“…A biphasic calcium signal was observed in all recordings. As in previous studies using bath-applied Calcium Green(45), a high contrast measure for the intensity of the odor-induced response was obtained by averaging three consecutive frames at the end of the odor presentation (frames [19][20][21] and subtracting the average of 3 frames during the second, negative component of the signal (frames 49-51).…”

“…However, the development of neurogenetic tools during the 20 th century has provided unprecedented progress in our understanding of the neural basis of behavior in other model species. Among others, this approach allowed to decipher the brain circuits underlying aggressive behavior (20), courtship (21), or memory (22) in a limited set of model species, both vertebrates such as mouse or zebrafish and invertebrates. In insects, the fruit fly Drosophila melanogaster has been for many years the leading model for investigating the neural basis of behavior, from gene expression to neural circuits (23–25).…”

Sociality is classified as one of the major transitions in evolution, and the most advanced level of sociality is found in eusocial insects such as the honey bees. This sophisticated social behavior seems to be associated with higher cognitive abilities in these insects, however the study of their neural bases has been limited by the lack of tools that allow measuring neuronal activity simultaneously in different brain regions of the honey bee brain. Here, we developed the first pan-neuronal genetic driver in a Hymenopteran model organism, the honey bee, and expressed the calcium indicator GCaMP6f under the control of the honey bee synapsin promoter. We show that GCaMP6f is widely expressed in the honey bee brain, allowing to record neural activity from multiple brain regions simultaneously, including from poorly investigated brain regions such as the mushroom body calyces or the lateral horn. Our recordings show that while odorant quality (chemical structure) and quantity are faithfully encoded in the honeybee antennal lobe, odor coding in the lateral horn departs from this simple physico-chemical coding, in line with the role of this structure in coding the biological value of odorants. These brain recordings represent the first use of a neurogenetic tool for recording neural activity in a eusocial insect.

Understanding of the neural bases for complex behaviors in Hymenoptera insect species has been limited by a lack of tools that allow measuring neuronal activity simultaneously in different brain regions. Here, we developed the first pan-neuronal genetic driver in a Hymenopteran model organism, the honey bee, and expressed the calcium indicator GCaMP6f under the control of the honey bee synapsin promoter. We show that GCaMP6f is widely expressed in the honey bee brain, allowing to record neural activity from multiple brain regions. To assess the power of this tool, we focused on the olfactory system, recording simultaneous responses from the antennal lobe, and from the more poorly investigated lateral horn (LH) and mushroom body (MB) calyces. Neural responses to 16 distinct odorants demonstrate that odorant quality (chemical structure) and quantity are faithfully encoded in the honey bee antennal lobe. In contrast, odor coding in the LH departs from this simple physico-chemical coding, supporting the role of this structure in coding the biological value of odorants. We further demonstrate robust neural responses to several bee pheromone odorants, key drivers of social behavior, in the LH. Combined, these brain recordings represent the first use of a neurogenetic tool for recording large-scale neural activity in a eusocial insect and will be of utility in assessing the neural underpinnings of olfactory and other sensory modalities and of social behaviors and cognitive abilities.

“…For insects, reproductive success is determined by a combination of factors, such as courtship, mating, and oviposition. Generally, male insects must perform courtship rituals by releasing sex pheromones, singing, and dancing to please the females 8–10 . To ensure offspring survival and health, mated females search for the best place to lay their eggs 11 .…”

Many species of the Tephritidae family are invasive and cause huge damage to agriculture and horticulture, owing to their reproductive characteristics. In this review, we have summarized the existing studies on the reproductive behavior of Tephritidae, particularly those regarding the genes and external factors that are associated with courtship, mating, and oviposition. Furthermore, we outline the issues that still need to be addressed in fruit fly reproduction research. The review highlights the implications for understanding the reproductive behavior of fruit flies and discusses methods for their integrated management and biological control.This article is protected by copyright.
