The question asks which pheromone is most likely involved when a queen walks on combs and leaves residues detectable by workers. 
Option 1: tarsal pheromone. While insects can use tarsal secretions for detection or contact cues, in honey bees the classic signaling pheromones associated with the queen are not described as primarily tarsal in origin. This makes this option less likely to be the primary queen-produced cue.
Option 2: ethyl oleate. In honey bee biology, ethyl oleate is a chemical associated with worker regulation and brood/foraging contexts rather than being the queen’s primary signal. It is more often discussed as a worker-derived olfactory cue rather than the queen’s message, so it does not fit as the most likely queen-related pheromone.
Option 3: queen mandibular pheromone. This is the well-established queen pheromone produced by the queen’s mandibular glands. It is a key chemical cue that workers detect on the comb when the queen moves around, helping to maintain colony organization, suppress worker ovary development, and modulate worker behavior. Because the queen literally leaves residues that workers detect and respond to, this option matches the known mechanism most directly.
Option 4: alarm pheromone. The alarm pheromone in bees is typically isopentyl acetate released from sting glands to alert and mobilize the colony to threats. This is a defensive signal, not the queen’s normal residue cue used to regulate worker activities on the comb, so it is unlikely to be the correct answer here.
Taking all choices into account, the queen mandibular pheromone best fits the description of a queen-produced residue that workers detect on the comb to coordinate colony behavior. The other options describe signals either from other sources (workers) or signals serving different functions (alarm), which do not align with the scenario described.
