The ribosomal protein S27a (RPS27a) is cleaved from the fusion protein ubiquitin–RPS27a
(Ub–RPS27a). Generally, Ub and RPS27a are coexpressed as a fusion protein but function …

A brief account of the history of insect morphology is given. Different techniques and
analytical methods used in current projects on insect morphology and phylogeny and their …

Food quality is a critical environmental condition that impacts an animal's growth and
development. Many insects facing this challenge have evolved a phenotypically plastic …

Environmental conditions can alter the form, function, and behavior of organisms over short
and long timescales, and even over generations. Aphid females respond to specific …

Crowding and changes in food availability are two critical environmental conditions that
impact an animal's trajectory toward either migration or reproduction. Many insects facing …

Individual dispersal decisions may be affected by the internal state of the individual and the
external information of its current environment. Here we estimated the influence of dispersal …

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 …

Most aphids exhibit wing polyphenism, in which winged and wingless females are produced
depending on aphid densities. Although juvenile hormone (JH) has been implicated in the …

Aphids exhibit wing polyphenism. Winged and wingless aphid morphs are produced by
parthenogenesis depending on population density and host plant quality. Recent studies …

Background In many insect taxa, wing polymorphism is known to be a consequence of
tradeoffs between flight and other life-history traits. The pea aphid Acyrthosiphon pisum …
