Fumigant Activity of the Psidium guajava Var. Pomifera (Myrtaceae) Essential Oil in Drosophila melanogaster by Means of Oxidative Stress

Figure 2

Effect of P. guajava var. pomifera essential oil in the locomotor activity (negative geotaxis behavior) of D. melanogaster. After treatments were finished, flies were submitted to negative geotaxis behavior test as described in Section 2. -axis represents the number of flies able to climb at least 6 cm of a glass column after 5 seconds (number of flies on top). The less the number of flies able to reach the 6 cm mark, the more affected the locomotor ability. Results are expressed as mean ± SD. compared to control at each exposure time.
