Arnoldo De Winkelried Bertoni
Arnoldo de Winkelried Bertoni (December 28, 1878 – August 1973), also known as Arnaldo da Winkelried, was a Paraguayan zoologist born in Switzerland. Biography He was better known as Arnaldo de Winkelried, his name given in honor of the Swiss soldier Arnold von Winkelried who died at the Battle of Sempach in 1386. In 1887, he emigrated to Paraguay along with his family. He first began studying zoology with his father, the naturalist Moisés Santiago Bertoni in the neighborhood of Guillermo Tell, now called Puerto Bertoni in the Alto Paraná Department of Paraguay, along the Paraná River. Between 1903 and 1906, he served as a professor of zootechnics and zoology at the School of Agriculture and Model Farm, which was opened in 1897 with his father as its director. In 1917, he decided to leave Puerto Bertoni and together with his brother Guillermo Tell they travelled to Asunción where he began to work on his own scientific research, investigating the Paraguayan fauna, chiefly ...

Lottigna
Lottigna is a village and former municipality in the canton of Ticino, Switzerland. It was first recorded in year 1201 as ''Lotingnia''. The municipality also contained the village Acquarossa. It had 105 inhabitants in 1682, and from 1850 to 1950 the population count remained stable around 130. It then dropped to 79 in both 1970 and 2000. In 2004 the municipality was merged with the other, neighboring municipalities Castro, Corzoneso, Dongio, Largario, Leontica, Marolta, Ponto Valentino and Prugiasco Prugiasco is a village and former municipality in the canton of Ticino, Switzerland.

Potter Wasp
Potter wasps (or mason wasps), the Eumeninae, are a cosmopolitan wasp group presently treated as a subfamily of Vespidae, but sometimes recognized in the past as a separate family, Eumenidae. Recognition Most eumenine species are black or brown, and commonly marked with strikingly contrasting patterns of yellow, white, orange, or red (or combinations thereof), but some species, mostly from tropical regions, show faint to strong blue or green metallic highlights in the background colors. Like most vespids, their wings are folded longitudinally at rest. They are particularly recognized by the following combination of characteristics: # a posterolateral projection known as a parategula on both sides of the mesoscutum; # tarsal claws cleft; # hind coxae with a longitudinal dorsal carina or folding, often developed into a lobe or tooth, and; # fore wings with three submarginal cells. Biology Eumenine wasps are diverse in nest building. The different species may either use existi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naturalized Citizens Of Paraguay
Naturalization (or naturalisation) is the legal act or process by which a non-citizen of a country may acquire citizenship or nationality of that country. It may be done automatically by a statute, i.e., without any effort on the part of the individual, or it may involve an application or a motion and approval by legal authorities. The rules of naturalization vary from country to country but typically include a promise to obey and uphold that country's laws and taking and subscribing to an oath of allegiance, and may specify other requirements such as a minimum legal residency and adequate knowledge of the national dominant language or culture. To counter multiple citizenship, some countries require that applicants for naturalization renounce any other citizenship that they currently hold, but whether this renunciation actually causes loss of original citizenship, as seen by the host country and by the original country, will depend on the laws of the countries involved.

Plant Pathology
Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungus, fungi, oomycetes, bacterium, bacteria, plant virus, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrate, or other Plant defense against herbivory, pests that affect plant health by eating Plant tissue, plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, wat ...

Entomology
Entomology () is the science, scientific study of insects, a branch of zoology. In the past the term "insect" was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. This wider meaning may still be encountered in informal use. Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect-related inquiries is, by definition, entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, behavior, neuroscience, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology (biology), morphology, and paleontology. Over 1.3 million insect species have been described, more than two-thirds of all known species. Some insect species date back to around 400 million years ago. Th ...

Pollen Wasp
Pollen wasps, the Masarinae, are unusual wasps that are typically treated as a subfamily of Vespidae, but have in the past sometimes been recognized as a separate family, "Masaridae", which also included the subfamilies Euparagiinae and Gayellinae. It is a small subfamily, unique among wasps in feeding their larvae exclusively with pollen and nectar, in a fashion quite similar to many solitary bees. Most species are black or brown, marked with strikingly contrasting patterns of yellow, white, or red (or combinations thereof). They are most diverse and abundant in the desert regions of southern Africa, but also occur in the deserts of North and South America. Some species of '' Pseudomasaris'' in California, such as ''Pseudomasaris vespoides'', bear a remarkable resemblance to yellow jackets, but can be recognized by their strongly clubbed antennae, a characteristic feature of the subfamily. Males have greatly elongated antennae, but still ending in a strong club. They carry polle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polistinae
The Polistinae is a subfamily of eusocial wasps belonging to the Family (biology), family Vespidae. They are closely related to the more familiar wasps (“yellowjackets” as they are called in North America) and true hornets of the subfamily Vespinae, containing four tribes. With about 1,100 species total, it is the second-most diverse subfamily within the Vespidae, and while most species are tropical or subtropical, they include some of the most frequently encountered large wasps in temperate regions. The Polistinae are also known as paper wasps, which is a misleading term, since other wasps (including the wasps in the subfamily Vespinae) also build nests out of paper, and because some epiponine wasps (e.g., ''Polybia emaciata'') build theirs out of mud, nonetheless, the name "paper wasp" seems to apply mostly, but not exclusively, to the Polistinae, especially the Polistini. Many polistines, such as ''Polistes fuscatus,'' ''Polistes annularis'', and ''Polistes exclamans'', m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
