Research ArticleOpen accessIn the abstractForensically Flies Detect the Nutritional Value of Corpses Through Neuro-Chemoreceptive Cells-(5th Cell)Hedayat Abdel Ghaffar, Tarek Tantawi, Ibrahim Gaboub et al.Animals have evolved several chemosensory systems for detecting potentially dangerous foods in the environment. Activation of specific sensory cells within these chemosensory systems usually elicits an aversive behavioral response, leading to avoidance of the noxious foods. Blowflies respond to sugars, salts and water through the activation of specific chemoreceptor neurons in the antennal, labellar and tarsal chemosensillae. These insects also … …Neuroscience International, Vol. 3, Issue 2 · 5 Sep 2012 · 7,243 accessesView PDF Cite

Andrew C. Beattie et al.Problem statement: Evidence of rejection or acceptance by phytophagous pests of citrus plants treated with mineral oils suggests that impacts of oils may be related to detection by olfactory and/or contact chemoreceptors of repellent oils or plant volatiles. Alternatively, the oils may mask or suppress attractant host plant volatiles. To date, no studies have reported that oils elicit an olfactory … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 30 Jan 2012 · 8,782 accessesView PDF Cite
