(Coleoptera: Curculionoidea) В Сербии И Черногории

Дан краткий обзор истории изучения фауны долгоносикообразных жуков (Coleoptera: Curculionoidea) на территории Сербии и Черногории. Изучаемая фауна рассмотрена в сравнении с мировой и европейской фаунами. Ключевые слова. Долгоносикообразные жуки, Coleoptera, Curculionoidea, фауна, Сербия и Черно- гория. Abstract. A brief review of the history of investigation of the weevil fauna (Coleoptera: Curculionoidea) on the territory of Serbia and Montenegro is given. The fauna is compared with that of the World and Europe. Key words. Rhynchophorous beetles, Coleoptera, Curculionoidea, fauna, Serbia and Montenegro. Краткая характеристика мировой и европейской фаун долгоносиков Отряд жесткокрылые, или жуки (Coleoptera), насчитывает более полумиллиона видов, что составляет почти треть животного мира (Lekić, Mihajlović, 1970). По некоторым новым оценкам, число видов жуков на Земле может составлять около одного, а то и двух миллионов. Бόльшая часть видов – обитатели суши, где они населяют самые разнообразные биотопы от пустынь через джунгли, леса умеренного пояса, травянистые сообщества, болота и другие ландшафты до самых высоких горных вершин. Только в морях жуков почти нет (если не считать водных жуков в опрес- ненных прибрежных участках). По-разному оценивается число видов долгоносиков (Curculionoidea) в мировой фауне, по- скольку они в разных частях света изучены не с одинаковой полнотой. -
Spruce Spider Mite Oligonychus Ununguis Order Acari, Family Tetranychidae; Spider Mites Native Pest
Pests of Trees and Shrubs Spruce spider mite Oligonychus ununguis Order Acari, Family Tetranychidae; spider mites Native pest Host plants: Blue spruce, Norway, and white spruce are preferred, but arborvitae, cedar, cryptomeria, dawn redwood, Douglas-fir, hemlock, juniper, larch, and pine, are also susceptible. Description: Adult mites are approximately 0.5 mm long with eight legs. They are dark green when young but turn darker green as they mature. Protonymphs are smaller and lighter. Eggs are reddish-orange and oval to circular. Life history: This is a cold tolerant spider mite not active in hot summer temperatures. Eggs hatch in April and May. Feeding damage may be first observed after feeding started. Activity eases in summer with the arrival of 90 degree F temperatures and resumes with cooler weather in fall. There are several generations a year. Overwintering: Eggs on bark and needles. Damage to blue spruce in June caused by spruce spider mite; Damage symptoms: Mite feeding causes color changes note discoloration on the older needles. (234) in needles, giving them first a mottled appearance, then Photo: Cliff Sadof turning needles yellow and finally bronze. Damaged needles may drop prematurely. Severe infestations can cause loss of foliage, twig dieback, even branch dieback. Host trees may be killed, if extremely heavy infestations occur when they are stressed. Monitoring: Eggs hatch when PJM rhododendron blooms in mid April (Herms). Look for fine stippling turning into bronzing of needles beginning in June. To confirm mite presence, hold a sheet of white paper under a branch and tap the branch to dislodge mites. -
TREES AS CROPS in ALASKA PROFILE with an EMPHASIS on SPRUCE Revised 2009
TREES AS CROPS IN ALASKA PROFILE WITH AN EMPHASIS ON SPRUCE Revised 2009 Robert A. Wheeler Thomas R. Jahns Janice I. Chumley PRODUCTION FACTS Growing trees in Alaska can be difficult. This document addresses basic questions regarding growing tree seedlings as an agricultural crop. Whether growing a few seedlings or thousands, many of the basic production questions are the same. From the standpoint of tree seedling production there are three basic regions in Alaska: Southeast, South Central, and the Interior. Producing high quality tree seedlings is 4-H Tree Sale in Soldotna, AK May 2003 achievable in all three regions however care must (photo/Bob Wheeler). be taken to match tree species requirements with local environmental conditions. Through the efforts of the University of Alaska Fairbanks and the Agriculture and Forestry Experiment Station, many tree species have been evaluated over the past 100 years for their performance. Results from these species trials have led to the listing of tree species, growth characteristics, and site requirements found in Table 1. DEMAND Interest in tree production can vary from growing trees for your yard or property to full scale outdoor or greenhouse, bareroot, or container nurseries. Tree planting and tree sales continue to be of considerable interest to the public although there are no large-scale commercial tree nurseries currently operating in Alaska. A state tree nursery was once operated in the Matanuska Valley area, but it has been closed. Reasons for the closure were based upon the high cost of producing seedlings in Alaska versus what it would cost to import them from nurseries outside the state and also, the overall operational difficulties and risks associated with an Alaska nursery program. -

In Europe, it is an indige- nous species, commonly found on various plants, including conifers. The present study examined whether A. andersoni can develop and reproduce while feeding on two key pests of ornamental coniferous plants, i.e., Oligonychus ununguis (Jacobi) and Pentamerismus taxi (Haller). Pinus sylvestris L. pollen was also tested as an alternative food source for the predator. Both prey species and pine pollen were suitable food sources for A. andersoni. Although higher values of population parameters Citation: Puchalska, E.; were observed when the predator fed on mites compared to the pollen alternative, we conclude that Zagrodzki, S.K.; Kozak, M.; pine pollen may provide adequate sustenance for A. -

Vermont Forests 2017
United States Department of Agriculture Vermont Forests 2017 Forest Service Northern Resource Bulletin Publication Date Research Station NRS-120 March 2020 Abstract The second full remeasurement of the annual inventory of the forests of Vermont was completed in 2017 and covers nearly 4.5 million acres of forest land, with an average volume of over 2,300 cubic feet per acre. The data in this report are based on 1,125 plots located across Vermont. Forest land is dominated by the maple/beech/birch forest-type group, which occupies 71 percent of total forest land area. Of the forest land, 70 percent consists of large diameter trees, 23 percent contains medium diameter trees, and 7 percent contains small diameter trees. The volume of growing stock on timberland has continued to increase since the 1980s and currently totals nearly 9 billion cubic feet. The average annual net growth of growing stock on timberland from 2012 to 2017 was nearly 160 million cubic feet per year. Additional information is presented on forest attributes, land use change, carbon, timber products, species composition, regeneration, and forest health. Sets of supplemental tables are available online at https://doi.org/10.2737/NRS-RB-120 and contain summaries of quality assurance data and a core set of estimates for a variety of forest resources. Acknowledgments The authors would like to thank inventory crew members from Vermont for their help during the 2008–2017 inventory years: Aaron Clark, Robert Gregory, John Higham, Katherine Locke, Jason Morrison, Joyce Quinn, Bryan Tirrell, and Ashley Zickefoose. Thanks also to Paul Frederick and Barbara Schultz for serving as reviewers and providing insightful, constructive comments. -
