A study of survival of Iphiseiodes zuluagai Denmark & Muma based on Weibull's distribution showed that females longevity was greater than that of males; unmated females and males also had a longer longevity than mated ones. Mean longevity for virgin females was 27 days and of mated ones 23 days; for males these data were 14 and 8 days, respectively. Mortality rate increased with time for males and females. However, shape parameter values were near 1 suggesting a constant mortality rate.
