Evolution of Oviposition Techniques in Stick and Leaf Insects (Phasmatodea)

open access: yesFrontiers in Ecology and Evolution, 2018
Stick and leaf insects (Phasmatodea) are large, tropical, predominantly nocturnal herbivores, which exhibit extreme masquerade crypsis, whereby they morphologically and behaviorally resemble twigs, bark, lichen, moss, and leaves.

Parental species and hybrid descendants of Bacillus (Insecta Phasmatodea) show different patterns of highly amplified, colocalized ribosomal and telomeric sequences

open access: yesThe European Zoological Journal, 2020
We investigated by dual-color fluorescence in situ hybridization (FISH) with 28S ribosomal and (TTAGG)n telomeric probes all species of the circum-Mediterranean genus Bacillus encompassing bisexual and parthenogenetic taxa, namely the three parental ...

Structure-Activity Studies on the Hypertrehalosemic Hormone II of the Stick Insect Carausius morosus (Phasmatodea): Carbohydrate-Mobilization and Cardio-Stimulatory Activities

open access: yesFrontiers in Physiology, 2020
The corpora cardiaca of the Indian stick insect, Carausius morosus, synthesize two decapeptide neuropeptides of the adipokinetic hormone (AKH) family, both of which can increase the trehalose levels in the hemolymph when the stick insect is ligated ...

Voltage‐gated proton channels in polyneopteran insects

open access: yesFEBS Open Bio, 2022
Voltage‐gated proton channels (HV1) are expressed in eukaryotes, including basal hexapods and polyneopteran insects. However, currently, there is little known about HV1 channels in insects.

Asexuality: The Insects that Stick With It [PDF]

open access: yesCurrent Biology, 2011
One hope of trying to understand why sex is so powerful and prevalent a mode of reproduction relies on the rare examples of animals that persist long-term without having sex. Now, several species of stick insects join that illustrious circle.

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

open access: yesAdvanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Multimodal Structural Color Graphics Based on Colloidal Photonic Microdome Arrays

open access: yesAdvanced Functional Materials, EarlyView.
A hybrid photonic system combining colloidal crystals and microscale domes is designed to achieve four switchable optical states via the interplay of Bragg reflection and TIR interference. The graphics composed of the photonic microdome arrays provide tunable, angle‐sensitive structural coloration and concealed‐to‐revealed transitions, offering a ...

Feeding Habits of Stick Insects [PDF]

open access: yesNature, 1936
THE observations1 from the Notre Dame Training College, Glasgow, on the eating of dead cellulose by Carausius, are very interesting in view of our experience at Strand School, where we have kept stick insects for upwards of twenty-five years, incidentally, without having detected a male.

A New Chinese Mesozoic Stick Insect [PDF]

open access: yesActa Palaeontologica Polonica, 2011
Renphasma sinica gen. et sp. nov. is described from the Early Cretaceous Yixian Formation in Liaoning. It has the general habitus of the Mesozoic “stick-insects”, with a short thorax, and broad and long tegmina, as long as the hindwings. Its pattern of tegmina venation is typical of the Mesozoic Phasmatodea, also present in the Eocene stick insect ...
