Biological Controls in IPM

Add beneficial predators to the landscape:

  • When their overall populations are not sufficient to control a pest
  • When you anticipate an infestation at a particular time of the year

Conserve and protect beneficial predators in the landscape:

  • Encourage plants that provide shelter or an alternate food source for the beneficial species
  • Minimize disturbance to the soil
  • Use narrow range pesticides that only target the pest

Everyone knows the important predator, the Lady beetle! They feed on small pests such as aphids, mites, and thrips. Keep in mind that they come in shades of black and brown as well as red, and some do not have spots. If in doubt, look for their distinctive shape and quick movement looking for prey. Some may not recognize the Lady beetle larvae, which are also voracious predators. They are longer, flattened and are commonly in shades of black and blue with orangey spots, although there is a species that is white and waxy. The yellow eggs are found in clusters.

Brown and green lacewings are small insects with lacy wings that feed on small soft-bodied pests such as aphids, mites, and mealy bugs. The larvae, also called aphid lions, are long, brownish, with large mandibles and are also great predators for the pests. The eggs of the green lacewing are distinctive; they are laid at the end of a thin stalk descending from a leaf. Eggs of the brown lacewing are laid directly on the leaves.
