A novel terpene synthase controls differences in anti-aphrodisiac pheromone production between closely related Heliconius butterflies.

open access: yesPLoS Biology, 2021
Plants and insects often use the same compounds for chemical communication, but not much is known about the genetics of convergent evolution of chemical signals.

Insects and Survival: A Review of Primary and Secondary Defense Strategies

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Disruptive sexual selection against hybrids contributes to speciation betweenHeliconius cydnoandHeliconius melpomene [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2001
Understanding the fate of hybrids in wild populations is fundamental to understanding speciation. Here we provide evidence for disruptive sexual selection against hybrids between Heliconius cydno and Heliconius melpomene. The two species are sympatric across most of Central and Andean South America, and coexist despite a low level of hybridization.

Evolutionary dynamics of genome size and content during the adaptive radiation of Heliconiini butterflies

open access: yesNature Communications, 2023
Heliconius butterflies, a speciose genus of Müllerian mimics, represent a classic example of an adaptive radiation that includes a range of derived dietary, life history, physiological and neural traits. However, key lineages within the genus, and across

Shifting Balancing Selection Underlies an Inversion Cline in Eurasian Blackcap

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
We investigated what factor contributes to a cline of a chromosomal inversion of the Eurasian blackcap, which differs from typical inversion clines maintained by divergent selection. Using a simulation‐based machine learning approach, we found that the inversion is under negative frequency‐dependent selection, and the optimal frequency is shifted ...

Summer Rainfall Drives Adaptation with Gene Flow in a Widespread Butterfly

open access: yesMolecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT Understanding how environmental variation interacts with gene flow to shape population genomic patterns is a central goal in evolutionary biology. We investigated how geographic and environmental differences impact genetic variation in the clouded sulfur butterfly (Colias philodice eriphyle) by conducting whole‐genome resequencing across ...

Female behaviour drives expression and evolution of gustatory receptors in butterflies.

open access: yesPLoS Genetics, 2013
Secondary plant compounds are strong deterrents of insect oviposition and feeding, but may also be attractants for specialist herbivores. These insect-plant interactions are mediated by insect gustatory receptors (Grs) and olfactory receptors (Ors).

Ancient and Recent Riverine Gene Flow Contributed to the Adaptive Radiation of Sailfin Silversides in Wallace's Dreampond

open access: yesMolecular Ecology, Volume 35, Issue 11, June 2026.
ABSTRACT While adaptive radiations significantly contribute to the world's biodiversity, much is unknown about the genetic and ecological factors underlying these rapid successions of speciation. It has been suggested that hybridisation can facilitate the speciation process by generating genetic diversity on which diversifying selection can act ...
