Aphidoletes are used to control aphids indoors in commercial greenhouses and interior plants as well as outdoors in orchards, shade trees, roses and home gardens. For orchards use Aphidoletes per tree. Statistical tests were conducted on log-transformed data, though arithmetic means and SEs are shown.

At all plant stages, aphid species had a significant effect on the number of predator eggs laid.
