Adult beetles and larvae are easily killed when sprayed with the recommended insecticide. Mix three tablespoons of 80% SP sevin in one Identification: gallon of water. Cover foliage well with spray. Adult beetles are approximately ¼ inch long, and yellowish or greenish with black outer margins on the wingcov- ers. Legs and antennae are yellowish-green in color. Larvae are about ½ inch long and yellowish-green with two black stripes along the back. The head and legs are black. The pupae are about ¼ inch long and yellow-orange with a few black hairs. Eggs are small, spindle shaped, and yellowish- orange. Signs of Attack: Skeletonized or shriveled brownish leaves are usually the first indication of an attack by this beetle. Examination of the leaves may reveal beetles, larvae or eggs. Life Cycle: Adult beetles overwinter in protected places near the host tree, especially around buildings. In spring, they fly to the trees and begin feeding on new leaves. Mating and egg lay- ing takes place shortly and each female lays up to 25 yellow eggs in a mass on the underside of a leaf. A female beetle can lay several hundred eggs during her lifetime. Eggs hatch and larvae feed voraciously on leaves for two to four weeks. The larvae then crawl to some sheltered place on the tree or ground to pupate. In approximately two weeks, adults emerge to begin the cycle again. There are approximately three generations per year. http://tfsweb.tamu.edu Page 1 of 1.

Elms Grown in America
ARNOLDIA A continuation of the BULLETIN OF POPULAR INFORMATION of the Arnold Arboretum, Harvard University VOLUME I DECEMBER I 9, 19411 NUMBER IS ELMS GROVG’N IN AMERICA years ago, Professor Charles S. Sargent, Director T~’ENTY-FIVEof the Arnold Arburetum w rote the following statement concerning the European Elms-unfortunately just as true today as it was then - "There is probably more confusion in the identification and proper naming of these trees (the European elms) in American parl.s and gar- dens than of any other group of trees, and it is only in very recent ~ ears that English botanists have been able to reach what appear to be sound conclusions in regard to them. The confusion started with Lin- naeus, who believed that all European elms belonged to one species, and it has been increased by the appearance of natural hybrids of at least two of the species and by the tendency of seedlings to show much variation from the original types." Today, with six elm species native in the United State, five species native of Europe (including many varieties), and se‘ eral more species native of Asia, the picture becomes even more confused. The elm is, and always has been, a standard shade tree, for even though it is threatened in certain sections by the Dutch elm disease, the gardening public will still plant elms. Approximately fifty elms will be mentioned in this bulletin. About thirty of them have been listed as available in - the nurseries of this country during the past two years : all but five of them are growing in the Arnold Arboretum at Boston.

Moreover, for no very obvious reason, in the twenty-nine years of its publication it has attamed four series, and for clarity it is necessary to cite the series as well as the volume.

The internal sac of P. maculicollis bears hand saw-like spines, which are arranged in a row. Healing wounds were found on the vagina of this species, whose females were collected in the field during a repro- ductive season. However, the number of the wounds is low in comparison to the number of the spines.

Insects for Weed Control: Status in North Dakota
Insects for Weed Control: Status in North Dakota E. U. Balsbaugh, Jr. Associate Professor, Department of Entomology R. D. Frye Professor, Department of Entomology C. G. Scholl Plant Protection Specialist, North Dakota State Department of Agriculture A. W. Anderson Associate Professor, Department of Entomology Two foreign species of weevils have been introduced into North Dakota for the biological control of musk thistle, Carduus nutans L. - Rhinocyllus conicus (Froelich), a seed feeding weevH, and Ceutorrhynchidius horridus (Panzer), an internal root and lower stem inhabiting species. R. conicus has survived for several generations and is showing some promise for thistle suppression in Walsh County, but releases of C. hor ridus have been unsuccessful. The pigweed nea beetle, Disonycha glabrata (Fab.), which is native in southern United States, has been introduced into experimental sugarbeet plots in the Red River Valley for testing its effects at controlling rough pigweed or redroot, Amaranthus retroflexus L. Although both larvae and adults of these beetles feed heavily on pigweed, damage to the weed occurs too late in the season for them to be effective in suppressing weed growth or seed set. An initial survey for native insects of bindweed has been conducted. Feeding by localized populations of various insects, particularly tortoise beetles, has been observed. Several foreign species of nea beetles and a stem boring beetle are anticipated for release against leafy spurge. Entomologists at North Dakota State University are successful. In 1940, the cactus-feeding moth, Cac studying insects that feed on weeds to determine if the toblastis cactorum (Berg), was transported from its insects can reduce populations of selected weeds to native Argentina to Australia where it greatly reduced levels at which the weeds no longer are economically im the numbers of prickly pear cactus, Opuntia spp.

