Abstract
The biological and biochemical effects chloropyrifos, camphor extract and their combination were studied against the 4th instars of Spodoptera littoralis under semi-field conditions. The results indicated that the LC50 for chloropyrifos was 0.08 ppm and 13.3 x 103 ppm for the camphor extract. The estimated Co-toxicity factor was 13.2 So, there is an additive effect between camphor oil and chloropyrifos against S. littoralis.
