FONG, CRISTIAN et al. Effect Of Eggs Population Density On Viability And Time Of Development Of Drosophila melanogaster (Drosophilidae). Acta biol.Colomb. [online]. 2008, vol.13, n.2, pp.123-132. ISSN 0120-548X.

For estimating the effect from population density of eggs over viability egg-adult in Drosophila melanogaster, it was made three treatments in flasks with agar-banana culture media: densities of 10, 50 and 90 eggs. The effect evaluated was the adult’s proportion that emerged after 15 days of planting. The mean proportions of viability egg-adult were 0.32, 0.338 and 0.328 for the density of 10, 50 and 90 eggs respectively. Significant differences in viability were not evident (p>0.05). Consequently, it was not found effects from the eggs densities in the present study over egg-adult viability. These results probably were due to that the relation among number of eggs and quantity of culture media was not enough of a high for generate competition at another stadiums through the egg-adult development.
