Winter is the Ideal Time for Controlling Viburnum Leaf Beetle

Viburnum Leaf Beetle Egg Sites on Winter Twigs of Blackhaw Viburnum

December found me exploring the plant collections of two public gardens where I suspected the presence of Virburnum Leaf Beetle egg laying sites on Viburnum dentatum var venosum and Viburnum dentatum.  The presence of the beetle in southeastern PA is not new having been confirmed in many but the most southeastern of counties previously, but it was a new pest in each of these locations.  My suspicions were confirmed by PSU entomologists.
