Insect parapheromone are trace amounts of volatile chemical substances that are released from the body of insects to the outside of the body, which can cause behaviors or physiological reactions of other individuals of the same or different species. Insect pheromone plays an important role in biological communities, and mastering the code of insect pheromone can create conditions for humans to effectively use insects. After long-term research, the chemical structure of a large number of insect parapheromone has been known, and humans can already obtain insect parapheromone through artificial synthesis or extraction technology, which creates favorable conditions for the application of insect parapheromone to prevent pests. And insect pheromone has the advantages of high activity, strong specificity, gradual use, no pollution to the environment, no harm to natural enemies, etc. Its use can effectively slow down the pollution of pesticides to the environment. There are many kinds of insect parapheromone, and they are divided into alcohols, carboxylic acids, esters, aldehydes, olefins, etc. according to their chemical structure. Few reports of insect parapheromone containing carboxyl functional groups have been reported. So far, only the bee trail parapheromone has been found to contain carboxyl functional groups. In the honeybee, its role is to determine the direction of the honeybee in the external environment.
