Hoverflies are among the most important insect pollinators and there is documented evidence of a recent decline in their populations. To trace the past distributions of hoverfly species, verified records of historical collections are essential.
Here, we provide data on 1071 specimens of hoverflies collected or received by Jean Timon-David and hoste...
A specimen of Microrhagus pyrenaeus Bonvouloir, 1872 (Coleoptera, Eucnemidae) was trapped in Fos-sur-Mer in 2012. It appeared in a recent publication under the name Eucnemis capucina Ahrens, 1812. M. pyrenaeus is new to the Bouches-du-Rhône department and also to Provence-Alpes-Côte-d'Azur region. This species, which as a high national heritage val...

Many insect species have shown dramatic declines over the last decades, as a result of man-related environmental changes. Many species which were formerly widespread are now rare. To document this trend with evidence, old records of collected specimens are vital.
We provide here the data on 9752 bee (Hymenoptera: Apoidea) specimens hosted in severa...
A targeted dung-beetle (Scarabaeoidea: Aphodiidae, Scarabaeidae & Geotrupidae) survey in the "mas de Gonon" sector (Fos-sur-Mer, Bouches-du-Rhône) was conducted in 2019. The present study raised the previous known species richness of this area from 6 to 31 dung beetles. The results shows a remarkable richness and includes species that are localized...

Pollinators are declining globally, with climate change implicated as an important driver. Climate change can induce phenological shifts and reduce floral resources for pollinators, but little is known about its effects on floral attractiveness and how this might cascade to affect pollinators, pollination functions and plant fitness.
We used an in...

A biography of Olivier Violo (1967-2017) artist and amateur entomologist is given
The introduction of mammals on oceanic islands currently threatens or has caused the extinction of many endemic species. Cats and rats represent the major threat for 40 % of currently endangered island bird species. Direct (predation) and/or indirect (exploitative competition for food resource) trophic interactions are key mechanisms by which invad...

Background
Black rats Rattus rattus and mat-forming iceplants, Carpobrotus aff. acinaciformis and Carpobrotus edulis are pervasive pests on Mediterranean islands. Their cumulative impacts on native biotas alter the functioning of island ecosystems and threaten biodiversity. We report here the first attempt to eradicate both taxa from a protected na...

Transmission blocking immunity (TBI) was studied in relation to age, gametocyte density and transmission intensity. subjects with high gametocytaemias were selected in a hypo-endemic urban district and a hyper-endemic rural area in South Cameroon. TBI was determined in blood from gametocyte carriers in a bioassay (Direct Membrane Feeding Assay), wi...
Ecology and biogeography of Phryneta bicoloripennis Breuning, 1965, endemic species from West Cameroonian Dorsal (Coleoptera, Cerambycidae). The collections of a little-known species of Phryneta, P. bicoloripennis, described by Stephan von Breuning in 1965 based on two specimens collected in 1908 in the region of Bamenda, indicate that this species...
Malaria transmission from humans to mosquitoes was assessed in two neighbouring villages in a rural area near Yaoundé, Cameroon during high and low transmission seasons during 1998-2000, using several indices previously evaluated in different areas endemic for malaria but never directly compared. These indices were estimated from human parasitologi...
The size of tsetse flies is often associated with population dynamics and vectorial capacity parameters. Adult fly size is generally estimated from measurements of wing segments. To take measure of the wing, a semi-automatic software was developed by CIRAD-EMVT and IRD. It was used in wild populations of Glossina tachinoides Westwood and G. palpali...
Dans les études de dynamique de population des glossines, vecteurs des trypanosomoses en Afrique, la taille de l'insecte peut être mise en relation avec leur longévité et leur capacité vectorielle. La taille des individus est généralement appréciée par la mesure de nervures remarquables de l'aile. Un logiciel semi-automatique a été développé par le...
A 2-yr longitudinal malaria study was undertaken in a suburb of Yaounde, the capital city of Cameroon, in the village of Simbock, approximately 2 km from the city limits. This study allowed assessment of malaria transmission intensity and dynamics in this region before implementation of pyrethroid impregnated bed nets through the national vector co...
We conducted parasitological and entomological malaria surveys among the population of Mengang district in southern Cameroon to analyse the relationship between malaria transmission intensity and malaria morbidity. We investigated two adjacent areas which differ 10-fold in transmission intensity [annual entomological inoculation rate (EIR) 17 vs. 1...
A survey in Cameroon compared the usefulness of the circumsporozoite protein enzyme-linked immunosorbent assay (CSP ELISA) to dissection and microscopic examination of anopheline salivary glands for measuring infectivity rates in anopheline mosquitoes. The salivary glands of 375 females, belonging to four species were examined for sporozoites. Afte...
Human infectiousness to mosquitoes can be estimated by 2 tests: direct feeding on the skin and membrane feeding on venous
blood. To validate the membrane feeding assay, the infectiousness of Plasmodium falciparum gametocyte carriers to Anopheles gambiae was estimated by these 2 methods in the same individuals in a rural area of Cameroon. Results fr...
In order to describe malaria transmission in a future antigamete vaccine trial area, a longitudinal entomological study was conducted, together with parasitological and immunological surveys, from June 1997 to May 1998 in two nearby villages in a tropical rain forest area 100 km east of Yaoundé. Koundou is located along the main road in an open and...

Koundou est situé au bord de l'axe...
Studies on the susceptibility of Anopheles gambiae to insecticides were carried out in rice field areas of Côte-d'Ivoire.

Adult populations from the surroundings of Bouake were resistant to DDT and permethrin. Resistance to pro...
Malaria is a major cause of morbidity and mortality in Ivory Coast. This fact justifies further epidemiological investigations to define regional features and allow implementation of the most suitable control measures. To this end, a study focusing on transmission of malaria was conducted between January and May 1993 concurrently with malarial para...
