Abstract
|
|
|
In order to see if monosodium glutamate (MSG) affects the development (emergence rates) when treated it at the various larval stages (first instar larva, second instar larva, and third instar larva) of D. melanogaster, the emergence rates of the three strains of D. melanogaster.(Oregon-R, Sinchon-4 and Chunchun).
The MSG and sacchrose media were preapred by adding them at a concentration of 0.0M, 0.1M, 0.3M,0.5M, 0.7M and 1.0M to the standard media.
The following conclusions were obtained:
1) The emergence rates from the MSG media is not significantlydifferevt among the three strains but strikingly different among the concentration of MSG in each of larval stages of D. melanogaster.
2) The emergence rates decrease as the concentration of MSG increase.
3) The decrease of emergence rates is found to be rather conspicuous when treated with MSG at the first instar larval stage but not when treated it at the second and thethird instar larval stages.
4) The emergence rates are not significantly different among concentrations of saccharose, impling that no effect of saccharose on the emergence rates of D. melanogaster.
