Effect of Nano particles against cigarette beetle (Lasioderma serricorne Fabricius) in cured turmeric rhizomes (Curcuma longa Linnaeus)

Abstract

An experiment was conducted to study the effect of different nano particles, viz, Nano silica @ 0.5g kg-1, 0.25g kg-1, 0.175g kg-1 of cured turmeric rhizomes, Nano alumina @ 0.5g kg-1, 0.25g kg-1,0.175g kg-1 of cured turmeric rhizomes, Nano clay @ 0.5g kg-1, 0.25g kg-1, 0.175g kg-1 of cured turmeric rhizomes and Diatomaceous earth @ 5g kg-1 of cured turmeric rhizomes (check) along with control. All the treatments were replicated thrice. Among the three nanocides, nano silica applied at 0.5 and 0.25 g kg-1 dosages showed the superior performance of the over other treatments at one day after treatment followed by nano silica at 0.175 g kg-1 which caused higher mortality, reduced oviposition and adult emergence of L. serricorne and has a great promise in cigarette beetle pest management.
