Effect of racinus communis, Brassica Nigara and Mineral oil kemesol on some biochemical aspects of larvae stage of spodoptira littoralis (boisd)‎ (lepldoptera: noctuidae)‎

الملخص EN

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.
