“…Sabry et al (2017) in ovaries and tests of adults derived from treated larvae with LC50 methoxyfenozide treatment may be affecting the plasma membrane osmotic properties, leading to dehydration and appearance of vacuoles within the oocytes ovaries while testes revealed clear reduction in cellular content and bundles of spermatocytes and spermatogonia were severely reduced in number. The tested oils succeed to cause spermatocyte depletion and this play an important role reducing gamete maturing rate and this in finding with Amaldoss (1989) spermatocytes develop into spermatids and sperm bundles are formed as a result of maturation of the spermatids, which completes spermatogenesis. Hazza et al (2009) the treatment with different concentrations of Nerium oleander caused histological changes in the ovaries including vacuolation and shrinkage of oocyte tissue, clumped of chromatin material and thickness of epithelial cells at some areas.…”

Spodoptera littoralis, cotton leafworm is a destructive pest for several economic crops. The more use of chemical pesticide the more increase of this pest resistance, that lead to discovering new natural pesticides from plant extracts and oils. The present search is targeted to suggest alternative components from natural sources that more safety to the ecosystem and had the ability to reduce insect prohibition. The experimental results exhibited highly significance effect on adult moths' vitality aspects with the pre-pupal treatments by Moringa oleifera and Ruta angustifolia at all tested concentration especially 4% concentration as shorten female moths' longevity and reduced the oviposition period. Obviously, moringa recorded the shortest oviposition period (3.00 days) while ruta oil recorded (5.33 days) compared to control (10.66 days). Significantly reduced fecundity and hatchability and increased the sterility% compared to control. The tested plant oils caused severe ovarian and testicular histological deformation and significant increase in total lipids and total carbohydrate contents also, marked DNA fragmentation in variable levels in ovaries and testes in each oil treatments at 4% concentration. The promising results of both oils on S. littoralis reproductive system can prove them be used in the integrated management programs of this pest.
