The gypsy moth has recently (2021/2022) been officially renamed the spongy moth. Kentucky is nearly surrounded by regulated, infested areas in Virginia, West Virginia, Ohio, Indiana and Tennessee. From 2000-2002, West Virginia experienced record defoliations in which over 1 million acres were affected.  The possibility of spongy moth spread to Kentucky is very high due to the popularity of Kentucky's recreational areas and the number of people moving into the metropolitan areas from the northeast. We have been surveying for this pest since 1983 and will continue monitoring due to the close proximity of spongy moth present in states surrounding Kentucky on all sides.  This extensive trapping program pinpoints potential problems so they may be quickly eradicated before they become infestations that require the expenditure of large amounts of time and money to eradicate.

Triangular delta traps are baited with a synthetic female sex pheromone to attract and capture male spongy moths every year.  Detection traps are set throughout the state, covering as much of the state as funding will allow, in order to detect moths.  Delimiting traps are extra traps set in an area which previously had several moth captures.  Slow the Spread is a program that gives funding to states to intensively trap along the leading edge of the zone which is generally infested with spongy moth to detect populations and allow for quick eradication. In 2022, we implemented a Citizen Science program in which citizens across the state set and monitored spongy moth traps.

The graph below shows numbers of moths captured each year during all survey activities combined.
