Hormonal Control of the Phase Polyphenism of the Desert Locust: A Review of Current Understanding
An overview of the progress made to date in elucidating the hormonal control of the desert locust phase polyphenism is given and some questions that still need to be addressed are presented.
Polyphenism in Insects
Density-Dependent Phase Polyphenism in Nonmodel Locusts: A Minireview
It is found that locust phase polyphenism is expressed in many different ways in different locust species and a pattern is identified that locUST species often belong to large taxonomic groups which contain mostly nonswarming grasshopper species.
Locust research in the age of model organisms Introduction to the Special issue in honor of M . P . Pener ’ s 80 th birthday
The goal of collecting these works was to provide a venue through which a panorama of cutting-edge locust research could emerge, demonstrating that even nowadays, when research tends to focus increasingly on a few selected so-called model organisms, the locust has not lost its appeal as an outstanding preparation for physiological studies in various fields.

Locust Bacterial Symbionts: An Update
The current state of knowledge of the locust–bacteria interactions is described, as well as highlighting some newly-gained understanding; and some new perspectives for future research are offered.


Advances, controversies and consensus in locust phase polyphenism research
The present paper concerns the desert locust, Schistocerca gregaria, which has been the subject of most of the recent research, and is structured according to the major issues considered.
Molecular markers of phase transition in locusts
Decades of research revealed that phase transition implies changes in morphometry, the color of the cuticle, behavior and several aspects of physiology, and the answer to the most intriguing question, whether or not there is a primordial molecular inducer of phase transition, is probably not within reach in the very near future.
The endocrine control of phase transition: some new aspects
It is remarkable that the prothoracic glands persist longer in isolated‐reared adults, which implies that these glands continue to play a role, although they no longer release important amounts of ecdysteroids.
Phylogenetic perspectives on the evolution of locust phase polyphenism
It is demonstrated that locusts and closely related nonlocusts, express similar phenotypic plasticity due to phylogenetic conservatism, and it is argued that it is crucial to study the evolution of locust phase polyphenism from both adaptive and phylogenetic perspectives.
Corazonin and locust phase polyphenism
Transplantation of the brain and corpora cardiaca from various donors to albino locusts indicates the presence of corazonin or Corazonin-like substances in all 18 insect orders so far screened except for the Coleoptera.
Chemical ecology of locusts and related acridids.
The roles of chemotactile and olfactory cues together with tactile and visual stimuli in key locust processes, comprising gregarization, social cohesion, synchronous maturation, mating, oviposition, and maternal transfer of gregarious character are better understood.
There is evidence that phase gregaria locusts are more adult and less vegetative than solitaria, not only behaviourally and morphologically but also in their lesser fecundity and longevity.
