Effects of Ricinus communis, Brassica nigra and mineral oil Kemesol on some biochemical aspects of larvae stage of Spodoptera littoralis (Boisd) (Lepidoptera: Noctuidae).
The third instars larvae of Spodotera littoralis were topically treated with two plant oils, Ricinus communis and Brassica nigra and one mineral oil, Kemesol 95% dissolved in petroleum ether and acetone at concentrations of 0.8, 1.6, 2.0, 3.0 & 4 %. The results revealed that the mean values of the total haemolymph and fat body protein was reduced in larvae treated with B. nigra and Kemesol 95%. A significant decrease was observed in haemolymph and fat body protein contents in larvae treated with all tested compound, the remarked decrease was noticed at the highest dose (4%) in both two solvents.
