| The taxonomic composition and diversity of assemblages of Ephemeroptera nymphs of four lotic environments in the central region of State of Rio Grande do Sul, a subtropical area in southern Brazil, were evaluated. Samplings were done monthly, with a Surber sampler, from June 2001 to May 2002, in the Jacuí River and three of its tributaries. The total number of nymphs collected in the four sampling sites was 11,007 in five families and 19 genera, of these, 11 are new records for the State. The highest diversity occurred in Point 4 (H'=2.41) and the lowest in Point 2 (H'=1.69). Point 4 had the highest environmental stability, conservation of the riparian vegetation and the lowest anthropic impact, while Point 2 presented a large environmental simplification... |

| The goal of this study was to investigate the effect of temperature on the life cycle of Acanthagrion nymphs sampled in a stream in the southern state of Amazonas. Altogether, 50 nymphs (10 in each of the five treatments) with ambient temperatures of 16, 20, 24, 28 and 32°C and water temperatures of 18, 22, 26, 30 and 34oC, respectively, were used. The only treatment that had a hatching adult was at a temperature of 28oC, identified in a single species, Acanthagrion apicale. In all other treatments (16, 20, 24 and 32oC), all nymphs died, respectively 1, 1, 3 and 2 days. We conclude from the results of this study that controlling water temperature near 28°C was the most efficient for obtaining adult A. apicale, and that this temperature was close to the... |

| Se evaluaron seis formulaciones comerciales de insecticidas para el control de los diferentes estados biológicos de Diaphorina citri (Kuwayama) en limón persa en condiciones de invernadero y en laboratorio. Los insecticidas estudiados fueron Imidacloprid + Betacyflutrin, Spirotetramat, Imidacloprid, Thiametoxam + Lambda cyalotrina, Imidacloprid + Lambda cyalotrina, Aceite parafínico de petróleo y un testigo sin aplicación. Se utilizaron especímenes de una cria de D. citri establecida en enero de 2012 sobre plantas de limón persa con más de un año de no tener aplicaciones de insecticidas. Los parámetros evaluados fueron toxicidad de los insecticidas en huevecillos, ninfas y adultos. Los ensayos se dispusieron en un diseño completamente al azar, con 10... |

| A key to the Brazilian genera of Ephemerelloidea, nymphs and adults, belonging to the families Coryphoridae, Leptohyphidae and Melanemerellidae is presented. Currently, seven genera of this superfamily are known in Brazil. The Leptohyphidae is the most representative family, with five genera registered from the country, Leptohyphes Eaton, 1882, Leptohyphodes Ulmer, 1920, Traverhyphes Molineri, 2001, Tricorythodes Ulmer, 1920 and Tricorythopsis Traver, 1958. The families Coryphoridae and Melanemerellidae are monotypic, represented by Coryphorus Peters, 1981and Melanemerella Ulmer, 1920. |

| Laboratory and greenhouse studies were conducted with an artificial dry diet to rear nymphs, and with an artificial plant as substrate for egg laying by the southern green stink bug, Nezara viridula (L.). The artificial diet was composed of: soybean protein (15 g); potato starch (7.5 g); dextrose (7.5 g); sucrose (2.5 g); cellulose (12.5 g); vitamin mixture (niacinamide 1 g, calcium pantothenate 1 g, thiamine 0.25 g, riboflavin 0.5 g, pyridoxine 0.25 g, folic acid 0.25 g, biotin 0.02 mL, vitamin B12 1 g - added to 1,000 mL of distilled water) (5.0 mL); soybean oil (20 mL); wheat germ (17.9 g); and water (30 mL). Nymphs showed normal feeding behavior when fed on the artificial diet. Nymphal development time was longer than or similar to that of nymphs fed... |

| The stonefly (Pleeoptera) nymphs of streams of the Almas River basin, Pirenópolis, Goiás State, Central Brazil, and some abiotie factors that might affect their temporal distribution were studied. Nymphs were sampled monthly (June 1993 to July 1994) in five stations with a Surber sampler, and each sample consisted of 20 units totalling 2 m². In each station, stream velocity, discharge, temperature, electrical conductivity and pH were measured in order to assess their influence on the density of nymphs. Nymphs were identified to genus level. In general, the annual variation in density of nymphs, in four stations, showed that the seasonal variation was not clearly influenced by the annual rain cycle. In the case of the one of the stations, where numbers of... |
