Description

Needlebush insect broad spectrum activity attractant

Technical field

The present invention relates to needlebush insect broad spectrum activity attractant, especially be applicable to the attractant of luring insects in Ganlei such as Monochamus alternatus.

Background technology

Along with the accelerated development of trade globalization, the spread speed of various pests is also accelerated thereupon.At present, China's inspection and quarantine system all intercepts and captures on imported timber and wood package materials a large amount of external forest pests is arranged every year.Importing into of a large amount of external forest pests; Harm to China's forest resourceies increases the weight of day by day, and according to forest department's statistics, the external forest pest of China area is taken place every year reaches more than 2,000 ten thousand mu; The up to ten million strains of trees that cause death, loss every year that forestry is caused is up to more than 600 hundred million RMB.

The monitoring trapping of port forest pest is to prevent external pest invasion and control and alleviate the important step of forest pest harm; But; Still do not have a kind of cost-effective forest pest wide spectrum lure at present both at home and abroad, be difficult to port and woodland pest effectively supervised and catch.The monitoring trapping of port forest pest is to prevent external pest invasion and control and alleviate the important process of forest pest harm.But, still do not have a kind of cost-effective forest pest wide spectrum lure at present both at home and abroad.We have designed a kind of efficiently, economical through port and woodland monitoring experiment for this reason, are fit to the needlebush insect broad spectrum attractant of port monitoring.

Summary of the invention

The present invention provides a kind of needlebush insect broad spectrum activity attractant of suitable port monitoring, and this attractant cost is low, and the needlebush class pest is had extremely strong allure, can realize quick trapping.

Needlebush insect attractant of the present invention is formed by active compound and the configuration of solvent absolute ethyl alcohol; Active compound is made up of australene, nopinene, amphene, citrene, isolongifolene, trans-caryophyllene, turpentine oil, terpinolene and β-phellandrene, and the weight percentage of each component is in the said active compound:

Australene 40～50%

Nopinene 20～25%

Amphene 2.5～3.2%

Citrene 11～13%

Isolongifolene 4.5～5.2%

It is trans-caryophyllene 5～6%,

Turpentine oil 2.5～3.5%,

Terpinolene 2.5～3.5%,

β-phellandrene 0.8～1.2 %;

Said solvent absolute ethyl alcohol is 0.5～1.5 times of said active compound matter gross weight.

In the said active compound, the best percentage composition of various components is:

Australene 45%, nopinene 22%, amphene 3%, citrene 12%, isolongifolene 5%, trans-caryophyllene 6%, turpentine oil 3%, terpinolene 3% and β-phellandrene 1%.

The manufacturing approach of attractant: each component is added in the container according to a certain ratio, add absolute ethyl alcohol, fully can gets final product behind the mixing.

Since the volatile materials in the host plant the adult host search of insects such as Monochamus alternatus, supplement the nutrients and the environment location of behavior such as lay eggs in play an important role; Therefore the present invention is that the 11 kinds of further anaerobies fermentation of monoterpene products are analyzed to the domestic volatile constituent that is prone to six kinds of timber such as susceptible pine kind black pine, masson pine, cdear and China port main body entrance pesudotsuga taxifolia, larch, kahikatea, dragon spruce, Chinese hemlock spruce, fir; Filter out and the effective single material of harmful insect such as to resemble through cross-over experiment methods such as chemistry, entomology, plant physiology to Monochamus alternatus, bark beetle, flatheaded borer, loose knurl; Further filter out the maximum single material of reaction; Undertaken composite by its average content in volatile matter; Placing woodland to carry out the field in the composite mixture that goes out lures the collection test, filters out the best combination formula of effect.

EAG determination of activity and woodland are used repeated validation through the laboratory; Attractant of the present invention is obvious to the attracting action of needlebush insect; Be superior to existing attractant; Easy to use, cost is low, pollution-free, satisfactory for result, be the needlebush insect attractant of a kind of efficient, economy, wide spectrum, be particularly suitable for using in the monitoring of port or woodland.

The concrete beneficial effect of this attractant is following:

(1) Monochamus alternatus imago is had extremely strong attractive effect, to loose knurl resemble, masson pine angle shin resembles, cuts tail material bark beetle that higher attractive effect is arranged, and kind of insect surplus the coleoptera 20 is all had good attractant effect; The experiment of insect spot such as a plurality of Monochamus alternatus shows that can reach hundreds of head insect with a small amount of attractant trapping every day amount of the present invention, effect is all good through Jiangsu Province.

(2) the present invention generates and easy to use, with low cost, ecological safety, and the pine tree area all can be applicable.

(3) the present invention is fit to the external forest pest monitoring use of inward timber port.

(4) term of validity of the present invention is longer, and general woodland adds medicine one time, and the term of validity is more than 15 days.
