The College of Education for Pure Sciences discussed the master's thesis entitled "The use of some nanomaterials as insecticides against the sawn grain beetle." The study presented by the student Fatima Ibrahim Khalaf and under the supervision of Prof. Mostafa, to evaluate the effect of some metallic nanoparticles (gold nanoparticles, iron oxide nanoparticles and titanium dioxide nanoparticles) on the life of the sawn beetle because of this insect's great impact on rice seeds. The possibility of making use of the materials as future insecticides due to their low cost, ease of use and friendliness with the environment compared to chemical pesticides. The researcher recommended the use of nanomaterials as protective materials for rice seeds used for cultivation against the beetle infestation because of their effective effects on its life and on limiting its reproduction and spread, and making clips Histology of the insect to know the effect of the nanomaterials on the various body systems and the mechanics of their work.
