4. Vibrational
5. Chemical

Question 2

What are semiochemicals?

Answer 2

Many insect rely on smell for communication. They are chemical scents that are important for both interspecific and intraspecific communication

Question 3

4 Types of Semiochemicals

Answer 3

1. Pheromone (Exchange between individuals of the same species)
2. Allomone (Interspecific that benefit the emitter and not receiver)
3. Kairomone (interspecific that benefit the receiver and not emitter)
4. Synomone (interspecific and benefit both parties)

Question 4

What are the two types of pheromone components?

Answer 4

1. Monocomponent (one chemical)
2. Multicomponent (more than one chemical)

Question 5

5 Types of pheromones
