The first myriapod genome sequence reveals conservative arthropod gene content and genome organisation in the centipede Strigamia maritima. [PDF]

open access: yes, 2014
Myriapods (e.g., centipedes and millipedes) display a simple homonomous body plan relative to other arthropods. All members of the class are terrestrial, but they attained terrestriality independently of insects. Myriapoda is the only arthropod class not

The South American fruit fly : an important pest insect with RNAi-sensitive larval stages [PDF]

open access: yes, 2019
RNA interference (RNAi) technology has been used in the development of approaches for pest control. The presence of some essential genes, the so-called "core genes," in the RNAi machinery is crucial for its efficiency and robust response in gene ...

Challenging Evolutionary Paradigms: Daphnia Populations Resurrected From Unpolluted Environments Show Enhanced Detoxification Ability to Aromatic Pollutants

open access: yesMolecular Ecology, Volume 35, Issue 4, February 2026.
ABSTRACT Understanding how organisms respond to chemical stress requires disentangling genetically encoded (constitutive) adaptations from environmentally induced (plastic) responses. This challenge is particularly acute for polycyclic aromatic hydrocarbons (PAHs), widespread aquatic pollutants with well‐documented toxicity, where mechanisms of ...

Annotation of novel neuropeptide precursors in the migratory locust based on transcript screening of a public EST database and mass spectrometry

open access: yesBMC Genomics, 2006
Background For holometabolous insects there has been an explosion of proteomic and peptidomic information thanks to large genome sequencing projects. Heterometabolous insects, although comprising many important species, have been far less studied.

Genetic analysis of Eclosion hormone action during Drosophila larval ecdysis [PDF]

open access: yes, 2015
Insect growth is punctuated by molts, during which the animal produces a new exoskeleton. The molt culminates with ecdysis, an ordered sequence of behaviors that causes the old cuticle to be shed. This sequence is activated by Ecdysis Triggering Hormone (

Effects of Dietary Calcium and Magnesium Levels on the Growth Performance, Tissue Mineral Deposition, Exoskeleton Development, and Molting Performance of Chinese Mitten Crab (Eriocheir sinensis)

open access: yesAquaculture Nutrition, Volume 2026, Issue 1, 2026.
Calcium and magnesium are essential mineral elements for animal growth and development, playing crucial roles in skeletal formation, particularly in the molting process of crustaceans. However, their interaction is still poorly elucidated. This study investigated the effects of dietary calcium and magnesium levels on the growth performance, tissue ...

The role of juvenile hormone and insulin/TOR signaling in the growth of Manduca sexta [PDF]

open access: yes, 2015
In many insect species, fitness trade-offs exist between maximizing body size and developmental speed. Understanding how various species evolve different life history strategies requires knowledge of the physiological mechanisms underlying the regulation

Dynamic eIF3‐S6 Phase Separation Switch Instructed by m6A Modification Drives the Molting of Locusts

open access: yesAdvanced Science, Volume 12, Issue 39, October 20, 2025.
This research reveals that reduced m6A modifications during insect molting trigger liquid–liquid phase separation (LLPS) of the m6A reader eIF3‐S6, which binds and stabilizes key molting mRNAs, including EcR and Cht10. Disrupting m6A or LLPS causes cuticle remodeling defects and molting failure, highlighting the synergistic control of gene expression ...

A crab is not a fish: unique aspects of the crustacean endocrine system and considerations for endocrine toxicology [PDF]

open access: yes, 2021
International audienceCrustaceans—and arthropods in general—exhibit many unique aspects to their physiology. These include the requirement to moult (ecdysis) in order to grow and reproduce, the ability to change color, and multiple strategies for sexual ...

Surface Topography and Ultrastructure of the Spectacular Cells in the Eyes of Land and Sea Snakes (Squamata, Reptilia): Functional Adaptations of Micro‐Ornamentation

open access: yesJournal of Morphology, Volume 286, Issue 9, September 2025.
ABSTRACT Although the surface micro‐ornamentation of the scales within the skin of snakes has been the subject of many previous studies, there has been little work done on the spectacle, a protective (keratinised) goggle separated from the underlying cornea by a sub‐spectacular space. The surface ultrastructure of the “Oberhäutchen” of the spectacle is
