Cucurbitacin B Activates Bitter-Sensing Gustatory Receptor Neurons via Gustatory Receptor 33a in Drosophila melanogaster. [PDF]
Mol Cells, 2020 The Gustatory system enables animals to detect toxic bitter chemicals, which is critical for insects to survive food induced toxicity. Cucurbitacin is widely present in plants such as cucumber and gourds that acts as an anti-herbivore chemical and an insecticide. Cucurbitacin has a harmful effect on insect larvae as well.

Bitter taste stimuli induce differential neural codes in mouse brain. [PDF]
, 2012 A growing literature suggests taste stimuli commonly classified as "bitter" induce heterogeneous neural and perceptual responses. Here, the central processing of bitter stimuli was studied in mice with genetically controlled bitter taste profiles.

Gustatory Receptors: Not Just for Good Taste [PDF]
Current Biology, 2013 A recent study has found that a Drosophila gustatory receptor is required for thermotaxis. With other fly gustatory receptors having been shown to act in the detection of CO2, nutrients in the brain, and light, the roles of the so-called 'gustatory receptors' clearly go way beyond peripheral detection of non-volatile chemicals.

Avoiding DEET through Insect Gustatory Receptors [PDF]
Neuron, 2010 DEET is the most widely used insect repellent worldwide. In Drosophila olfactory receptor neurons (ORNs), DEET is detected through a mechanism employing the olfactory receptor, OR83b. However, it is controversial as to whether ORNs respond directly to DEET or whether DEET blocks the response to attractive odors.

Chemosensory detection of aversive concentrations of ammonia and basic volatile amines in insects
iScience, 2023 Summary: Basic volatiles like ammonia are found in insect environments, and at high concentrations cause an atypical action potential burst, followed by inhibition in multiple classes of olfactory receptor neurons (ORNs) in Drosophila melanogaster ...

A Drosophila Gustatory Receptor Required for Strychnine Sensation. [PDF]
Chem Senses, 2015 Strychnine is a potent, naturally occurring neurotoxin that effectively protects plants from animal pests by deterring feeding behavior. In insects, such as the fruit fly, Drosophila melanogaster, bitter-tasting aversive compounds are detected primarily through a family of gustatory receptors (GRs), which are expressed in gustatory receptor neurons.

Plant insecticide L-canavanine repels Drosophila via the insect orphan GPCR DmX. [PDF]
PLoS Biology, 2009 For all animals, the taste sense is crucial to detect and avoid ingesting toxic molecules. Many toxins are synthesized by plants as a defense mechanism against insect predation.

Peripheral, central and behavioral responses to the cuticular pheromone bouquet in Drosophila melanogaster males. [PDF]
PLoS ONE, 2011 Pheromonal communication is crucial with regard to mate choice in many animals including insects. Drosophila melanogaster flies produce a pheromonal bouquet with many cuticular hydrocarbons some of which diverge between the sexes and differently affect ...

Gustatory receptors in Lepidoptera: chemosensation and beyond [PDF]
Insect Molecular Biology, 2016 Abstract Lepidoptera is one of the most widespread insect orders and includes several agriculturally important insect species. Ecological success of the lepidopteran insects partly depends on their adaptive chemoreception tactics, which play an important role in the selection of hosts, egg‐laying sites and mates ...
