Aphids (Aphis gossypii and other species)
Aphids suck sap from leaves and stems. They may cause considerable damage during periods of water stress. Aphids are vectors of virus diseases.
- Conserve natural enemies. Aphids are attacked by a wide range of natural enemies, which are very important in natural control of these pests.
- Use reflective mulches. Reflective aluminium mulches deter aphids from landing on plants. The effect is lost once plants are large enough to cover the mulch.
- Neem extract and soap sprays have been reported effective against aphids.
