The search for the preservation of natural resources is currently sensitizing the society about the importance of food, requiring products with minimal use of insecticides that are harmful to health, and to increase the supply of safe food to this population, we see growing use of agriculture organic and integrated pest management. In search of insects that can be used in biological control, which is an important tool in organic farming and integrated pest management, the lacewings is proving a strong controlling agent, since their larvae are predators of eggs and larvae of various insects pests of different crops. In order to evaluate the effect of neem oil, a plant extract with properties insecticides on lacewings, eggs of Diatraea saccharalis will be treated with neem oil at three different concentrations and offered as food to larvae of Ceraeochrysa claveri, thereby evaluating the effect of ingestion of neem oil in the larval stage of the spermatogenic lineage cells from the testes of third instar larva, pupa and adult of C.claveri. Through knowledge of the morphology and ultrastructure of the testes, as well as the process of spermatogenesis and the effect of ingestion of neem oil on this organ, we can inform the future viability of the combined use of neem oil and lacewings in cultures that emphasize maintenance of diversity and integrated pest management.
