assessed.•No clear causal relationship was found between both evolutionary …

Transcriptomic studies lend insights into the role of transcriptional plasticity in adaptation
and specialization. Recently, there has been growing interest in understanding the …

The planthoppers are piercing-sucking pests that continuously inject saliva into host plants
using specialized stylets. However, knowledge on the constituent and function of …

Cactophilic species of the Drosophila buzzatii cluster (repleta group) comprise an excellent
model group to investigate genomic changes underlying adaptation to extreme climate …

BACKGROUND The fall armyworm, Spodoptera frugiperda is one of the most destructive
agricultural pests, which can complete their entire life cycle on various plants. At present …

Host shift is ecologically advantageous and a crucial driver for herbivore insect speciation.
Insects on the non-native host obtain enemy-free space and confront reduced competition …

Interactions between plants and herbivorous insects have been models for theories of
specialization and co‐evolution for over a century. Phytochemicals govern many aspects of …

A detailed knowledge of gene function in the monarch butterfly is still lacking. Here we
generate a genome assembly from a Mexican nonmigratory population and used RNA-seq …

Background In many insect species, the larvae/nymphs are unable to disperse far from the
oviposition site selected by adults. The Sakhalin pine sawyer Monochamus saltuarius …

Background The chance to compare patterns of differential gene expression in related
ecologically distinct species can be particularly fruitful to investigate the genetics of …
