AphidsAphids have piercing mouthparts where they remove plant fluids from your tree. Aphids come in several colors, including green, white, and black, and can generally can be recognized by their small size, pear-like shape, and long antennae. They are sometimes ‘herded’ by ants and so the presence of ants in a tree can be an indicator of aphid infestations.
Aphids harm the tree by removing plant fluid, spreading disease, and can stunt growth and cause deformed leaves and fruit. Aphids also secret a “honeydew” that causes mold to grow on your trees which can effect photosynthesis and attract other harmful insects.
