Investigation of Two Insect Species for Control of Eurasian Watermilfoil
This report presents the results of the evaluation of two species of insects for the biological control of Eurasian watermilfoil (Myriophyllum spicatum L.). One of the species is a native weevil, Litodactylus leucogaster (Marsh.), which attacks the flower spikes, and the other is an accidentally introduced European moth, Acentria nivea (Oliver), whose larvae feed on the leaves and stems. The biology of L. leucogaster was studied in detail and host-specificity tests were conducted with adults and larvae.

Invasiveness Ranking System for Non-native Plants of Alaska
Describes a ranking system used to evaluate the potential invasiveness and impacts of 113 non-native plants to natural areas in Alaska. Species are ranked by a series of questions in four broad categories: ecosystem impacts, biological attributes, distribution, and control measures. Also included is a climate screening procedure to evaluate the potential for establishment in three ecogeographic regions of Alaska [Juneau, Fairbanks, Nome].
