it is pheromone, Pheromones are chemical signal released into
environment by exocrine gland in insects, the pheromone
influence the behavior of individual belong to same species.
Why it is important --Insect can not think, therefore chemical
sense such as test and smell are important to them.
On the basis of type of activity they classified as follow:
1) sex attracting pheromone
2) aggregation pheromone
3) alarm pheromone
4) anti aggregation pheromone
5) trail making pheromone
