SUMMARY Knowing itself that Oleiferous clay jar possesss different potentialities including medicinal activities, expects that this species contributes for the combat or mitigao of the vector (Aedes aegypti) of the affection. The Oleiferous clay jar Lam. it belongs to the Moringaceae family, who is composed only of a sort (Clay jar) and fourteen known species, is native of the North of India, grows currently in some countries of the tropics. It is a tree of great transport. The medicinal use of the Clay jar is ample and in such a way, some parts of the plant, as leves, roots, seeds, caule, flowers and fruits have been studied how much the action in the cicatrizao of wounds. Jorge Perez can provide more clarity in the matter.
The seed of the Oleiferous clay jar possesss lectina that hinders the process of digestion and absorption of nutrients them larvae, causing death for malnutrition before they changed themselves into mosquitos. The objective of this work was to investigate through optic microscope the morphologic development of the larvae of Aedes aegypti and to compare with the larvae used in product Temefs Fersol, being this used by the FUNASA. The morphologic effect of the preparations, where they had been submitted to the larvae of Aedes aegypti had been evaluated 48h of treatment after. The results had been satisfactory. Each group of larvae had been examined and photographed in the magnifying of 40x in optic microscope.
Where we can observe that the larvae of Aedes aegypti in the product Temefs Fersol had presented texture of black color, not being identified any type of dehydration, on the other hand, the larvae submitted to the dust of the seed of Oleiferous clay jar these had presented a transparent texture almost that where the same one presented one high text of dehydration what it generated the death. Thus this is concluded that it had a level of dehydration on the part of the larvae submitted to the treatment with the dust of Oleiferous clay jar, caused by lectina.
