Invasive species are not welcome Flower Show participants…. Invasive plant species are everywhere. As gardeners and stewards of our land we need to know, recognize and remove these threats from our yards and public lands. Below is a list of the Invasive Species listed for the state of Massachusetts.
Euonymus alatus
Massachusetts Invasive Plant List
ALB Found In Massachusetts from DCR August Citizen Forester
As of Friday August 1, 2008 Asian Longhorned Beetle Anoplophora glabripennis was officially added to the growing list of invasive pests in Massachusetts. Residents of the Greendale section of Worcester reported finding Asian Longhorned Beetle (ALB) in their neighborhood. Click on ALB Regulated Area for a map of the quarantine area. Nursery stock, wood and plant debris from tree species affected by ALB are prohibited from being transported out of the quarantine area. Preferred Host Tree Species: all Maples, Elm, Willow, Horse Chestnut, Poplars and Birch; other less preferred trees species include: Linden, London Plane, Mountain Ash, Hackberry and Mimosa. Description: adult ALB is .75” to 1.5” in body length, very long antenna with each segment alternating between black & white. Shiny black in color with crisp white spots on wing covers. Larvae are typical of round-headed borers and feed in vascular area before boring into sapwood & heartwood to pupate. Exit hole of adult beetle is a 3/8”-1/2” round hole.

Massachusetts Introduced Pests Outreach Project Scientific Name:Pyrrhalfa viburni Common Name:Viburnum Leaf Beetle This beetle is native to Europe and most likely came to North America on plants in the early 1900’s. It was first found in 1947 in Ontario, Canada and later discovered in New YorkState in 1996.Interestingly the beetle did not occur in very high numbers for many years; only late in the 1970’s it became a viable pest problem.In the eastern US, the beetle has spread to neighboring states, including Maine, New Hampshire, Vermont, New York and a small portion of Pennsylvania and Ohio. The viburnum leaf beetle only feeds on Viburnum species. V. denatum complex (arrowood viburnums) V. opulus (European cranberrybush viburnum) V. opulus var. americana (American cranberrybush viburnum) V. rafinesquianum (Rafinesque virburnum) These virburnum are the most susceptible to the viburnum leaf beetle. V. lantana (Wayfaringtree viburnum) V. lentago (Nannyberry viburnum) V. prunifoliu, (Blackhaw viburnum) V. sargentii (Sargent viburnum) These are somewhat susceptible to the viburnum leaf beetle and its’ damage. Key ID Features (Adults, Larvae and Eggs): Larvae hatch in late April and feed until mid-June when they pupate. Immature larvae are about 1mm long, greenish to off white and lack spots. Immature larvae are very difficult to see and are found on the underside of leaves. Mature larvae are 10-11mm (about ½ inch long) and are yellowish brown and have spots. Adults are brown, 4.5-9.5mm (about ¼ inch) in length and are difficult to see. Adults emerge in early July and feed until leaf drop. Egg ‘caps’ are 1-2mm in diameter, brownish-black in color and are arranged in
Have you Seen the Red Lily Beetle? The red lily beetle (Lilioceris Lilli), also known as the lily leaf beetle, is a native of Europe and was discovered in North America near Montreal in 1943. Its damage was limited to the Montreal area for decades, but recently it has spread to the south and west. Many gardeners believe it came with bulbs shipped from Europe. The beetles are strong fliers and excellent hiders. In 1992 they had spread into Ontario and the New EnglandStates, and in 2004 they were reported in the Portage la Prairie area in Manitoba. This last year there have been 15 different sites reported in Manitoba as well as the area around Calgary, Alberta. However, not all areas are yet infested and gardeners who are transplanting bulbs should be careful not to move these beetles to an uninfected area. The red lily beetle is an 8mm long bright red beetle with a black head and legs. The larvae have dirty orange-red bodies with black heads. The larvae usually cover themselves with their own slimy black excreta and could be mistaken for bird’s droppings. With adequate food they reach 8-10mm in length, at which stage they pupate in the soil. Both adults and larvae damage lilies primarily by defoliating them, but in heavy infestations the flowers seed capsules and stems will also be eaten. Although adult beetles have been found on other plant species, it is only the lilies and fritillaries which are true hosts on which eggs are laid and the larvae develop. In Canada no natural predator is known. Richard A. Casagrande, University of Rhode Island, Bugwood.org Control Gardeners can control small areas by handpicking adults and eggs. Insecticides which contain extracts from the Neem tree are also effective in killing larvae and repelling adults. Recent efforts to control the lily beetle have concentrated on biological control. The North American Lily Society has supported the scientific introduction of the biological control method using parasitoids (a moth which lays its eggs in the larvae) in the New England States over the last seven years. This study has been completed and declared a success. At present gardeners rely on chemicals or hand picking to control this pest, but the long period over which the adults are active (late April to October) can make this difficult. Adequate control in areas where the pest is abundant may require measures to be repeated during spring and summer. In some areas of Ontario and Quebec, gardeners have stopped growing lilies due to this beetle. We know that the problem will likely become more widespread, and while we can monitor our garden lilies there is concern for our wild prairie lilies (L. philadelphicum var. andinum). It is hoped that through a network of volunteers, the movement and activities of the red lily beetle can be monitored in Saskatchewan and thereby protect the wild prairie lily. The Saskatchewan Ministry of Environment has been made aware of this threat, and has indicated that if this invasive species is found necessary action will be taken as required. We need your help in monitoring this pest, which you can expect to see early in the spring. Protect your lily patches and if you spot this beautiful but deadly pest, please call Dolores Nelson, South Saskatchewan Lily Society at 306-586-3697.
