ZooKeys , 2011, DOI: 10.3897/zookeys.135.1624
Abstract: Camptochaeta prolixa sp. n. (Diptera, Sciaridae) is described from caves in Nevada, and three other congeneric species are recorded from caves in Nevada and Arkansas, United States. The new species shows some indication to a subterranean mode of life, including long antenna and legs, and in some specimens, reduction of the eye bridge.

Revista Brasileira de Entomologia , 2011, DOI: 10.1590/S0085-56262011000100003
Abstract: a new name for the neotropical genus aniarella enderlein (diptera, sciaridae). a junior homonym was detected among neotropical sciarid flies genera and the following replacement name is proposed: novaniarella nom. nov. for aniarella enderlein, 1911 (nec bolivar, 1906). accordingly, new combinations are herein proposed for the species currently included in this genus: novaniarella azteca (lane, 1959) comb. nov., novaniarella brevis (rubsaamen, 1894) comb. nov. and novaniarella pelluscens (enderlein, 1911) comb. nov.

Abstract: we determined the genome size of the brazilian sciarid flies bradysia hygida, rhynchosciara americana and trichosia pubescens (diptera: sciaridae) using absorbance measurements of feulgen-stained nuclei belonging to these species (and chicken erythrocytes as a standard) to calculate the amount of dna in picograms (pg) and the number of base pairs (bp), or c-value, for each of these species. the c-values were: 3 x 108 bp (0.31 pg) for b. hygida; 3.6 x 108 bp (0.37 pg) for r. americana; and 1 x 109 bp (1.03 pg) for t. pubescens. the sciarids investigated in this work had considerably higher c-values than the average for previously described dipteran species, including d. melanogaster.

Revista Brasileira de Zoologia , 1993, DOI: 10.1590/S0101-81751993000200012
Abstract: in nature, the sciaridae live in moist and shady places, where exists vegetable material in decomposition. it is very dificult to determine the proper sciaridae's alimentary habit and then, it is dificult, also, to rear sciaridae species in laboratory. to improvement the bradysia hygida rearing, the objectives of this research were to analyse the nutritive value of mucuna bean foliage for the larves, to verify the role of the ground (as larvae substrate and in diet composition) and also to verify the possibility of ground substituition by another kind of substrate. two kinds of sand were employed in the place of the ground and three diets, free of ground, were prepared. the parameters analysed were: duration of the life cicle, porcentage of emergence, egg production by female and adult size. the results showed that the mucuna bean foliage have a good nutritive value for b. hygida rearing; the ground, as substrate, can be substituted by any of the sands and the ground, in the diet, is also dispensable. the alimentary habits of sciaridae is discussed.

Abstract: 通过药剂水培法,研究比较了不同培养条件对7种新烟碱类杀虫剂在韭菜中的内吸性及其对韭菜迟眼蕈蚊Bradysia odoriphaga (Diptera: Sciaridae) 4龄幼虫的毒力。结果表明:随着水培时间的延长,韭菜中7种杀虫剂对供试幼虫的毒力均呈增强的趋势,其中在100 mg/L下,噻虫胺和吡虫啉产生毒力作用较快,水培72 h时对幼虫的致死率分别为32.38%和36.50%,168 h时,呋虫胺的致死率最高,达96.35%;同一药剂在相同浓度下处理,内吸至韭菜叶部产生的致死作用快于内吸至假茎所产生的作用,并且致死率更高;水培温度及药液浓度越高,内吸后毒力产生越快,且致死率越高。表明新烟碱类杀虫剂可以通过韭菜根部处理防治咀嚼式口器害虫韭菜迟眼蕈蚊。
The systemic activity of 7 neonicotinoid insecticides in leeks and its toxicity against the 4th instar larvae of Bradysia sarcophaga (Diptera: Sciaridae) were studied and compared by hydroponic method under different cultivated conditions. The results showed that with the prolonging of the hydroponic time, the toxicities of the 7 insecticides inside the leek against the larvae were all enhanced. Under concentration of 100 mg/L, the generation of the systemic toxicity of clothianidin and imidacloprid was faster than that of the other neonicotinoid insecticides, causing mortalities of the 4th instar larvae 32.38% and 36.50% at 72 h, respectively; The mortality of dinotefuran reached the highest, which was 96.35% at 168 h. When treated by the same concentration of one insecticide, the generation of lethal activity in leek foliage was faster and the mortality was higher than that of the stem. The higher the cultivated temperature and solution concentration tested, the faster the generation of toxicity and the higher the mortality showed. The results of present study indicated neonicotinoid insecticides could be used to control the chewing mouthparts larvae of B. odoriphaga in leeks through root treatment.

