A central challenge in evolutionary biology is to identify genes underlying ecologically
important traits and describe the fitness consequences of naturally occurring variation at …

Chemosensory speciation is characterized by the evolution of barriers to genetic exchange
that involve chemosensory systems and chemical signals. Here, we review some …

Insects comprise the largest species composition in the entire animal kingdom and possess
a vast undiscovered genetic diversity and gene pool that can be better explored using …

Sex pheromone communication, acting as a prezygotic barrier to mating, is believed to have
contributed to the speciation of moths and butterflies in the order Lepidoptera. Five decades …

Pheromone-based behaviours are crucial in animals from insects to mammals,, and
reproductive isolation is often based on pheromone differences,,,. However, the genetic …

Much of what we know about speciation comes from detailed studies of well‐known model
systems. Although there have been several important syntheses on speciation, few (if any) …

The speciose insect order Lepidoptera (moths and butterflies) and their closest relatives,
Trichoptera (caddis flies), share a female-heterogametic sex chromosome system. Originally …

1. The moth Spodoptera frugiperda presents an interesting opportunity to study the evolution
of reproductive isolation, because it consists of two host races that may be in the process of …

Background The European corn borer (ECB), Ostrinia nubilalis (Hubner), exists as two
separate sex pheromone races. ECB (Z) females produce a 97∶ 3 blend of Z11-and E11 …

Of 12 potential reproductive isolating barriers between closely related Z-and E-pheromone
strains of the European corn borer moth (Ostrinia nubilalis), seven significantly reduced …
