Molecular bases of insect odorant receptor function: specificity and evolution

open access: yesBiological Reviews, Volume 101, Issue 2, Page 1036-1049, April 2026.
ABSTRACT Insect odorant receptors (ORs) are a class of chemoreceptors that insects use to detect volatile cues in their environment. In recent years, major advances in the field of structural biology have made it possible to obtain the first structures of insect ORs.

Flight attraction of Spodoptera littoralis (Lepidoptera, Noctuidae) to cotton headspace and synthetic volatile blends [PDF]

open access: yes, 2015
The insect olfactory system discriminates odor signals of different biological relevance, which drive innate behavior. Identification of stimuli that trigger upwind flight attraction toward host plants is a current challenge, and is essential in ...

Maintenance of Gut Microbial Balance via the Kynurenine Pathway Improves Larval Performance and Resistance to Bacillus thuringiensis in Spodoptera exigua

open access: yesMicrobiologyOpen, Volume 15, Issue 2, April 2026.
CRISPR/Cas9‐mediated deletion of kmo in Spodoptera exigua abolished 8‐HQA production, disrupted gut microbial homeostasis, and promoted Enterococcus dominance in gut and oral secretion. Mutants exhibited impaired growth, delayed development, and increased susceptibility to Bacillus thuringiensis, highlighting a conserved role of the kynurenine pathway ...

Enhancing toxicity of pyrethroids by oxidase and esterase inhibitors in Spodoptera littoralis (Boisd.) larvae [PDF]

open access: yesJournal of Plant Protection Research
Although pyrethroids are increasingly being used to control a number of agricultural insect pests, especially the cotton leafworm, Spodoptera littoralis (Boisd.), pyrethroid resistance is a major obstacle limiting effective control.
