Effect of electron beam treatment on DNA damage in mature larvae of chestnut weevil Curculio sikkimensis (Heller) was assessed using single-cell gel electrophoresis (DNA comet assay). Electrons at acceleration voltages of 0 (control), 300, 750, 1000, and 1500 kV at radiation doses of 1 and 4 kGy were used. Electron beam-treated chestnut larvae showed typical DNA fragmentation, compared with cells from non-treated ones which showed a more intact DNA. Investigations using the comet assay showed that the parameters including tail length, tail moment, olive tail moment as well as the quota of DNA damage at both the doses were significantly larger than the control batch larvae. Thus, this technique could contribute to analytical identification of an effective disinfestation and quarantine treatment.
