Insulin receptors and wing dimorphism in rice planthoppers [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2017 Wing polymorphism contributes significantly to the success of a wide variety of insects. However, its underlying molecular mechanism is less well understood. The migratory planthopper (BPH), Nilaparvata lugens , is one of the most extensively studied insects for wing polymorphism, due to its ...

A large genomic insertion containing a duplicated follistatin gene is linked to the pea aphid male wing dimorphism [PDF]
eLife, 2020 Wing dimorphisms have long served as models for examining the ecological and evolutionary tradeoffs associated with alternative phenotypes. Here, we investigated the genetic cause of the pea aphid (Acyrthosiphon pisum) male wing dimorphism, wherein males

Transcriptome profiling of maternal stress‐induced wing dimorphism in pea aphids [PDF]
Ecology and Evolution, 2019 AbstractWing dimorphism, that is, wingless and winged forms, can be induced by maternal stress signals and is an adaptive response of aphids to environmental changes. Here, we investigated the ecological and molecular effects of three kinds of stress, namely crowding, predation, and aphid alarm pheromone, on wing dimorphism.

Sexual size dimorphism and morphological sex determination in the Yellow-browed Bunting (Emberiza chrysophrys) [PDF]
BMC ZoologyBackground Sex-differential migration patterns may coevolve with sexual size dimorphism, and reliable field sexing is necessary to understand this relationship.

Scaling Relationships and Sexual Size Dimorphism Among the Body Parts of Holotrichia oblita (Coleoptera: Scarabaeidae) [PDF]
Ecology and EvolutionSexual dimorphism is common among insects. However, whether dimorphism influences the wing loading (i.e., body mass per unit wing area) and scaling relationships among body parts in beetles has seldom been explored.

Comprehensive full-Length transcriptomic resource for wing dimorphism in English green aphid, Sitobion avenae [PDF]
Scientific DataThe English green aphid, Sitobion avenae, a major pest of wheat, exhibits classical wing dimorphism. To support research and data sharing on the molecular basis of this trait, we generated full-length transcriptomes from three different developmental ...

Pharmacological Effects of NADPH Oxidase Inhibitors on Butterfly Wing Morphogenesis and Color Pattern Formation in Junonia orithya [PDF]
InsectsDuring the early pupal stage in butterflies, the peripheral portion of wing tissue undergoes apoptosis to finalize adult wing morphology, and wing color patterns are determined coordinately.

Sexual dimorphism in Sturnira lilium (Chiroptera, Phyllostomidae): can pregnancy and pup carrying be responsible for differences in wing shape? [PDF]
PLoS ONE, 2012 Competition is one of the most cited mechanisms to explain secondary sexual dimorphism in animals. Nonetheless, it has been proposed that sexual dimorphism in bat wings is also a result of adaptive pressures to compensate additional weight caused by ...

Variation of sexual dimorphism of the wing shape in the family Dolichopodidae (Diptera) [PDF]
Samara Journal of Science, 2022 Although sexual dimorphism manifestations are widespread in the family Dolichopodidae, a detailed characterization of their phylogenetic significance is lacking. In order to study the distribution patterns of wing sexual dimorphism, we have analyzed 57 species from 17 genera of 9 subfamilies.

European Journal of Entomology, 2022 Intraspecific variation and sexual dimorphism in wing shape and size is common in winged insects. The exact patterns, however, differ among taxa and are related to the selection pressure acting on specific traits.
