Innate responses are often sexually dimorphic. Studies of female specific behaviors have remained niche, but the focus is changing as illustrated by recent progress in understanding courtship and egg-laying decisions. In this review, we will cover our current knowledge about these two contexts. Recent studies elucidate on how females process song. They also show that decisions extremely complex, requiring assessment food, microbial, predator social cues. Study improve a nervous system processes different challenges.

Genetic approaches in the fruit fly, Drosophila melanogaster, have led to a major triumph field of sensory biology-the discovery multiple large families receptors and channels. Some these families, such as transient receptor potential channels, are conserved from animals ranging worms humans, while others, "gustatory receptors," "olfactory "ionotropic restricted invertebrates. Prior identification flies, it was widely assumed that proteins function just one modality vision, smell, taste, hearing, somatosensation, which includes thermosensation, light, noxious mechanical touch. By employing vast combination genetic, behavioral, electrophysiological, other concept emerge is many multitaskers. The earliest example this idea individual channels senses. It now clear multitasking exhibited by including gustatory receptors, ionotropic epithelial Na+ (also referred Pickpockets), even opsins, were formerly thought exclusively light sensors. characterizations neurons express them also reveal mechanisms through flies can accurately differentiate between different stimuli when they activate same receptor, well adaptation, amplification, integration. insights gleaned studies been highly influential directing investigations animal models.

It has been shown that gut microbes are very important for the behavior and development of Drosophila, as beneficial involved in identification suitable feeding egg-laying locations. However, what way these associated influence fitness-related behaviors Drosophila melanogaster remains unclear. Here, we show D. exhibits different behavioral preferences towards microbes. Both adults larvae were attracted by volatile compounds Saccharomyces cerevisiae Lactobacillus plantarum, but repelled Acetobacter malorum assays, indicating an olfactory mechanism is preference behaviors. While attraction to yeast was governed sensory neurons expressing odorant co-receptor Orco, observed other retained flies lacking this co-receptor. By experimentally manipulating microbiota flies, found did not strive a diverse microbiome increasing their they had experienced previously. Instead, some cases, even increased on which reared. Furthermore, exposing all three promoted development, while exposure only S. A. resulted larger ovaries egg numbers oviposition assay. Thus, our study provides better understanding how affect insect offers ecological rationale natural environment.

The decision to consume or reject a food based on the degree of acidity is critical for animal survival. However, gustatory receptors that detect sour compounds and influence feeding behavior have been elusive. Here, using fly, Drosophila melanogaster, we reveal member ionotropic receptor family, IR7a, essential rejecting foods laced with high levels acetic acid. IR7a dispensable repulsion other acidic compounds, indicating sensation acids occurs through repertoire rather than single receptor. fly’s main taste organ, labellum, decorated bristles house dendrites neurons (GRNs). expressed in subset bitter GRNs dedicated taste. Our findings indicate flies receptors, enabling them discriminate basis acid composition just pH.

Finding a suitable oviposition site is challenging task for gravid female moth. At the same time, it of paramount importance considering limited capability most caterpillars to relocate alternative host plants. The hawkmoth, Manduca sexta (Sphingidae), oviposits on solanaceous Larvae hatching plant that already attacked by conspecific can face food competition, as well an increased exposure predators and induced defenses. Here, we show feces from are sufficient deter M. ovipositing this deterrence based feces-emitted carboxylic acids 3-methylpentanoic acid hexanoic acid. Using combination genome editing (CRISPR-Cas9), electrophysiological recordings, calcium imaging, behavioral analyses, demonstrate ionotropic receptor 8a (IR8a) essential acid-mediated avoidance in hawkmoths.

Egg-laying behavior is one of the most important aspects female behavior, and has a profound impact on fitness species. As such, it controlled by several layers regulation. Here, we review recent advances in our understanding insect neural circuits that control when, where how to lay an egg. We also outline outstanding open questions about egg-laying decisions, speculate possible underpinnings can drive diversification oviposition behaviors through evolution.

Ionotropic receptors (IRs) are a highly divergent subfamily of ionotropic glutamate (iGluR) and conserved across Protostomia, major branch the animal kingdom that encompasses both Ecdysozoa Lophothrochozoa. They broadly expressed in peripheral sensory systems, concentrated dendrites, function chemosensation, thermosensation, hygrosensation. As iGluRs, four IR subunits form functional ion channel to detect environmental stimuli. Most comprise individual stimulus-specific tuning one or two coreceptors. This review summarizes discoveries structure complexes expression each IR, as well discusses future direction for studies.
