Inhibition of Culex quinquefasciatus (Diptera: Culicidae) viability by nanosecond pulsed electric field radiation

Radiation effects of high-intensity nanosecond pulsed electric fields on the viability of Culex quinquefasciatus (Diptera: Culicidae) were determined. Statistical analyses from results show that the treatment energy density of up to 17.76 J m−3 produced the optimum result in which the number of survived mosquitoes was decreased by 20% (P < 0.05). Furthermore, the average developmental rate into adult forms of treated fourth-instart lavae was found lower compared to that of the control (P < 0.05). The present study indicates that electrical pulse characteristics, especially the pulse amplitude, might be responsible for the decrease in mosquito viability.
