How Do Flies Taste Spicy Food?

Scientists are still not sure exactly how flies taste spicy food, but they do know that they have five different types of gustatory response neurons (GRNs). The A, B, C, and D GRNs respond to different levels of salt and spicyness. The OtopLA receptor is expressed in each one, and it is thought to play a crucial role in flies’ aversion to strongly acidic foods.

Flies have taste receptors on their lower legs and feet, and they have taste buds just like humans do. As a result, they can share the flavor of spicy food. They also defecate on anything they find tasty, and they don’t care where they defecate. Infested flies defecate everywhere they land.

Tree shrews, meanwhile, have taste receptors located all over their bodies. Their wing tips, legs, and food-sucking proboscis also contain taste receptors. Although the taste organs of mice and flies are similar, tree shrews do not seem to have the same sensory organs as humans. As a result, they don’t seem to be sensitive to the spicy smell of peppers.

Researchers have studied the origins of spices. Chilis are a rich source of capsaicin, a chemical that causes the sensation of burning in our mouths. This chemical stimulates our TRPV1 receptors, which in turn detect spiciness and transmit pain signals.
