The weevil was first released in the United States for biological control of yellow starthistle, Centaurea solstitialis L. (Asteraceae: Cardueae), during Biological Control of Yellow Starthistle (Centaurea solstitialis) in the Salmon River Canyon of Idaho Jennifer L. Birdsall and George P. Markin* Yellow starthistle is an invasive, annual, spiny forb that, for the past 30 yr has been steadily advancing up the Salmon River Canyon in west central by: 4. 3 Chapter 1: Getting to Know Yellow Starthistle; 4 Chapter 2: Biology of Yellow Starthistle Biocontrol Agents; 5 Chapter 3: Elements of a Yellow Starthistle Biological Control Program. Program; 6 Glossary; 7 Selected References; 8 Appendices. Yellow starthistle (Centaurea solstitialis L) (YST) is an invasive weed native to the Mediterranean region with a geographical centre of diversity in Turkey. It is widely established in Chile, Australia, and western North by: 3.
Evaluating biological control of yellow starthistle (Centaurea solstitialis) in California: A GIS based supply–demand demographic model Andrew P. Gutierreza,*, Michael J. Pitcairnb, C.K. Ellisa, Nada Carruthersc, Reza Ghezelbasha a Division of Ecosystem Science and the Center of Biological Control, University of California, Berkeley, CA , USA b Biological Control Program, California. The biological control of yellow starthistle (Centaurea solstitialis) by four capitulum-feeding insects (weevils Bangasternus orientalis and Eustenopus villosus, and flies Urophora sirunaseva and Chaetorellia succinea), as affected by plant competition with annual grasses, is analyzed using a weather-driven, physiologically based, age-structured, simulation by: Yellow starthistle was probably introduced into the United States through contaminated alfalfa in the mid’s. BIOLOGY & SPREAD Spread of yellow starthistle is by seed and each seedhead can produce from 35 to approximately 80 seeds. Biological Control Four natural enemies of yellow starthistle have been imported from Europe and by were well established in California. These biological control agents include two weevils (Bangasternus orientalis and Eustenopus villosus) and two flies (Urophora sirunaseva and Chaetorellia succinea).
Yellow Starthistle Biology Wendy West University of California Cooperative Extension. Yellow Starthistle •Navite to Eurasai • Introduced in the ’s • Annual • Large plants can produce over , seeds Biological Control. Grazing. Grazing • Time the grazing to damage YST when it’s. The Hairy Weevil is having significant impact as a bio-control agent of yellow starthistle. Releases of adults are $ in late June - early July.
