| Abstract | ||||
| In lab-experiment to declare the effect of static magnetism on the essential cinnamic oil and comparing its effect with non- magnetic cinnamic essential oil and the insecticide, cymax 50% on 2nd instar larvae of the cotton leafworm, Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae). Due to the problems of chemical pesticides to all organisms and environment, natural control replaced pesticides. Results proved that magnetic cinnamic oil is the most effective material than the non- magnetic cinnamic essential oil and the insecticide cymax 50% with LC50 926.57ppm 4636.11 ppm for magnetic and non- magnetic cinnamic oil, respectively. Although LC50 for cymax 50% was 101.65 ppm, which was lowest than magnetic and non- magnetic cinnamic oil, but the highest concentration of this insecticide caused only 50% mortality for 2nd instar larvae of S. littoralis, in addition to its toxicity on plants, people and environment. So the magnetism which improved the properties of essential cinnamic oil proved its effectiveness on 2nd instar larvae of S. littoralis. | ||||
