African dung beetle Onthophagus gazella Fabricius (Coleoptera: Scarabaeidae) esterase isozymes.
African beetles Onthophagus gazella from both sexes were analyzed by electrophoresis for an investigation of esterase isozymes using alpha-naphthyl propionate and methylumbelliferyl propionate as substrates. Only one of the esterases (Est. 6) reacted with one of the substrates (alpha-naphthyl propionate). Six areas of activity were found, two of them being polymorphic (Est. 3 and Est. 4). For p...
متن کاملA 'metaphising' dung beetle.
You may have seen the film Microcosmos, produced in 1996 by the French biologists Claude Nuridsany and Marie Perrenou. It does not star humans, but much smaller creatures, mostly insects. The filmmakers’ magnifying camera transposes the viewer into the world of these organisms. For me, Microcosmos is not an ordinary naturalist documentary; it is an exercise in metaphysics. One sequence in the f...
متن کاملNew evidence for the validity of Coprophanaeus (C.) terrali Arnaud, 2002 (Coleoptera: Scarabaeidae: Scarabaeinae: Phanaeini), a dung beetle from Brazil.
Coprophanaeus terrali, a species based on a single male from Sinop, Brazil, had its validity questioned recently when it was suggested that its tetratuberculate cephalic carina could be just an individual variation of C. dardanus (MacLeay, 1819). In this work, based on three additional males and two females collected near the type locality, we present new evidence supporting the validity of thi...
متن کاملCopelatus cessaima sp. nov. (Coleoptera: Dytiscidae: Copelatinae): first record of a troglomorphic diving beetle from Brazil.
Copelatus cessaima sp. nov. is described from Brazil. The new species was collected in water puddles inside of caves found in an ironstone formation and has typical troglomorphic characters: the eyes and metathoracic wings are absent, the elytra are fused and the body has long setae. This is the second species of Copelatinae reported as troglomorphic and the first record of a troglomorphic Dyti...
متن کاملA new cytological record of two scarab beetle species from the genus Gymnopleurus Illiger, 1803 (Coleoptera: Scarabaeidae)
Karyological investigations on two Gymnopleurus spp.; Gymnopleurus miliaris (F.) and Gymnopleurus parvus (MacL.) are under taken in the present study. Meioformula of G. miliaris (17AA+Xyp) and G. parvus (8AA+Xyp) are presented. None of these beetles exhibited a modal polyphagan karyotype. However, Xyp was found to be the male sex chromosome mechanism. Most chromosomes are acro and subtelocentri...
