  • 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

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.

Maria di Galeria (Rome), Italy Received: August 5, 2010 Accepted: November 3, 2010 SUMMARY The Scotch thistle, Onopordum acanthium (Asteraceae) has the Eurasian origin and represents an invasive weed in the USA and Australia. It is a serious problem in pastures, along roadsides, rangeland, etc. The weed is very common in Bulgaria and in 2009-2010 several sites with large populations of O. acanthium have been located. The weekly sur- veys of some of the sites, mainly in the region of Plovdiv, revealed a significant diver- sity of phytophagous insect species, some of which had very high population density. More than 30 species have already been identified and observations on the phenolo- gy and biology of some of them have been conducted. For some of the species, such as endophagous Larinus latus, Lixus cardui, Eublemma amoena, Trichosirocalus briesei, or ectophagous Cassida rubiginosa etc. found during our surveys, there are reports in the lit- erature describing them as having been already introduced as successful biocontrol agents in Australia. Endophagous species like lepidopteran Myelois circumvoluta and Pyroderces argyrogrammos which feed on the stems and the head, and the tephritid flies Tephritis pos- tica and Chaetostomella cylindrica which feed on the capitula, seem quite destructive for the weed, but need to be further studied regarding host specificity.

  • An Investigation to the Subfamily of Lixinae from Khorasan Junoubi and Razavi Provinces of Iran (Coleoptera: Curculionidae)
    _____________Mun. Ent. Zool. Vol. 5, No. 2, June 2010__________ 559 AN INVESTIGATION TO THE SUBFAMILY OF LIXINAE FROM KHORASAN JUNOUBI AND RAZAVI PROVINCES OF IRAN (COLEOPTERA: CURCULIONIDAE) Mehdi Modarres Awal* and Fahimeh Hossein Pour* * Department of Plant Protection, College of Agriculture, Ferdowsi University of Mashhad, IRAN. Email: [email protected] [Moderres Awal, M. & Hossein Pour, F. 2010. An investigation to the subfamily Lixinae from Khorasan Junoubi and Razavi provinces of Iran (Coleoptera: Curculionidae). Munis Entomology & Zoology, 5 (2): 559-562] ABSTRACT: During 2006-2008 subfamily of Lixinae was surveyed in North eastern and east provinces of Iran. In total, 27 species belonging to 15 genera were determined. Among them three species including of Larinus sericatus (Boheman, 1834), Bangasternus provincialis (Fairmaire, 1863) and Conorhynchus verucundus (Faust, 1883) are new record for Iran fauna. KEY WORDS: Curculionidae, Lixinae, Khorasan, Iran, new records. Khorasan is the widest region in Iran (with total area 315686 Km²) that is divided in three provinces concern Khorasan Junoubi, Razavi and Shomali. This area surrounded by Turkmenistan and Afghanistan, also linked with four provinces include Kerman, Balouchestan, Yazd and Semnan. Curculionidae is currently the largest family of insects in the world with at least 3600 genera and 41000 species. Lixinae is a subfamily of true weevils, included three tribes Cleonini, Lixini and Rhinocyllini. Main characteristic of this subfamily include tarsal claws are fused at the base, and labial palps are short and telescoping. In addition, their body is elongated shape as for some other weevils, tibiae bear and uncus on its distal end and the rostrum is forwardly directed (Boothe et al., 1990).

  • Biological Control
    California Exotic Pest Plant Council 1996 Symposium Proceedings Yellow Starthistle Control Methods: Biological Control Michael Pitcairn California Department of Food and Agriculture Biological Control Program 3288 Meadowview Road, Sacramento, CA 95832 Introduction Classical biological control of weeds works by reuniting an exotic weed species with its natural invertebrate or microbial enemies. This involves searching for and identifying the natural enemies that attack the weed in its area of origin, followed by extensive safety and host specificity testing of those natural enemies, and finally the release of those deemed safe on sites here in the United States. For yellow starthistle, Centaurea solstitialis, the area of origin is believed to be 'southern Europe (France, Italy, and Greece) and Central Asia (Turkey, Armenia, and Iran) (Maddox 1981). Before a natural enemy is released in the United States, its host specificity is examined in quarantine for safety. Only those natural enemies that have a high degree of host specificity will be introduced into California. Thus, not all of the 42 or more species of insects and diseases that attack yellow starthistle in Europe (Clement 1990) will be released in North America, only those that attack yellow starthistle and possibly one or two other species in the genus Centaurea. Safety is evaluated through host specificity testing in which a series of plants are exposed to potential biological control agents and examined for feeding, oviposition, larval development and adult emergence. Host specificity testing follows standard protocols that assume that a plant's natural enemy is most likely to feed on close relatives to the target host, less likely to feed on distant relatives, and unlikely to feed on unrelated hosts.
