“…Mean percentages (±SE) on the right report flies that did not choose either the control or the strain. Asterisks indicate significant differences between the number of flies that chose the control and the strain according to the Friedman-ANOVA and Wilcoxon signed-rank tests with a Bonferroni correction (P \ 0.05) factor after 48 h. The role of 2-propanone is quite controversial: although this compound is reported to be a repellant for vinegar flies (Elamrani et al 2001), Riveron et al (2009) showed that 2-propanone can be repellent or attractive to D. melanogaster according to its concentration. Moreover, Newby and Etges (1998) reported that 2-propanone is a general attractant to D. mojavensis and can engender increased adult longevity.…”

Olfactory attraction of Drosophila suzukii by symbiotic acetic acid bacteria

Some species of acetic acid bacteria (AAB) play relevant roles in the metabolism and physiology of Drosophila spp. and in some cases convey benefits to their hosts. The pest Drosophila suzukii harbors a set of AAB similar to those of other Drosophila species. Here, we investigate the potential to exploit the ability of AAB to produce volatile substances that attract female D. suzukii. Using a two-way olfactometer bioassay, we investigate the preference of D. suzukii for strains of AAB, and using solid-phase microextraction gas chromatography-mass spectrometry we specifically characterize their volatile profiles to identify attractive and non-attractive components produced by strains from the genera Acetobacter, Gluconobacter, and Komagataeibacter. Flies had a preference for one strain of Komagataeibacter and two strains of Gluconobacter. Analyses of the volatile profiles from the preferred Gluconobacter isolates found that acetic acid is distinctively emitted even after 2 days of bacterial growth, confirming the relevance of this volatile in the profile of this isolate for attracting flies. Analyses of the volatile profile from the preferred Komagataeibacter isolate showed that a different volatile in its profile could be responsible for attracting D. suzukii. Moreover, variation in the concentration of butyric acid derivatives found in some strains may influence the preference of D. suzukii. Our results indicate that Gluconobacter and Komagataeibacter strains isolated from D. suzukii have the potential to provide substances that could be exploited to develop sustainable mass-trapping-based control approaches

“…However, at the single neuronal level, temperature can modulate the chemosensitivity of GG neurons; a mechanism that could be implicated in the fine adjustments necessary to modulate the sensitivity of the neurons exposed to the outside environment. Interestingly, this thermo-tuning of olfactory sensing is present throughout the animal kingdom such as in nematodes (Adachi et al, 2008) or in insects (Zeiner and Tichy, 2000; Riveron et al, 2009), indicating an inherited and conserved adaptation to the environmental pressure.…”

The mouse Grueneberg ganglion (GG) is an olfactory subsystem located at the tip of the nose close to the entry of the naris. It comprises neurons that are both sensitive to cold temperature and play an important role in the detection of alarm pheromones (APs). This chemical modality may be essential for species survival. Interestingly, GG neurons display an atypical mammalian olfactory morphology with neurons bearing deeply invaginated cilia mostly covered by ensheathing glial cells. We had previously noticed their morphological resemblance with the chemosensory amphid neurons found in the anterior region of the head of Caenorhabditis elegans (C. elegans). We demonstrate here further molecular and functional similarities. Thus, we found an orthologous expression of molecular signaling elements that was furthermore restricted to similar specific subcellular localizations. Calcium imaging also revealed a ligand selectivity for the methylated thiazole odorants that amphid neurons are known to detect. Cellular responses from GG neurons evoked by chemical or temperature stimuli were also partially cGMP-dependent. In addition, we found that, although behaviors depending on temperature sensing in the mouse, such as huddling and thermotaxis did not implicate the GG, the thermosensitivity modulated the chemosensitivity at the level of single GG neurons. Thus, the striking similarities with the chemosensory amphid neurons of C. elegans conferred to the mouse GG neurons unique multimodal sensory properties.

“…The number of odor molecules of a compound in the gas phase will be reduced when temperatures decrease (see example in [33]). Simply put, there will be less for a mosquito to smell when it is cooler outside.…”
