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. -

The native resident fauna of these islands consists of 42 species of which 21 (50%) are endemic, in 27 genera, of which 3 (11%) are endemic, in 12 families. The endemic fauna is characterised by brachyptery (66%), body size under 10 mm (72%) and concealed, or strictly ground- dwelling larval life. All species can be related to mainland forms; there is a distinctive pre-Pleistocene element as well as some instances of possible Pleistocene introductions, as suggested by the presence of pairs of species, one member of which is endemic but fully winged. A graph and tables are given showing the composition of the fauna, its distribution, habits, and presumed derivations. Host plants or host niches are discussed. An additional 7 species are considered to be non-resident waifs. The taxonomic part includes keys to families (applicable only to the subantarctic fauna), and to genera and species. -

Self-fertilization provides an advantage 28 in the short-term as individuals do not require a mate to reproduce, but self-fertilization is also 29 associated with both decreased genetic diversity and accumulation of weakly deleterious mutations, 30 which could, however, be alleviated in polyploid selfers. -

Summary TEPPNER H. 2003. The heterodiaspory of Capsella bursa-pastoris {Brassicaceae). - Phyton (Horn, Austria) 43 (2): 381-391, 2 figures. - English with German summary. In Capsella bursa-pastoris (L.) MEDIK. two kinds of diaspores are formed: 1) the valves of the silicle containing an apical seed (i.e. the uppermost seed of each locule), which are therefore one-seeded mericarps and 2) the true (naked) seeds. Finally, of the fallen valves c. 70 % contained the apical seed; these can be easily dispersed by water and wind. Terms for heteromorphic diaspores are briefly discussed. As regards to terminology, it is proposed to restrict the term heterodiaspory, in the sense of the definition of MÜLLER-SCHNEIDER & LHOTSKÄ 1972: 408, for such cases with diaspores of different levels of morphological organisation on one individual. As an encom- passing term for heterocarpy, heteromericarpy, heterospermy, heterodiaspory etc. the older term polydiaspory (MÜLLER 1955:16) can be used. Zusammenfassung TEPPNER H. 2003.

Phytochemical & Biological Evaluation of Cascabela Thevetia with Special
. Presented by: Biman Bhuyan Assistant Professor Department of Pharmaceutical Sciences Dibrugarh University Dibrugarh-786004, Assam, India Email ID:[email protected] Presented at: XIXth International Congress "Phytopharm 2015“ New Phytotherapeutics – Developments, Requirements and Success for Patients with Rational Phytotherapy. (Institute of Pharmacy, University of Bonn; July 21-24, 2015 ) . Diabetes mellitus is chronic disorder of carbohydrate, protein and fat metabolism resulting from insulin deficiency and abnormality in the use of insulin. Due to several problems with available conventional therapies, alternative approaches become essential to treat diabetes. Plant based medicine has become one of the most promising alternative strategy for treatment of diabetes. In this study the bark of Cascabela thevetia L. was selected for evaluation of antidiabetic activity based on its traditional use in Assam. T. Miyagawa et al. (J. Nat. Prod., 2009) in his article “Cardenolide Glycosides of Thevetia peruviana and Triterpenoid Saponins of Sapindus emarginatus as TRAIL Resistance-Overcoming Compounds” reported that cardenolide glycosides isolated from Thevetia peruviana (Cascabela thevetia) have significant reversal effect on TRAIL resistance in human gastric adrenocarcinoma cells. M.H. Khan et al. (Indian J Tradit Know., 2010) in his article “Antidiabetic plants used in Thoubal district of Manipur, North-East India” reported that bark of the plant is used by Meitei community for treatment of diabetes. V. Bandara et al. (Toxicon, 2010) in his article “A review of the natural history, toxinology, diagnosis and clinical management of Nerium oleander (common oleander) and Thevetia peruviana (yellow oleander) poisoning” reported the cardiac glycosides related toxicity and their clinical management in emergency.

