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. -
Biology and Recent Developments in the Systematics of Phoma, a Complex Genus of Major Quarantine Significance Reviews, Critiques

Biology and recent developments in the systematics of Phoma, a complex genus of major quarantine significance. Fungal Diversity 31: 1-18. Species of the coelomycetous genus Phoma are ubiquitously present in the environment, and occupy numerous ecological niches. More than 220 species are currently recognised, but the actual number of taxa within this genus is probably much higher, as only a fraction of the thousands of species described in literature have been verified in vitro. For as long as the genus exists, identification has posed problems to taxonomists due to the asexual nature of most species, the high morphological variability in vivo, and the vague generic circumscription according to the Saccardoan system. In recent years the genus was revised in a series of papers by Gerhard Boerema and co-workers, using culturing techniques and morphological data. This resulted in an extensive handbook, the “Phoma Identification Manual” which was published in 2004. The present review discusses the taxonomic revision of Phoma and its teleomorphs, with a special focus on its molecular biology and papers published in the post-Boerema era. Key words: coelomycetes, Phoma, systematics, taxonomy. -
Revision of Western Palaearctic Species of the Oulema Melanopus Group, with Description of Two New Species from Europe (Coleoptera: Chrysomelidae: Criocerinae)

Five species of the Oulema melanopus group are recognized in the western Palaearctic Region: O. melanopus (Linnaeus, 1758), O. rufocyanea (Suffrian, 1847), O. duftschmidi (Redtenbacher, 1874), O. mauroi sp. nov. (nor- thern Italy), and O. verae sp. nov. (Spain and Portugal). The two new species are described and illustrated. The nomenclature of the group is discussed in detail. Oulema rufocyanea is proved to be a validly described species different to O. duftschmidi. To fi x the nomenclatural stability of the whole group and avoid sub- sequent misintepretations, neotypes are designated for Crioceris melanopoda O. F. Müller, 1776; Crioceris hordei Geoffroy, 1785; and Lema cyanella var. atrata Waltl, 1835 (all conspecifi c with O. melanopus). The primary type specimens or their photographs were examined if they exist. The spelling Oulema melanopus is fi xed as correct and explained. Variation in the cytochrome c oxidase (cox1) gene across specimens of all the species has been analysed. All species in the group had extremely similar haplotypes, with interspecifi c sequence similarities between 90.5–99.5 %, compared to intraspecifi c sequence similarities between 91.6–100 %. -

Abstract The two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is one of the most polyphagous herbivores feeding on cell contents of over 1100 plant species including more than 150 crops. However, despite its important pest status and a growing understanding of the molecular basis of its interactions with plant hosts, knowledge of the way mites interface with the plant while feeding and the plant damage directly inflicted by mites is lacking. Likewise, while the use of the reverse genetic tools in plants facilitated our understanding of the establishment of defense mechanisms against spider mite herbivory, such tools are lacking for spider mite, preventing the expansion of functional analysis to both sides of the interacting organisms. -
Phytomyza Vitalbae, Phoma Clematidina, and Insect-Plant
Phytomyza vitalbae, Phoma clematidina, and insect–plant pathogen interactions in the biological control of weeds R.L. Hill,1 S.V. Fowler,2 R. Wittenberg,3 J. Barton,2,5 S. Casonato,2 A.H. Gourlay4 and C. Winks2 Summary Field observations suggested that the introduced agromyzid fly Phytomyza vitalbae facilitated the performance of the coelomycete fungal pathogen Phoma clematidina introduced to control Clematis vitalba in New Zealand. However, when this was tested in a manipulative experiment, the observed effects could not be reproduced. Conidia did not survive well when sprayed onto flies, flies did not easily transmit the fungus to C. vitalba leaves, and the incidence of infection spots was not related to the density of feeding punctures in leaves. Although no synergistic effects were demonstrated in this case, insect–pathogen interactions, especially those mediated through the host plant, are important to many facets of biological control practice. This is discussed with reference to recent literature. Keywords: Clematis vitalba, insect–plant pathogen interactions, Phoma clematidina, Phytomyza vitalbae, tripartite interactions. Introduction Hatcher & Paul (2001) have succinctly reviewed the field of plant pathogen–herbivore interactions. Simple, Biological control of weeds is based on the sure knowl- direct interactions between plant pathogens and insects edge that both pathogens and herbivores can influence (such as mycophagy and disease transmission) are well the fitness of plants and depress plant populations understood (Agrios 1980), as are the direct effects of (McFadyen 1998). We seek suites of control agents that insects and plant pathogens on plant performance. Very have combined effects that are greater than those of the few fungi are dependent on insects for the transmission agents acting alone (Harris 1984). -

Jejich růst je ovlivňován i saprotrofními houbami, které s nimi nemusí být v přímém kontaktu, ale mít příznivý vliv na rostliny díky produkci hormonů, kompetiční eliminaci „škodlivých“ organismů a dekompoziční aktivitě, vedoucí k tvorbě minerálních látek nebo uvolňování organických živin. Nakonec i po odumření houbových těl dojde k obohacení půdy o živiny – toho je využíváno i v přípravě některých hnojiv (Biosol obsahuje zbytkovou biomasu Penicillium chrysogenum z výroby penicilínu). Zásadní vliv mají ale symbiotické vztahy v rhizosféře, a to především s bakteriemi, aktinomycety a mykorhizními houbami. Přínosem mykorhizní symbiózy je kromě přímé výměny živin (využití organických zdrojů dusíku => nižší potřeba užívání hnojiv) též stimulace rozvoje dalších složek rhizosférní mikrobioty a jejich metabolické aktivity (projevující se především v produkci enzymů). Mimoto má růst mykorhizních hub v půdě význam pro její stabilizaci – nejde jen o mechanické zpevnění půdy, ale také o eliminaci eroze a vymývání živin. -
