Environmental Stress Drives Plasticity in Sexual Bimaturism in the Black Soldier Fly (Hermetia illucens Linnaeus, 1758)

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 736-749, July 2026.
We measured the plasticity in sexual bimaturism (SBM; differences between sexes in the timing of sexual maturity) in the black soldier fly (BSF) by exposing larvae to nutrient availability and humidity stress. Our results show that SBM can range between protandry and protogyny depending on the environmental quality. Additionally, we found the degree of

Reconstruction 3D d'un insecte piégé dans l'ambre

open access: yes, 2020
National audienceIn this article, we focus on the 3D-reconstruction of an opaque object immersed in a refractive medium. More precisely , the case we are interested in is that of an insect trapped in amber.

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

open access: yesFunctional Ecology, Volume 40, Issue 6, Page 1906-1920, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Sugar provisioning increases parasitoid numbers in agroecosystems but may not reduce pest densities: A meta‐analysis

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings demonstrate that providing sugar sources reliably supports parasitoid populations and parasitism rate but does not systematically translate into improved pest suppression or yield gains. These results suggest that, for economic and practical reasons, sugar inputs at the edge of cultivated fields should be favoured.

Elimination des glossines et trypanosomoses animale : Résultats de quelques sondages dans la région du lac Tchad

open access: yesRevue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1978
Les enquêtes par sondages effectuées dans la vallée du Bas-Chari au Tchad pour juger de l'incidence de la disparition des glossines et des traitements trypanocides de masse sur l'épidémiologie des trypanosomoses locales (T. vivax et T. evansi) ont montré

Local canopy cover, shade tree identity and landscape tree cover shape leaf‐cutter ant nest density and herbivory in cacao agroforestry systems

open access: yesJournal of Applied Ecology, Volume 63, Issue 4, April 2026.
Our findings provide practical guidance for agroforestry management by demonstrating that intercropping with selected species can mitigate damage from leaf‐cutter ants in cacao agroforests. At the landscape scale, high tree cover was associated with low herbivory rates, emphasising the need to maintain or restore forested habitats.

Efficacité comparée de différents pièges pour la capture de Glossina tachinoides (Diptera : Glossinidae) au Burkina Faso

open access: yesRevue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1994
Cinq types de pièges sans produit olfactif sont comparés en saison sèche fraîche puis chaude le long de la rivière Comoé au Burkina Faso, pour leur efficacité vis-à-vis de Glossina tachinoides. Le piège biconique Challier-Laveissière donne les meilleurs

The ecology of attraction: Fruit traits and frugivore diversity in neotropical Piper

open access: yesFunctional Ecology, Volume 40, Issue 3, Page 611-623, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruit traits can benefit plant reproduction by enhancing seed dispersal by mutualistic frugivores (e.g. seed dispersal syndromes), but identifying the role of specific fruit traits in mediating frugivory is challenging because these traits can serve multiple functions ...
