Özet: Fumigation with essential oils from plants is a popular, safe, and environment friendly alternative tool for pest control in stored products. To provide a range of choices and to reduce costs in a variety of contexts, more plant-derived pest management control agents from local plant species should be identified and more effective fumigant methods must be developed. This paper describes the toxic effects of the essential oils from Perilla frutescens (L.) Britt. (Lamiaceae) as a fumigant, either alone or in combination with CO2-enriched modified atmospheres, for the control of Dermestes maculatus Degeer. The essential oils showed strong fumigant activities against this pest. After six hours of fumigation with the essential oils at a concentration of 0.10 μL/L, mortalities for each life stage was 73.0% (adult), 61.2% (larva), 39.6% (pupa) and 55.4% (egg). Furthermore, the effects were enhanced when CO2 levels were increased. At an essential oil concentration of 0.08 μL/L in the treatment group with 60% CO2, mortality rate for all life stages was 100%. We propose that CO2 concentration plays a direct role during joint fumigation, as atmospheres with high CO2 levels cause the permanent opening of insect spiracles, thereby increasing the uptake of plant essential oils.
