| Abstract | ||||
| The effect of neem azal-T 5% (E.C.) was tested when added to the artificial diet of the 4th and e" instar Spodptera littoralis larvae (Lepidoptera: Noctuidae). Genarally higher concentrations of 1.5, 1 and 0.7% caused 100% of accumulated mortality. The lower concentrations of 0.5, 0.3 and 0.1 % caused different percentages of accumulated mortality. Prolongation of the larval instar period, malformation effects on larval, pupal and adult stages were observed with lower concentrations. Keywords: Neem oil,Spodoptera littoralis larvae. | ||||
