- Common name: Cabbage Aphid
- Scientific name: Brevicoryne brassicae (Linnaeus)
- Family or class: Aphididae
Symptoms and/or signs to watch out for:
- Leaves curling around dense colonies
- Aphids damage the plant by building up in dense, sticky clumps
- Life cycle 16-50 days, shorter at higher temperatures
- Can be 15 generations in one season
- Peak populations in mid-August and mid-October
Mode of reproduction:
- Adult females give birth to live offspring throughout growing season
- During warm periods females do not need to mate
- In fall, males are produce and they mate and lay eggs
Vectors for the pest:
- Surrounding brassica weeds like wild mustard
- Eggs laid in plant debris near the soil surface
- Any other brassica plant, including weed species
Horticultural production information:
- Destroy crop remnants after harvest
- Remove brassica weeds
- Plant wild-flower habitats to attract natural enemies
- Remove heavily infested plants entirely
- Control is more than 10% plant is infested
- See sequential sampling chart on UC IPM Pest Maagement Guidelines: Cole Crops
- Limit Nitrogen fertilization
- Remove heavy infestations
- Polycropping with beneficial flowers
- Squish them by hand
- Syrphid flies
- Parasitic wasps
- Lacewing larvae
-Azera, M-Pede, peppermint leaf extract, seed extract from the Chinaberry tree
