I am interested in factors affecting the behavior and reproduction of the plant parasitic nematode Heterodera glycines.  This nematode parasitizes the roots of the soy bean plant, damaging the plant and reducing crop yields. We are investigating the production of chemoattractants by the soy bean plant used by the nematode in locating an appropriate host.  We are also examining various chemical and environmental factors controlling the hatching of the encysted nematode eggs.
