Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

A new genus and species of pemphredonine wasp in Late Cretaceous Vendean amber (Hymenoptera: Crabronidae) [PDF]

open access: yes, 2014
International audienceA new genus and species of pemphredonine wasp is described and figured in Late Cretaceous (Cenomanian to Santonian) amber from Vendée, in northwestern France. Menopsila dupeae n. gen. and sp., is based on a partial male preserved in

The European honey buzzard (Pernis apivorus) as an ally for the control of the invasive yellow‐legged hornet (Vespa velutina nigrithorax)

open access: yesPest Management Science, Volume 81, Issue 4, Page 2237-2247, April 2025.
The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.

The predatory behavior of ants: an impressive panoply of morphological adaptations

open access: yesInsect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Studies on pollinator fauna and their relative abundance of sunflower (Helianthus annuus L.) at Pantnagar, Uttarakhand, India [PDF]

open access: yes, 2013
Pollinators provide key services to both natural and agricultural ecosystems. Agricultural productivity depends, in part on pollinator populations from adjacent semi natural habitats.The diversity and abundance of different insect visitors on sunflower ...

Behavioral, Ecological, and Morphological Data Suggest a Close Relationship Between the Ant Colobopsis truncata and the Gall Wasp Aphelonyx cerricola

open access: yesIntegrative Zoology, EarlyView.
Aphelonyx cerricola and the different stages that make this gall colonizable by ants. ABSTRACT Wasps of the family Cynipidae are known to induce galls of a species‐specific morphology, which during senescence provide a refuge for secondary insect fauna, especially ants.

New Results From the Pre‐Pottery Neolithic Site of Al Uyaynah, Tabuk, in Northwestern Saudi Arabia

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Al Uyaynah is a low sandstone mound on an alluvial plain, long known for its extensive surface remains of stone‐built circular and rectangular structures. Following test excavations in 2012, more detailed excavation was undertaken in 2016 within one of the largest rectangular stone structures.

Rainfall shapes the physiological condition, but not the body size, of an introduced dung beetle in Brazilian pastures

open access: yesEcological Entomology, Volume 51, Issue 2, Page 346-355, April 2026.
Understanding rainfall‐driven physiological shifts in dung beetles is crucial to predict how climate change may affect the fitness and persistence of key insect species in tropical pastures. We compared body size, dry, lipid and muscle masses of Digitonthophagus gazella collected during dry and rainy seasons in Brazilian pastures to assess the effects ...

A Female‐Locust‐Inspired Hybrid Soft‐Stiff Robotic Digger: Mimetics and Implications for Digging Efficiency

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 3, March 2026.
Female desert locusts dig underground to lay their eggs. They displace soil, rather than removing it, to create a tunnel. We analyze burrowing dynamics and 3D kinematics and design a locust‐inspired hybrid soft–stiff robot that reproduces this mechanism. The results show the natural strategy minimizes energy, whereas alternative patterns raise costs up
