Nano bio pesticide for controlling cotton leafworm Spodoptera littoralis (Lepidoptera: Noctuidae)‎

Abstract EN

Nanoparticle compounds such as Moringa oleifera Lam.

leaf powder, boiled white and brown eggshells powder for chickens and kapritia spring water form Siwa Oasis in Egypt, these natural materials were evaluated for first time under laboratory conditions against the 4th instar larvae of cotton leafworm Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae).

The results investigated that new nanoparticles of all eggshells and M.

oleifera powder and kapritia water affected on biological aspects of target pest such as, larval mortality were recorded that,10, 8, 6 and 4% for M.

oleifera, kapritia water, brown and white eggshells, respectively, compared with control 1%, the intermediated shapes were recorded during this studied.

Also adults moths emergency percentage of S.littoralis are decreased to 89 , 82, 73 and 65 % after treatment with white eggshells, brown eggshells , M.

oleifera leaf powders and kapritia Siwa water, respectively, compared with control 93%.

Subsequently, adults malformed increased after all treatments; fecundity (Eggs/ female), fertility and also were affected.

These compounds considered as nanoparticle, these innovation technologies to enhance our country developmental strategies in order to achieved sustainable agriculture and integrated crop management by alternative insecticide, environmental protection form pollutant, increase natural enemies for insect and food safety for better human healthy for a new generation.
