A biological control program was implemented during the late 1970s in an attempt to manage infestations of rush skeletonweed and to limit its spread into new areas. Three agents, Cystiphora schmidti (Rübsaamen) (a gall midge), Aceria chondrillae (Canestrini) (a gall mite), and Puccinia chondrillina Bubak & Sydenham (a rust fungus) have been established in Idaho and other areas of the western United States. However these agents have provided only limited control of the weed. One additional agent, the root-feeding moth Bradyrrhoa gilveolella (Treitschke) (Lepidoptera, Pyralidae), was approved by the USDA-APHIS for release in the United States in 2002. Initial releases were made in southern Idaho in November 2002 and during the summers of 2003 through 2009 (excluding 2005). Releases were made using infested plants (the 2002 initial release) then utilizing first instar larvae and adults from greenhouse colonies. In total we released the moth at eight sites utilizing nine infested plants (est. -

Impact of Biological Control on Two Knapweed Species in British Columbia
Impact of Biological Control on Two Knapweed Research Report Species in British Columbia Don Gayton, FORREX & Val Miller, B.C. Ministry of Forests, Lands and Natural Resource Operations Abstract Diffuse and spotted knapweed ( Centaurea diffusa Lam and C. stoebe L.) are two closely re - lated invasives found in many parts of British Columbia’s Southern Interior, causing sub - stantial economic losses in rangelands. Beginning in 1970, the provincial government initiated a long-term biological control effort against the knapweeds, introducing 10 dif - ferent insect agents from 1970 to 1987. In an effort to evaluate the efficacy of the program, archival (1983–2008) data was amassed from 19 vegetation monitoring sites that contained knapweed. In 2010, these sites were relocated and re-monitored and cover values were an - alyzed. Diffuse knapweed showed significant declines at 14 of 15 sites; spotted knapweed declined at three of four sites. Possible alternative explanations for the decline are dis - cussed. Evidence strongly points to a suite of biocontrol agents (seed feeders and root feed - ers) as the primary drivers of knapweed decline in British Columbia’s Southern Interior. KEYWORDS : biological control; British Columbia; Centaurea ; knapweed; monitoring Introduction iffuse knapweed ( Centaurea diffusa Lam.) and spotted knapweed ( Centaurea stoebe L.) are two introduced, closely related invasive forbs. These species are most com - Dmon in the northwestern United States and in western Canada. Centaurea stoebe (also referred to as C. maculosa Lam. and C. biebersteinii DC) is particularly widespread, reported in 45 US states and all provinces of Canada (Marshall 2004; Zouhar 2001). The drought-tolerant C. diffusa has an altitudinal range of 150–900 m, whereas C. -
Biological Control of Yellow Starthistle
Biological Control of Yellow Starthistle Lincoln Smith, USDA-ARS-WRRC, 800 Buchanan St, Albany CA 94710 Joe Balciunas, USDA-ARS-WRRC, 800 Buchanan St, Albany CA 94710 Michael J. Pitcairn, California Dept. of Food and Agriculture, 3288 Meadowview Road, Sacramento, CA 95832 Yellow starthistle (Centaurea solstitialis L.) is an alien plant that probably originated from the eastern Mediterranean. It was first collected in California in 1869, and now infests 42% of the state’s townships. It interferes with land use such as grazing and recreation, displaces native species, and is toxic to horses (Sheley, et al. 1999 and papers cited therein). This weed is much less invasive in its land of origin. This is presumably because natural enemies, such as insects, plant diseases, animals or competing plants help to keep it under natural control. We are exploring for insects and pathogens that attack this plant. They are tested for host specificity to make sure they do not attack other plants. After evaluation and approval by state and federal agencies, these agents will be released to try to reestablish the natural control that occurs in the land of origin. So far, six species of insect biological control agents have been introduced to control yellow starthistle (Turner et al. 1995; Rees et al. 1996; Jette, et al. 1999). All six attack the seedheads. The most promising agent is the hairy weevil (Eustenopus villosus), which is well established in California and occurs in high densities, attacking 25 to 80% of seedheads. Adults damage young flower buds by feeding on them, and lay eggs on later-developing flower buds. -

Population Buildup and Combined Impact of Introduced Insects on Yellow Starthistle (Centaurea Solstitialis L.) in California

Spencer [ed.]. pp. 747-751 (2000) Population Buildup and Combined Impact of Introduced Insects on Yellow Starthistle (Centaurea solstitialis L.) in California MICHAEL J. PITCAIRN1, DALE. M. WOODS1, DONALD. B. JOLEY1, CHARLES E. TURNER2, and JOSEPH K. BALCIUNAS2 1California Department of Food and Agriculture, Biological Control Program, 3288 Meadowview Road, Sacramento, California 95832, USA 2United States Department of Agriculture, Agricultural Research Service, 800 Buchanan Street, Albany, California 94710, USA Abstract Seven exotic seed head insects have been introduced into the western United States for control of yellow starthistle. Six are established; three are widespread. Preliminary evaluations suggest that no one insect species will be able to reduce yellow starthistle abundance in California. Rather, a combination of the current, and possibly, future natu- ral enemies may be necessary. Studies were initiated in 1993 to evaluate the population buildup, combined impact, and interaction of all available biological control insects on yellow starthistle. Three field sites were established in different climatic regions where yellow starthistle is abundant. Four insects, Bangasternus orientalis, Urophora sirunase- va, Eustenopus villosus, and Larinus curtus, were released at each site in 1993 and 1994 and long-term monitoring was initiated. The accidentally-introduced insect, Chaetorellia succinea, was recovered in 1996-98 at these sites. Four years after the first releases, we have evidence that these biological control agents are having an impact on yellow starthistle seed production that may translate into a decline in mature plant populations.
