Embodiment 1

[0005] Embodiment 1: be used for the aggregation pheromone attractant of attracting the oriental beetle, get (-)-barbecenol 85 milligrams, cis-verbenicenol 10 milligrams, trans-verbenicenol 5 mg mg. Without adding (±)-beetle dienol, mix each component evenly, and put it into a polyethylene plastic bag-type release carrier (lure) for use.

Embodiment 2

[0006] Embodiment 2: the aggregation pheromone attractant that is used to lure the oriental beetle, get (±)-barbecenol 300 mg, cis-verbecenol 150 mg, trans-verbecenol 50 mg mg, without adding (±)-beetledienol, mix the components evenly, and put them into bottle-type release carriers (lures) for use.

Embodiment 3

[0007] Embodiment 3: the aggregation pheromone attractant that is used to lure Odontoides orientalis, gets (-)-barbecenol 46 milligrams, cis-verbenicenol 30 milligrams, trans-verbenicenol 20 mg milligrams, (±)- 4 milligrams of bark beetle dienol, mix each component evenly, and put it into a rubber stopper-type release carrier (lure) for use.

Abstract

The invention provides an aggregated pheromone attractant for trapping oriental Ips, which is used to monitor and trap the oriental Ips and composed of 46%-85% of (plus / minus) bark beetle-enol or (minus)-bark beetle-enol, 10%-30% of cis-verbena enol, 5%-20% of trans-verbena enol, and 0%-4% of bark beetle-dienol. The components of the attractant are evenly mixed and cased into the polyethylene plastic bag-type, bottle-type, rubber-plug-type and other release carriers (induced core) for use. The invention belongs to the natural volatile organic substances and has stable structure and stable chemical properties of atmospheric pressure and ambient temperature; compared with conventional chemical control, the aggregated pheromone attractant is non-toxic, non-polluting and highly efficient, which is safe for the environment and the natural enemies; moreover, the invention can be used for species dynamic monitoring and production prevention and control of large-scale trapping in the oriental Ips emergence period and emergence areas.

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 attacked by Ips nitidus Eggers, Ips shangrila Cognato et Sun and Oriental Pseudipsorientalis (Wood & Yin) is the main pest of bark beetles, causing a large number of forest trees to die. [0003] Pseudips orientalis (Wood & Yin) is a recently revised genus of Pseudips orientalis, mainly distributed in several provinces in western my country (Qinghai, Sichuan, Yunnan), and has no foreign distribution at present. reports. It mainly harms Minjiang fir, spruce, Qinghai spruce, Tianshan spruce, western Sichuan spruce, alpine pine, etc. The bark beetle is smal...