Chinese Science Bulletin , 2000, DOI: 10.1007/BF02887106
Abstract: Based on GPS data during May 1995-March 1998 of 12 IGS stations located in the Chinese mainland and its surrounding areas, the horizontal displacement rates of these IGS stations have been determined. The result can be available to study the background of the crustal tectonic motion in the Chinese mainland.
The last sunset on mainland Europe  [PDF]

Physics , 2014,
Abstract: This paper documents the places in mainland Europe at which the sun sets latest, by Coordinated Universal Time (UTC), on any given day (distortion due to differences in local standard times is ignored). In contradiction to the na\"ive assumption that the sun always sets latest at the westernmost point, the point of last sunset changes cyclically over the course of a year due to the changing orientation of the axis of the Earth with respect to the sun. Specifically, between the winter and summer solstices the last sunset shifts successively from Cabo de Sao Vicente (Portugal) to Cabo da Roca (Portugal) to Cabo Tourinan (Spain) to a site near Aglapsvik (Norway) to a location in the Norwegian municipality of Masoy south of Havoysund; and it shifts back again between the summer and winter solstices. There are two days in the year (April 24th and August 18th) on which the last sunset of mainland Europe (shared in those days effectively by Cabo Tourinan and the Aglapsvik area) coincides with the last sunset of mainland Africa, at a site in Western Sahara near Cap Blanc. A similar analysis of the first Spanish sunrise shows that from April 22nd to August 20th it occurs on the Costa Brava at Cap de Creus (Catalonia), and the rest of the year at Punta de s'Espero (Balearic Islands), the easternmost point of Spain.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0034896
Abstract: The genus Culicoides (Diptera: Ceratopogonidae) contains important vectors of animal and human diseases, including bluetongue, African horse sickness and filariosis. A major outbreak of bluetongue occurred in mainland Portugal in 2004, forty eight years after the last recorded case. A national Entomological Surveillance Plan was initiated in mainland Portugal, Azores and the Madeira archipelagos in 2005 in order to better understand the disease and facilitate policy decisions. During the survey, the most prevalent Culicoides species in mainland Portugal was C. imicola (75.3%) and species belonging to the Obsoletus group (6.5%). The latter were the most prevalent in Azores archipelago, accounting for 96.7% of the total species identified. The Obsoletus group was further characterized by multiplex Polymerase Chain Reaction to species level showing that only two species of this group were present: C. obsoletus sensu strictu (69.6%) and C. scoticus (30.4%). Nine species of Culicoides were detected for the first time in mainland Portugal: C. alazanicus, C. bahrainensis, C. deltus, C. lupicaris, C. picturatus, C. santonicus, C. semimaculatus, C. simulator and C. subfagineus. In the Azores, C. newsteadi and C. circumscriptus were identified for the first time from some islands, and bluetongue vectors belonging to the Obsoletus group (C. obsoletus and C. scoticus) were found to be widespread.

Xiaoyan Gao,Roger Nasci,Guodong Liang
PLOS Neglected Tropical Diseases , 2010, DOI: 10.1371/journal.pntd.0000624
Abstract: The major arboviral diseases in mainland China include Japanese encephalitis, dengue fever, Crimean-Congo hemorrhagic fever (also known as Xinjiang hemorrhagic fever), and tick-borne encephalitis. These and other newly found arbovirus infections due to Banna virus and Tahyna virus contribute to a large and relatively neglected disease burden in China. Here we briefly review the literature regarding these arboviral infections in mainland China with emphasis on their epidemiology, primary vectors, phylogenetic associations, and the prevention programs associated with these agents in China.
