Forest Management Sheet INVASIVE SPECIES http://texasforestservice.tamu.edu Japanese Privet PLANT: Japanese privet (Ligustrum japonicum) is an evergreen shrub with a spreading canopy, appearing as a single plant or a thicket. IDENTIFICATION: Evergreen, single plant or thicket- forming shrub with spreading canopy to 35 feet tall, thick opposite leaves, both leaves and stems hairless. Leaves are evergreen and leathery, opposite, ovate, 2-4 in. long and 1- 1.8 in. wide. Clusters of showy white flowers in spring yield dangling green to purple fruit in summer to winter. Similar to Chinese privet, only larger with larger leaves. It also resembles redtip. ECOLOGY: It occurs on same habitats as Chinese privet, but generally not as abundant depending upon location. Widely planted as an ornamental and escaped. It invades both lowland and upland habitats. Spreads by abundant animal-dispersed seeds and colonizes by rootsprouts. HERBICIDE CONTROL: Apply Garlon 4 as a 3% solution (12 ounces per 3-gal. mix) or Arsenal AC as a 1% solution (4 ounces per 3-gal. mix) in water with a surfactant to thoroughly wet all leaves in August through September. Apply a glyphosate herbicide as a 3% solution (12 ounces per 3-gal. mix) in water with a surfactant in March to June. For stems too tall for foliar sprays, apply a Garlon 4 as a 20% solution (2 quarts per 3-gal. mix) in commercially available basal oil, diesel fuel, or kerosene with a penetrant (check with herbicide distributor) to young bark as a basal spray. Cut large stems and treat stumps immediately after cutting with 10% solutions of Arsenal AC, Chopper, or Velpar L (1 quart per 3-gal. mix) in water with a surfactant (can damage desirable trees with roots in treated zone). When safety to surrounding vegetation is desired, carefully treat stumps and cut stems with a glyphosate herbicide or Garlon 3A using 20% solutions (2 quarts per 3-gal. mix) in water with a surfactant.

EENY-704 Delta Flower Beetle Trigonopeltastes delta (Forster 1771) (Insecta: Coleoptera: Scarabaeidae : Cetoniinae : Tribe, Trichiini)1 Brandon Jones and Andrea Lucky2 Introduction The delta flower beetle, Trigonopeltastes delta (Forster), is a member of the scarab beetle family Scarabaeidae, in the subfamily Cetoniinae. This subfamily is commonly known as flower or fruit chafers because their diet consists mostly of decomposing fruits or pollen (Cave and Ratcliffe 2008). Trigonopeltastes delta belongs to the tribe Trichiini, which contains mostly flower-frequenting species. Although this species is commonly encountered where it occurs, many details of its life cycle and its potential economic importance remain poorly studied. Like many other cetoniines, the delta flower beetle has bright colors and distinctive patterns that distinguish it from other similar species (Figure 1). The delta flower beetle is one of two species in Florida, but while Trigonopeltastes delta is a familiar sight, Trigono- Figure 1. Adult Trigonopeltastes delta (Forster) (dorsal view). peltastes floridana is extremely rare (Woodruff 1960). While Credits: Mike Quinn, TexasEnto.net they are superficially similar, these species are distinguished by distinctive yellow markings on the pronotum. Trigono- Etymology and Synonymy peltastes delta bears a triangular mark whereas Trigono- The name Trigonopeltastes delta is Greek in origin and peltastes floridana has a U- or V-shaped mark. describes the pronotal markings of the species. Trigon translates to triangle, pelt translates to a shield, and delta originates from the letter Δ, or delta. The Greek symbol for delta is a triangle, which resembles the beetle’s pronotal marking, and accounts for its common name. 1.

