BERENBAUM Department of Entomology, University of Illinois at Urbana-Champaign, 320 Morrill Hall, 505 S Goodwin Ave., Urbana, IL 61801 Environ. Entomol. 35(3): 607Ð615 (2006) ABSTRACT Conium maculatum L. (Apiaceae), or poison hemlock, is an invasive plant native to Europe that has become extensively naturalized throughout North America. This species contains piperidine alkaloids, including coniine and ␥-coniceine, that are highly toxic to vertebrates. C. maculatum was relatively free from herbivores in North America until the accidental introduction 30 yr ago of its monophagous European associate Agonopterix alstroemeriana (Clerck) (Lepidoptera: Oecophoridae). At present, A. alstroemeriana is widespread across the United States, and in some areas, such as the Northwest, can inßict substantial damage on its host plant, leading to desiccation and death. A. alstroemeriana has been used in recent years for the biological control of C. maculatum, although its use has been limited by the availability of larvae, which are Þeld-collected from early to mid-spring, and by the lack of available information about its life history and feeding habits. Here we describe a laboratory-rearing protocol incorporating a simulated winter to induce diapause and a semideÞned artiÞcial diet that allows the production of multiple generations per year and enabled us to determine the number and duration of A. -

All symptoms resolved within 24 hours of the inges- tion and she was discharged on day 2. The ED staff identified the plant as “poison hemlock” by means of an internet search. Poison hemlock (Conium maculatum) is an invasive herb in the carrot (Apiaceae) family. It can be found along roads, ditches, fences, streams, or anywhere with adequate moisture, throughout the U.S. Other common names for the plant are deadly hemlock, poison parsley, and winter fern. The poison hemlock plant grows to 4-10 feet tall and has a smooth, non-hairy, hollow stem with red-purple streaks. These blotches are called the “blood of Socrates” as poison hemlock was reportedly used to kill Socrates. The small white flowers grow in -4 6 inch wide “umbels” or clusters that resemble um- brellas. The leaves have a lacy, fern-like appearance.

Poison Hemlock (Conium Maculatum)
Weed Identification and Control Sheet: www.goodoak.com/weeds WI NR-40: Poison Hemlock (Conium maculatum) Prohibited DESCRIPTION: Poison hemlock was introduced to North America in the 1800s from Europe, western Asia, and North Africa as a garden plant for its attractive ferny foliage. This member of the carrot family is toxic to most animals and eating even a small fragment can kill a human. All parts of the plant are poisonous, but the root is especially toxic. This biennial or short-lived perennial prefers moist soils and full to partial sun. In such habitats it forms dense stands that out-compete natives for space and light. It spreads extensively by seed, producing more than 30,000 seeds per plant and remains viable in the soil for several years. These seeds are released from late summer into winter and are dispersed by water, wind, and attaching itself to fabric and fur. Since it is a new invader you should report any sightings of this plant to the DNR (see: http://dnr. wi.gov/topic/Invasives/report.html). IDENTIFICATION: In the first year poison hemlock produces large rosette leaves; the second year a tall stem emerges and the plant flowers. Poison hemlock grows 3 to 10 ft. tall with a ribbed hol- low stem with purple spots. This species has a umbel shape flower cluster with small white flowers that have petals and blooms June to July. Leaves are opposite and triangular in outline and have a fern like shape. Leaves when crushed release a foul odor. Poison hemlock can be confused with water hemlock, a rare native found only in good-quality wetlands, but the leaves can help distinguish these two species. -
Poison Hemlock (Conium Maculatum)
KING COUNTY NOXIOUS WEED ALERT Class B Noxious Weed: Poison Hemlock Control Required on Conium maculatum Parsley Family Public Lands and Roads Identification Tips • Tall biennial, reaching 8 to 10 feet the second year • Bright green, fernlike leaves with strong musty smell • First year plants form low clumps of lacy leaves with reddish spots on stems • Second year stems are stout, hollow, hairless, ribbed, with reddish or purple spotting/streaking • Flowering plants covered with numerous small, umbrella-shaped clusters of tiny white flowers that have five petals • Seeds form in green, ridged capsules that eventually turn brown Poison-hemlock has bright green, fern- like leaves with a musty smell. Biology Reproduces by seed. First year grows into a rosette; second year, develops tall stems and flowers. Rapid growth from March to May, flowers in late spring. Up to 40,000 seeds per plant are produced. Seeds fall near the plant and are moved by erosion, animals, rain and human activity. Seeds viable up to 6 years and germinate throughout the growing season; do not require a dormant period. Impacts Acutely toxic to people, livestock, wildlife; causes death by Thick, hairless stems have reddish- respiratory paralysis after ingestion. Aggressive growth crowds out purple spots or streaks. desirable vegetation. Early spring growth makes it more likely to be eaten by animals when there is limited forage available. Can be mistaken for a carrot when small. Distribution Eurasian species, widely found in North America. Widespread in King County; found along roadsides, riparian areas, ravines, fields, ditches and un-managed yards and vacant lots. -

A WEED REPORT from the book Weed Control in Natural Areas in the Western United States This WEED REPORT does not constitute a formal recommendation. When using herbicides always read the label, and when in doubt consult your farm advisor or county agent. This WEED REPORT is an excerpt from the book Weed Control in Natural Areas in the Western United States and is available wholesale through the UC Weed Research & Information Center (wric.ucdavis.edu) or retail through the Western Society of Weed Science (wsweedscience.org) or the California Invasive Species Council (cal-ipc.org). Conium maculatum L. Poison-hemlock Family: Apiaceae Range: Throughout the contiguous U.S., including every western state. Habitat: Moist soil along hedgerows, along the banks of streams and rivers, roadsides and wastelands, woodlands, meadows, and pastures. Origin: Native to Europe. Impact: Produces piperidine alkaloids which are highly toxic to humans and animals. Domestic animals such as swine, cattle, goats, horses, and sheep can be poisoned by the toxin coniine after ingesting any portion of the plant. Poison-hemlock is the most toxic to cattle. Symptoms can include vomiting, nausea, trembling, rapid respiration, joint and movement problems, slow, weak and rapid pulse, increased salivation and urination, convulsions, paralysis, coma, and death from respiratory paralysis. Ingestion during fetal development can result in severe birth defects. States listed as Noxious Weed: Colorado, Idaho, Nevada, New Mexico, Oregon, Utah, Washington California Invasive Plant Council (Cal-IPC) Inventory: Moderate Invasiveness Poison-hemlock is a tall branching biennial to 4 to 6 ft tall. The stem is erect, hollow, smooth, bright green with a distinctive mottled appearance and irregular purple splotches.
