WebOct 26, 2024 · Gustatory systems in phytophagous insects are used to perceive feeding stimulants and deterrents, and are involved in insect decisions to feed on particular plants. During the process, gustatory receptors (Grs) can recognize diverse phytochemicals and provide a molecular basis for taste perception. WebDec 11, 2024 · Plant-eating insects use their sense of taste to decide where to feed and where to lay their eggs. They do this using taste sensors called gustatory receptors which reside in the antennae and legs of adults, and in the mouthparts of larvae. Some of these sensors detect sugars which signal to the insect that the plant is a nutritious source of food.
