Fumigant toxicity of essential oils from Citrus reticulata Blanco fruit peels against Tribolium castaneum Herbst
(Coleoptera: Tenebrionidae)
Certain compounds of plants such as essential oils, with insecticidal properties have been considered as alternatives to chemical pesticides for pest control. This study reports the fumigant toxicity of <em>Citrus reticulata </em>Blanco (Rutaceae) peel essential oils against stored-product insect pest, red flour beetle, <em>Tribolium castaneum</em> Herbst (Tenebrionidae) adults<em>.</em> Experiment was carried out at 27 ± 1 <sup>°</sup>C and 60 ± 5 % relative humidity in darkness. Experimental concentrations were 15, 22, 31, 45, and 63 μl/l air tested on adult (1-7 days old) insects after 24 and 48 h of exposure. Results indicated that essential oils from C. <em>reticulata</em> had fumigant tocxicity effects against this stored pest. LC50 values were 38.2 and 35.6 μl/l air at 24 and 48 h after exposure of <em>T. castaneum</em> adults respectively. The essential oils of <em>Citrus reticulata </em>fruit peels at the highest dose of 63 μl/l air caused 76.6 % and 79 % mortality of insects after 24 and 48 hours of exposure, respectively. Mortality of <em>T. castaneum </em>increased with both increase in concentration of <em>C. reticulata </em>oils as well as exposure time of treated insects. These results suggest the potencial of <em>C. reticulata </em>oil as a control agent against <em>T. castaneum</em>.
