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. -
Biological Control of Lantana, Prickly Pear, and Hamakua Pamakani Inhawah: a Review and Update
BIOLOGICAL CONTROL OF LANTANA, PRICKLY PEAR, AND HAMAKUA PAMAKANI INHAWAH: A REVIEW AND UPDATE Clifton J. Davis, Ernest Yoshioka, and Dina Kageler ABSTRACT The biological control of noxious weeds in Hawai`i has been carried on intermittently since 1902, when insects and diseases of lantana (Lantana camara) were sought in Mexico by the Territorial Board of Agriculture and Forestry (now Hawai`i Department of Agriculture). This approach was subsequently employed for the control of 20 other noxious weed pests between the 1940s and 1970s. Lantana was the first weed to be controlled by this method in the U.S. Results were very dramatic in some areas of the State, especially after later introductions by Hawai`ian and Australian entomologists resulted in heavy stress on lantana. In addition to lantana, excellent results have been obtained in the biological control of cacti (Opuntia spp.), and Hamakua pamakani (Ageratina riparia). Prior to the introduction of cactus insects in 1949, 66,000 a (26,400 ha) of Parker Ranch range lands on Hawai`i Island were infested with cacti. By 1965, 7,610 a (< 3,080 ha) remained infested, the result of three introduced insects and an accidentally introduced fungus disease; the red-fruited variety of cactus is particularly susceptible to the fungus. A spineless variety of the cactus occurs in the 'Ainahou-Poliokeawe Pali sector of Hawai`i Volcanoes National Park, and biocontrol efforts are in progress. With the introduction of insects from Mexico and a foliar fungus disease from Jamaica, Hamakua pamakani is under excellent control on many ranch as well as privately owned and government lands on Hawai`i Island. -
Well-Known Plants in Each Angiosperm Order
Well-known plants in each angiosperm order This list is generally from least evolved (most ancient) to most evolved (most modern). (I’m not sure if this applies for Eudicots; I’m listing them in the same order as APG II.) The first few plants are mostly primitive pond and aquarium plants. Next is Illicium (anise tree) from Austrobaileyales, then the magnoliids (Canellales thru Piperales), then monocots (Acorales through Zingiberales), and finally eudicots (Buxales through Dipsacales). The plants before the eudicots in this list are considered basal angiosperms. This list focuses only on angiosperms and does not look at earlier plants such as mosses, ferns, and conifers. Basal angiosperms – mostly aquatic plants Unplaced in order, placed in Amborellaceae family • Amborella trichopoda – one of the most ancient flowering plants Unplaced in order, placed in Nymphaeaceae family • Water lily • Cabomba (fanwort) • Brasenia (watershield) Ceratophyllales • Hornwort Austrobaileyales • Illicium (anise tree, star anise) Basal angiosperms - magnoliids Canellales • Drimys (winter's bark) • Tasmanian pepper Laurales • Bay laurel • Cinnamon • Avocado • Sassafras • Camphor tree • Calycanthus (sweetshrub, spicebush) • Lindera (spicebush, Benjamin bush) Magnoliales • Custard-apple • Pawpaw • guanábana (soursop) • Sugar-apple or sweetsop • Cherimoya • Magnolia • Tuliptree • Michelia • Nutmeg • Clove Piperales • Black pepper • Kava • Lizard’s tail • Aristolochia (birthwort, pipevine, Dutchman's pipe) • Asarum (wild ginger) Basal angiosperms - monocots Acorales -

Hence, there is a tendency of species misidentification using only the mor- phological characters. Herein, we evaluated the discriminatory power of the universal DNA barcodes (matK and rbcL) for 53 species spanning the two families. Using these markers, we inferred phylogenetic relation- ships and conducted species delimitation analysis using four delimitation methods: Automated Barcode Gap Discovery (ABGD), TaxonDNA, Bayesian Poisson Tree Processes (bPTP) and General Mixed Yule Coalescent (GMYC). The phylogenetic reconstruction based on the matK gene resolved the relationships between the families and further suggested the expansion of the Lamiaceae to include some core Verbanaceae genus, e.g., Gmelina. -

FULL ACCOUNT FOR: Ageratina riparia Ageratina riparia System: Terrestrial Kingdom Phylum Class Order Family Plantae Magnoliophyta Magnoliopsida Asterales Asteraceae Common name Synonym Eupatorium riparium , Regel Similar species Summary Ageratina riparia is a popular ornamental plant that has been widely spread from its home region in Central America. It is naturalised in many tropical regions of the world and is invasive in some such as Hawaii, Australia and the islands of the Indian Ocean. It can form dense quasi monospecific stands which crowd out native plants, limiting their regeneration. view this species on IUCN Red List Principal source: Compiler: Comité français de l'UICN (IUCN French Committee) & IUCN SSC Invasive Species Specialist Group (ISSG) Review: Pubblication date: 2008-03-14 ALIEN RANGE [1] AUSTRALIA [2] MAURITIUS [1] NEW ZEALAND [1] REUNION [1] UNITED STATES Red List assessed species 3: EX = 2; EN = 1; Mixophyes fleayi EN Rheobatrachus silus EX Taudactylus diurnus EX BIBLIOGRAPHY 7 references found for Ageratina riparia Managment information General information Global Invasive Species Database (GISD) 2021.
