Abstract
Activity of two photosensitizer compounds were studied on different stages of Spodoptera littoralis under laboratory conditions. Copper chlorophylline and magnesium chlorophylline as a photosensitizer compounds with different concentrations were tested on S. littoralis immature stages, egg, larvae and pupae. Data showed that copper chlorophylline has a slight effect while magnesium chlorophylline has no effect on egg stage of S. littoralis. The copper chlorophylline was more toxic on 2nd and 4th instar larvae than magnesium chlorophylline under both dark and photo conditions. Therefore, both compounds were more toxic under sunlight than dark conditions when pupae were immersed at different concentrations of the both photosensitizers’ compounds. These results reflected that photosensitizers could be a potentially effective for S. littoralis control in Egypt.
