| Several coleopterans of the Scarabaeidae family (Pleurosticti) are reported as important pests of agricultural crops, but little information on their biology is available. We describe our observations on the biology of adult Cyclocephala verticalis Burmeister collected with light traps from January, 2006 to December, 2007, in Aquidauana, MS, Brasil. Field collected adults were taken to the laboratory and kept in plastic containers containing soil and seedlings of Brachiaria decumbens under controlled conditions (26 ± 1ºC with 12h of photophase). The embrionary period of C. verticalis took 17.2 days in the average. The duration of first-, second- and third-instar larvae was 22.0, 23.7 and 138.1 days in the average, respectively. The prepupal stage took 12.7... |

| Besouros dinastíneos foram coletados em Querari, Município de São Gabriel da Cachoeira, região do alto rio Negro, Estado do Amazonas, de abril a maio de 1993. Utilizaram-se lâmpadas de luz mista de mercúrio de 250 W, BL e BLB, sobre um lençol branco, em 33 noites de coletas de 12 horas consecutivas. Foram coletados 76 indivíduos de 20 espécies e 10 gêneros. A tribo Cyclocephalini foi a mais representada (10 espécies), seguida por Phileurini (4 spp.), Oryctini (3 spp.), Dynastini (2 spp.) e Pentodontini (1sp.). Dessas, 7 espécies são registradas pela primeira vez para o Amazonas, 5 delas para o Brasil. |

| The studies were conducted on the biological aspects of Cyclocephala tucumana Brethes, 1904 and C. melanocephala (Fabricius, 1775) in Aquidauana, MS, Brazil. From January to December 2009 a light trap was installed to make collections of adults of C. tucumana and from January 2010 to February 2011 for collections of adults of C. melanocephala, at the experimental farm of the Universidade Estadual de Mato Grosso do Sul. Adults were maintained in plastic containers with soil and complete plants of Brachiaria decumbens Stapf cv. Basilisk to oviposition and start biological studies. Adults of C. tucumana were collected from September to November in the field; the embryonic period lasted on average 14.7 days, and the first, second and third larval instars... |

| Besouros dinastíneos foram coletados no Parque Nacional do Jaú, Estado do Amazonas, entre julho de 1993 a junho 1996, em dias de Lua minguante e nova, em 5 localidades diferentes, abrangendo principalmente a região dos baixos cursos dos rios Jaú, Carabinani e Unini. Utilizou-se para as coletas luz mista de mercúrio de 250 W e duas lâmpadas ultra-violeta, black-light (BL) e black-light blue (BLB), sobre um lençol branco em períodos diários de 12 horas consecutivas. Foram identificadas 34 espécies de 14 gêneros, sendo as espécies da tribo Cyclocephalini as mais representadas (19 espécies), seguidas por Oryetini (6 spp.), Phileurini (4 spp.), Pentodontini (3 spp.) e Dynastini com 2 espécies. |

| Foram efetuadas coletas mensais de julho/1990 a junho/1991, durante a lua nova, na Fazenda Aruanã, uma área de terra-firme às margens da rodovia Torquato Tapajós, AM-010, Km 215, Município de Itacoatiara, Estado do Amazonas, Brasil. Utilizou-se para as coletas luz mista de mercúrio de 250 W, sobre um lençol branco. Foram coletados 251 indivíduos de 9 gêneros e 18 espécies de dinastíneos e dentre estes houve predominância de Cyclocephala Latreille (3 espécies abundantes) e Ligyrus Burmeister (única espécie abundante). |

| The genus Coelosis with two subgenera, Coelosis s.str. [type species: Scarabaeus sylvanus Fabricius, 1775] and Eucoelosis subgen.n. [type species: Scarabaeus biloba Linnaeus, 1767], is revised and redescribed. Other four species: C. (C.) inermis Sternberg, 1908, C. (C.) bourgini (Dechambre, 1976), C. (Eucoelosis) hippocrates Blanchard, 1846, and C. (E.) bicornis (Leske, 1779) were recognized and redescribed. Coelosis (E.) denticornis Arrow, 1937 was not studied, and the original description is transcribed herein. New characters considered relevant for comparative studies and for species identification are presented. The subgenus Millotsis Bourgin, 1944 [type species: Coelosis inermis Sternberg, 1908] is considered a junior subjective synonym of Coelosis... |

| Coleoptera of the family Melolonthidae plays an important role in decomposition and nutrient recycling in the environment, however the information of this group is scarce in Brazil; therefore studies were developed with the objective of understanding the biological aspects of saproxylophagous. The studies were developed in the experimental farm of the State University of Mato Grosso do Sul, in Aquidauana, from March 2011 to April 2012. In a forest fragment of the cerrado, when encountering fallen tree trunks, they were cut into small pieces for extraction and acquisition of immature and adult Melolonthidae. Larvae were taken to the laboratory where they were reared until emergence of adults, obtaining biological and biometric data. A total of 145 larvae... |

| ABSTRACT: Cyclocephala flavipennis Arrow, 1914 (Coleoptera: Melolonthidae), popularly known as white grub, is an insect widely disseminated in the South Region of Brazil. Despite the frequent occurrence of this white grub in areas cultivated with winter cereals, it is generally not considered a pest, since it feeds on straw and dead plant material. However, in 2015 and 2016, this insect has been identified as the damage-causing agent in the perennial winter pastures in Lages, Santa Catarina, Brazil. Damage was observed in patches and caused reduction in root depth and mass, resulting in loss of vigor, accelerated senescence in aerial parts, and death of tillers in Festuca arundinacea Schreb. and Dactylis glomerata L. plants. |
