Epigenetics and locust life phase transitions
- BiologyJournal of Experimental Biology
- 2015
Accumulating evidence points towards a role for epigenetic regulation in locust phase polyphenism, and this is corroborated in the economically important locust species Locusta migratoria and Schistocerca gregaria.

Epigenetic Molecular Mechanisms in Insects
- BiologyNeotropical Entomology
- 2020
This work discusses on how EMMs pervasive influences in Insecta require not only the control of gene expression but also the dynamic interplay of EMMs with further regulatory levels, including genetic, physiological, behavioral, and environmental among others, as was earlier proposed by the Probabilistic Epigenesis model and Developmental System Theory.
The genomewide transcriptional response underlying the pea aphid wing polyphenism
- BiologyMolecular ecology
- 2016
A genomewide study of the maternal transcriptome at two time points with and without a crowding stress is performed to discover the maternal molecular changes that lead to the development of winged vs. wingless offspring and posit a model for how maternal signals inform a developing embryo to be winged or wingless.
Life-History Evolution and the Polyphenic Regulation of Somatic Maintenance and Survival
- BiologyThe Quarterly Review of Biology
- 2013
It is suggested that dauer larval diapause and its associated adult phenotypes in the nematode, reproductive dormancy in the fruit fly and other insects, and the worker castes of the honey bee are examples of what may be viewed as the polyphenic regulation of somatic maintenance and survival.

Epigenetic mechanisms of insect polyphenisms

This thesis established the presence of allele-specific expression and methylation in B. terrestris and analysed whether genome-wide alternative splicing levels are an important component in ascertaining the varying levels of eusociality found in the Hymenoptera.
Induction of diapause and seasonal morphs in butterflies and other insects: knowns, unknowns and the challenge of integration
- BiologyPhysiological entomology
- 2013
There is still a limited understanding of how external cues and physiological pathways regulating various traits are interconnected via gene action to form a co‐adapted complete phenotype that is adaptive in the wild despite environmental fluctuation and change.
Mechanisms of phenotypic plasticity for wing morph differentiation in insects
- Biology
- 2015
The mechanisms of phenotypic plasticity for wing morph differentiation in insects are summarized and it is not yet clear how the evolutionary shifts of character variation is realized between environmental and genetic control.
Phenotypic plasticity in a generalist insect herbivore with the combined use of direct and indirect cues
- Environmental Science
- 2013
This work shows that the remarkable variability in the visual appearance of the larvae of the geometrid moth Ematurga atomaria, though genetically based in part, involves a substantial environmental component, and transformed the multidimensional variation in colour and pattern into two dimensions interpretable as patterning and darkness.

Gene expression and the evolution of insect polyphenisms †
- BiologyBioEssays : news and reviews in molecular, cellular and developmental biology

This work discusses polyphenisms and molecular genetic tools now available to unravel their developmental bases in insects and focuses on several recent studies that have tracked gene‐expression patterns during social insect caste determination.
Phenotypic plasticity and diversity in insects
- BiologyPhilosophical Transactions of the Royal Society B: Biological Sciences
- 2010
It is argued that phenotypic plasticity generates novel targets for evolutionary processes to act on, as well as brings about trade-offs during development and evolution, thereby diversifying evolutionary trajectories available to natural populations.
Developmental mechanisms of threshold evolution in a polyphenic beetle
- BiologyEvolution & development
- 2002
Larval larvae of populations that have evolved a larger threshold body size have to accumulate greater mass to become competent to express the horned morph, are less sensitive to the juvenile hormone (JH) analogue methoprene, and exhibit a delay in the sensitive period for meethoprene relative to other developmental events.
Evolution of a Polyphenism by Genetic Accommodation
- BiologyScience

It is shown that a mutation in the juvenile hormone-regulatory pathway in Manduca sexta enables heat stress to reveal a hidden reaction norm of larval coloration, facilitating the origin of novel adaptive phenotypes.
Rapid evolution of a polyphenic threshold
- BiologyEvolution & development

The results support the view that certain components of the developmental control mechanism that underlie polyphenic development can evolve rapidly in natural populations and may provide important avenues for phenotypic differentiation and diversification in nature.

The results suggest that differences in PKG enzyme activity are correlated to well-established phase-related behavioral differences, and lay the groundwork for functional studies of the locust for gene and its possible relations to locust phase polyphenism.

The life cycles of aphids are among the most remarkable of any animal group. They include parthenogenetic and sexual generations, elaborate polyphen isms, and obligate shifting between unrelated…
Aphid wing dimorphisms: linking environmental and genetic control of trait variation

Investigation into molecular mechanisms underlying phenotypic plasticity in the aphid wing dimorphism system is reviewed, offering the opportunity to compare and contrast the mechanistic basis of environmental and genetic control of similar dimorphisms.
Phylogenetic perspectives on the evolution of locust phase polyphenism
- Biology
- 2005
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.
