Invasive Pest Targeted By PA Agencies

October 21, 2004 - By Pennsylvania IPM Program 

UNIVERSITY PARK, PA - An exotic pest is invading Pennsylvania at an
increasing rate, while state agencies are working together to bring
awareness and combat the problem. 

The Brown Marmorated Stink Bug (BMSB), long a pest in its native Asia,
is a new invasive agricultural pest of stone fruit, especially peaches
as well as many other plant species. It was first detected in North
America in Allentown, PA in 2001. In addition to being a strong flyer,
BMSB is a hitchhiking pest that has the potential to spread rapidly with
human assistance to other locations in the United States. The insect is
also considered a nuisance pest, especially in the fall, when adult BMSB
enter homes looking for a place to over winter. 

Invasive species are organisms that adapt quickly to a new environment
and reproduce and spread rapidly into new locations, often displacing
the organisms that were originally there. "Many invasive species are
exotic-not native to our environment, while others may be native, but
may rapidly reproduce and become a problem," says Gary Clement, state
director for APHIS, PPQ. 

BMSB adults emerge in spring, mate and lay eggs from June to August.
BMSB grows to adulthood during July and August with the adults searching
for overwintering sites in September, often in homes and other human
structures. There is probably only one generation per year in

During the summer BSMB has been observed feeding on shade trees, fruit
trees, vegetables, legumes and many other plants. Since this bug has
'piercing-sucking mouthparts, it damages plants leaving many areas of
stippling or dead areas on leaves and fruit. Clement says PPQ recognizes
public education and outreach as a critical component of their overall
pest detection program. "Education and outreach will go a long way in
helping us to focus on rapid detection and identification of invasive
species," said Clement. 

To this end, a new brochure on BMSB was recently developed and is now
available through Penn State Cooperative Extension. The four-color
brochure contains information on the biology of the insect, the problems
they can cause and management tips, along with four-color images of the
insect at its various life stages. John Berry, extension educator at
Lehigh County Cooperative Extension, developed the brochure after seeing
the need to educate growers and the general public about BMSB and its
potential impacts. "The brochure will also aid in enhanced pest
monitoring and best management practices," says Berry. The brochure is
also available in Spanish. Copies of the brochure may be obtained by
contacting the Lehigh County Cooperative Extension office at (610)
391-9840. It is also available as a downloadable PDF file from the PA
IPM Web site at http://paipm.cas.psu.edu/pdf/bmsbug.pdf

The Pennsylvania IPM program, a collaboration between the Pennsylvania
State University and the Pennsylvania Department of Agriculture, is a
partner with USDA/APHIS to communicate with the general public about the
occurrence and impact of invasive species. PA IPM promotes integrated
pest management in both agricultural and nonagricultural situations. For
