Defecation in preparation for ecdysis drives microplastic clearance in cricket nymphs

Physiological Entomology, EarlyView.
In preparation for ecdysis, cricket nymphs cease feeding and gradually clear their gut contents via frass production, which removes most ingested MPs from their digestive tract. Following exoskeletal moulting, the foregut lining, including any remaining MPs, is shed and excreted alongside frass approximately 6 h later.

Ovipositor morphology correlates with life history evolution in agaonid fig wasps

, 2018
International audienceThe high adaptive success of parasitic Hymenoptera might be related to the use of different oviposition sites, allowing niche partitioning among co-occurring species resulting in life history specialization and diversification.

Specialized ovipositor sensilla of Cretaceous wasps (Insecta: Hymenoptera) possibly reveal a unique way of host detection. [PDF]

Insects have evolved complex sensory systems that are important for feeding, defence and reproduction. Parasitoid wasps often spend much time and effort in searching for concealed hosts with the help of specialized sensilla.

Uncovering the Diversity of Mesostoinae (Hymenoptera: Braconidae): A Glimpse Into the Australian Fauna Through a Study of Kangaroo Island

Austral Entomology, Volume 65, Issue 4, November 2026.
ABSTRACT The Mesostoinae are a poorly understood braconid subfamily with unresolved morphological challenges and a complex taxonomic history. This study provides insight into the biodiversity of this subfamily on Kangaroo Island (KI), South Australia.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Drosophila species (Diptera: Drosophilidae) oviposition patterns on fungi: The effect of allospecifics, substrate toughness, ovipositor structure and degree of specialisation

European Journal of Entomology, 2003
To determine if small-scale resource partitioning aids coexistence in fungal breeding Diptera we investigated the avoidance of interspecific larval competition by micro-resource partitioning of the host substrate in several species of Drosophila ...

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

The Anatomical Record, Volume 309, Issue 9, Page 2298-2314, September 2026.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

Evolution of the α‐Glucosidase Gene Family in Apoidea

Ecology and Evolution, Volume 16, Issue 9, September 2026.
This study traces the origin of the α‐glucosidase gene family in bees back to approximately 140 million years ago, revealing that its evolutionary history closely aligns with the rise of angiosperms and coevolution. Furthermore, by identifying the core members Hbg1–3 and 28 key functional sites driven by positive selection, the study systematically ...

Pumping Venom: Valvilli Architecture in Diacamma (Hymenoptera: Formicidae) and Implications for Stinger Functionality

Journal of Morphology, Volume 287, Issue 9, September 2026.
The insect stinger is among the best‐known venom‐delivery structures, yet its valvilli—paired flaps within the valve chamber—remain poorly understood. Using micro‐CT, histology, serial block‐face SEM and CLSM in the ant Diacamma nr. indicum, we show that the valvilli are not uniformly flexible flaps but are materially differentiated structures with ...

Host‐associated chemical cues mediating host‐finding behaviour in the larval ectoparasitoid Cephalonomia tarsalis

Pest Management Science, Volume 82, Issue 9, Page 8459-8467, September 2026.
Host‐associated volatiles mediate host location in Cephalonomia tarsalis, with faecal odours from fourth‐instar larvae, particularly 1‐pentadecene, attracting females and supporting the biological control of stored‐product pest beetles. Abstract BACKGROUND Understanding how parasitoids locate their hosts is essential for improving the effectiveness of ...
