Abstract:

The research for chemical communication mechanism in Cerambycidae involved in identification of semiochemicals and application of them in the integrated pest management (IPM)，reproductive behaviour characters relative to semiochemicals．The elytra，thorax and cuticle are main position released pheromone．The carbon chain of short-range pheromones is generally more than 20 carbons and about 10 carbons or less than it in the long-range pheromones．These rules may provide information for the identification of pheromones later．Plant volatiles are applied to control beetles in the chemical communication by characteristics of function as attractant，repellent，antifeedant and ovipositional deterrent to regulate insect behavior．Short range pheromones or contact pheromones are more used to motivate mating behavior which showed physiological rhythm and phenomenon of mate protection，vision，colour，shape and size of body and cuticular chemicals are effect factors in the mating behavior．The clear understand of characteristics of semiochemicals and reproductive biology will benefit their effective application in IPM．

Key words: Cerambycidae, sex pheromone, plant volatiles, reproductive biology, integrated pest management, repellent
