Interaction of semiochemicals with model lipid membranes: A biophysical approach
(Elsevier Science, 2018-01)
Unravelling the chemical language of insects has been the subject of intense research in the field of chemical ecology for the past five decades. Insect communication is mainly based on chemosensation due to the small body ...
Testing detection and discrimination of vegetation chemical cues in the subterranean rodent Ctenomys talarum
(Universita Degli Studi Di Firenze, 2010-07)
Previous studies on the subterranean rodent Ctenomys talarum (tuco-tuco) have shown that this species has the ability to use olfaction to orient their digging while foraging. As a continuation of these works, we assess ...
Plasticity in insect olfaction: to smell or not to smell?
(Annual Reviews, 2016-03)
In insects, olfaction plays a crucial role in many behavioral contexts, such as locating food, sexual partners, and oviposition sites. To successfully perform such behaviors, insects must respond to chemical stimuli at the ...
Antennal sensilla of cleptoparasitic and non-parasitic bees in two subfamilies of Apidae
(EDP Sciences, 2017-01)
In bees, most of the comparative studies linking the sensory system and behavior were performed in social species. Here, we describe the morphology of antennal sensilla in solitary and cleptoparasitic bees of Apinae and ...
Post-mating sexual abstinence in a male moth
(Landes Bioscience, 2014-10)
In most animals, male copulation is dependent on the detection and processing of female-produced sex pheromones. In males, a refractory postejaculatory interval (PEI) follows copulation, allowing them to avoid direct ...
Morphology and physiology of the olfactory system of blood-feeding insects
(Elsevier, 2014-04)
Several blood-feeding (hematophagous) insects are vectors of a number of diseases including dengue, Chagas disease and leishmaniasis which persistently affect public health throughout Latin America. The vectors of those ...
Spatial Repellency Caused by Volatile Pyrethroids is Olfactory-Mediated in the German Cockroach Blattella germanica (Dictyoptera: Blattellidae)
(Sociedade Entomológica do Brasil, 2019-10)
Pyrethroids are synthetic insecticides that have a repellent action. This effect has been associated with an increase in the locomotor activity, which causes the avoidance of the insecticide-treated area (excito-repellency). ...
Diagnostic Value of Combined Acute Levodopa Challenge and Olfactory Testing to Predict Parkinson's Disease
(Wiley, 2017-11)
Background: The diagnosis of Parkinson's disease (PD) can be challenging early in the diseasecourse, when motor features are subtle. The objective of this study was to explore the diagnostic value ofcombining acute levodopa ...
The Antennal Sensilla of Oxelytrum erythrurum (Blanchard) and Oxelytrum apicale (Brullé) (Coleoptera: Silphidae)
(Sociedade Entomológica do Brasil, 2012-10)
The typology and placement of antennal sensilla of the carrion beetles Oxelytrum erythrurum (Blanchard) and Oxelytrum apicalis (Brullé) (Coleoptera: Silphidae) were studied using scanning electron microscopy. Two types of ...
Plant odour stimuli reshape pheromonal representation in neurons of the antennal lobe macroglomerular complex of a male moth
(Company of Biologists, 2012-05)
Male moths are confronted with complex odour mixtures in a natural environment when flying towards a female-emitted sex pheromone source. Whereas synergistic effects of sex pheromones and plant odours have been observed ...
