Abstract:
The nanoparticles have received much attention for controlling of insects pests instored grains. The efficacy of amorphous rice husk silica nanoparticles (93.14 nm) against <em>Sitophiliusoryzae </em>(L) and <em>Xanthomonasoryzae </em>were carried out. It was observed that, adult mortality of <em>S. oryzae</em> is dependent on dose and time after application. Adult mortality on 4<sup>th</sup>days showed significantly highest adult mortality (100%) of <em>S. oryzae</em> with 175 and 200 ppm and negligible weight loss. The results of antibacterial study of SNPs against <em>Xanthomonasoryzae </em>revealed that the SNPs did not have antibacterial activity in<em> vitro </em>condition. Thus, the use of rice husk silica nanoparticles as pesticide in an alternative strategy to combat <em>S. oryzae </em>insect pest which have become resistance to conventional pesticides with ecofriendly way.
