First Place – Hilliary E. Hodgon. Binary mixtures of pyrethroids crosstalk between voltage-sensitive calcium and chloride channels in isolated presynaptic nerve terminals from rat brain. H. E. Hodgdon, R. K. Frisbie, J.M. Clark; University of Massachusetts, Amherst, MA.

Hilliary Hodgdon is a Master’s student in Dr. John M. Clark’s toxicology lab at the University of Massachusetts at Amherst in the Animal Biotechnology and Biomedical Sciences program. She received her Bachelor’s degree in Animal Science with a pre-veterinary concentration from UMass-Amherst in 2005. She plans to graduate in the spring of 2008 and obtain a research and development position in
the pharmaceutical industry. Hilliary’s current research is focused on the mechanism of action of binary mixtures of pyrethroids at the presynaptic nerve terminal of rat brain and the contribution that individual voltage-sensitive ion channels play in the observed neurotoxicity.


Second Place – Keri L. Henderson. Fate of sulfamethazine in surface water microcosms. K. L. Henderson, T. B. Moorman, J. R.Coats; Iowa State University, Ames, IA.

Keri is currently a Ph.D candidate in Toxicology at Iowa State University, finishing a dissertation under the direction of Dr. Joel Coats (Dept. of Entomology) and Dr. Tom Moorman (USDA-ARS National Soil Tilth Laboratory, co-major advisor). Her research centers on the potential environmental significance of current livestock production practices, specifically, focusing on the transport and degradation of veterinary pharmaceuticals in manure-soil and surface water systems, including the assessment of potential biological impacts of antibiotics using relevant invertebrate and microbial models. She was awarded a STAR Graduate Research Fellowship from the U.S. Environmental Protection Agency to fund her Ph.D. studies. Her dissertation research objectives involve assessing the fate of veterinary antibiotics in soil columns and aquatic microcosms, developing models for assessing bioavailability in soil and water, and evaluating the potential impact of antibiotics on microbial communities. She completed her M.S. in Toxicology from Iowa State University in August 2004. The focus of her M.S. was the environmental fate of herbicides in grass phytoremediation soil systems, and involved the assessment of herbicide degradation in soil and plant tissues. She holds a B.A. from Wartburg College, with majors in Biology and Education. In her spare time, Keri enjoys spending time with her daughter, camping, hiking, and trying new recipes. She also enjoys participating on the Board for the Ozark-Prairie Region of the Society of Environmental Toxicology and Chemistry (SETAC), and as a symposium organizer and student representative in the Agrochemicals Division of ACS. She looks forward to seeing all of you at future ACS meetings.

Third Place (tie) – Deok Ho Kwon. Molecular cloning of sodium channel and

resistance in Tetranychus urticae. D. H. Kwon, B. R. Choi, S. W. Lee, H. M. Park,
J. M. Clark, S. Lee; University of Massachusetts, Amherst, MA.

Deok Ho Kwon received his BS in agricultural biology in 2001 fromAndong National University and his MS in applied entomology in 2003 from Seoul National University. His research area is the rapid diagnostics of insecticide resistance level to the field population by the molecular biological and biochemical approaches for the effective
management of resistant population. He has established two point mutation allele frequency determination methods associated with insecticide resistance by rtPASA and quantitative sequencing from Plutella xylostella and Tetranychus urticae. Recently he discovered L1022V and A1374D mutations from the resistant T. urticae. He will carry out the analysis the function of these mutations against to the fenpropathrin utilizing an electrophysiological approach.

Third Place (tie) – Dhana Raj Boina. Toxicity and mode of action of the anion transporter blockers against the European corn borer. D. R. Boina, J. R. Bloomquist; Virginia Tech University, Blacksburg, VA.

Dhana Raj Boina is an international student from India. He came to the USA in 2002 to pursue his masters program in entomology at Kansas State University, Manhattan, KS. He has
won a several awards recognizing of his research. The most notable were a first prize in poster competition at the 51st national annual meeting of the Entomological Society of America in 2003 and a David and Lillian Francis memorial fellowship from Virginia Tech in 2006. Currently, he is adoctoral student working under the supervision of Dr. Jeffrey R. Bloomquist at Virginia Polytechnic Institute and State University, Blacksburg, VA. His dissertation research involves determining the toxicity and site/mode of action of anion transporter (AT) blockers against selected insect and nematode species using toxicological, electrophysiological and molecular techniques. AT blockers are known for inhibiting anion transporters such as voltage-gated chloride channels and chloride/bicarbonate exchangers in biological systems. A major goal of his research is to find new pesticidal molecules targeting novel sites in insects and nematodes for effective control of crop pests.

Congratulations to all our winners!
