EFECTO DE DENSIDAD POBLACIONAL DE HUEVOS SOBRE VIABILIDAD Y TIEMPO DE DESARROLLO DE Drosophila melanogaster (DROSOPHILIDAE)

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.
