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
Affiliated technical field:
The invention belongs to the control of insect technology.
Background technology:
Bark beetle is the general name of coleoptera (Coleoptera) Scolytidae (Scolytidae) insect, and the whole world has 220 to belong to approximately, about 6000 kinds, is important monoid in the forest pest.Twentieth century the mid-90 begins, western natural forest area dragon spruces (Picea spp.) such as China Qinghai Province suffer that with light stern octadentate bark beetle (Ips nitidusEggers) tooth bark beetle [Pseudipsorientalis (Wood ﹠amp is intended in Shangri-la tooth bark beetle (Ips shangrila Cognato et Sun) and east; Yin)] be main bark beetle harm, cause the forest mortality.
Tooth bark beetle [Pseudips orientalis (Wood ﹠amp is intended in east; Yin)] be a kind of of the recent plan tooth bark beetle genus of revising, mainly be distributed in several provinces and regions (Qinghai, Sichuan, Yunnan) in China western part, still not having external the distribution at present and reporting.The main harm Abies recurvata, dragon spruce, thickleaf spruce, tianshan mountain spruce, balfour spruce, high illawarra mountain pine etc.This bark beetle individuality is little, life is hidden, breeding is rapid, and conventional method is difficult to monitoring and control, thereby causes great disaster easily.Because the disguise that causes harm of bark beetle, chemical control is difficult to prove effective when insect pest takes place, and chemical control also is well-known to the destruction of ecotope.Because the harm of this worm is on the rise, and has been subjected to many researchers' attention.Recently, Liu Li etc. have reported east in detail and have intended tooth bark beetle, Shangri-la tooth bark beetle and light stern octadentate bark beetle basic biology and ecological characteristics (Liu Li etc., 2007) in the dragon spruce natural forest.In recent years, Qinghai Province forest department also test once utilize known tooth bark beetle belong to aggregation pheromone composition and various compound mode test in the open air in the potential pheromone attractant of screening, but do not obtain any substantive breakthroughs as yet.Dragon spruce be the China's western region forest mainly build group seeds, ecological and economic worth is very big, if should zone natural forest resource by forestry pest destruction based on bark beetle, its consequence is hardly imaginable.Intend the harm of tooth bark beetle to forest in order to control east as early as possible, utilize bionics principle, take insect pheromones baiting technique, the aggregation pheromone attractant of researching and developing this insect has targetedly become the task of top priority.
Summary of the invention:
At the problem of above-mentioned existence, the present invention proposes the aggregation pheromone attractant that is used for attracting east plan tooth bark beetle, be used for monitoring and trapping that the tooth bark beetle is intended in east.Adopt male worm hindgut solvent extraction and chemical analysis means, identify the aggregation pheromone system that the tooth bark beetle is intended in east in the world first.This bark beetle aggregation pheromone comprises following four kinds of compositions (natural secretion percentage range): (-)-bark beetle enol (60-80%), cis-verbenol (10-20%), trans-verbenol (5-10%) and (±)-bark beetle dienol (0-4%).The present invention is achieved through the following technical solutions: be used for the aggregation pheromone attractant that attracting east is intended the tooth bark beetle, it is characterized in that it is grouped into by following one-tenth: (±)-bark beetle enol or (-)-bark beetle enol 46%～85%, cis-verbenol 10%～30%, trans-verbenol 5%～20%, (±)-bark beetle dienol 0%～4%.The each component of attractant prescription provided by the invention is evenly mixed, pack into and use in vinyon pocket type, the release vehicles (luring core) such as bottle formula, rubber stopper formula, its effective rate of release is controlled at respectively: (±)-bark beetle enol or (-)-bark beetle enol 0.2-10 mg/day, cis-verbenol 0.1-5 mg/day, trans-verbenol 0.1-3 mg/day, (±)-bark beetle dienol 0-1 mg/day.Aggregation pheromone attractant component provided by the invention belongs to natural volatile organic matter, its Stability Analysis of Structures, chemical property is stable under the normal temperature and pressure, compares with the conventional chemical control, have nontoxic, pollution-free, efficient, to the characteristics of environment and natural enemies security.Each component provided by the invention is bought on market easily, and preparation is simple.The attractant that this invention provides can be arranged in the dissimilar bark beetle trappers, is used for east and intends tooth bark beetle emergence period, generating region, population dynamic monitoring and large tracts of land trapping control.

Embodiment 1: is used for the aggregation pheromone attractant that attracting east is intended the tooth bark beetle, gets (-)-85 milligrams of bark beetle enols, and 10 milligrams of cis-verbenols, trans-5 milligrams of verbenols.Do not add (±)-the bark beetle dienol, each component is mixed, use in the vinyon pocket type release vehicle (luring core) of packing into.
Embodiment 2: be used for the aggregation pheromone attractant that attracting east is intended the tooth bark beetle, get (±)-300 milligrams of bark beetle enols, 150 milligrams of cis-verbenols, trans-50 milligrams of verbenols, do not add (±)-the bark beetle dienol, each component is mixed, use in bottle formula release vehicle (luring core) of packing into.
Embodiment 3: be used for the aggregation pheromone attractant that attracting east is intended the tooth bark beetle, get (-)-46 milligrams of bark beetle enols, 30 milligrams of cis-verbenols, trans-20 milligrams of verbenols, 4 milligrams of (±)-bark beetle dienols, each component is mixed, use in the rubber stopper formula of packing into the release vehicle (luring core).
Embodiment 4: be used for the aggregation pheromone attractant that attracting east is intended the tooth bark beetle, get (±)-390 milligrams of bark beetle enols, 67 milligrams of cis-verbenols, trans-33 milligrams of verbenols, 10 milligrams of (±)-bark beetle dienols, each component is mixed, use in bottle formula release vehicle (luring core) of packing into.
