Scales!

High populations of scale insects are drawing attention in Chicagoland. The insects, commonly called lecanium scales, feed on the sap of a variety of trees including maple, oak and many others.

Symptoms: The signs of scale infestation are often noticed before one sees the insect itself. Most noticeable is the sticky, wet substance on understory plants. This material, known as honeydew, is excess fluid that is excreted in copious amounts as the insects feed. Understory leaves and other surfaces may be lightly speckled with the shiny drops of honeydew, or they may be heavily coated with the sugary secretion and appear as if covered with shellac.

Ants, wasps and bees are attracted to the honeydew, and sooty mold fungus sometimes grows on this substrate, blackening the foliage, twigs, and bark, along with cars and other objects beneath scale-infested trees. Dieback of twigs and branches and premature leaf drop may result as heavily-infested trees compete with scale insects for necessary moisture.

Appearance: Lecanium scales can vary in size and color but are generally oval in shape. Females molt several times before reaching adulthood. With each molt, the female's body grows bigger, while her legs and antennae become proportionately smaller. By the time of the second molt, the female scale, with her hardened, brownish, hemispherical body, is incapable of moving from the spot on which she has become fixed. Male scales are delicate, flat and nearly transparent.

Tree Watering Bags

Tired of standing next to a newly planted tree with a hose and seeing most of the water running away from the tree into the grass? Then make your job easier and more effective --- use a National Seed Tree Watering Bag! The National Seed Tree Watering Bag distributes approximately 20 gallons of water around the base of the tree over a 4-6 hour period. This allows the water to be absorbed into the ground rather than run off. This is very useful when planting a new tree or watering a young tree in the dry time of the year.
