Antimicrobial Silver in Maple Sap Collection

Because of a new approach to using nano-silver, the fact that PFA has been banned, and the desire to control microorganisms in maple sap collection systems, the University of Vermont Proctor Maple Research Center investigated the use of spouts and tubing containing antimicrobial nano-silver for suitability for increasing maple sap yield.

Are NASS Maple Surveys Underestimating Production?

Some have questioned the accuracy of NASS’s Maple Syrup estimates. The most common criticisms typically include: some producers don’t return their report, some don’t report accurately, and some don’t receive a report. I will address each one separately.

Asian Longhorned Beetle

This presentation by Tim Barwise (MA-DCR) the 2018 Vermont Maple Conferences covers the current infestation and the USDA-APHIS response to asian longhorned beetle (Anoplophora glabripennis) in the greater Worcester, MA area.

Asian Longhorned Beetle (Coleoptera: Cerambycidae), an Introduced Pest of Maple and Other Hardwood Trees in North America and Europe

The Asian longhorned beetle, Anoplophora glabripennis (Motschulsky), threatens urban and forest hardwood trees both where introduced and in parts of its native range. Native to Asia, this beetle has hitchhiked several times in infested wood packaging used in international trade, and has established breeding populations in five U.S. states, Canada, and at least 11 countries in Europe. It has a broad host range for a cerambycid that attacks living trees, but in the introduced ranges it prefers maples. Identification, classification, and life history of this insect are reviewed here. Eradication is the goal where it has been introduced, which requires detection of infested trees using several approaches, including ground and tree-climbing surveys. Several agencies and researchers in the United States and Europe are evaluating the use of pheromone- and kairomone-baited traps. Control options beyond cutting down infested trees are limited.

Asian Longhorned Beetle and its Host Trees

This pictorial guide provides basic information for identifying the Asian longhorned beetle, its injury characteristics, and its common host trees. The guide will help users detect the beetle in both urban and forested settings.

Ask Proctor

The leaves on the trees are still mostly green and few have fallen. Does this indicate anything for the upcoming sugar season?

Ask Proctor

Will the dry weather affect syrup production next spring?

Ask Proctor

Could the sugar maples have broken bud during unusually warm January temperatures?