Ulmus 'Patriot'
Ulmus ‘Patriot’ The U.S. National Arboretum presents Ulmus ‘Patriot’, a hybrid elm for planting sites demanding a big, tough tree. ‘Patriot’ was bred and selected for pest and disease tolerance and a wide, vase-shaped crown. Fast-growing and highly tolerant to Dutch elm disease, it is easily established in the nursery or landscape. Select ‘Patriot’ for those park, lawn or highway sites requiring a tree of exceptional vigor. U.S. National Arboretum Plant Introduction Floral and Nursery Plants Research Unit U.S. National Arboretum, U.S. Department of Agriculture, Agricultural Research Service, 3501 New York Ave. NE., Washington, DC 20002 ‘Patriot’ hybrid elm Botanical name: Ulmus ‘Patriot’ (U. ‘Urban’ × U. davidiana var. japonica ‘Prospector’) (NA 60071; PI 566597) Family: Ulmaceae Hardiness: USDA Zones 4–9 Development: ‘Patriot’ resulted from a controlled pollination made in 1980 by A. M. Townsend between Ulmus 'Urban' (a complex hybrid involving U. pumila, U. ×hollandica, and U. minor) and a selection of the Asian elm U. davidiana var. japonica that was later released as ‘Prospector’. ‘Patriot’ was selected initially for its tolerance to Dutch elm disease in field inoculation studies in Delaware, Ohio, and Glenn Dale, Maryland. In further field and laboratory evaluations, ‘Patriot’ showed the highest level of elm leaf beetle tolerance of more than 600 hybrids resulting from the 1980 cross. Released 1993. Significance: ‘Patriot’ is a hybrid elm with a moderately vase-shaped crown, showing high levels of tolerance to two of the major disease and insect pests of landscape elms. It has also shown field tolerance to natural infections of elm yellows.

Leaf Beetle Larvae
Scottish Beetles BeesIntroduction and wasps to Leaf Beetles (Chrysomelidae) There are approximately 281 species of leaf beetles in the UK. This guide is an introduction to 17 species found in this family. It is intended to be used in combination with the beetle anatomy guide and survey and recording guides. Colourful and often metallic beetles, where the 3rd tarsi is heart shaped. Species in this family are 1-18mm and are oval or elongated oval shaped. The plants each beetle is found on are usually key to their identification. Many of the species of beetles found in Scotland need careful examination with a microscope to identify them. This guide is designed to introduce some of the leaf beetles you may find and give some key Dead nettle leaf beetle (Chrysolina fastuosa ) 5-6mm This leaf beetle is found on hemp nettle and dead nettle plants. It is beautifully coloured with its typically metallic green base and blue, red and gold banding. The elytra are densely punctured. Where to look - Found mainly in wetlands from March to December from the Central Belt to Aberdeenshire and Inverness © Ben Hamers © Ben Rosemary leaf beetle (Chrysolina americana ) 6-8mm The Rosemary beetle is a recent invasive non- native species introduced to the UK through the international plant trade. This beetle is metallic red/burgundy with green striping. There are lines of punctures typically following the green stripes. Where to look - Found in nurseries, gardens and parks. Feeds on lavender and rosemary in particular. There have been records in Edinburgh but this beetle is spreading.

Entomological Notes: Elm Leaf Beetle
College of Agricultural Sciences Cooperative Extension Entomological Notes Department of Entomology ELM LEAF BEETLE Xanthogaleruca luteola (Muller) The elm leaf beetle is an introduced pest that feeds only on species of elm, Ulmus spp. Although all elm species are subject to attack, this species usually prefers Chinese elm, Ulmus parvifolia. Trees growing in landscapes are more heavily infested than those found in forests. DESCRIPTION Eggs are orange-yellow and spindleshaped. Larvae are small, black, and grublike. At maturity larvae are approximately 13 mm long, dull yellow, and with what appears to be two black stripes down the back. Adults are about 6 mm long, yellowish to olive green with a Figure 1.
