12) Imаgine yоu аre аn insect physiоlоgist (I know, yuck!) working on pheromone detection and signal transduction in an economically important beetle that is used for the biological control of an invasive weed. In this species females use pheromone cues to find males at mating aggregations (i.e., male leks) and host odors to find host plants to feed on themselves and to lay their eggs. In your breeding colony in the laboratory, you discover a mutant line that responds to male pheromones, but not to host-plant odors. This makes them particularly difficult to rear so you are concerned. What could be disrupting the host-plant response but not the pheromone response? You find that by transplanting an antennal disc from a non-mutant into the mutant line rescues the ability to smell host plants, so the problem is likely in the antenna. What mechanisms of olfaction in the antenna may have been affected in this mutant beetle line? Provide three detailed hypotheses focused on the cellular/physiological mechanisms of olfaction in the antenna for how detection of host-plant odors could be disturbed in your lab colony of this species.
