Trapping of Monochamus alternatus by Different Ratio of Aggregation Pheromone and Plant Volatile Attractant

Experiments were conducted on trapping of Monochamus alternatus by alone or combination of aggregation pheromone and plant volatile attractant, and different dosages of aggregation pheromone (0.02, 0.05, 0.10, 0.50, 1.0, 2.0 mL) during June 15th 2018 and July 27th, June 15th 2018 and July 30th, June 24th 2018 and July 22th in 15-25- year mixed forest of Pinus massoniana and P. taeda in Lin’an, Zhejiang province. The results showed that plant volatile attractant and aggregation pheromone could significantly increase trapped M. alternatus, which was 1.5 and 13.7 time of plant volatile attractant and aggregation pheromone alone. Aggregation pheromone with 0.02-1.0 mL could increase the amount of trapped M. alternatus.
