Abstract
Studies were carried out to determine the effect of the neem product, suneem oil, at two concentrations 10 and 100 ppm, on the second instar larvae of S. littoralis in the laboratory. Two sets of experiments were carried out, choice and no choice. Results showed that suneem oil has anti-feeding and repellency effects on the test insects and it markedly affects the longevity of larvae and pupae, impairs the normal development of larvae and has an effect on the weight of pupae, depending on the concentration used (100 or 10 ppm).Keywords
