Contribution à l’étude de la biodiversité des coleoptères tenebrionidae de la République du Bénin: premier inventaire

Gérard Robiche, Philippe Le Gall et Georg Goergen

Résumé :

Un inventaire faunistique des coléoptères Tenebrionidae a été conduit en République du Bénin Durant plusieurs années. Cette famille était restée jusqu’ici relativement peu étudiée pour la zone géographique considérée. Les récoltes effectuées dans diverses localités représentatives des zones phytogéographiques ont permis de recenser, à ce jour, 197 espèces, dont 5 nouvelles et d’apporter quelques renseignements biologiques et écologiques sur certaines d’entre-elles. Près de la moitié des espèces répertoriées sont illustrées. Les espèces Argobrachium barrei sp. n., Oncosoma girardi sp. n. et Strongylium beniniensis sp. n. sont nouvellement décrites.

Contribution à la systématique du genre Aethiessa Burmeister, 1842 (Coleoptera: Cetoniidae: Cetoniinae)

Moreno DUTTO & Denis KEITH

Résumé :

Major inconsistencies between the currently used taxonomy and the type material were noticed during the revision of some types of the Cetoniidae family. In this study, we clarify the taxonomic position of Aethiessa inhumata and designate a lectotype. Likewise, we also designate a lectotype of A. floralis, the type-species of the genus.

Interaction entre le système de culture et le statut (ravageur ou auxiliaire) des vers blancs (Coleoptera : Scarabeoidea) sur le riz pluvial

Alain Ratnadass et al.

Résumé :

A Madagascar, les larves et adultes terricoles de certaines espèces de Coléoptères Scarabeoidea causent d’importants dégâts au riz pluvial. Le traitement insecticide des semences assure une protection efficace, mais son impact environnemental soupçonne justifie des recherches pour s’en affranchir, notamment en systèmes de culture avec semis direct sur couverture végétale (SCV). Un système SCV, fondé sur une rotation riz pluvial soja depuis 1998-1999, a ainsi été étudié de 2002 à 2007 sur deux sites des Hautes Terres. Sur cette rotation, on a trouvé, au bout de quatre ans (en 2002-2003), un effet positif du SCV (par rapport au labour) et du traitement de semences, en termes de réduction des attaques de ravageurs et de rendement du riz pluvial, sans effets négatifs du traitement des semences sur la biodiversité de la faune tellurique. Les quatre années suivantes, l’abondance de la macrofaune (phytophages comme saprophages/géophages et prédateurs), a augmenté, en particulier en SCV, sans que cela se traduise par des effets notables sur les rendements en 2005 et 2007. On a également étudié en laboratoire les préférences alimentaires des larves (« vers blancs ») de 3 espèces appartenant chacune à une famille de Scarabeoidea, et la variation du statut des larves de 7 espèces dans ces trois familles, en fonction du contenu du sol en matière organique. Bricoptis variolosa (Cetoniidae) et Hexodon unicolor (Dynastidae) se sont révélées être saprophages obligatoires, alors que Apicencya waterloti (Melolonthidae) s’est revélé rhizophage obligatoire, tandis que Heteroconus paradoxus et 3 autres espèces de Dynastidae (Heteronychus plebeius, H. bituberculatuset H. arator rugifrons) se sont révélés rhizophages facultatifs. Outre les changements dans la composition faunistique tellurique induits par la gestion SCV, le changement de statut de certains vers blancs selon le statut organique du sol ouvre de nouvelles perspectives de gestion des agroécosystèmes rizicoles pluviaux.

Phylogeography and population genetics of the maize stalk borer Busseola fusca (Lepidoptera, Noctuidae) in sub-Saharan Africa

Sézonlin et al

Résumé :

The population genetics and phylogeography of African phytophagous insects have received little attention. Some, such as the maize stalk borer Busseola fusca, display significant geographic differences in ecological preferences that may be congruent with patterns of molecular variation. To test this, we collected 307 individuals of this species from maize and cultivated sorghum at 52 localities in West, Central and East Africa during the growing season. For all collected individuals, we sequenced a fragment of the mitochondrial cytochrome b. We tested hypotheses concerning the history and demographic structure of this species. Phylogenetic analyses and nested clade phylogeographic analyses (NCPA) separated the populations into three mitochondrial clades, one from West Africa, and two — Kenya I and Kenya II — from East and Central Africa. The similar nucleotide divergence between clades and nucleotide diversity within clades suggest that they became isolated at about the same time in three different refuges in sub-Saharan Africa and have similar demographic histories. The results of mismatch distribution analyses were consistent with the demographic expansion of these clades. Analysis of molecular variance (AMOVA) indicated a high level of geographic differentiation at different hierarchical levels. NCPA suggested that the observed distribution of haplotypes at several hierarchical levels within the three major clades is best accounted for by restricted gene flow with isolation by distance. The domestication of sorghum and the introduction of maize in Africa had no visible effect on the geographic patterns observed in the B. fuscamitochondrial genome.

Fauna of the Cetoniid Beetles (Coleoptera: Cetoniidae) and their Damages on Peach Fruits in Orchards of Northern Dalmatia, Croatia

Josip RAZOV et al

Résumé :

The beetles Cetonia aurata and Potosia cuprea belonging to the subfamily Cetoniinae (Coleoptera: Cetoniidae) are present in peach orchards in Northern Dalmatia, Ravni kotari region. They are often described as flower pest (“Rose chafers, flower beetles”), and are thought not to be significant as fruit pests. However, during the last ten years some serious damage to fruit has been observed. Since this damage occurs when the fruits are ripening, insecticides cannot be used. There are no literature data about the amount of the damage or how to monitor the damage. This paper describes our monitoring of the population dynamics of the Cetonia aurata and Potosia cuprea, and the method for calculating the damage to fruit suitable for the orchards in this area. The study was conducted during the spring and summer of the year 2005, 2006 and 2007 in the Ravni kotari region, near the villages of Prkos and Smilčić. We used Csalomon® VARb3k funnel traps. We took into consideration the population dynamics of the Cetonia aurata and Potosia cuprea, the determination of the other trapped members of the subfamily Cetoniinae, as well as the damage percentage of each cultivar.

Phylogeographic pattern and regional evolutionary history of the maize stalk borer Busseola fusca(Fuller) (Lepidoptera: Noctuidae) in sub-Saharan Africa

Sezonlin et al

Résumé :

Busseola fusca (Fuller) (Lepidoptera: Noctuidae) is one of the major cereal pests in subSaharan Africa. Previous phylogeographic investigations on samples collected in Kenya, Cameroon and West-Africa showed the presence of three main clades (W, KI, KII) originated from populations isolated in West and East Africa around one million years ago. Demographic and phylogenetic analyses suggested that this event was followed by local demographic expansion and isolation by distance. These hypotheses were tested by a more comprehensive sampling across B. fusca’s geographic range in Africa. Comparisons of sequences of partial mitochondrial DNA gene (cytochrome b) from 489 individuals of 98 localities in southern, central, eastern and western African countries confirmed the presence of the three main clades. Phylogenetic, F-statistics, demographic parameters and nested clade phylogeographic analyses confirmed that the clades experienced geographic and demographic expansion with isolation by distance after their isolation in three refuge areas. The geographic range of clade KII, already known from East to Central sub-Saharan Africa was extended to Southern Africa. Mismatch distribution analysis and the negative values of Tajima’s D index are consistent with a demographic expansion hypothesis for these three clades. Significant genetic differentiations were revealed at various hierarchical levels by analysis of molecular variance (AMOVA). Hypotheses about the geographic origin of the three main clades are detailed.
