Abstract
Callosobruchus maculatus (Fabricius, 1775) (Coleoptera: Chrysomelidae) is the main post-harvest pest of Vigna unguiculata. The objective was to evaluate the fumigant activity of Ocimum basilicum essential oil and its major components linalool and estragole, on C. maculatus, through the evaluation of toxicity, oviposition inhibition, instantaneous rate of population growth (ri) and insect development. The experimental units were composed of 0.8 L flasks treated with concentrations of 1.2 to 3.6 μL L-1 of O. basilicum essential oil, linalool, and estragole, applied on filter paper discs with a microsyringe. Each treatment had four replicates with adult insects exposed for 48 h. C. maculatus development rate was evaluated through a daily count o emerged adults. Oviposition was evaluated at the concentrations (LC50, LC25, LC10, and LC1). The LC50 and LC95 of O. basilicum essencial oil, linalool, and estragole were 1.79 and 4.36 μL L-1 of air, 1.68 and 3.35 μL L-1 of air, and 1.51 and 2.87 μL L-1 air, respectively. The increase in essential oil concentrations reduced the ri, rate of development, oviposition and number of eggs of C. maculatus, thus having potential to control this pest.
