Trees are susceptible to disease, and more often than not, these diseases are caused by tree pests and parasites.Early identification of the disease-causing pests, preventing an infestation and putting in place the necessary pest control measures goes a long way in preventing tree damage and even premature deaths of trees.
Aphids, boring insects and web-worms are only three of the common pests that pose a risk for trees in Texas. Here is a highlight of what to look out for with each of these pests.
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.
Boring insects describes a category of insects consists of different species including the emerald ash borer, ambrosia beetles and the Asian long- horned beetle, just to mention but a few.
The different borer species cause tree damage in different ways. Some will tunnel and bore right into the sapwood in the tree,
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.
3. 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
treatment and management course in time, thereby saving your trees.
