Weevil Attractants Released by Eurasian Watermilfoil

Scientists will extend their research on the ability of a water- soluble compound released by Eurasian watermilfoil to attract a  weevil that helps to control this invasive plant.  This attractant,  possibly coupled with the synergistic action of other natural  products, could help ecologists, natural resource managers, and  agencies throughout North America manage invading populations of  this plant. Objectives: To determine the production and distribution of natural  products from Eurasian watermilfoil (Myriophyllum spicatum) that act  as host plant attractants to the weevil, Euhrychiopsis lecontei.   Environmental variables that might affect levels of attractant  production were to be determined under controlled conditions.   To determine the performance of the milfoil weevil on the exotic  Eurasian milfoil as compared to its native host plant, northern  milfoil (M. sibiricum), by correlating weevil potential fecundity  with plant chemistry.
