Biology and New Larval Descriptions for Three Cetoniine Beetles (Coleoptera: Scarabaeidae: Cetoniinae: Cetoniini: Cetoniina, Leucocelina)


Résumé :

The larval morphology of Tropinota squalida (Scopoli) and Aethiessa floralis (Fabricius) is described. The latter is the first description of a larva in this genus. The third-instar larva of Oxythyrea funesta (Poda) is redescribed. These species are included in a revised key to the larvae of Palaearctic Cetoniinae. The life cycle and larval biology of these flower chafers are described.

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.

Using Floral Baited Colour Traps for Detection and Seasonal Monitoring of Oxythyrea funesta (Poda) (Coleoptera: Cetoniidae) in Bulgaria

Mitko Subchev et al

Résumé :

A new tool for detection and seasonal monitoring of Oxythyrea funesta(Poda), floral baited colour traps, a commercial product of Plant Protection Institute, Center for Agricultural Research, HAS, Budapest, Hungary, was used for studying the distribution and patterns of seasonal appearance of the pest in eight sites in Bulgaria in 2009 and 2010. The most numerous catches of O. funesta were recorded in Plovdiv in both years and in Troyan in 2010. Catches ranging from 21 to 52 beetles were recorded also in Dryanovo, Karnobat, Kyustendil, Petrich and Troyan in 2009; Knezha and Troyan in 2010. In 2009 the earliest catches of O. funesta were recorded in Petrich for the period April 12 – April 20. In 2010 the first catches were recorded in Knezha for the period April 16 – April 22. The latest catches for the two years were recorded on September 6, 2010 in Troyan. The traps showed low selectivity especially in sites where another cetoniid pest, Tropinota (Epicometes) hirta(Poda), attracted to the same traps, occurred.

Larval morphology and biology of four Netocia and Potosia species (Coleoptera: Scarabaeoidea: Cetoniidae: Cetoniinae)

Estefania Mico and Eduardo Galante

Résumé :

The larvae of Netocia morio (Fabricius, 1781), Netocia oblonga (Gory & Percheron, 1833), Potosia opaca (Fabricius, 1787) and Potosia cuprea brancoi Baraud 1992 are described. Comparison of the morphology of both genera revealed important differences in raster structure, mandibles and frontal setae. The systematic position of both genera based on larval characteristics is discussed. Some aspects of larval biology are discussed.

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.

Larval morphology enhances phylogenetic reconstruction in Cetoniidae (Coleoptera: Scarabaeoidea) and allows the interpretation of the evolution of larval feeding habits

Estefania Mico, Miguel Angel Moron, Petr Sipek and Eduardo Galante

Résumé :

The Cetoniidae, the showiest of scarabs, comprises some 3900 species in 515 genera, distributed worldwide except for subpolar areas and some offshore. New Zealand islands. Parsimony analysis of 76 larval and adult characters and 42 terminal taxa supports the monophyly of Cetoniidae (sensu Krikken, 1984), but not of the traditionally considered subfamilies Cetoniinae and Trichiinae (sensu Krikken, 1984). In the study taxon, larval characters are shown to be more informative than those of adults for deeper phylogeny. The evolution of some larval characters (head and legs) in relation to feeding habits is discussed on the basis of phylogenetic analysis. The results show an evolutionary shift from wood associations to a higher ecological plasticity that allows the larvae to feed on wide sources of organic matter (including compost, dung, gopher burrows, packrat middens, ant debris piles, etc.).

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.

Action of the saproxylic scarab larva Cetonia aurataeformis (Coleoptera: Scarabaeoidea: Cetoniidae) on woody substrates

E. Micó, M. Juárez, A.Sánchez and E. Galante

Résumé :

The saproxylic beetle Cetonia aurataeformis Curti (Scarabaeoidea: Cetoniidae) is a common Iberian species, whose larvae develop in tree cavities feeding on wood and litter. The aim of this paper is to analyse how the larvae of this cetonid modify the woody substrate by feeding and what the ecological implications on their microhabitat could be. Thermal analysis and infrared spectroscopy have been used to study the changes suffered by different substrates, litter and wood of Betula alba and Quercus pyrenaica, after digestion by the larvae. Results show that larvae of C. aurataeformis are able to digest polysaccharides and lignin producing a residue richer in nutrients than the original substrate and with an organic structure that contains a fraction of lignin that is easier to decompose. The main conclusion is that the action of cetonid larvae on woody substrates could facilitate their use by other saproxylic organisms in natural ecosystems.
