Brevicoryne brassicae

Brevicoryne brassicae, commonly known as the cabbage aphid, is a species of aphid that primarily feeds on plants in the Brassicaceae family. This small insect is a significant pest in agricultural settings, causing damage to crops such as cabbage, broccoli, and mustard greens.

Description

Brevicoryne brassicae is a small aphid species, typically measuring around 2 millimeters in length. It has a soft body and is usually green or yellow in color, although color variations can occur depending on environmental factors.

Habitat and Distribution

Cabbage aphids are found in various regions around the world, particularly in temperate climates where their preferred host plants grow. They can be commonly found in agricultural fields, gardens, and greenhouses where Brassicaceae plants are cultivated.

Life Cycle

The life cycle of Brevicoryne brassicae consists of several stages, including egg, nymph, and adult. These aphids reproduce rapidly, with females giving birth to live young without the need for mating. This asexual reproduction allows for quick population growth under favorable conditions.

Damage and Control

Cabbage aphids feed on plant sap by piercing the leaves and stems of their host plants. This feeding behavior can lead to stunted growth, wilting, and the transmission of plant diseases. To control infestations of Brevicoryne brassicae, various methods can be employed, including the use of insecticidal soaps, natural predators, and cultural practices such as crop rotation.
