Post‐eclosion temperature effects on insect cuticular hydrocarbon profiles

Ecology and Evolution, 2021
The insect cuticle is the interface between internal homeostasis and the often harsh external environment. Cuticular hydrocarbons (CHCs) are key constituents of this hard cuticle and are associated with a variety of functions including stress response ...

Preimaginal development of Aedes aegypti L. (Diptera: Culicidae) in brackish water gives rise to adult mosquitoes with thicker cuticles and greater insecticide resistance

Medical and Veterinary Entomology, Volume 40, Issue 4, Page 759-773, December 2026.
The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...

Insights into pupal development of Bactrocera dorsalis: factors influencing eclosion

Scientific Reports
In the life cycle of the oriental fruit fly where larvae reside within fruits and adults exhibit high activity, the pupal stage occurs in the soil, closely tied to agricultural soil management.

The influence of pupal colour on diapause and post‐diapause success in the swallowtail butterfly Papilio machaon

Physiological Entomology, Volume 51, Issue 4, Page 575-583, December 2026.
The swallowtail butterfly Papilio machaon has a brown‐ and green‐coloured morph, with the brown being more common in the diapausing generation. The darker colouration of brown pupae did not confer advantages for thermoregulation when developing, but they did have lower diapause metabolic rates.

Comparative Analysis of Diel and Circadian Eclosion Rhythms and Clock Gene Expression Between Sexes in the Migratory Moth Spodoptera frugiperda

Insects
The circadian clock orchestrates behavioral and molecular processes such as eclosion. Understanding eclosion timing may offer insights into circadian mechanisms underlying migratory timing.

RÉTENTION DES OVULES APRÈS OVULATION DANS LA CAVITÉ OVARIENNE DE LA CARPE HERBIVORE : COMPOSITION DES OVULES ET CAPACITÉ DE DÉVELOPPEMENT DES ŒUFS ET DES ALEVINS.

Knowledge and Management of Aquatic Ecosystems, 2002
Pour étudier l’effet de rétention prolongée des ovules dans la cavité ovarienne (in vivo) de la carpe herbivore, des extractions d’ovules de 15 femelles (3 à 5,6 kg) ont eu lieu à différents intervalles de temps après ovulation (0, 30, 60, 90 et 120 min).

Asymmetric Evolution of Antennal Cell Types Underlies a Derived Ammonia‐Sensing Logic for Ecological Adaptation in Bactrocera dorsalis

Advanced Science, Volume 13, Issue 62, 9 November 2026.
Comparative antennal single‐nucleus transcriptomics reveals cell‐type‐dependent transcriptomic divergence in Bactrocera dorsalis, with similar structural cells but divergent sensory neurons. This neuronal diversification is associated with a distinct ammonia‐sensing pathway, linking female attraction to bird‐dropping‐associated cues with nutritional ...

Herbivory‐Induced Stomatal Opening Triggers the Dispersal of an Invasive Insect Herbivore

Advanced Science, Volume 13, Issue 62, 9 November 2026.
The invasive leafminer Phthorimaea absoluta uniquely manipulates plant defenses by inducing stomatal opening in tomato. This response, mediated by the stomatal regulator IQM1, enhances the release of the repellent volatile benzaldehyde. This volatile triggers the dispersal of adult moths, facilitates colonization of new hosts, and leads to rapid ...

Experience Improves Spatial Foraging Performance in a Complex Environment in Heliconius Butterflies

Ecology and Evolution, Volume 16, Issue 11, November 2026.
We experimentally tested whether prior experience in a spatially complex environment influences foraging performance in the pollen‐feeding butterfly Heliconius erato. Butterflies reared in a structurally complex environment efficiently reached a feeder under both familiar and unfamiliar conditions, whereas those reared in a simple environment performed

Two Triflumuron Application Methods on Glossina palpalis gambiensis in the Laboratory: Impact on Female Fertility

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 2003
The objective of this study was to compare the efficacy of two triflumuron-application methods on male tsetse flies to achieve transfer of the product to the females during subsequent mating.
