Concentrations used by treatment to evaluate the effect on oviposition of Callosobruchus maculatus (Coleoptera: Chrysomelidae) and number of eggs (average ± SD1) of C. maculatus in cowpea beans treated with Vanillosmopsis arborea essential oil and its α-bisabolol component as a function of LC50, LC25, LC10, and LC1.
| Treatment | Vanillosmopsis arborea essential oil | α-Bisabolol | ||
|---|---|---|---|---|
| Concentration (μL L−1 of air) | Number of eggs ± SD1 | Concentration (μL L−1 of air) | Number of eggs ± SD1 | |
| LC50 | 5.2318 | 10.75 ± 1.70 aE | 2.4705 | 5.00 ± 0.81 bE |
| LC25 | 3.6051 | 35.75 ± 2.21 aD | 1.4659 | 14.00 ± 1.41 bD |
| LC10 | 2.5784 | 48.25 ± 2.21 aC | 0.9164 | 23.75 ± 1.5 bC |
| LC1 | 1.4481 | 75.00 ± 1.82 aB | 0.4083 | 63.00 ± 1.82 bB |
| Hexane | — | 79.50 ± 1.29 aA | — | 79.25 ± 0.95 aA |
| Control | — | 81.00 ± 1.82 aA | — | 80.25 ± 1.25 aA |
Means followed by the same lowercase letter per line or upper case per column do not differ by a 5% probability by the Tukey test; LC = Lethal concentration (μL L−1 of air); 1SD = standard deviation.
