Resumo. O gênero Cyclocephala possui grande quantidade de espécies distribuídas nas várias regiões do Brasil, entretanto, poucos são os estudos relacionados ao comportamento de cópula, assim o presente trabalho teve como objetivo estudar o comportamento de cópula de Cyclocephala verticalis Burmeister. Com uma armadilha luminosa instalada ao lado de área de pastagens, foram realizadas coletas de adultos de agosto a setembro de 2013. Em laboratório machos e fêmeas foram mantidos em recipientes separados e ao anoitecer, foram formados casais para observações das etapas que envolvem o comportamento de cópula. De 28 de outubro a 4 de novembro de 2013, para determinar o horário de voo, recolheu-se os insetos coletados na armadilha luminosa a cada 60 min, iniciando os estudos as 18:00 h e encerrando as observações as 6:00 h do dia seguinte. Ao saírem do solo os adultos realizaram ativamente o voo, em seguida pousaram, e o macho ao localizar a fêmea, se aproxima e a toca com o primeiro par de pernas e antenas. Se a fêmea aceita o macho, ocorre à cópula a qual durou 12,5 + 1,3 min em média, e ocorreu entre 19:00 h e 02:00 h. Em algumas ocasiões as fêmeas não aceitaram os machos para a cópula, indicando que os estes provavelmente não estavam aptos a se reproduzirem, ou a própria fêmea não estava apta a se reproduzir, havendo nesse momento reconhecimento químico entre os adultos para a formação do casal. Os adultos revoaram em campo em maiores quantidades das 20:00 h as 23:00 h. Palavras-Chave:Atividade de voo; Comunicação química; Cyclocephalini; Dynastinae; Scarabaeoidea. Mating Behavior in Cyclocephala verticalis Burmeister (Coleoptera: Scarabaeidae)Abstract. The genus Cyclocephala has a large number of species distributed in various regions of Brazil, however, there are few studies related to mating behavior of this group, so this paper was to study the behavior of copulation Cyclocephala verticalis Burmeister.

“…The complete ontogenic cycle of C. paraguayensis is 171 ± 11 days long (n = 7), similar to C. celata (≈164 days; Souza et al 2013 ), but comparatively shorter than C. verticalis (≈228 days; Rodrigues et al 2010 ) and C. forsteri (≈257 days; Coutinho et al 2011 ). …”

“…As such, in most tropical ecosystems, the unambiguous identification of larvae is hampered and pest management plans cannot be safely implemented ( Ramirez-Salinas et al 2004 ). Exceptions include C. lurida Bland (previously referred to as C immaculata Olivier), C. longula (senior synonym of C.abrupta), C. borealis, and C. pasadenae ( Ritcher 1966 ); C. signaticollis Burmeister ( Morelli 1991 ; Mondino et al 1997 ); C. testacea Burmeister ( Morelli and Auzugaray 1994 ); C. fulgurata Burmeister, C lunulata Burmeister, and C. gregaria Heney & Thaschenberg ( Bran et al 2006 ); C. forsteri Endrödi ( Santos and Ávila 2007 ; Oliveira and Ávila 2011 ); C comata (Bates) ( García et al 2009 ); C verticalis Burmeister ( Rodrigues et al 2010 ; Coutinho et al 2011 ); and C. celata ( Souza et al 2013 ). …”

In order to obtain information on the biology of the masked chafer, Cyclocephala paraguayensis Arrow (Scarabaeidae: Dynastinae: Cyclocephalini), and its immature morphology, the beetle life cycle was studied under laboratory conditions. After field collection, adults were placed inside containers filled with soil obtained in the original capture to provide an oviposition site after mating ocurred. Eggs were collected daily and isolated for manipulation experiments and life cycle observations. Detailed information about the eggs, instars and life cycle duration, and morphological features of immature stages were noted and examined. Egg viability was higher in the “non-manipulated” batch. The complete ontogenic cycle of C. paraguayensis was 171 ± 11 days (n = 7). Despite the records of Cyclocephala being crop pests, reared larvae of C. paraguayensis thrived and developed into well-formed, fertile adults on an entirely saprophagous diet, indicating that they are not rhizophagous in the wild. The third instar can be distinguished from the other species mainly by the following unique characters: maximum width of the head capsule, distal antennal setae, and bifurcated setae on the raster.
