Eastern tent caterpillar egg hatch begins in Central Kentucky

LEXINGTON, Ky. (March 26, 2015) – Eastern tent caterpillar egg hatch was reported March 23 in Scott County.

According to Lee Townsend, University of Kentucky College of Agriculture, Food and Environment extension entomologist, the tiny larvae will continue to emerge over the next two weeks from eggs laid last summer on flowering wild cherry, cherry, apple and related trees.

The eastern tent caterpillar spends the winter as tiny, fully-developed insects in distinctive egg masses that encircle twigs of wild cherry and related trees. It is one of the first insects to become active in the spring and is well adapted to survive Kentucky’s erratic winter and early spring weather.

“This is a hardy insect, so it is unlikely that our winter temperatures caused much mortality,” Townsend said. “Studies have shown that caterpillars in the egg can withstand temperatures down to 31 below zero Fahrenheit.”

Populations of eastern tent caterpillars have been climbing over the past few years. This trend is likely to continue, he said, producing locally high numbers in some areas. The rise in numbers is normal and mirrors the cyclical aspects of insect populations in general. According to Townsend, eastern tent caterpillar cycles are roughly 10 years in length. After two or three high years, the numbers usually drop again due to diseases or natural enemies.

When mature, the large, hairy caterpillars wander from their developmental sites along fence lines. Consumption of large numbers of caterpillars by pregnant mares precipitated staggering foal losses in the Mare Reproductive Loss Syndrome outbreak that peaked in 2001. MRLS can cause late-term foal losses, early- and late-term fetal losses and weak foals. Studies by UK researchers revealed that horses will inadvertently eat the caterpillars, and the caterpillar hairs embed into the lining of the alimentary tract. Once that protective barrier is breached, normal alimentary tract bacteria may gain access to and reproduce in sites with reduced immunity, such as the fetus and placenta.

Horse owners and farm managers with pregnant mares should begin to monitor fence lines containing wild cherry trees in about two weeks for small tents produced by developing caterpillars.

If practical, farms should plan to move pregnant mares from areas where these trees are abundant to minimize the chance of exposure to the caterpillars. The potential is greatest when the mature tent caterpillars leave trees and wander to find places to pupate and transform to the moth stage.

To get rid of active caterpillars, Townsend recommends pruning them out and destroying the nests as they are seen, if practical. Any one of several biorational insecticides registered for use on shade trees can also be used to treat as needed. Spot treatments to the tents and/or the foliage around them can be applied according to label directions, which vary by product.

Study finds common equine parasite misidentified in textbooks

By Jenny Evans

LEXINGTON, Ky., (March 23, 2015) – A recent study led by Martin Nielsen, assistant professor at the University of Kentucky Gluck Equine Research Center, found that all veterinary medicine textbooks have misidentified a common equine parasite.

The large equine roundworm Parascaris equorum, commonly referred to as the ascarid, which is known for infecting foals, is actually a different species—Parascaris univalens. The research suggests P. univalens is the main species now observed in equines. The broader designation Parascaris spp. should be used instead unless cytological characterization (a technique for characterizing chromosomes) has confirmed the species.

“Parascaris univalens is really the forgotten parasite,” Nielsen said. “It is almost never mentioned in the textbooks, and most people have only heard about one roundworm species infecting equids.”

  1. univalens was discovered more than 130 years ago. The species only possesses one germ line chromosome pair as opposed to two for P. equorum, but the two species are otherwise considered structurally identical.

“We really wanted to find specimens of both species to study and find differences in their DNA,” Nielsen said. “The only way to tell them apart is to look at their chromosomes, so we invited a leading expert, Dr. Clara Goday, to the Gluck Equine Research Center to teach us the delicate technique of parasite karyoptyping.”

Karyotyping is a technique to study and characterize chromosomes in a sample of cells.

For the study, 30 live worms were obtained and dissected. All of the samples were identified as P. univalens. Then, the karyotyping technique was performed on ascarid eggs from foal fecal samples. P. equorum was not identified among these, whereas P. univalens was found in 17 samples, with the remaining eight being inconclusive.

“We were part of another study analyzing numerous Parascaris specimens from several different continents, and the conclusion there was that only one species was found,” Nielsen said. “We compared genetic information obtained for P. univalens in our study with gene codes already published as P. equorum and found that they were probably mislabeled.”

Others from the UK Gluck Center involved in the study were Jennifer Bellaw, a doctoral student in veterinary science; Eugene Lyons, professor; and Teri Lear, associate professor. The group from the UK Gluck Center collaborated with Jianbin Wang, assistant professor, and Richard Davis, professor, University of Colorado School of Medicine; and Clara Goday at Centro de Investigaciones Biologicas in Spain.

The article was published in the December issue of Parasitology Research.

The mission of the Gluck Center, a UK Ag Equine program in the College of Agriculture, Food and Environment, is scientific discovery, education and dissemination of knowledge for the benefit of the health and well being of horses. The Gluck Center faculty conducts equine research in six targeted areas: genetics and genomics, infectious diseases and immunology, musculoskeletal science, parasitology, pharmacology/toxicology and reproductive health.
