| Abstract: | Fauna associated with Eurasian watermilfoil (Myriophyllum spicatum L.) were collected and identified from 71 collections in 11 states. Sixty-four insect taxa were identified, of which damselfly nymphs were most frequently encountered, being found in two thirds of the collections. Midge larvae, when present, were the predominant component of collections, both in number of individuals and number of species. Larvae of aquatic moths fed voraciously on Eurasian watermilfoil and produced the most severe damage of any group. Three species of caddisflies were found to be probable or possible feeders on Eurasian watermilfoil. An aphid and three weevil species were found to feed on emersed flower spikes, but their direct impacts were thought to be minimal. None of the insects identified in this study appeared to be promising candidates as biological agents for the control of Eurasian watermilfoil. |
