Can I Prune an Ash Tree After May 1?
EAB Gallery in 1" Branch
 |
The short answer is yes, though
it isn't recommended if the tree in question is in the immediate vicinity of
trees that have previously been confirmed infested with EAB. Areas with
confirmed infested trees (Known EAB-Infested Areas) are defined on a block by
block basis - a map is available here: http://gis.mda.state.mn.us/eab/
and as new areas are added to the map they are publicized in this newsletter.
Both the pruning and removal of
ash is not recommended in Known EAB-Infested Areas during summer due to the
risk of adults emerging from the material while in transit or at a disposal
location. There is no evidence that pruning an ash makes it more attractive to
EAB.

Flight Season Countdown
Eric R. Day, Virginia Polytechnic Institute and State University, Bugwood.org | There are only a few weeks left till the official start of the flight season!
Initial emergence of EAB adults from trees is anticipated after
accumulation of 450 degree days (base 50 degrees Fahrenheit). A degree day is a
measure of accumulated heat and in this case provides a means to track how much
development time EAB immature stages (within trees) have had.
Degree day accumulations are used to track development of other insects as
well, including a common insect in the Midwest - the European corn borer.
European corn borer degree days are calculated on the same scale as EAB (base
50 degrees F) and a map for the Minnesota / Wisconsin area is available online
at:
http://www.soils.wisc.edu/wimnext/corn/euroborer.html
When an area reaches 450 degree days for European corn borer, then initial EAB
flight can also be anticipated.

EAB Train-the-Trainer & Community Preparedness Workshops
In
complimentary but separate workshops the Minnesota Department of Agriculture, Minnesota
Department of Natural Resources, and the University of Minnesota are
collaborating to further help Minnesota prepare for EAB. In the morning, from 9:00
AM to noon, will be the EAB Train-the-Trainer Program, designed to train
participants to present EAB information in their community. In the afternoon,
from 1:00 - 4:00 PM, will be the Community Preparedness Workshop, the goal of
which will be to provide community leaders with the information and resources
they will need to prepare an EAB Community Preparedness and Response
Plan. Together
these workshops will provide full community preparedness coverage, from the
community activists to the community leaders. Workshops
will be held in June of 2010 throughout Minnesota, specific dates and locations
will be announced at a later time. Please visit: http://www.mda.state.mn.us/grants/grants/fprappropriation/eabworkshops.aspxfor
more details and to register online. For
