| 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... |

| 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... |
