Rodney N Nagoshi    Research Geneticist (Insects) nagoshi735.jpg Dr. Nagoshi is a recognized expert in insect genetics and reproduction with 
professional experience in both academic and government science.  He 
has been awarded several nationally competitive research grants including those 
from the NIH and USDA, and has developed and taught numerous courses at the 
undergraduate and graduate levels in genetics, molecular biology, and developmental 
biology.  Dr. Nagoshi has worked extensively on the genetics of insect 
oogenesis and sexual differentiation.  At present he is collaborating 
with unit ecologist, Dr. Meagher, on work that centers on describing the genetic 
structure of fall armyworm populations, a major international economic pest.  The 
objectives are to develop tools to monitor and predict population movements, assess 
the probability and magnitude of infestations, and ultimately to modify these 
populations to mitigate future infestations. The research entails the development of a novel application of haplotype analysis 
that can distinguish between different migrant fall armyworm populations.  This 
methodology is being used to map migration from overwintering sites and will be part 
of collaborative efforts to identify the biological, behavioral, and environmental 
factors that dictate these distribution and movement patterns.  The findings 
will be used to develop methods to predict the timing and severity of infestations 
in specific crops and suppress migrating populations at their overwintering 
source.  The successful completion of the research plan will define the 
migratory pathways of fall armyworm in North America and identify indicators for 
predicting the timing and severity of the infestations.  This will be of 
significant use to growers with respect to decisions about the timing of pest control 
efforts and be of broad interest to researchers studying insect migration.  The 
extension of this study to include the Caribbean, and portions of Central and South 
America will be instructive for how migratory pests might enter the United States.  The 
data obtained will define the geographical and temporal extent of any proposed area-wide 
management strategy and drive the development of techniques designed to disrupt or 
delay the northward migration of fall armyworm and thereby mitigate its economic consequences. Collaborators:Shelby Fleischer, Professor, The Pennsylvania State University, University Park, PA
