The overall objective of our research program is to develop and improve insect pest
management practices for row crops in southeast Arkansas. Selected ongoing projects
are outlined below.
Sugarcane aphid in grain sorghum
The sugarcane aphid, which can be a devastating pest of grain sorghum, was found infesting
sorghum in Arkansas in 2014. While it has been present in the U.S. for some time as
a pest of sugarcane, it has only been documented in sorghum at economically damaging
levels in the U.S. since 2013. Little information is available on the best management
practices for this insect in sorghum, and most of the insecticides labeled for use
in sorghum are ineffective. We are collaborating with other researchers in Arkansas
and throughout the affected region to develop management recommendations for sugarcane
aphid. Early efforts will focus on developing an economic threshold, evaluating insecticides
and application methods for chemical control, and determining the impact of cultural
practices such as planting date and variety on sugarcane aphid populations.

Opportunities for Students
Graduate Student Opportunities
Opportunities to pursue a graduate degree in entomology through the University of
Arkansas Department of Entomology are periodically available. Research would typically
be conducted at the Southeast Research and Extension Center in Monticello, AR and
the Rohwer Research Station near Kelso, AR, with coursework taken through the University
of Arkansas main campus at Fayetteville. Prospective students should send a copy of
their C.V. and a brief statement of research interests and career goals to Nick Seiter
(firstname.lastname@example.org). For more information on the University of Arkansas Department of Entomology and
its graduate programs, please visit http://entomology.uark.edu.
Undergraduate Student Opportunities
The entomology program at the Southeast Research and Extension Center hires seasonal,
hourly workers in the summer to assist with field research activities, including plot
maintenance and data collection. Priority is given to students in the University of Arkansas at Monticello School of Agriculture, but any interested students are encouraged to apply. Please contact Nick Seiter
(email@example.com) or Brett Stewart (firstname.lastname@example.org) for more information.
