Effects of MZ exposure on survivorship, negative geotaxis. (a) The number of survival flies exposed to MZ was daily registered and expressed as percentage of survival flies with respect to the control group (ten flies were evaluated; an experiment was performed in triplicate). The statistic was performed by comparing the survival curves with a log-rank (Mantel-Cox) test. (b) After 15 days of exposure to MZ, negative geotaxis was evaluated. Results are presented as means ± SEM, P < 0.001 from 3 different preparations. ^∗∗∗P < 0.001.