Chromosome Numbers in Compositae, XII: Heliantheae
SMITHSONIAN CONTRIBUTIONS TO BOTANY 0 NCTMBER 52 Chromosome Numbers in Compositae, XII: Heliantheae Harold Robinson, A. Michael Powell, Robert M. King, andJames F. Weedin SMITHSONIAN INSTITUTION PRESS City of Washington 1981 ABSTRACT Robinson, Harold, A. Michael Powell, Robert M. King, and James F. Weedin. Chromosome Numbers in Compositae, XII: Heliantheae. Smithsonian Contri- butions to Botany, number 52, 28 pages, 3 tables, 1981.-Chromosome reports are provided for 145 populations, including first reports for 33 species and three genera, Garcilassa, Riencourtia, and Helianthopsis. Chromosome numbers are arranged according to Robinson’s recently broadened concept of the Heliantheae, with citations for 212 of the ca. 265 genera and 32 of the 35 subtribes. Diverse elements, including the Ambrosieae, typical Heliantheae, most Helenieae, the Tegeteae, and genera such as Arnica from the Senecioneae, are seen to share a specialized cytological history involving polyploid ancestry. The authors disagree with one another regarding the point at which such polyploidy occurred and on whether subtribes lacking higher numbers, such as the Galinsoginae, share the polyploid ancestry. Numerous examples of aneuploid decrease, secondary polyploidy, and some secondary aneuploid decreases are cited. The Marshalliinae are considered remote from other subtribes and close to the Inuleae. Evidence from related tribes favors an ultimate base of X = 10 for the Heliantheae and at least the subfamily As teroideae.

Diffuse Coevolution Between Two Epicephala Species (Gracillariidae) and Two Breynia Species (Phyllanthaceae)
Diffuse Coevolution between Two Epicephala Species (Gracillariidae) and Two Breynia Species (Phyllanthaceae) Jing Zhang., Shuxia Wang., Houhun Li*., Bingbing Hu, Xiaofei Yang, Zhibo Wang College of Life Sciences, Nankai University, Tianjin, China Abstract The diffuse coevolution between two moth species (Epicephala lativalvaris and E. mirivalvata) and two plant species (Breynia fruticosa and B. rostrata) is reported based on field observations and indoor experiments conducted in Hainan and Fujian, China. Study results showed that the two Epicephala species jointly pollinated the two Breynia species, which led to a unique obligate pollination mutualism of two2to2two species specificity. A single Epicephala larva exclusively fed on seeds of host plants and developed to maturity by consuming all six seeds of each fruit, whereas a fraction of intact fruits were left to ensure the reproduction of plants within the whole population. Larvae of the two Epicephala species are competitive for resources; the population of E. mirivalvata is much smaller than that of E. lativalvaris, which has resulted from the differences in the female ovipositor structures and oviposition mode. The life history of Epicephala species highly coincides with the phenology of Breynia plants, and different phenology of B. fruticosa resulted in the different life history of the two Epicephala species in Hainan and Fujian. The natural hybridization of two host plants, possibly induced by the alternate pollination of two Epicephala species, is briefly discussed. Citation: Zhang J, Wang S, Li H, Hu B, Yang X, et al.

Evaluation of antibacterial and antioxidant properties of some traditional medicinal plants TICLE R from India A Sreerangegowda Thippeswamy, Rayasandra Umesh Abhishek, Kiragandur Manjunath, Devihalli Chikkaiah Mohana L Department of Microbiology and Biotechnology, Jnanabharathi Campus, Bangalore University, Bengaluru, Karnataka, India A Background: Medicinal plants have been used to prevent and treat various health problems. Aim: The present study was conducted to evaluate the antibacterial and antioxidant activities of aqueous and solvent extracts of some selected medicinal plants. IGIN Materials and Methods: The disc diffusion method was employed for the determination of antimicrobial activity, and antioxidant R activity was evaluated by 2, 2-diphenyl-1-picrylhydrazyl radical scavenging, hydrogen peroxide reducing and ‑carotene/linoleic acid bleaching inhibition assays. Folin-Ciocalteu reagent method was employed for the determination of total phenolic contents. O Results: Aqueous and solvent extracts of Acacia catechu, A. ferruginea, Adenanthera pavonina, Albizia odoratissima, Anogeissus latifolia, Breynia vitis‑idaea, Salacia oblonga, Senna spectabilis and Solanum indicum showed significant antibacterial activity against Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas aeruginosa, Salmonella typhi, Staphylococcus aureus and Streptococcus faecalis, and promising antioxidant properties. The antioxidant activities were positively correlated with total phenolic contents. Discussion and Conclusion: The promising
