Note – Gestion des Jussies dans le Marais Poitevin

Sciences, Eaux & Territoires, 2014
Le maillage hydraulique dense du réseau hydrographique et la quasi-absence de débit estival font du Marais Poitevin une zone particulièrement favorable aux développements de plantes aquatiques.

And then there was us Et puis nous sommes apparus

Journal of the Royal Anthropological Institute, EarlyView.
In 1987, the academic conference ‘Origins and Dispersals of Modern Humans: Behavioural and Biological Perspectives’ was held in Cambridge, UK. Subsequently referred to as the ‘Human Revolution’ conference, this meeting brought together the most prominent academics working in the field of human origins, including archaeologists and palaeoanthropologists,

From the predator to the prey: a case study of the vulnerability of Harmonia axyridis to aggressive competitors

Insect Science, EarlyView.
The level of aggressiveness of an individual is a factor that shapes intraguild predation (IGP) interactions. In Nabis americoferus, high aggressiveness leads to an increase in attack rate and IGP against Harmonia axyridis. Moreover, the absence of extraguild prey seems to exacerbate IGP. In docile N.

Biology, ecology and dynamics of Deborrea malgassa (Heylarts 1884) (Lepidoptera: Psychidae), the main threat to apple Malus domestica Borkh growing in Madagascar

Agricultural and Forest Entomology, EarlyView.
Bioecology parameters of the endemic Psychidae Deborrea malgassa, the main pest of apple trees in Madagascar. Spatiotemporal dynamics of Deborrea malgassa, with a peak infestation between May and August. Proposed targeted prophylaxis techniques associated with other agroecological principles will be key to reducing the vulnerability of apple orchards ...

Dispersion par les cours d'eau  des propagules végétatives et sexuées du complexe d'espèces Reynoutria [PDF]

Sciences, Eaux & Territoires, 2019
Chez les renouées asiatiques (complexe Reynoutria), l'eau des rivières est un des principaux vecteurs naturels de dispersion des propagules sexuées (akènes ailés) et végétatives (fragments de tiges et de rhizomes).

Rearing Istocheta aldrichi (Diptera: Tachinidae) From Field‐Collected Japanese Beetles (Popillia japonica): 1. Methods to Improve Insect Collection and Parasitoid Pupariation

Entomologia Experimentalis et Applicata, EarlyView.
We describe methods for collecting and rearing the tachinid parasitoid Istocheta aldrichi from parasitized Japanese beetle adults. Hosts can be collected by hand and reared in the laboratory, or by using modified trap containers with added plant material and substrate to provide suitable conditions for I.

Rearing Istocheta aldrichi (Diptera: Tachinidae) From Field‐Collected Japanese Beetles (Popillia japonica): 2. Methods to Improve Overwintering, Adult Emergence and Longevity

Entomologia Experimentalis et Applicata, EarlyView.
Successful rearing of Istocheta aldrichi, a tachinid parasitoid of invasive Japanese beetle, depended on conditions before, during, and after overwintering. Longer cold exposure increased adult emergence and accelerated post‐diapause development. Early transfer of puparia to cool conditions improved survival, while spring temperature manipulation ...
