Aluminum and silica oxides nanoparticles as a new approach for control the red flour beetle Tribolium castaneum (Coleoptera : Tenebrionidae)‎ on wheat grains

Abstract EN

Two nano-particles, silica oxide (SiO2) and aluminium oxide (Al2O3) were used as stored product insect protectants compared to malathion as standard reference, by mixing with grains against the red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae).

Results obtained cleared showed that malathion had the highest adverse effect on all parameters of T.

castaneum adults.

Also, the results indicated that mortality % of T.

castaneum adults increased gradually and reduction in wheat weight loss % by increasing both concentration and exposure period.

In addition, results accentuated that the two nano-particles (SiO2 and Al2O3) significantly inhibited the number of progeny of T.

castaneum.

In addition to Al2O3 was had the most effect than SiO2 nanoparticles.

SiO2 and Al2O3 nano-particles were gave good result in this study.

It could be concluded that use SiO2 and Al2O3 nano-particles are adequate for protection stored grains as alternative method to chemical insecticides because are relatively safe for human compared to malathion.

Further research is needed in order to obtain information regarding the practical effectiveness and lack of side effects of nanoparticles in protecting stored products.
