The attraction effect verification of sex pheromone trap for the Matsucoccus thunbergianae male
Matsucoccus thunbergianae is the main forest insect pest of the Japanese Black Pine (Pinus thunbergii) in the west, south and east coast of South Korea. The main damage pattern appears to be the cumulative damage over many years by the second instar fixed under the pine bark. The adult male has a pair of wings and is attracted sex pheromone emanating from the adult female so that during the mating period (Generally, middle period of March) adult male is attracted to the adult female which has no wing. Using this mating behavior from the adult male, we developed sex pheromone trap to reduce mating success rate by reducing the density of the adult male in the field. In this study, In the indoor induction experiments and the field experiments, sex pheromone trap showed high induction effect on the adult male. Thus, we expect to reduce the damage to the Japanese Black Pine by Matsucoccus thunbergianae.
