As I ride through the county I’ve noticed some webs are back in the wild cherry trees but before you start having nightmares about the webbing we had last fall, you can rest assured that this insect is different.  This culprit is the Eastern Tent Caterpillar. The webs serve as a home to the newly emerged larvae or as we like to call them, caterpillars. The eggs are timed to hatch when the cherry buds unfurl as they need to eat to grow and complete their life cycle.

Older larvae are generally black, with long brown hair and a white stripe down the middle of their backs. Along the midline is a row of blue spots with brown and yellow lines. At maturity, the caterpillars may reach a length of 2½ inches. The adults are reddish-brown moths which have two white oblique stripes on each forewing.  These are harder to notice, but they are the final step in the life cycle.

The adult moths emerge in May and early June and lay egg masses that resemble chocolate-colored collars that encircle the smaller limbs of their host. Each egg mass is about 1 inch long. Eggs overwinter and hatch in mid-March of the following year to start the cycle again. From each egg mass, several hundred tiny feeding machines emerge, and for four to six weeks they hungrily strip the trees of their leaves. The larvae are gregarious and upon hatching they gather in the forks of the limbs and develop the web that can be seen in the trees.  This serves as their home for the larvae. From this mass of silk, the developing larvae move outward to feed on developing leaves, but they return at night and during rainy weather. The nest gradually becomes larger and larger as silk accumulates. Although the nests are most commonly seen in the forks of wild cherries, this pest can be found in other ornamental, shade and fruit trees, especially apples. While not a serious pest in the natural forest, the unsightly web insect can reduce the beauty and esthetic value of shade trees and other hardwoods in the landscape.

About four to six weeks after hatching, full-grown larvae will crawl away from their nests and accumulate on the sides of homes, on driveways and sidewalks and on various woody ornamentals in search of sites to complete the next phase of life, the pupae phase.  This phase is a shell or cocoon in which the caterpillar matures into a moth. There is concern that they may be attacking other plants, but when they do leave their web, the larvae are finished with their feeding and will do no damage to plants on which they are found. The caterpillars are primarily a nuisance and do not usually pose a danger to the overall health of a larger, well-established tree as the tree can produce another flush of foliage.  However, young fruit and ornamental trees may be damaged, so it is a good idea to remove the web from these trees.

Usually, no chemical controls are necessary or very effective.  One reason is that the web is water proof and insecticides that are applied usually do not reach the larvae but you can break open the web and apply an insecticide such as carbaryl (Sevin), BT or a pyrethroid if you would like. If you decide to use an insecticide, please read the label and follow the instructions.  In addition, the egg masses can be clipped from the limbs in late June to prevent nests from developing the following spring.

Whether you’re a new, beginner or veteran homeowner, landscaper (perhaps your own company) or golf course superintendent, you’ll find the latest research-based information on growing and maintaining Turfgrass at this year’s Turfgrass Research Field Day on the UGA campus in Griffin, GA on Thursday, August 9th.

The University of Georgia College of Agricultural and Environmental Sciences (CAES) researchers and UGA Extension specialists will present the latest information on how to care for residential lawns, commercial golf courses, athletic fields and any other space covered with Turfgrass.

Field day topics will include how to control weeds, insects and diseases, managing seed heads, heat and drought tolerance and an update on the UGA Turfgrass breeding programs.

A catered BBQ ribs and chicken lunch will be followed by product exhibits and demonstrations of the latest Turfgrass industry equipment. A self-guided research tour begins at 1:15 pm with at least half dozen programs to choose from. Guided tours will be offered in Spanish for Spanish-speaking attendees.

Registration is from 8:00 to 8:45 am followed by the welcome and presentations plus information regarding the available tours.  To view the Turfgrass research plots, the event is held outdoors, rain or shine, so dress appropriately and bring sunblock. The day concludes at 2:30 pm.

Pre-registration is required for the $65 individual fee ($25 for students) before July 17th. After that deadline, fees increase to $80 and $30. Receive a 10% discount for four or more registrants. The registration fee includes instruction, research tours, demonstrations and exhibits, Turfgrass research field day guide and lunch.

Are some of your plants suddenly dying?  Did the tulips forget to bloom this spring?  After you hunted for some bulbs, did you find little tunnels in and around your flower beds?  If so, you may be a victim of the pine vole.

Often confused with moles, pine voles can be found in underground tunnels.  In fact, they may use mole runs just to make it easier to move around. Pine voles are usually 4 to 6 inches in length and are covered with brown, dense fur with a bicolored tail.  Their under parts are gray.

Pine voles prefer areas with a heavy ground cover of grasses.  They like living in deciduous and pine forested areas, abandoned fields and orchards.  They will eat grasses, seeds, tubers, bulbs and any underground growing part.

There are 23 vole species across the country.  They can cause extensive damage to orchards, ornamentals and trees due to their girdling of seedlings and trees.  Girdling usually occurs in fall and winter. The easily identifiable sign of voles is numerous burrow openings of about an inch around shrubs and flowers.  Voles are active day and night, year round, and they do not hibernate during the winter. Their “home” range is usually ¼ acre or less.

Moles, on the other hand, are found throughout a lawn or garden.  They have runs and push up soil just like the voles, but they do not come out of the ground.  They stick to a diet of grubs and other crawly creatures found in the soil, and they will sometimes kill plants as their tunnels will create air pockets that roots cannot live in, so proper identification of the mammal is important.

After identifying the culprit, controlling these rodents can be challenging.  Keeping grass in an area short helps with control because they do not like to move across open areas because of flying enemies.  Frightening devices or repellents generally do not work and although owls, snakes and hawks are predators of voles, they seldom control vole populations.  However, trapping, using a mouse snap trap, is effective along an active run during the winter. Favorite baits are peanut butter-oatmeal mixtures or apple slices.  Place several traps around a hole and cover it with a box to fool them with shelter and prevent pets from getting in the traps and if by chance one gets into a home, setting a snap or live trap as you would for house mice results in successful control.

If you are seeing the pushed up soil runs made by moles, there are two basic types of control.  There are harpoon traps that can be placed over an active run, but these are very tricky to use.  The most effective control has been to apply granular insecticides labeled to kill grubs. These will limit the moles food source and they will leave the area if they don’t have anything to eat.  The down side to this method is that the granules will also kill the beneficial critters that live in the ground. Remember when using any insecticide to always read and follow the label directions.
