Aspectos biológicos de Cyclocephala verticalis burmeister (coleoptera: scarabaeidae)

New Species of CyclocephalaDejean, 1821 from Guatemala (Scarabaeidae: Dynastinae: Cyclocephalini)

“…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).…”

“…These are referred to as "non-manipulated." We have documented the following information for both batches during egg development: date and mode of oviposition, egg coloration, egg shape, date of larval eclosion, and egg viability, the latter following the method described by Rodrigues et al (2010).…”

“…Females oviposited at the bottom of the containers, and the eggs were laid individually. As has been described for several species of dynastine scarabs and other Cy-clocephala, the females of C. paraguayensis protect their new eggs within a spherical clump of soil called the egg chamber (Rodrigues et al 2010). Newly laid eggs have a thin membrane, and are consequently prone to dessication and abruption; the egg chamber provides extra protection (Potter and Gordon 1984).…”

“…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).…”

Occurrence of adults and biological aspects of Geniates borelli Camerano (Coleoptera, Scarabaeidae, Rutelinae) in Aquidauana, MS, Brazil

“…In the subfamily Dynastinae, biological studies have been conducted for Diloboderus abderus Sturm, 1826 , Cyclocephala forsteri Endrodi, 1963 (Santos & Ávila 2007), Cyclocephala verticalis Burmeister, 1847 (Rodrigues et al 2010a) and Aegopsis bolboceridus (Thomson, 1860) (Oliveira et al 2008). …”
