Sometimes biosynthesis of the pheromone occurs only when biochemical precursors in the form of certain alkaloids have been ingested from food plants. In this case, the sex pheromone simultaneously signals the presence of food sources. [47] The uptake of pheromone precursors from plants is also known for certain species of orchid bees and ...

Trail pheromones are semiochemicals secreted from the body of an individual to affect the behavior of another individual receiving it. Trail pheromones often serve as a multi purpose chemical secretion that leads members of its own species towards a food source, while representing a territorial mark in the form of an allomone to organisms outside of their species.

Females release their pheromones at a specific time of day called the "calling time". For C. promethea this time is late afternoon and into the early evening. [9] When males sense the pheromones of a female they travel up the gradient of the pheromones and towards the female. Males are able locate females from miles away.
Pheromones can also be used to bait plants that are staples for M. histrionica and trap the insects. M. histrionica are major pests of plants in the family Brassicaceae . [ 10 ] In a study conducted by Ludwig and Kok (2001), researchers tested broccoli, mustard and rape plants for attractiveness to the harlequin bug and found that these plants ...
When a beekeeper lifts out frames from a hive they disturb the balance of smells within the hive. It can take up to 48 hours for the colony to re-establish its scent equilibrium. A synthetically produced Nasonov pheromone can be used to attract a honey bee swarm to an unoccupied hive or a swarm-catching box.
