Population studies of grass grub and black beetle have revealed simple patterns of population determination. Populations fluctuate in response to variations in soil moisture and temperature. The upper limit to population growth is set by density dependent factors (larval mortality of grass grub and variation in natality of black beetle). Parasites and predators appear to be generally unimportan...

The Afrotropical Region is the center of the diversity of the scarab beetle genus Orphnus MacLeay, 1819 (Coleoptera: Scarabaeidae: Orphninae), with 94 species occurring from Sahel in the north to Little Karoo in the south (Paulian, 1948; Petrovitz, 1971; Frolov, 2008). The East African Rift is one of the richest regions of the Afrotropics housing more than 20 species of Orphnus (Paulian, 1948; ...

Pentodontini is the most diverse tribe of Dynastinae (Coleoptera: Scarabaeidae), and most of the genera are restricted to a single biogeographic region. In this work, the taxonomic composition of the Pentodontini in Colombia was determined, and genera and species were diagnosed based on external morphology and male genitalia. Records of 1,580 specimens from 31 departments and 398 localities in ...

Hemicyrthus blaffarti new species (Coleoptera: Scarabaeidae: Dynastinae) from the Parc Provincial de la Rivière Bleue in southern New Caledonia is described. It differs from the most similar species, H. elongatus, by the completely and sharply margined pronotal base, the presence of elytral micropunctures, shorter apical setae of the mesotibiae and meta-tibiae, and a different shape of the para...

Bu çalışma, Türkiye-Ankara ili Kazan ve Çubuk ilçeleri arasında bulunan, önemli doğa koruma alanı olan, tepelerinin Scarabaeidae faunasının belirlenmesini amaçlamıştır. Altı farklı alanda, zamanlarda kurulmuş çukur tuzaklarına yakalanan örnekler incelenmiştir. Tuzaklardan 4 altfamilyaya ait 50 tür alt seviyesinde takson tespit edilmiştir. Belirlenen türlerin Türkiye dağılışları verilmiştir. Çal...
