Abstract
A trial study was managed to estimate the efficacy of neem oil and cinnamic oil on cowpea aphid, Aphis craccivora Koch (Hemiptera: Aphididae) which infest a wide host range of plants caused serious damage. Due to the problems of chemical pesticides to organisms and environment, natural control replaced pesticides. The data obtained in this study showed that neem oil was more effective in controlling A. craccivora where LC50 was 125.26 ppm comparing with cinnamic oil which LC50 recorded 378.68 ppm. GC/ MS analysis of Neem oil showed the presence of saturated and unsaturated fatty acids by 99.34%, where it was found to contained eight different fatty acids. The linoleic acid represents the highly proportion with 34.69%.
