WHO CAUSES IT?
Aphis fabae and Myzus persicae are two species of aphids that affect beets. Aphis fabae, known as the black aphid, has a shiny black oval body. Their cycle begins with viviparous females that give birth to young without having to mate. These offspring mature quickly and, under favorable conditions, can produce several generations in a single season. Myzus persicae, the green peach aphid, has a similar cycle, with females giving birth to live young. Both aphids can develop wings when population density is high or when food resources are scarce, allowing them to disperse to new host plants. The winged females find new plants and establish colonies, continuing asexual reproduction. With the arrival of autumn, some individuals develop wings and migrate to alternate host plants, where they mate and produce winter-hardy eggs. In spring, the eggs hatch and the cycle begins again.

SYMPTOMS
The infestation of Aphis fabae and Myzus persicae in beet causes direct and indirect damage. Direct damage is due to the suction of sap, which weakens the plants and affects their growth. Indirect damage occurs through virus transmission and the production of honeydew, which facilitates the growth of sooty mold fungi, darkening the leaves and reducing photosynthesis.
- Deformed and curled leaves
- Yellowing of the leaves
- Presence of sticky honeydew on the surface of the leaves
- Development of sooty mold fungi on molasses
- Delayed growth and general weakening of the plant
- Loss of vigor and decreased crop yield
- Transmission of viruses such as cucumber mosaic virus and beet yellow vein virus
TEMPERATURE AND HUMIDITY
15°C - 25°C

TRANSMISSION ROUTES
Wind, Direct contact between plants, Contaminated agricultural tools, Movements of infested plants

Recommendations
- Regularly monitor plants to detect the presence of aphids in early stages.
- Promote the biodiversity of the environment to encourage the presence of natural enemies such as ladybugs, lacewings and parasitoid wasps.
- Implement cultivation practices such as crop rotation and the use of physical barriers.
- Apply horticultural oils and insecticidal soaps to control populations in the early stages.
- Use yellow sticky traps to capture winged aphids and reduce their spread.
- Maintain the cleanliness of the field by eliminating weeds that may serve as a refuge for aphids.
- Avoid excessive use of nitrogen fertilizers, as they can favor the development of aphids.
- Introduce repellent plants such as garlic and coriander on the edges of the beet fields.
- Apply selective insecticides following the recommendations for integrated pest management.
- Evaluate the effectiveness of treatments and adjust control strategies as necessary.
