What are Aphids?
Aphids or “plant lice” may infest almost any plant. They are more commonly found on camellia, crape-myrtle, gardenia, hibiscus, ixora, oak, oleander, ornamental grasses, palm, rose, as well as nearly all annual plants. Aphids have piercing-sucking mouthparts and cause damage by sucking the plant juices. However, their ability to transmit plant viruses may be more harmful than any direct feeding damage. Aphids are soft bodied pear-shaped insects generally less than 1/8 inch long. They may be green, black, brown, pink, yellow, blue or creamy-white in color. Most aphids are wingless but when colonies become overcrowded or the host plant becomes undesirable, winged forms are produced which establish new colonies. Aphids have two short cornicles or tubes at the end of their bodies, or spots to indicate where the corricles should be. These insects are commonly found on the stems or undersides of young leaves in small colonies.Most aphids feed on the new plant growth. Their feeding makes the leaves curl or crinkle and flower buds may become hardened, causing the flowers to be distorted. Aphids have complex life cycles, and some species may alternate generations on different hosts (e.g., a tree and then a grass species). These pests are unlike many other insects in two ways: almost all are females that reproduce without mating, and most give birth to living young instead of laying eggs. Aphids have the ability to reproduce rapidly and there are many generations per year. Each female aphid produces 50 to 100 daughters during her life span and each daughter can reproduce within 6 to 8 days. Aphids as well as soft scales, mealybugs, and whiteflies excrete large amounts of honeydew which provides an excellent medium for the growth of a black fungus called “sooty mold.” Besides being unattractive, sooty mold may interfere with photosynthesis and retard plant growth. Sooty mold usually weathers away following control of an insect infestation. Ants feed on the honeydew and when ants are observed, plants should be examined closely for these sucking pests.
PEST CONTROLThere are various insecticides that can be used to control aphids, including synthetic insecticides and plant extracts/products that are thought to be more eco-friendly.
