Design of a Morphing Wingtip [PDF]

Journal 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...

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

Nature 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 ...

Transcriptome Analysis of the Regulatory Mechanism of FoxO on Wing Dimorphism in the Brown Planthopper, Nilaparvata lugens (Hemiptera: Delphacidae)

Insects, 2021
The brown planthopper (BPH), Nilaparvata lugens, can develop into either short-winged (SW) or long-winged (LW) adults according to environmental conditions, and has long served as a model organism for exploring the mechanisms of wing polyphenism in ...

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

PLoS 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.

Molecular and behavioral studies reveal differences in olfaction between winter and summer morphs of Drosophila suzukii [PDF]

PeerJ, 2022
Spotted-wing drosophila, Drosophila suzukii (Matsumura), is a major economic pest of several fruit crops in Europe, North and South America, and other parts of the world because it oviposits in ripening thin-skinned fruits.

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

PLoS 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.

Comparative transcriptional analysis provides insights of possible molecular mechanisms of wing polyphenism induced by postnatal crowding in Aphis gossypii

Journal of Cotton Research, 2019
Background Aphis gossypii is a worldwide sap-sucking pest with a variety of hosts and a vector of more than 50 plant viruses. The strategy of wing polyphenism, mostly resulting from population density increasing, contributes to the evolutionary success ...

Density‐dependent sex‐biased development of macroptery in a water strider

Ecology and Evolution, 2020
In wing‐polymorphic insects, wing morphs differ not only in dispersal capability but also in life history traits because of trade‐offs between flight capability and reproduction. When the fitness benefits and costs of producing wings differ between males

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

Frontiers 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 ...
