| Survey of rice stored pest in The Upper Northern part of Thailand was done in 3 agricultural cooperatives (Nongmuongkai, Maejai and Chiangsaen) using food trap during December 2011 – November 2012. The results showed that 25 stored rice insect pest were found (18 important insect pests and 7 natural enemies). At Nongmoungkai, the important insect pests were Liposcelis spp., Lophocateres pusillus, Sitophillus oryzae and Ceyptolestes pusillus were found with the survey number of 2, 206, 580, 365 and 108 respectively. The natural enemies Xylocoris flavipes was found with the number of 225. At Maejai, the important insect pests were S. oryzae, L. pusillus, L. spp., Rhyzoopertha dominica C. pusillus and Oryzaephilus surinamensis found with the survey number of... |

| Study about the accordance of rice insect pests from the light trap and the research data of insects in the rice seed of San-pah-tawng 1 (weak) and that of SuphanBuri 1 (resistant) was conducted from the year 2011 to 2013 at the Chiang Rai Rice Research Center. It’s found that the rice insect pests entrapped by the light trap being increased from the year 2007 to 2010. That in May, 2011, 4,779 zigzag leafhoppers were mostly found; in March, 2012, 19,248 whitebacked planthoppers were mostly found and; in May, 2013, 19,047 zigzag leafhoppers were mostly found. In the paddy field, rice insect pests were found in the rice seed of San-pah-tawng 1 more than that of Suphan Buri 1. In the In-season rice of the year 2011, the White backed planthoppers were mostly... |

| Insects are important environmental bioindicators, due to the species diversity and wide range of habitats occupied. The present study evaluated the temporal variation in composition and abundance of soil insects in an urban forest fragment in the municipality of Toledo, in the state of Paraná, by analyzing their abundance and seasonality. Monthly samplings were conducted between August 2011 and July 2012 at four sampling sites within the fragment. At each site, three pitfall traps remained exposed for 48 hours. Captured insects were fixed in alcohol, sorted and identified. Throughout the study period, we captured 11,568 insects from 11 orders and 35 families. Coleoptera was the richest order (12 families), followed by Diptera and Hemiptera (5),... |

| The richness and abundance of the assemblage of species in a community are a way to understand the patterns of diversity found around the world. This study describes the assemblages of Saturniidae and Sphingidae in an area of Montana Mixed Ombrophilous Forest, Tijucas do Sul, Paraná, Brazil, 880m, 25º50'8.93"S, 49º 02'55.20"W. Samples were collected between November 2010 and September 2011 during two nights at the twelve new moons periods with a light trap equipped with black light lamp (ultraviolet) of 46 watts between two mercury mixed-light lamps HWL 250 watts from 6:00 p.m to 06:00 a.m. The sampling effort totaled 288 hours. This sampling effort was responsible for the capture of 1235 specimens, distributed in 124 species: 858 specimens and 86 species... |

| Insects associated with sweet potato, Ipomoea batatas were surveyed at Ituporanga Experimental Station, EPAGRI S.A., Santa Catarina State, Brazil, from 1991 to 1994. Astylus variegatus Germ. (Coleoptera: Dasytidae) and Chaetocnema apricaria Suffr. (Coleoptera: Chrysomelidae) were abundant throughout the crop cycle. The complex of Homoptera (Aphididae: Pemphigida e and Cicadellidae), Diabrotica speciosa Germ., and Typophorus nigritus versutus Lef. (Coleoptera: Chrysomelidae) were constantly present but at lower levels than A. variegatus and C. apricaria. Systena sp. (Coleoptera: Chrysomeliadae) and Lagria villosa Fabr. (Coleoptera: Lagriidae), were casual and occurred at low frequency. |

| Abstract: In order to inventory the species richness and fish fauna composition along the Ivinhema river basin, 232 stretches of rivers and streams were sampled from 2000 to 2018, using a rectangular sieve, trawls, gillnets, cast nets, and electrofishing. A total of 141 species was caught in the basin, including seven orders and 35 families. For the recorded species, 42 are from the upper Paraná river, 51 from lower Paraná river, 27 from other basins, two from other continents, and the origin for 19 species are unknown/not reported. Six species are registred for the first time in the upper Paraná river basin: Astyanax abramis, Moenkhausia oligolepis, Serrapinnus kriegi, Curimatopsis myersi, Pyxiloricaria menezesi, and Cichlasoma dimerus. This is the first... |

| Abstract: Habitat fragmentation is one of the principal causes of the decline of species worldwide, and the Brazilian Atlantic Forest and Cerrado savanna biomes are among the most severely affected by this process. While highly fragmented, remnants of Atlantic Forest can still be found within the Cerrado domain of southern Goiás, where previous studies have revealed high levels of biodiversity. To inventory the mammalian species that occur in the region, two fragments of semideciduous Atlantic Forest were sampled between 2011 and 2016, using line transect surveys and camera trapping. A total of 1016 records were obtained of 30 mammal species, of which eleven are under some threat of extinction. The species richness recorded on this study was similar to or... |

| We present data on species composition, relative abundance and estimated densities for leaf-litter anuran amphibians from an Atlantic Forest area within the Parque Estadual do Desengano, in the state of Rio de Janeiro, Brazil, based on results of a short-term survey carried out during the winter at altitudes of 1000-1500 m. Three sampling methods were used: plot sampling, visual encounter surveys (VES; performed during the day, at the twilight, and at night), and pitfall traps. We recorded 13 species, with the direct-developer Ischnocnema parva (Girard, 1853) being the most abundant. Most frogs (ca. 90% of all individuals) sampled by VES were captured during the crepuscular and nocturnal periods. The estimated density of the local leaf-litter frog... |

| Our objectives were to develop a method that would be appropriate for long-term ecological studies, but that would permit rapid surveys to evaluate biotic complementarity and land-use planning in Amazonia. The Amazon basin covers about 7 million km². Therefore, even a sparse coverage, with one sample site per 10.000 km², would require about 700 sampling sites. Financial considerations limit the number of sites and investment at each site, but incomplete coverage makes evaluation of biotic complementarity difficult or impossible (Reddy & Dávalos 2003). Our next challenge is to install similar systems throughout Amazonia. The cost, based on modification of Al Gentry's original design is moderate (less than US$ 50.000 per site if it is not necessary... |

| Infection caused by Toxoplasma gondii, toxoplasmosis, is one of the most frequent zoonoses in the world; it normally affects both genders equally. Humans are one of several possible intermediate hosts, and the disease is oligosymptomatic in most cases. Vertical transmission is an important cause of fetal malformation and sequels in newborns. Approximately 10% of postnatal cases present multiple manifestations, ranging from low fever and mild lymphadenopathy to severe encephalitis. In moderate cases, lesions such as retinochoroiditis may emerge during acute infection or even years later. We analyzed 313 cases of toxoplasmosis from 1992 to 2004, including 261 acute cases. Most patients were women (68.1%), and 39% of these were pregnant. Among acute infection... |
