Montelukast sodium (MS) is a leukotriene receptor antagonist and used clinically as an antiasthma agent. MS has been hypothesized to have adverse effects in insects. To test this hypothesis, MS was added to the artificial diet of the fruit fly Drosophila melanogaster Meigen (Diptera: Drosophilidae) at different concentrations (1200, 1600, 2000, and 2400 mg/L) under laboratory conditions. The effects of MS on the survival rate and development time of D. melanogaster, as well as its effects on malondialdehyde (MDA) levels and cytochrome P450 monooxygenase (CYP450) enzyme activity in adults were investigated. The genotoxic effect of MS in whole adults was …
