Aphids are small soft-bodied insects, which, in a big unchecked population, can cause serious damage to trees. The insects attack trees by sucking the sap out of the leaves and other tender growths on the trees.As the aphids feed, they will secrete a sticky
substance called honeydew, which may drip from the leaves and onto the ground. Aphids have also been known to spread fungal tree diseases from one plant to the next.

Apart from the honeydew, other signs of aphid infestation include inwardly curled leaves that may have turned yellow, and black sooty mold, which is actually a fungal growth on the leaves. The fruit will also attract other insects such as ants, which feed on the sticky fluid.

interrupting the flow of sap, while others will lodge and feed on the cambial tissue.Boring insects may also act as carriers for different tree diseases.

Web worms

As the name suggests, web-worms are worms, or caterpillar-like insects that weave thick, yet loose webs over tree
foliage. Web-worms are actually the larval form of a white moth which is commonly spotted over the summer. The web-worms
will stay inside the nesting or web and feed on the enclosed leaves, which may vary from a single leaf to a whole branch or cluster of leaves. Once the insects have devoured all the leaves encased within the web, the webbing will be expanded to accommodate new foliage so that the larval web-worms have more food.

Web-worms will appear in late summer and early fall, causing tree damage by contributing to heavy leaf loss
as they are aggressive leaf consumers. The webs are also very unsightly.

It is important to conduct periodic checks on the health of your trees. An early diagnosis can make a big difference in finding an effective
