| 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... |

| ABSTRACT Some species of Cyclocephala Dejean, 1821 (Coleoptera, Scarabaeidae, Dynastinae, Cyclocephalini) were reported as crop or pasture pests. Within this genus, Cyclocephla tucumana Bréthes, 1904 was noticed in cultivated areas in South Brazil, 2009 − 2010. Other study found larvae of the species associated with pastures in Aquidauana, Mato Grasso do Sul State (MS), 2009. In the present study, larvae of C. tucumana were collected in pasture areas from August 2015 to July 2016, in Cassilândia, MS. The material was reared in laboratory for the description of immatures, and the regional population was studied to clarify its dynamics. Immatures were abundant throughout the years and are described for the first time. Taxonomic discussion, updated key to... |
