Problems solved by technology

Some scholars have also tried to use aggregation pheromone to lure the octodontid beetle. Since the morphological characteristics and phylogeny of this insect are similar to that of the spruce octopus (Cognato and Sun, 2007), they tried to use the spruce octopus Bark beetle pheromones are used to lure and monitor adult beetles, but because the two species are independent natural species, the effect of attracting insects is very unsatisfactory
In recent years, the forestry department of Qinghai Province has also tried to screen potential pheromone attractants in field experiments using known pheromone components and various combinations of the genus Dendrobium, but has not yet achieved any substantial breakthroughs

Embodiment 1

[0005] Embodiment 1: the gathering pheromone attractant that is used to lure the octodentate beetle, gets 970 milligrams of 2-methyl-3-buten-2-alcohol, 20 milligrams of (±)-bark beetle dienol, 10 mg of (S)-cis-verbenaenol, without adding trans-verbenaenol, mix the components evenly, and put them into a polyethylene plastic bag-type release carrier (lure) for use.

Embodiment 2

[0006] Embodiment 2: be used to lure the aggregation pheromone attractant of the octodentate beetle, get 650 mg of 2-methyl-3-buten-2-alcohol, 200 mg of (±)-beetle dienol, 100 mg of (S)-cis-verbenicenol and 50 mg of trans-verbenaenol, mix the components evenly, and put them into a bottle-type release carrier (lure) for use.

Embodiment 3

[0007] Embodiment 3: the gathering pheromone attractant that is used to lure the octodentate beetle, gets 2-methyl-3-butene-2-alcohol 900 milligrams, (±)-bark beetle dienol 50 milligrams, (S)-cis-verbenaenol 30 mg, trans-verbenaenol 20 mg, mix each component evenly, put it into a rubber plug-type release carrier (lure) for use.

Abstract

The invention discloses an aggregation pheromone attractant for attracting Ips nitdus Eggers to trap and kill Ips nitdus Egger, composed of following ingredients: 2-methyl-3-buten-2-ol of 65-90%, (+ / -)-ipsdienol of 2-20%, (S)-cis-verbenol of 1-10% and trans-verbenol of 0-5%. The ingredients of the attractant provided by the invention are mixed well, and loaded in delivery carriers (attracting cores) of PE plastic bag type, bottle type, rubber stopper type, etc. to use. The invention belonging to natural volatile organic substance has stable structure, and stable chemical property at normal temperature and pressure, compared with normal chemical control, has the characteristics of no toxicity, no pollution, high efficiency, safety to environment and natural enemies, and is suitable for the monitor of the emergence period, emergence zone, population dynamics of Ips nitdus Eggers and production control of large-area trapping and killing.

Description

Technical field: [0001] The invention belongs to pest control technology. Background technique: [0002] Bark beetle is the general term for insects of the family Scolytidae in the order Coleoptera. There are about 220 genera and about 6,000 species in the world. It is an important group of forest pests. Since the mid-1990s, spruce (Picea spp.) in western natural forest areas such as Qinghai Province in my country has been harmed by bark beetles, mainly Ips nitidus Eggers, resulting in a large number of tree death. [0003] Ips nitidus Eggers is mainly distributed in five provinces in western my country (Sichuan, Yunnan, Qinghai, Gansu, Xinjiang), and there is no report on its distribution abroad. It mainly harms Minjiang fir, spruce, Qinghai spruce, Tianshan spruce, western Sichuan spruce, alpine pine, etc. The bark beetle is small, lives in seclusion, and reproduces rapidly. Traditional methods are difficult to monitor and control, so it is easy to cause major disasters....
