Issue no. 17 of the Home, Yard & Garden Newsletter is now available
IN THIS ISSUE:
=================================
This is the last of the every other week issues of this
year's Home, Yard, and Garden Pest Newsletter. The next issue will be the last
one for this year and will be available around October 22, 2012. The last issue
will contain the index to topics addressed during this year's issues.
---------------------------------------------------------------
Plan on attending the 1st Annual Illinois First Detector
Tree Pest Training Program. Ten great reasons are outlined in this article.
---------------------------------------------------------------
Thanks to the Illinois IPM Grant, many University of
Illinois Specialists have been busy creating a series of online training modules
which cover pertinent pests, weeds, and diseases. Topics will focus on newly
emerging, exotic, or invasive pests as well as pests which have generated
significant questions or concerns.
---------------------------------------------------------------
Whiteflies are being found commonly in the landscape,
feeding on the leaves of flowers and other herbaceous plants as well as
hydrangea, other shrubs, and trees. Generally, late season whiteflies can be
ignored, as they are too late to cause serious damage to plant health or even
cause obvious aesthetic damage.
---------------------------------------------------------------
Boxelder bugs are common every year, but are very
numerous this year. Their numbers are typically much larger in hot, dry years,
so their larger numbers this year were expected.
---------------------------------------------------------------
Over the summer and especially the last few weeks,
detections of spotted wing Drosophila, Drosophila suzukii, and reports of
larval damage to fruit have been increasing in Illinois and nearby states
including Iowa, Wisconsin, and Minnesota. Infestations have posed problems in
Michigan since 2010. In Illinois, the list of counties where this is insect has
been collected include Pope, Union, and Marion in the southern part of the
state, Champaign, Tazewell, and Adams in the central part of the state, and
Ogle County in the north. It likely is present in most if not all of the
counties in Illinois.
