Journal ArticleDOI

Two genomes of highly polyphagous lepidopteran pests (Spodoptera frugiperda, Noctuidae) with different host-plant ranges

TL;DR: Signs of positive selection in genes involved in chemoreception, detoxification and digestion, and copy number variation in the two latter gene families are found, suggesting an adaptive role for structural variation.
Journal ArticleDOI

Degradation of pheromone and plant volatile components by a same odorant-degrading enzyme in the cotton leafworm, Spodoptera littoralis.

TL;DR: SlCXE7 expression was concomitant during development with male responsiveness to odorants and during adult scotophase with the period of male most active sexual behaviour, suggesting that a same ODE could have a dual function depending of it sensillar localisation.
Journal ArticleDOI

Characterization of an Antennal Carboxylesterase from the Pest Moth Spodoptera littoralis Degrading a Host Plant Odorant

TL;DR: It is suggested that a CCE-based intracellular metabolism of odorants could occur in insect antennae, in addition to the extracellular metabolism occurring within the sensillar lumen, the first functional characterization of an Odorant-Degrading Enzyme active towards a host plant volatile.
Journal ArticleDOI

A diversity of putative carboxylesterases are expressed in the antennae of the noctuid moth Spodoptera littoralis.

TL;DR: Bioinformatic analyses of a male antennal expressed sequence tag library allowed the identification of 19 putative esterase genes expressed in the antennae of the moth Spodoptera littoralis, suggesting a specific role in olfactory processing.
Journal ArticleDOI

A carboxylesterase, Esterase-6, modulates sensory physiological and behavioral response dynamics to pheromone in Drosophila.

TL;DR: Evidence is presented that Est-6 plays a role in the physiological and behavioral dynamics of sex pheromone response in Drosophila males and supports a role of Est- 6 as an odorant-degrading enzyme (ODE) in male antennae.
