Atmospheric Cold Plasma (ACP) Treatment for Efficient Disinfestation of the Cowpea Weevil, <i>Callosobruchus maculatus</i>

Highlights The exposure of C. maculatus to reactive gas species (RGS) from atmospheric cold plasma treatment (ACP) resulted in significant mortality at all life stages tested. Three-minute ACP treatments voltages 70 kV have the best insecticidal effect. greatest impact was during egg and young larval . Abstract. capability mechanism high-voltage were studied using a dielectric barrier discharge reactor against Callosobruchus maculatus, insect pest stored grain degradation. rate &amp;gt; 90.0% for can be achieved with longer time 3 minutes higher voltage kV. However, this condition, paired post-treatment retention 4 days, is required kill 95% adult insects. use has considerable on range stages. Sufficient toxicity by process management modified pressure working 65% oxygen, 30% carbon dioxide, 5% nitrogen address lifecycle phases that are vectors pathogens, which increase mycotoxin contamination degrade quality. Introducing as an alternative chemical fumigation may provide safer integrated management.
