Embodiment Construction

[0013] Below in conjunction with embodiment the present invention is described in further detail as follows:

[0014] a. During the flying period of the Huashan pine beetle, through field investigations, the distribution area of ​​Huashan pine was divided into the damaged area, the uninjured area and the non-Huashan pine distribution area;

[0015] b. Combine the host volatiles (R)-(+)-α-pinene, (–)-β-pinene and (+)-3-carene with the aggregation pheromone frontalin, exo - brevicomin and myrtenal, formulated as attractants at a volume ratio of 20:20:20:1:1:1;

[0016] c. Put the prepared attractant into a 20mL slow-release bottle, and hang the funnel-shaped bark beetle trap with the slow-release bottle in the distribution area of ​​Wuhuashan pine;

[0017] d. Take the anti-aggregation pheromone verbenone of the Huashan pine beetle as the solute and the liquid paraffin that has no attracting and avoiding effects on the Huashan pine beetle as the solvent, and prepare the anti-a...

Abstract

The invention discloses a method for dendroctonus armandi disorientation control by pheromones. The method includes the steps: dividing an armandi distribution area into an affected area, an unaffected area and an armandi-free distribution area in an emergence period of dendroctonus armandi; preparing host plant volatiles and dendroctonus armandi aggregation pheromones into attractants; suspendinga slow-release bottle with the attractants in the armandi-free distribution area; preparing anti-aggregation substances by taking anti-aggregation pheromones and organic matter liquid without attracting and avoiding functions for the dendroctonus armandi as solvents. By combined use of the aggregation pheromones and the anti-aggregation pheromones, the efficiency of the dendroctonus armandi harming healthy armandi is effectively reduced, and the problem of difficulty in field control of the dendroctonus armandi in the emergence period is solved. By comprehensively using three identified aggregation pheromone substances of the dendroctonus armandi, the efficiency of trapping and attracting the dendroctonus armandi is improved, and the dendroctonus armandi is disorientated.

Description

technical field [0001] The invention relates to a control method for the Huashan pine beetle, in particular to a method for preventing and controlling the Huashan pine beetle by using the aggregation pheromone and the anti-aggregation pheromone of the Huashan pine beetle, and belongs to the field of plant protection. Background technique [0002] Huashan pine ( Pinus armandi ) is the dominant tree species in the Qinba forest region of my country, mostly located at an altitude of 1500-2200 meters, and the distribution of natural forests is mainly dot-shaped, which plays an important role in the stability of the ecological environment. However, since the 1970s, there have been more than 3×10 8 m 3 Huashan pine due to Huashan pine beetle ( Dendroctonus armandi ) to death. The Huashan pine beetle belongs to the Coleoptera (Coleoptera) Scolytidae (Scolytidae) genus ( Dendroctonus ), the Huashan pine beetle is a pioneer pest in the Bashan forest area of ​​the Qinling Mounta...
