The most common aphids are the cotton aphid (Aphis gossypii), green peach aphid (Myzus persicae), tobacco aphid (Myzus nicotianae), potato aphid (Macrosiphum euphorbiae) and the foxglove aphid (Aulacorthum solani). They can damage horticultural crops, public green and gardens.
The aphid sucks the sap weakening the plant. The saliva and other substances they inject into the plant can transmit viruses and produce malformations. The honeydew they produce makes the leaves and fruits dirty and reduces their commercial value. Sooty mould grows on the honeydew and makes difficult the photosynthesis process of the plant.
It attacks mainly tomato, pepper, eggplant, cucumber, courgette, bean, melon, watermelon, strawberry, rose and gardens.
