In New Zealand it also contributes to the control of adventive leafminer flies that feed on native plants, though it also kills native leafminer flies in native habitats. The conditions for optimum performance will be between 75-90 F with a relative humidity of around 80%. Adult females will also feed on host larvae as a source of protein in order to produce more eggs (usually the smaller host larvae that are not large enough to support its eggs).
