ABSTRACT
Objective To study the effects of monosodium glutamate on viability and fertility of filial generation Drosophila.Methods Different concentrations(15,30,45 g/L)of L,H,T monosodium glutamate(MSG)were added in the medium for wildtype Drosophila melanogaster,and the non-MSG medium was taken as the control group,3 pairs of Drosophilas in each bottle and 3 repeats in each group,the first and second filial generation adult Drosophila's eclosion time(growth period) and the number of offspring within 7 days(reproduction quantity),and the death count in 30 days of 20 Drosophilas were observed and recorded.Results Compared with the control group,the reproduction quantity of Drosophila significantly increased,the growth period shortened in the first filial generation in 15 g/L of T MSG group.As the MSG concentrations increased,the reproduction quantity reduced significantly,the survival rate of Drosophila in 30 days declined significantly.The reproduction quantity in second filial generation increased at the initial stage of exposure and then decreased as the MSG concentrations increased.Conclusion The results of the present paper indicates that low-dose of MSG may be the advantage for survival and reproduction of Drosophila,but high doses will produce adverse effects.
