The distribution of a potential new forest pest, Monsoma pulveratum (Hymenoptera: Tenthredinidae), in the Pacific Northwest states. Northwest Science. 86(4):342-345. Interpretive Summary: The caterpillar-like larvae of sawflies are all plant feeders and can cause extensive damage in forests, ornamentals, and agricultural crops. A species that feeds on alder was accidentally introduced into western Canada and Alaska and has caused widespread damage. A survey was undertaken to detect the presence of this pest in the Pacific Northwest. Results show that it is widespread in Washington and Oregon, and the species is reported from the Pacific Northwest for the first time. This will be of interest to state and federal forest service personnel in case damage to alder is noted in this region. Technical Abstract: An adventive alder-feeding sawfly, Monsoma pulveratum (Retzius), is reported from Oregon and Washington for the first time. Survey methods and distribution of the sawfly in these states is given. |
