These little pests- which can come in a multitude of colors- suck the sap of plants. This both weakens the plant and can deform it. Buds sometimes cannot open. The sticky honeydew they leave behind attracts sooty mold which covers the leaves, looks unsightly and would affect the plant's ability to photosynthesize. Also they can spread viruses as they pierce the plant and allow the disease access.

∙ 10y agoTaking sap, transmitting pests, undermining well-being, and wrecking appearancesare ways in which aphids harm plants.
Specifically, aphids have sucking mouthparts for to remove hormone- and mineral-enriched watery solutions (xylem sap) moving upward from roots and hormone-, mineral- and sugar-enriched watery solutions (phloem sap) moving downward from leaves. They simultaneously may vector bacterial, fungal and viral pests since they break into and weaken such critical protective plant parts as leaves and shoots. Such actions run counter to overall plant health since life-sustaining resources must be directed to fighting invasives and toxins transmitted by an aphid's "bite." They also will detract from the plant's exterior appearance through browning, curling, mottling, yellowing leaves; covering plant foliage with ant-attracting, sticky honeydew; and stunting growth.
