Problems solved by technology

[0003] The characteristics of the spruce beetle under the bark of the host tree have brought great difficulties to the control work
The use of traditional chemical control methods such as chemical fumigation and tree trunk spraying has achieved certain effects, but the side effects of high control costs, poor effect, killing natural enemies and polluting the environment have also emerged.

example 1

[0038] Example 1. Selection of lures: Canada company( http: / / www.pherotech.com / ) has been commercialized to produce cis-3-hexenyl-1-ol, cis-verbenaenol and 2-methyl-3-buten-2-ol three kinds of lures containing slow-release carrier pheromone, field test results It proves that using the lures sold by the company according to the above combination method can achieve the required trapping effect, therefore, the above combination can be purchased directly. The weight of the three kinds of pheromone lures is 1 gram, and the release rate is 25-30 mg / d. Each trap can trap 64 spruce octopus beetles within a radius of 300 meters per day on average at the peak of flying.

example 2

[0039] Example 2, three kinds of pheromone lures of cis-3-hexenyl-1-alcohol, cis-verbenol and 2-methyl-3-buten-2-alcohol described in the selection example 1, wherein cis- 3.2 grams of 3-hexenyl-1-ol, 0.8 grams of cis-verbena-enol and 2-methyl-3-buten-2-ol, the release rate is 10 mg / d, and each trap is flying On average, the peak can lure 39 spruce bark beetles within a radius of 300 meters per day.

example 3

[0040] Example 3, three kinds of pheromone lures of cis-3-hexenyl-1-alcohol, cis-verbenol and 2-methyl-3-buten-2-alcohol described in the selection example 1, wherein cis- 0.8 grams of 3-hexenyl-1-ol, 2.5 grams of cis-verbenaenol, 3.2 grams of 2-methyl-3-buten-2-ol, the release rate is 45 mg / d, and each trap is On average, Feifeng can trap 46 octopus beetles within a radius of 300 meters per day.

Abstract

The invention discloses a method for attracting Ips typographus by utilizing pheromones, which relates to the technical field of forest pest control. Cis-3-Hexen-1-ol, cis-verbenol and 2-methyl-3-Buten-2-ol are adopted as the pheromones for attraction, wherein the three pheromones are placed into an air-permeable slow release carrier respectively, and the release speed rates are all controlled within the range of between 10 and 50mg / d. An Ips typographus attractant has broad application prospect, is particularly suitable to be popularized and applied to peasants due to the low cost of a formula, achieves the aims of species group monitoring and control, can minimize the loss of the damage of the Ips typographus in our country, and has economic, social and ecological benefits.

Description

Technical field: [0001] The invention relates to the technical field of forest pest control, in particular the invention relates to a method for attracting forest borers. Background technique: [0002] The spruce beetle Ips typographus Linnaeus belongs to the order Coleoptera, the family Scolytidae, and the genus Ips. It is widely distributed in the entire Palaearctic region and is one of the most harmful bark beetles in Europe. [1] . The spruce bark beetle is a secondary pest that harms natural spruce forests (generally mature and over-mature forests). It can directly harm healthy standing trees under suitable conditions or occurs rampantly, and together with other bark beetles can cause forest damage. Large areas die, causing huge losses to forestry production and ecological environment construction, and seriously threatening the growth and function of water conservation forests. There are about 18 species of host trees known worldwide, among which Picea koraiensis and P...
