1. A crop pest species of Cyclocephala Dejean (Coleoptera: Melolonthidae: Dynastinae) misidentified for over twenty years in Southern Brazil
ABSTRACT A common white grub species associated with a wide range of crops in Southern Brazil has been named as Cyclocephala flavipennis Arrow for over twenty years. This work aimed to revise the identity of this species based on the study of primary types, identified material collected in previous works and descriptions on literature. The confirmed name for

2. Population dynamics and description of larva and pupa of Cyclocephala tucumana Bréthes, 1904 in West-Central Brazil, and remarks on immatures of other Cyclocephala species (Coleoptera: Scarabaeidae: Dynastinae)
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

3. Description of the third instar larva of Saccharoscaptus laminifer (Dechambre) (Coleoptera: Melolonthidae: Dynastinae)
Abstract The larva of pentodontine S. laminifer is described for first time based on specimens collected under roots of sugarcane in Santa Cruz, Bolivia. Diagnostic structures are illustrated and the differences and similarities with other previously described larvae of South American genera of Pentodontini are outlined. A key to the larvae of some American

7. First report of two species of scarab beetles (Coleoptera, Scarabaeidae) inside nests of Azteca cf. chartifex Forel (Hymenoptera, Formicidae) in Brazilian Amazonian Rainforest
ABSTRACT We report for the first time the occurrence of two species of scarab beetles, Phileurus carinatus declivis Prell, 1914 (Scarabaeidae: Dynastinae) and Cyclidius elongatus (Olivier, 1789) (Cetoniinae: Cremastocheilini) inside nests of Azteca cf. chartifex Forel, 1896, a neotropical arboreal ant species. This report indicates that these two beetle spec

8. Flight patterns and sex ratio of beetles of the subfamily Dynastinae (Coleoptera, Melolonthidae)
ABSTRACT Dynastinae is one of the most representative subfamilies of Melolonthidae (Scarabaeoidea) and has considerable ecological importance due mainly to interactions with plants of the families Araceae and Annonaceae. This relationship has led to the evolution of nocturnal activity patterns, which are influenced by environmental conditions. In the present

9. Biology and management of the masked chafer Cyclocephala distincta Burmeister (Melolonthidae, Dynastinae, Cyclocephalini)
Adults of Cyclocephala distincta are flower visitors of Neotropical palms (Arecaceae) and commonly found in the Atlantic Forest of Pernambuco, Brazil. Males and females were collected in the wild and subjected to captive rearing and breeding. The egg hatching rate, the life cycle, longevity of immatures and adults, and oviposition parameters in captivity wer

11. Polinização e biologia reprodutiva de Araticum-liso (Annona coriacea Mart.: Annonaceae) em uma área de cerrado paulista: implicações para fruticultura
Anonáceas, em geral, são espécies cantarófilas e altamente especializadas, apresentando pétalas espessas, carnosas e nutritivas que formam uma câmara floral com ocorrência de termogênege. Este estudo objetivou verificar os efetivos polinizadores e sistema reprodutivo prevalente em A. coriacea. Flores foram marcadas e acompanhadas durante períodos do

12. A evolução da biologia reprodutiva de Annonaceae
As flores de Annonaceae são caraterizadas por pétalas carnosas, muitos estames com conectivos duros em forma de escudo e numerosos carpelos com estigmas sésseis que produzem exsudados pegajosos. As pétalas de muitas espécies formam uma câmara de polinização durante a antese. Protoginia e fortes emissões de cheiro, especialmente durante a fase femini
