This work aimed to study spatial and temporal distributions of predatory wasps ofL. coffeella in an irrigated system. Significant differences among the predatory wasp densities, L. coffeella, and among the months of year were detected. Plants with predate caterpillars displayed spatial autocorrelation. This was also true for the density ofL. coffeella and the irrigation depths. The highest density of predatory wasps showed a correlation with the coffee leafminer population density. In general the irrigation depths had a negative correlation to the presence of predatory wasps.
