Eastern tent caterpillars in Central Kentucky are mature, have dispersed from trees, and are on the move, leading experts to advise horse farm managers to move pregnant mares, if practical, to avoid contact with them.
Experts report the eastern tent caterpillar egg hatch will likely begin in mid-March for Central Kentucky.
Eastern tent caterpillar eggs have begun hatching well ahead of last year's schedule, and the egg hatch is expected to be completed by the first full week of March, University of Kentucky officials said Feb. 29.
Eastern tent caterpillars have begun hatching in Central Kentucky, and their population numbers are trending up, the University of Kentucky College of Agriculture has reported.
Experts have reported that eastern tent caterpillars are now wandering and population levels are among the highest they've seen since the 2001, when Mare Reproductive Loss Syndrome hit Central Kentucky particularly hard.
Experts have reported that Eastern tent caterpillars are developing normally this spring and have just completed the egg hatch stage. Controlling the caterpillars is vital to area horse farms, as University of Kentucky research has strongly linked them with outbreaks of mare reproductive loss syndrome, which can cause late-term foal losses, early-term fetal losses, and weak foals.
A farm in northern New Jersey experienced high abortion rates in early June in fields where there were Eastern tent caterpillars.
The impact of the deadly mare reproductive loss syndrome has been minimal on central Florida horse farms this year, but experts say steps should be taken to limit future problems in the area's vast equine industry.
A second foal has been confirmed as having died from mare reproductive loss syndrome (MRLS) in Florida, according to Dr. Dana Zimmel of the University of Florida's College of Veterinary Medicine.
One confirmed case and two suspect cases of mare reproductive loss syndrome have been diagnosed in Alachua County, Fla., according to Dr. Dana Zimmel of the University of Florida's College of Veterinary Medicine.
At an open meeting at Keeneland on Tuesday, two entomologists shared their best recommendations for monitoring and reducing the ETC population.
Eastern tent caterpillars, plus bacteria and a means to infect placental fluids with the bacteria, equals mare reproductive loss syndrome. It might be as simple as that.
A research project has determined that it probably isn't a virus or bacteria (a biological agent) that links the Eastern tent caterpillar (ETC) to mare reproductive loss syndrome (MRLS).
Recent research conducted by the University of Kentucky indicates that there is something in or on the exoskeleton (skin and associated structures) of the Eastern tent caterpillar that causes horses to abort.
The Grayson-Jockey Club Foundation issued an advisory concerning control methods for Eastern Tent Caterpillars, which have been linked to mare reproductive loss syndrome in 2001 and 2002.
Central Kentucky veterinarians Richard Holder and Jim Morehead discussed MRLS and fall fetal loss syndrome at Tuesday's joint meeting of the Kentucky Thoroughbred Farm Managers' Club and the Kentucky Equine Practitioners Association.
The results of a survey conducted by the Gluck Equine Research Center showed that a small number of Central Kentucky farms experienced an unusual increase in what is being termed fall fetal loss syndrome (FFLS) during the latter part of 2002.
The University of Kentucky's Livestock Disease Diagnostic Center reports a slight rise in the number of equine abortions compared to 2002 figures. The report comes less than a week after veterinarians and scientists met for a "Think Tank" meeting on mare reproductive loss syndrome (MRLS).
President Eric Hamelback gave a sense of urgency as he opened the most recent meeting of the Kentucky Thoroughbred Farm Managers' Club, saying "we need to make plans for control now."
The University of Kentucky College of Agriculture on Friday released the results from a collaborative project involving Eastern Tent caterpillars and mare reproductive loss syndrome (MRLS).
The Kentucky Thoroughbred Farm Managers Club will host a meeting on Nov. 3 at the Embassy Suites on Newtown Pike to discuss Mare Reproductive Loss Syndrome (MRLS) in 2003.
Four interesting facts were brought to light because of the late-term abortion and Eastern tent caterpillar (ETC) study that was recently completed at the University of Kentucky, according to Dr. Thomas Tobin of the Gluck Equine Research Center:
The University of Kentucky College of Agriculture has released preliminary results from a collaborative project involving the UK Livestock Disease Diagnostic Center, the UK Department of Veterinary Science, and the Hagyard Davidson McGee Equine Hospital. This project investigated the potential of Eastern tent caterpillars (ETC) to cause fetal loss when administered to mares in the late stages of pregnancy.
Numbers from Rood and Riddle Equine Clinic in the Lexington area have helped estimate the current early fetal loss rate at somewhere between 5% and 12% for mares checked between April 30 and May 17.
A few isolated cases consistent with a diagnosis of Mare Reproductive Loss Syndrome have been identified in the last seven days, said the Kentucky Association of Equine Practitioners at a meeting May 1. The numbers are significantly less than reported for the corresponding period in 2001.
Early test results of a University of Kentucky College of Agriculture study appear to show a correlation between eastern tent caterpillars, their waste--called frass--and foal loss in mares exposed to both.
