“…Enigmatically, 1-octen-3-ol remains the most common chemostimulus eliciting varied behaviors in almost every hematophagous arthropod studied so far, ranging from ticks, triatomines, mosquitoes, midges, stable flies and sand flies. The GC-EAD method has since been used to isolate and identify important chemostimuli for mosquitoes, triatomines, and tsetse flies with the resulting chemostimuli proving to be behaviorally active [22].…”

“…For insects, the precise discrimination and interpretation of what is an essentially unlimited spectrum of chemical information impacts numerous behavioral decisions that directly contribute to their success and in many cases, survival. To interpret these signals insects utilize a range of molecular components that center around several large families of chemosensory receptors which are housed in a diverse array of hair-like structures called sensilla that are non-randomly distributed across peripheral appendages such as the antennae, maxillary palps, or labials (reviewed in [1]). The number and type of sensilla present on chemosensory appendages vary according to species as well as their developmental stage (e.g., larvae vs. adults), and gender.…”

Olfactory signaling is a crucial component in the life history of insects. The development of precise and parallel mechanisms to analyze the tremendous amount of chemical information from the environment and other sources has been essential to their evolutionary success. Considerable progress has been made in the study of insect olfaction fueled by bioinformatics- based utilization of genomics along with rapid advances in functional analyses. Here we review recent progress in our rapidly emerging understanding of insect peripheral sensory reception and signal transduction. These studies reveal that the nearly unlimited chemical space insects encounter is covered by distinct chemosensory receptor repertoires that are generally derived by species-specific, rapid gene gain and loss, reflecting the evolutionary consequences of adaptation to meet their specific biological needs. While diverse molecular mechanisms have been put forth, often in the context of controversial models, the characterization of the ubiquitous, highly conserved and insect-specific Orco odorant receptor co-receptor has opened the door to the design and development of novel insect control methods to target agricultural pests, disease vectors and even nuisance insects.

“…These examples demonstrate that essential knowledge on the evolution of the insect olfactory system can be obtained from its comparative analysis in well‐chosen taxa. Thus, comparing the organization of the AL and its specific adaptations in terms of glomerular number, size, and input–output connectivity may allow one to understand adaptations linked to changes in diet, host preference, or social life style in Hymenoptera (Rospars, ; Zube and Rössler, ; Kelber et al, ; Dacks et al, ; Ibba et al, ; Das and Fadamiro, ; Guidobaldi et al, ).…”

In the course of evolution, eusociality has appeared several times independently in Hymenoptera, within different families such as Apidae (bees), Formicidae (ants), and Vespidae (wasps and hornets), among others. The complex social organization of eusocial Hymenoptera relies on sophisticated olfactory communication systems. Whereas the olfactory systems of several bee and ant species have been well characterized, very little information is as yet available in Vespidae, although this family represents a highly successful insect group, displaying a wide range of life styles from solitary to eusocial. Using fluorescent labeling, confocal microscopy, and 3D reconstructions, we investigated the organization of the olfactory pathway in queens, workers, and males of the eusocial hornet Vespa velutina. First, we found that caste and sex dimorphism is weakly pronounced in hornets, with regard to both whole-brain morphology and antennal lobe organization, although several male-specific macroglomeruli are present. The V. velutina antennal lobe contains approximately 265 glomeruli (in females), grouped in nine conspicuous clusters formed by afferent tract subdivisions. As in bees and ants, hornets display a dual olfactory pathway, with two major efferent tracts, the medial and the lateral antennal lobe tracts (m- and l-ALT), separately arborizing two antennal lobe hemilobes and projecting to partially different regions of higher order olfactory centers. Finally, we found remarkable anatomical similarities in the glomerular cluster organizations among hornets, ants, and bees, suggesting the possible existence of homologies in the olfactory pathways of these eusocial Hymenoptera. We propose a common framework for describing AL compartmentalization across Hymenoptera and discuss possible evolutionary scenarios. J. Comp.
