Aphids are sucking insects that feed on plant fluids. The presence of aphids or white cast-off skins on leaves or flowers may reduce plants value. Heavy infestations will reduce plant growth. Honeydew produced by aphids makes leaves and fruits sticky and is a substrate for black sooty fungus. Many aphid species transmit viruses affecting vegetable and ornamental plants.

Aphid developmental stages are egg, nymph and adult. In greenhouses and tropical areas, adults are all females that produce live young. Outdoors, aphids overwinter as eggs, which hatch in the spring as females. Adult aphids may or may not have wings. The best temperatures for development vary with the species. For example the chrysanthemum aphid develops best at 68°F (20°C), the green peach aphid at 73°F (23°C), and the melon aphid at temperatures above 75°F (24°C). Plant nutrition affects aphid development and size. Moisture stress often increases aphid numbers. Temperatures above 86°F (30°C) and humidities above 85% reduce green peach aphid longevity and reproduction.