Taxonomic Overview of Ligustrum (Oleaceae) Naturalizaed in North America North of Mexico
Phytologia (December 2009) 91(3) 467 TAXONOMIC OVERVIEW OF LIGUSTRUM (OLEACEAE) NATURALIZAED IN NORTH AMERICA NORTH OF MEXICO Guy L. Nesom 2925 Hartwood Drive Fort Worth, TX 76109, USA www.guynesom.com ABSTRACT A key, morphological descriptions, and basic synonymy are provided for the eight species of Ligustrum known to be naturalized in North America north of Mexico: L. japonicum, L. lucidum, L. obtusifolium (including L. amurense), L. ovalifolium, L. quihoui, L. sinense, L. tschonoskii, and L. vulgare. Identifications have been inconsistent particularly between L. sinense and L. vulgare and between L. japonicum and L. lucidum. The occurrence of L. quihoui outside of cultivation in Arkansas, Mississippi, and Oklahoma is documented. Phytologia 91(3): 467-482 (December, 2009). KEY WORDS: Ligustrum, Oleaceae, North America, naturalized, taxonomy The lustrous, mostly evergreen leaves and masses of white, fragrant flowers make privets popular for landscaping and hedges. Many of the species, however, have become naturalized in the USA and Canada and already have proved to be destructive colonizers, especially in the Southeast. Among the naturalized species, European privet (Ligustrum vulgare) is native to Europe and northern Africa; all the rest are native to Asia, mainly China, Japan, and Korea. Many new species and varieties of Ligustrum have been described since overviews of Koehne (1904), Lingelsheim (1920), and Mansfield (1924). The genus in eastern Asia has recently been studied by Chang & Miao (1986), and Qin (2009) has provided a taxonomic overview of the whole genus that recognizes 37 species - divided into five sections based primarily on fruit and seed morphology. In Qin’s arrangement, among the North American species, sect.

Non-Native Invasive Plants of the City of Alexandria, Virginia
March 1, 2019 Non-Native Invasive Plants of the City of Alexandria, Virginia Non-native invasive plants have increasingly become a major threat to natural areas, parks, forests, and wetlands by displacing native species and wildlife and significantly degrading habitats. Today, they are considered the greatest threat to natural areas and global biodiversity, second only to habitat loss resulting from development and urbanization (Vitousek et al. 1996, Pimentel et al. 2005). The Virginia Department of Conservation and Recreation has identified 90 non-native invasive plants that threaten natural areas and lands in Virginia (Heffernan et al. 2014) and Swearingen et al. (2010) include 80 plants from a list of nearly 280 non-native invasive plant species documented within the mid- Atlantic region. Largely overlapping with these and other regional lists are 116 species that were documented in the City of Alexandria, Virginia during vegetation surveys and natural resource assessments by the City of Alexandria Dept. of Recreation, Parks, and Cultural Activities (RPCA), Natural Lands Management Section. This list is not regulatory but serves as an educational reference informing those with concerns about non-native invasive plants in the City of Alexandria and vicinity, including taking action to prevent the further spread of these species by not planting them. Exotic species are those that are not native to a particular place or habitat as a result of human intervention. A non-native invasive plant is here defined as one that exhibits some degree of invasiveness, whether dominant and widespread in a particular habitat or landscape or much less common but long-lived and extremely persistent in places where it occurs.

Identification and Control of Invasive Privets (Ligustrum Spp.) in the Middle Southern United States
Invasive Plant Science and Management 2010 3:482–488 Notes and Commentary Identification and Control of Invasive Privets (Ligustrum spp.) in the Middle Southern United States Victor Maddox, John Byrd, Jr., and Brett Serviss* The identification of privet in the middle southern United States can be difficult. Because most introduced species of privet can be invasive, and recent mapping projects seek location and species population data, proper identification is important. Without proper identification of privet species, data on species distributions and other pertinent information regarding invasiveness could lead to improper conclusions. Currently, information on privet identification is scattered throughout a number of reference materials. The purpose of this publication is to assist with the proper identification of escaped privet species, and suggest management options.

Ligustrum Japonicum Japanese Privet1 Edward F
Fact Sheet ST-352 November 1993 Ligustrum japonicum Japanese Privet1 Edward F. Gilman and Dennis G. Watson2 INTRODUCTION Although often used as a shrub or hedge, Japanese Privet works well when allowed to grow into a small tree, its curved multiple trunks and dark green canopy creating an interesting architectural focus, 8 to 12 feet tall and often considerably wider, for the landscape (Fig. 1). Old specimens can grow to 25 feet across. The glossy evergreen leaves are abundantly produced on the upright, spreading branches. The small, white, malodorous flowers appear in terminal panicles during spring in the south and in the summer in northern climes. The blooms are followed by abundant blue- black berries which persist most of the year. The Figure 1.

On the one hand, plants keep stomata open for efficient carbon assimilation while, on the other hand, they close them to prevent permanent hydraulic im- pairment from xylem embolism. The order of occurrence of these two processes (stomatal closure and the onset of leaf embolism) during plant dehydration has remained controversial, largely due to methodological limitations. However, the newly developed optical visualization method now allows concurrent monitoring of stomatal behaviour and leaf embolism formation in intact plants.
