Polyphenism, in which multiple discrete phenotypes develop from a single genotype, is
considered to have contributed to the evolutionary success of aphids. Of the various …

Abstract Background The Hemiptera (aphids, cicadas, and true bugs) are a key insect order,
with high diversity for feeding ecology and excellent experimental tractability for molecular …

Reproduction is a fundamental feature of life, it is the way life persists across the ages. This
book offers new, wider vistas on this fundamental biological phenomenon, exploring how it …

Nuclear receptors are a family of transcription factors that are often responsive to small
ligands, allowing for efficient gene expression-level responses to a stimulus. The average …

In insect embryos, anteroposterior patterning is coordinated by the sequential expression of
the 'timer'genes caudal, Dichaete, and odd-paired, whose expression dynamics correlate …

Aphids are soft-bodied plant sap-sucking insects from family Aphididae (Order Hemiptera,
Suborder Sternorrhyncha, Infraorder Aphidomorpha, Superfamily Aphidoidea). They are …

The structure of the reproductive system of the sexual generation—males and oviparous
females—of the pea aphid Acyrthosiphon pisum (Harris)(Hemiptera, Aphididae), a serious …

Embryonic terminal patterning and moulting are critical developmental processes in insects.
In Drosophila and Tribolium both of these processes are regulated by the Torso‐activation …

Phenotypic plasticity is an adaptive response to environmental cues (DeWitt and Scheiner
2004, Ghalambor et al. 2007, Simpson et al. 2011). An extreme example is phenotypic …

Background Germline specification in some animals is driven by the maternally inherited
germ plasm during early embryogenesis (inheritance mode), whereas in others it is induced …
