System Movement pattern Crop Wild Relative Terrestrial Freshwater Nomadic Congregatory/Dispersive Is the species a wild relative of a crop? Marine Migratory Altitudinally migrant Growth From Definition Shrub - size unkno Perennial shrub (any size), also termed a Phanerophyte if >1m or a Chamaephyte if <1m Vines Vines, lianas and creepers Threats D. scandens is a widespread species and unlikely to be threatened with extinction in the near future, however there are large areas of habitat loss occuring within the species range. In particular a large area of natural forest cover has been lost in Rondonia, Brazil. Much of the habitat loss is associated with conversion for agricultural purposes including the cultivation of soya bean and other commerically important crops.

  • Fungal Inhibiting Capacity of an Ethnobotanical Plant from Imugan, Nueva Vizcaya Against Fusarium Oxysporum and Fusarium Moniliforme

Jacob, J. K. S., David, E. S. and Undan, J. R. U. (2016). Fungal inhibiting capacity of an ethnobotanical plant from imugan, nueva vizcaya against Fusarium oxysporum and Fusarium moniliforme. International Journal of Agricultural Technology 12(1):167-171. Abstract Ethnobotany pertains to the scientific association between people and plants. In the Philippines, many researches have been upraised to review the current ethnobotanical state and pharmacological properties of plants thriving for many indigenous tribes. One specific plant used by the Kalanguya tribe of the Northeastern Philippines is Derris elliptica, locally known as Derris elliptica, used as a fish poison, and only minor information was known about this indigenous plant’s taxonomy. This research was undertaken to evaluate the fungal-inhibiting capability of Derris elliptica against two fungal plant pathogens Fusarium oxysporum and Fusarium moniliforme. Hot water extracts of Derris elliptica exhibited fungal inhibition to F. oxysporum as indicated by a retarded mycelial growth response (26.35 mm) compared to its negative control (70.07 mm) after five (5) days of incubation. The same observation was also exuded against F.

Soares1 1Department of Clinical Analysis of Paulista State University “Júlio de Mesquita Filho”, Araraquara, SP, Zip Code 14801-970, Brazil 2Federal University of Amazonas, Manaus, AM, Zip Code 69067-005, Brazil. 3Instituto de Ciências, Engenharia e Tecnologia, Universidade Federal dos Vales do Jequitinhonha e Mucuri, Zip Code 39803-371, Brazil Abstract The genus Deguelia comprises the American species previously included in Derris Lour. Millettia Wight & Arn. and Lonchocarpus subg. Phacelanthus Pittier. Considering the need of systematic definition to the genera Derris, Deguelia and Lonchocarpus, and also the economic importance presented by several species within these genera, which produces rotenone or deguelin (natural insecticides widely used in the past decades), this review is of great chemotaxonomic importance to corroborate studies of botanical systematics carried out with these genera, and guide the search for new therapeutic agents, since this bibliographic survey, approaches the biological and ethnopharmacological studies described for species of this genera. Keywords Fabaceae, ethnopharmacology, flavonoids, chemotaxonomy Introduction The family Fabaceae has cosmopolitan distribution, including about 650 genera and approximately 18,000 species, representing one of the largest families of Angiosperms and one of the leading economically. In Brazil, there are about 200 genera and 1500 species. It was traditionally recognized as a single family with three subfamilies (Papilionoideae or Faboideae, Caesalpinioideae and Mimosoideae), except for Cronquist and other authors who preferred to recognize three distinct families (Fabaceae, Caesalpinaceae and Mimosaceae) [1-2].

The new species has flowers which resemble those of Deguelia duckeana and Deguelia rariflora and it might be closely related to them, probably forming a species complex. However, this new species can be easily distinguished by some morphological and reproductive characteristics. Keywords: Amazon Basin, Neotropics, Deguelia, Leguminosae, new species, liana Introduction Deguelia Aublet (1775: 750) contains ca. 20 species of neotropical trees or scandent shrubs to lianas from the tribe Millettieae (Leguminosae, Papilionoideae). It is distributed from Panama to southeastern Brazil (São Paulo state), mostly in the Amazon Basin in forested habitats. Only one species occurs in the “Cerrado” domain, D. nitidula (Bentham 1860: 98) A. M. G. Azevedo & R. A. Camargo in Camargo & Tozzi (2014: 16), which has the widest distribution for the genus. Deguelia was first described for French Guiana (Aublet 1775) and later synonymized with Derris Loureiro (1790: 432) by Bentham (1860). Some species have been included in Lonchocarpus Kunth in Humboldt et al.

Naturforsch. 59c, 868Ð873 (2004); received June 21, 2004 Random amplified polymorphic DNA (RAPD) marker was used to establish intergeneric classification and phylogeny of the tribe Millettieae sensu Geesink (1984) (Leguminosae: Papilionoideae) and to assess genetic relationship between 9 constituent species belonging to 5 traditionally recognized genera under the tribe. DNA from pooled leaf samples was isolated and RAPD analysis performed using 25 decamer primers. The genetic similarities were derived from the dendrogram constructed by the pooled RAPD data using a similarity index, which supported clear grouping of species under their respective genera, inter- and intra-generic classification and phylogeny and also merger of Pongamia with Millettia. Eleva- tion of Tephrosia purpurea var. pumila to the rank of a species (T. pumila) based on morpho- logical characteristics is also supported through this study of molecular markers.

Received: 1 October 2020; Accepted: 19 October 2020; Published: 21 October 2020 Simple Summary: There is an increasing interest in botanical insecticides worldwide. Plants from the genus Tephrosia are rich in bioactive phytochemicals, particularly rotenoids which include rotenone, deguelin, rotenolone, and tephrosin. Rotenoids have strong insecticidal activities against a wider range of pests. However, there has been no treatise thus far focusing on Tephrosia as insecticidal plants. This article is intended to review phytochemicals produced by selected species, their insecticidal activities, and the current status on the use of Tephrosia as botanical insecticidal plants for insect pest control. Abstract: Synthetic insecticides are effective in controlling insect pests but can also harm nontarget organisms and the environment. During the last 40 years, there has been an increasing interest in alternative insecticides, particularly those derived from plants, commonly known as botanical insecticides. However, commercially available botanical insecticides remain limited. Rotenone is one of the earliest identified compounds and was used as fish poison and pest management.

  • Poison Vine (Derris Elliptica)
    Poison vine (Derris elliptica) An Alien Plant Report Prepared by: Forest Starr, Kim Martz and Lloyd Loope United States Geological Survey Biological Resources Division In cooperation with: American Water Works Association Research Foundation Maui County Board of Water Supply March, 1999 Poison vine (Derris elliptica) What is Poison vine? Why is it bad? Poison vine is a climbing, woody, vine that forms a dense canopy, and smothers vegetation, fences, forests, pastures, and farm land. On Maui, poison vine is currently known to be restricted to a few acres in Nahiku. What should you do if you see this plant in areas other than Nahiku? 1. Call the Hawaii Ecosystems at Risk (HEAR) project at 572-4418. 2. Dig out the root of the vine, if possible. Otherwise, cut the vine near the root of the plant, and treat with an herbicide. 3.

It is known to be invasive in Fiji and western Polynesia. On Maui, poison vine is known from just one location, where it is restricted to 2-3 acres, and landowner has been unsuccessfully trying to control it. This plant may still be eradicable.
