Differences in wings may be sufficient to separate the sexes and two species of Gynaikothrips Zimmermann (Thysanoptera: Phlaeothripidae)?

open access: yesEntomoBrasilis, 2022
In this study, we use geometric morphometry to discriminate thrips of the species Gynaikothrips uzeli (Zimmerman) and Gynaikothrips ficorum (Marchal) and also to detect sexual dimorphism in these species. Two hundred individuals, one hundred females and

Sexual size and shape dimorphism, and allometric scaling in the pupal and adult traits of Eristalis tenax

open access: yesEcology and Evolution, 2023
The patterns and amount of variation in size, shape, and/or life history traits between females and males are fundamentally important to gain the comprehensive understanding of the evolution of phenotypic diversity.

Relationship between flight muscle dimorphism and wing morphometry in Triatoma infestans (Klug, 1834) (Hemiptera, Reduviidae, Triatominae)

open access: yesFrontiers in Ecology and Evolution, 2023
Triatoma infestans, the primary vector of Chagas disease in southern South America, is reported as a dimorphic species for flight muscle development and presents a marked phenotypic plasticity in traits related to flight.

Species morphospace boundary revisited through wing phenotypic variations of Antodynerus species (Hymenoptera: Vespidae: Eumeninae) from the Indian subcontinent

open access: yesFrontiers in Ecology and Evolution, 2023
The main objective of this study was to investigate the taxonomic significance of wing phenotypic variations (size and shape) for classifying potter wasps.

The miR-9b microRNA mediates dimorphism and development of wing in aphids [PDF]

open access: yesProceedings of the National Academy of Sciences, 2020
Wing dimorphism is a phenomenon of phenotypic plasticity in aphid dispersal. However, the signal transduction for perceiving environmental cues (e.g., crowding) and the regulation mechanism remain elusive. Here, we found that aci-miR-9b was the only down-regulated microRNA (miRNA) in both crowding-induced wing dimorphism and during

Identification of genes underlying phenotypic plasticity of wing size via insulin signaling pathway by network-based analysis in Sogatella furcifera

open access: yesBMC Genomics, 2019
Background Phenotypic plasticity is a common and highly adaptive phenomenon where the same genotype produces different phenotypes in response to environmental cues. Sogatella furcifera, a migratory pest of rice exhibits wing dimorphism, is a model insect

THE EVOLUTION OF WING DIMORPHISM IN INSECTS [PDF]

open access: yesEvolution, 1986
Wing-dimorphic insects are excellent subjects for a study of the evolution of dispersal since the nondispersing brachypterous morph is easily recognized. The purpose of this paper is to develop a framework within which the evolution of wing dimorphism can be understood.

Evolution of sexual size dimorphism in the wing musculature of Drosophila

open access: yesPeerJ, 2020
Male courtship songs in Drosophila are exceedingly diverse across species. While much of this variation is understood to have evolved from changes in the central nervous system, evolutionary transitions in the wing muscles that control the song may have also contributed to song diversity ...

When size and shape matter: morphometric characterization of two sympatric dragonflies of the genus Perithemis (Odonata: Libellulidae)

open access: yesAnais da Academia Brasileira de Ciências, 2023
Perithemis mooma, Kirby, 1889 and Perithemis icteroptera (Selys in Sagra, 1857) live in sympatry from southern Brazil to central Argentina. The taxonomy of the genus Perithemis Hagen, 1861 has been hampered by the use of characters that are highly ...

Wing Dimorphism in Weevils [PDF]

open access: yesNature, 1928
IN a reference which appeared in NATURE of July 28, p. 144, to my paper on the inheritance of long and short wings in the weevil, Sitona hispidula (Trans. Boy. Soc. Edin., vol. 55, part 3, No. 27), a statement occurs which it is desirable to correct. It is stated in the note that evidence from breeding indicates that the abnormal condition of the wing ...
