Aphids

imgresAphids are starting to be found on a variety of plants already. Symptoms of aphid feeding are cupping, twisting, and wrinkling of new stems, leaves, and/or flowers.  Damage can result in stunting, leaf browning, and leaf drop. Aphids also produce a sticky excretion that turns black as a result of sooty mold fungus.

A single aphid is fairly easy to control, but a large population can be difficult. Since reproduction occurs rapidly, a population can rebound quickly after being controlled. Aim controls at reducing aphid populations to where the damage caused by aphids is at an acceptable level.

Lady beetles, hover fly larvae, various parasitoids and green lacewings are predators of aphid populations. Insecticidal soap or horticultural oil can be of use to help control  aphids  if needed.
