Modeling of the toxicity of Eucalyptus globulus Labill essential oil against red flour beetle, Tribolium castaneum Herbst

Although the application of synthetic chemicals is main method in management insect pests, their overuse has led to public concerns about environmental pollution, threats human health, and acute chronic toxicity on non-target organisms. Plant essential oils have introduced as healthy, available, effective alternatives detrimental recent years. Further, it necessary predict exact amount required pesticide save costs determine optimal conditions for achievement best outcomes. Accordingly, Eucalyptus globulus Labill oil against adults a cosmopolitan pest Tribolium castaneum Herbst (red flour beetle) along with its modeling optimization was assessed using Response Surface Methodology (RSM). The coefficients concentration time independent variables are positive, showing increase results augmentation mortality. E. showed prospective concentration-time dependent fumigant T. castaneum. A quadratic polynomial equation achieved multiple regression analysis: 7.33413 + 0.20191A 0.47313B 4.64054E-003AB 0.016349B2, which B exposure concentration. accuracy model approved through analysis variance. Results indicated that 45.50 μl/l 72.00 h-exposure would be adequate achieve 92.45% mortality According current study, high potential (RSM) suitable modelling this bio-effect.
