A Crispy Delicacy: Augosoma Beetle as Alternative Source of Protein in East Cameroon

F. J. Muafor, P. Levang, and P. Le Gall

Résumé :

Despite the fact that the exoskeleton of the Augosoma centaurus (Dynastinae) is hard and difficult to chew, this insect is often gathered in Eastern Cameroon for food in periods of availability. Nine ethnic groups in Eastern Cameroon were surveyed to understand the role of this insect in assuring food security, using quantitative and qualitative social science approaches. Both the larvae and adult stages of this beetle are habitually consumed in the areas studied. In total, about 65% of consumers prefer consuming the adults, while 35% prefer consuming the larvae. About 24% of consumers derive the same satisfaction from the consumption of Augosoma or other edible insects. Close to 39% of consumers prefer other edible insects to Augosoma, while 37%prefer the consumption of Augosoma to other edible insects. This beetle usually occurs at a period when other edible insects are not available, therefore constituting a good source of alternative protein in this region where poverty, poaching, and biodiversity erosion are still a major problem. Furthermore, the gathering of this beetle for food is equally a means of biological pest control of raffia plants and a tool to enhance community-based conservation of the areas global biodiversity.

A Review of the South American Genus Hoplopygothrix Schurhoff (Coleoptera: Scarabaeidae: Cetoniinae: Gymnetini)

Brett C. Ratcliffe 

Résumé :

The southern Brazilian genus Hoplopygothrix is reviewed. The genus now contains only one species, H. atropurpurea (Schaum). Hoplopygothrix atropurpurea nigroscutellaris (Moser) and H. fulvohirta (Moser) are placed in synonymy with H. atropurpurea.

Biodiversité des insectes de la ligne volcanique du Cameroun: distribution altitudinale d’une famille de Coléoptères

Fogoh John Muafor, Tsi Evaristus Angwafo & Philippe Le Gall

Résumé :

Les écosystèmes montagnards tropicaux sont très riches en espèces endémiques, menacées par les activités anthropiques et les changements globaux. Nous avons échantillonné un total de124 espèces de Cetoniinae de la Ligne Volcanique du Cameroun durant la période de 2007 à 2010. Les données ont été analysées en utilisant le logiciel PAST. Le massif volcanique du Mont Manenguba s'est révélé être le plus riche des massifs (Menhinick=3.18). On observe un étagement précis des communautés, la faune endémique de la LVC étant concentrée dans les régions d’altitude supérieure à 1600 m.

Hoplopygothrix Schürhoff (Coleoptera: Scarabaeidae: Cetoniinae: Gymnetini) Revisited: a New Species and Country Record for Bolivia

Brett C. Ratcliffe 

Résumé :

The southern South American genus Hoplopygothrix Schürhoff is augmented with the description of a new species from Bolivia. The genus now contains two species, Hoplopygothrix atropurpurea (Schaum) and Hoplopygothrix boliviensis Ratcliffe, new species. Illustrations accompany the description, and a key is provided to identify the species.

WEST CENTRAL AFRICAN PEOPLES: SURVEY OF RADIOCARBON DATES OVER THE PAST 5000 YEARS

Richard Oslisly• Ilham Bentaleb• Charly Favier• Michel Fontugne• Jean François Gillet•Julie Morin-Rivat

Résumé :

Tracing human history in west central Africa suffers from a scarcity of historical data and archaeological remains. In order to provide new insight into this problem, we reviewed 733 radiocarbon dates of archaeological sites from the end of the Late Stone Age, Neolithic Stage, and Early and Late Iron Age in Cameroon, Gabon, Central African Republic, Equatorial Guinea, Republic of Congo, and the western Democratic Republic of Congo. This review provides a spatiotemporal framework of human settlement in the forest biome. Beyond the well-known initial spread of Iron Age populations through central African forests from 2500 cal BP, it depicts the geographical patterns and links with the cultural evolution of the successive phases of human expansion from 5000 to 3000 cal BP and then from 3000 to 1600 cal BP, of the hinterland depopulation from 1350 to 860 cal BP, and of recolonization up to 500 cal BP.

Oplostomus Fuligineus (Coleoptera: scarabaeidae): life cycle and biology under laboratory conditions, and its occurrence in bee hives.

Jean M. I. Donaldson

Résumé :

Oplostomus fuligineus Olivier (Cetoniinae : Cremastocheilini) has been known as a pest in bee hives in southern Africa since the early 1900’s. This is the first description of its life cycle and breeding habits. Eggs were laid in a mixture of soil and cattle dung and took 6 to 10 days (mean 7.9 days) to hatch. The larvae (description is given) were fed on a mixture of soil, compost and cattle dung in the ratio of 1:2:3 by volume and took 30 to 38 days (mean 33 days) to become pupae. The pupae took 21 to 29 days (mean 25 days) to eclosion. Survival rate of eggs was 95%, larvae 61% and pupae 71%. Female and male adults could be distinguished by the shape of the abdominal sternites. They fed preferentially on open bee brood containing larvae, also on young capped brood and survived well on pollen and honey. In nature they seldom feed on flowers as do other Cetoniinae.

A Revision of the Neotropical Genus Desicasta Thomson (Coleoptera: Scarabaeidae: Cetoniinae: Gymnetini)

Brett C. Ratcliffe 

Résumé :

The genus Desicasta Thomson, 1878 is comprehensively reviewed, and the formerly eight species are reduced to three. Redescriptions of previously known species, a key for identification, and illustrations of the three species are provided. Desicasta sculptilis Thomson, 1878, Moscheuma sebosum Neervoort van de Poll, 1886, and Moscheuma opaca Kraatz, 1898 are placed as new junior synonyms of Desicasta lobata (Olivier, 1789). Desicasta laevicostata (Neervoort van de Poll, 1886) is a new junior synonym of Desicasta reichei (Thomson, 1860). Desicasta nonfriedi Schoch, 1896 is a new junior synonym of Amithao erythropus (Burmeister, 1842).

Seasonal and altitudinal structure of drosophilid communities on Mt Oku (Cameroon volcanic line)

Stéphane R. Prigent, Philippe Le Gall, Shay Wilfred Mbundae, Michel Veuille

Résumé :

We assessed the potential of drosophilids as indicators of the response of  tropical ecosystems to climatic factors over an annual cycle in the montane forest of Mt Oku, by collecting samples at seven sites evenly spaced from 2200 m to 2800 m asl. Only 0.1% of the 11,000 specimens collected belonged to invading species or those commensal with humans, showing the weakness of anthropogenic factors. Species abundance was highly skewed. One species, Zaprionus vittiger, made up 81% of the sample, whereas 42 of the 62 morphological species found were represented by fewer than 20 individuals. Many of the most abundant species occurred over  a  narrow  period,  in  the  dry  or  in  the  rainy  season, others  also  occurred  at  intervening  periods.  These  different  patterns  of  population dynamics,  determined  a  succession  of  species  over  the  annual  cycle.  Abundant  species departed  significantly  from  each  other  in  their  distribution  over  collection  sites.  The drosophilid  populations  from  the  central  African  montane  forests  are  highly  dependent  on climatic  factors, either  directly, or indirectly through climatic effects on the bioticenvironment of  the  insects.
