Biological control has long been used against invasive plants and, less often, invasive insects, in forests, aquatic systems, grasslands, coastal areas, riparian areas, islands, and other biomes or habitats of conservation concern. Historically, motivation for such efforts has shifted gradually away from economic interests toward ecological protection for its own sake. Future projects of this type will require better integration of biological control into conservation practice, a better understanding by societies of the reasons for such work and its possible risks and benefits, as well as continued, consistent public funding. Examples of successful projects in high-value conservations areas (Everglades, Galápagos, oceanic islands, wetlands, forests) are discussed, and future challenges and caveats mentioned.

    Biological Control of Two Ageratina Species (Asteraceae: Eupatorieae) in South Africa

    Biological control of two Ageratina species (Asteraceae: Eupatorieae) in South Africa F. Heystek1*, A.R. Wood2, S. Neser1 & Y. Kistensamy1 1Agricultural Research Council-Plant Protection Research Institute, Private Bag X134, Queenswood, 0121 South Africa 2Agricultural Research Council-Plant Protection Research Institute, Private Bag X5017, Stellenbosch, 7599 South Africa Ageratina adenophora (Spreng.) R.M.King & H.Rob. and Ageratina riparia (Regel) R.M.King & H.Rob. (Asteraceae: Eupatorieae), originally from Mexico, are invasive in many countries. These plants produce thousands of wind- and water-dispersed seeds which enable them to spread rapidly and invade stream banks and moist habitats in areas with high rainfall. Two biological control agents, a shoot-galling fly, Procecidochares utilis Stone (Diptera: Tephri- tidae), and a leaf-spot fungus, Passalora ageratinae Crous & A.R. Wood (Mycosphaerellales: Mycosphaerellaceae), were introduced against A. adenophora in South Africa in 1984 and 1987, respectively. Both established but their impact is considered insufficient. Exploratory trips to Mexico between 2007 and 2009 to search for additional agents on A. adenophora produced a gregarious leaf-feeding moth, Lophoceramica sp. (Lepidoptera: Noctuidae), a stem-boring moth, probably Eugnosta medioxima (Razowski) (Lepidoptera: Tortricidae), a leaf-mining beetle, Pentispa fairmairei (Chapuis) (Coleoptera: Chrysomelidae: Cassidinae), and a leaf-rust, Baeodromus eupatorii (Arthur) Arthur (Pucciniales: Pucciniosiraceae) all of which have been subjected to preliminary investigations. Following its success in Hawaii, the white smut fungus, Entyloma ageratinae R.W. Barreto & H.C. Evans (Entylomatales: Entylomataceae), was introduced in 1989 to South Africa against A. riparia. Its impact has not been evaluated since its establishment in 1990 in South Africa. By 2009, however, A.

Watson) Britten and Rosel, organ-pipe (.Stenocereus thurberi Buxb.), and senita fLophocereus schottii (Engelm.) Britten and Rosel (all Cactaceae), endemic to the Sonoran Desert of North America. A total of 9380 arthropods belonging to 34 species, 23 families, 10 orders, and 2 classes were col- lected in 36 samples. Arthropod communities differed in composition among host cacti, as well as between seasons. These differences may be a function of variation in host characteristics, such as chemical composition and abiotic factors, such as water content or temperature. Castrezana S, Markow TA. 2001.

Ikke alle eksem- plarer er så stærkt tegnet som ovenstående. Agapeta hamana (L.) Larven lever overvintrende i i rødderne af forskellige tidsler (Carduus, Cirsium mv.). Udbredt i Europa op til Mellemsverige og Finland. Almindelig. Agapeta largana (Rebel) 4270 16-23 mm. Imago er på vingerne i solens sidste stråler fra sidst i juni gennem juli. Lokalt ikke sjælden på enge. Præimaginale stadier er ukendte. Kendt fra Grækenland, Rumænien, Ungarn, det vestlige Østrig og jeg har selv fundet den flere steder i det sydøstlige Frankrig. Agapeta zoegana (L.) 4271 15-24 mm. Imago flyver i de sidste lyse timer og kommer fint til lys i juli-august. Agapeta zoegana (L.) Larven lever overvintrende i rødderne af Blåhat (Knautia) og Knopurt (Centaurea). Den forpupper sig i rødderne. Agapeta zoegana (L.) Ind i mellem dukker eksemplarer op som er formørket i den yderste tredjedel. Disse eksemparer er gerne mindre end normalt. Agapeta zoegana (L.) I Danmark er der ikke mange findesteder i Jylland og arten mangler helt vest for israndslinjen. I det øvrige land er den ikke sjælden, men sjældent talrig. Nordgrænsen går gennem det sydligste Norge, mellemste Sverige og sydlige Finland. Arten når til Ural og Lilleasien. Eugnosta lathoniana (Hb.) 4279 21-27 mm. Imago flyver sidst på dagen fra midt i maj til sidst i juni. Præimaginale stadier er ukendte. Udbredt i det meste af Sydeuropa, mod nord til Tyskland, men herfra kendes ingen konkrete fund.

Day 1 Monday 29th January UK to Quito People arrived in Quito via Amsterdam with KLM or via Madrid with Iberia, while Tony came separately from the USA. Everyone was met at the airport and taken to the Hotel Vieja Cuba; those who were awake enough went out to eat before a good night’s rest. Day 2 Tuesday 30th January Quito. Weather: Hot and mostly sunny. The early risers saw the first few birds of the trip outside the hotel: Rufous- collared Sparrow, Great Thrush and Eared Doves. After breakfast, an excellent guide took us on a bus and walking tour of Quito’s old town. This started with the Basilica del Voto Nacional, where everyone marvelled at the “grotesques” of native Ecuadorian animals such as frigatebirds, iguanas and tortoises.

    Controlling Invasion of the Exotic Shrub (Mimosa Pigra) in Tropical Australian Wetlands

    Controlling invasion of the exotic shrub (Mimosa pigra) in tropical Australian wetlands Michelle Marko Introduction to exotics in Australia Exotics have been introduced to Australia since the time of European settlement, beginning in the 1800s. Whether deliberately or accidentally introduced, some species such as feral cats (Felis catus), the cane toad (Bufo marinus), athel trees (Tamarix aphyllabitou) and the bitou bush (Chrysanthemoides monilifera), have wrought devastation. The majority of exotics have little impact on the natural ecosystem, but those that do (between 2-40 %) are aggressive invaders that can successfully compete for niches previously occupied by native species. Many exotics not currently problematic have the potential to cause serious damage in the future (Hobbs and Humphries 1995). These exotics negatively modify the richness and abundance of other species and therefore alter the function of the natural ecosystems (Storrs and Lonsdale 1995). In Australia, about 15% of the overall vascular flora are naturalized alien species, which is estimated to be 15,000-20,000 species (Environment Australia 1998). The Northern Territory, with around 4-5 % weeds, has the lowest percentage of any state or territory in Australia. However, in the Northern Territory, Sida sp., salvinia (Salvinia molesta), Hyptis suaveolens, water hyacinth (Eichhornia crassipes), and giant sensitive plant (Mimosa pigra) are considered major threats (CSIRO 1997). Mimosa pigra, in particular, is considered one of Australia's worst weeds of conservation. In this paper, I will discuss methods to control Mimosa pigra and some areas of future research. Invasiveness of Mimosa pigra Mimosa pigra L. (Mimosaceae) poses a tremendous threat to agriculture, the conservation of wetlands and land use practices of the Aboriginal people of Australia (Braithwaite et al.
