WHO CAUSES IT?
Myzus persicae, Aphis gossypii, Macrosiphum euphorbiae and Aulacorthum solani are common species of aphids that affect lettuce crops. These insects are small and soft-bodied, with long, thin antennae. They reproduce quickly and can cause significant damage to plants by feeding on their sap. The life cycle of aphids includes several stages: egg, nymph and adult. Females give birth to live nymphs without mating, which contributes to their ability to reproduce quickly. Aphids can be vectors of viral diseases and transmit them from one plant to another during their feeding.
SYMPTOMS
Aphids cause damage to lettuce plants by feeding on their sap and secreting toxic substances, which can weaken the plants and affect their growth and development. General symptoms include deformation of the leaves, the formation of insect colonies on young shoots, the presence of honeydew on the leaves, and the transmission of viral diseases.
