Mortality of Callosobruchus maculatus (Coleoptera: Chrysomelidae) by Vanillosmopsis arborea essential oil and its α-bisabolol component at concentrations of 1.2, 1.6, 2.0, 2.4, 5.6, 8.4, and 11.2 μL L−1 of air corrected by Abbott’s formula41.

| 11.2 | 18.00 a | 76.3 | 19.00 a | 77.6 |
Means followed by the same letter per line do not differ to a 5% probability by the Tukey test; E (%) = Efficiency of mortality corrected by Abbott’s formula41.
