Morphometric criteria to differentiate Drosophila suzukii (Diptera: Drosophilidae) seasonal morphs. [PDF]

open access: yesPLoS ONE, 2020
Temperate insect species often enter diapause in preparation for overwintering. One such species is the invasive vinegar fly, Drosophila suzukii (Matsumura), which has seasonal polymorphisms, considered winter and summer morphs.

Insulin-related peptide 5 is involved in regulating embryo development and biochemical composition in pea aphid with wing polyphenism [PDF]

open access: yesFrontiers in Physiology, 2016
In aphids there is a fecundity-dispersal trade-off between wingless and winged morphs. Recent research on the molecular mechanism of wing morphs associated with dispersal reveals that insulin receptors in the insulin signaling (IS) pathway regulate ...

Vestigial mediates the effect of insulin signaling pathway on wing-morph switching in planthoppers. [PDF]

open access: yesPLoS Genetics, 2021
Wing polymorphism is an evolutionary feature found in a wide variety of insects, which offers a model system for studying the evolutionary significance of dispersal.

miR-34 modulates wing polyphenism in planthopper. [PDF]

open access: yesPLoS Genetics, 2019
Polyphenism is a successful strategy adopted by organisms to adapt to environmental changes. Brown planthoppers (BPH, Nilaparvata lugens) develop two wing phenotypes, including long-winged (LW) and short-winged (SW) morphs.

Two species? – Limits of the species concepts in the pygmy grasshoppers of the Tetrix bipunctata complex (Orthoptera, Tetrigidae) [PDF]

open access: yesZooKeys, 2021
Today, integrative taxonomy is often considered the gold standard when it comes to species recognition and delimitation. Using the Tetrix bipunctata complex, we here present a case where even integrative taxonomy may reach its limits.

Autonomous material composite morphing wing

open access: yesJournal of Composite Materials, 2023
Aeronautics research has continually sought to achieve the adaptability and morphing performance of avian wings, but in practice, wings of all scales continue to use the same hinged control-surface embodiment. Recent research into compliant and bio-inspired mechanisms for morphing wings and control surfaces has indicated promising results, though often

Design of a Morphing Wingtip [PDF]

open access: yesJournal of Aircraft, 2014
An initial design of a morphing wingtip for a regional jet aircraft is developed and evaluated. The adaptive wingtip concept is based upon a chiral-type internal structure, enabling controlled cant...

Insights into wing dimorphism in worldwide agricultural pest and host-alternating aphid Aphis gossypii

open access: yesJournal of Cotton Research, 2021
Background The worldwide pest Aphis gossypii has three-winged morphs in its life cycle, namely, winged parthenogenetic female (WPF), winged gynopara (GP), and winged male, which are all produced by a wingless parthenogenetic female (WLPF).

The transcription factor Zfh1 acts as a wing-morph switch in planthoppers

open access: yesNature Communications, 2022
The molecular mechanisms underlying wing polyphenism remain poorly understood. Here the authors use plant hoppers to show that the development of long and short wing morphs is balanced by the relative activities of the Zfh1-FoxO and insulin signaling ...
