that, acetic acid had the highest concentration with 15.951% for jasmine absolute and linalool is the main component in basil absolute with 46.345%, while Linalool was the main component in basil oil with 54.8%.
