Screening of Plant Essential oils for Controlling Lasioderma serricorne and Their Effects on the Main Chemical Components of Cigar Tobacco
摘要
Abstract
In order to screen out the plant essential oils with good fumigation and repellent effects on Lasioderma serricorne,and to evaluate whether they have any adverse effects on the chemical composition of cigar tobacco leaves,four kinds of essential oils with relatively high fumigation activity against adult L.serricorne were first screened from seven kinds of plant essential oils in this study.The fumigation toxicity and repellent rate of the two essential oils against adult L.serricorne were then determined.The cigar tobacco leaves were fumigated with the two essential oils with the best fumigation effect,and their effects on the six main chemical components of cigar tobacco leaves were detected.The results showed that the corrected mortality rates of larvae L.serricorne after 48 hours of exposure to four out of the seven essential oils(tea tree essential oil,citrus essential oil,Litsea cubeba essential oil,and oregano essential oil)were all above 70%,and could be used for the subsequent experiments.All the four essential oils exhibited good fumigation and repellent activities against adult L.serricorne.Among them,tea tree oil exhibited the strongest fumigation toxicity,with a 24 h median lethal concentration(LC50)of 15.410 μL·L-1 and a 48 h LC50 of 11.079 μL·L-1.The weakest fumigation toxicity at 24 h was observed with oregano essential oil(LC50=21.012 μL·L-1),while the weakest fumigation toxicity at 48 h was observed with Litsea cubeba essential oil(LC50=15.109 μ L·L-1).The oregano essential oil demonstrated the strongest repellent activity,achieving a repellency rate of 93.33%after 1 h and 46.67%after 8 h.This was followed by citrus essential oil,which achieved a repellency rate of 76.67%after 1 h and 53.33%after 8 h.Based on the comprehensive consideration,tea tree essential oil and citrus essential oil were selected for the tobacco quality assessment experiment.The results showed that the fumigation with tea tree essential oil and citrus essential oil had no significant effect on the contents of reducing sugar,total sugar,total alkaloid,total nitrogen,potassium and chlorine in cigar tobacco leaves.In summary,tea tree essential oil and citrus essential oil both had favorable fumigation insecticidal activity and tobacco leaf safety,demonstrating potential for application in the prevention and control of L.serricorne during cigar tobacco leaf storage.关键词
