Jojoba oil was prepared in the form of Nano product. Tribolium castaneum (Herbst) adults were treated with this product. Data showed that Nano Jojoba oil particulars hav a greater toxic effect at low concentration compared to its conventional form. Moreover, the lethal concentration (LC50) and lethal time (LT50) of Jojoba oil in the form of Nano were 0.23% and 2.23 days on the adults’ of T. castaneum compared with the LC50 and LT50 of traditional jojoba oil treatment which were 2.40 % and 4.04 days, respectively. High repellent effects were recorded after the treatment with Nano Jojoba oil. Also, Nano Jojoba oil was persistent as it caused in rising mortality percentages with passing time. To be proving that these forms are safe for controlling the insect, it needs more studies on experimental animals. |
