Abstract

Abstract:

The effects of methyl paraben (MP) on the fecundity and growth and development of Drosophila melanogaster were studied in this experiment. After methyl paraben was administered to Drosophila melanogaster at different concentrations, the egg number produced by parental and filial generation, the period of development, the number of pupa and eclosion and the bodyweight were analyzed. The results showed that 0.2 percent of methyl paraben has obvious toxicity effects on Drosophila melanogaster but lower concentration of methyl paraben has potential estrogenic activities. 0.2 percent of methyl paraben decreases the number of egg, pupa and eclosion, the bodyweight of male and delays the period of development. 0.02 percent of methyl paraben increases the number of egg, pupa and eclosion and shortens the period of development.

Key words: methyl paraben (MP), Drosophila melanogaster, toxicity, estrogen
