Aphids are a pest that attacks pepper plants, causing poor growth and deformed leaves. This article from the โWORLD OF PLANTSโ website provides information on how to identify aphid infestation on pepper plants and effective control methods.
Causes of aphids on pepper plants
Disease name: Aphid on pepper plants
Scientific name: Aphids
The type of disease is insect
Disease family: Aphididae
These pests attach to the lower leaves of pepper plants and suck the juice from them. Aphids also secrete a sticky substance called โhoneydewโ because they absorb all the sugary liquids from the leaves. The honeydew substance is also considered food for ants.
Symptoms of aphids on pepper plants
The affected areas turn dark in color when aphids suck the sap of pepper plants, which leads to the leaves of the pepper plant deforming and dying. Ants that are attracted to the honeydew also cause deformation of the roots.
Development cycle of aphids on pepper plants
Most aphids are born pregnant, so they reproduce very quickly, with several generations during one season. The nymphs mature within 6-8 days, so one aphid can produce more than 4,400 insects in three weeks in the absence of natural enemies.
Suitable conditions for the spread of aphids on pepper plants
Aphids need dry conditions and temperatures of 20ยฐC or higher to reproduce, and they also carry phytopathogenic viruses.
Losses resulting from the spread of aphids on pepper plants
Aphids are more attracted to new leafy growth than larger, older leaves. The honeydew secreted by the aphid also poses great harm to the pepper plant, as it hinders the process of photosynthesis, which may cause the plant to die if the infestation is neglected.
Controlling aphids on pepper plants
- Most aphids cannot fly, so one of the easiest ways to remove them is to spray them with water, focusing on the affected lower parts.
- Use insecticidal soap.
- Using neem oil helps get rid of insects.
- Use chemical insecticides only in cases of severe infestation.
Preventive measures for aphids on pepper plants
- Good fertilization of the plant.
- Use species resistant to aphids.
