Abstract

The invention discloses one kind is little to pass through smaller green leaf hopper prevention and controls, prevention and control tea lesser leafhopper is combined with tea plant volatiles inducing agent by blue LED lamp, the blue LED lamp of some 0.5W 1W is specifically installed on lamp bracket, wavelength 450nm 490nm, plain single sonorous stone Huang insect-sticking plate is hung with below LED, tea lesser leafhopper lure on insect-sticking plate, is placed with.The present invention is integrated with and traps the advantage trapped with chemistry to the little smaller green leaf hopper physics that passes through, and is favorably improved preventive effect of the tea place to tea lesser leafhopper.

Description

One kind is little to pass through smaller green leaf hopper prevention and controls

Technical field

The invention belongs to agricultural technology field, be related to LED and inducing agent combination it is little pass through in smaller green leaf hopper preventing and treating should With, and in particular to a kind of tea lesser leafhopper prevention and controls.

Background technology

Tea lesser leafhopper, or claim little to pass through smaller green leaf hopper Empoasca (Matsumurasca) onukii Matsuda, half wing Mesh, Cicadellidae are commonly called as leafhopper, leaf springtail etc., and each product tea in the whole nation is saved, there is generation in autonomous region, is China's tea place Severe pests One of.It is little to pass through smaller green leaf hopper 1 year 8-12 generations, and generation overlap, And Development of Tea Shoot of seriously causing harm occur, aggrieved Camellia sinensis bud-leaf rolls up, Hardening, blade tip and leaf margin are reddish brown dried-up, and bud tip poor growth is extremely serious to tea yield and qualitative effects.

The method of preventing and treating tea lesser leafhopper mainly has at present：(1) pluck in time；(2) light trap.Using smaller green leaf hopper into Worm phototaxis feature, carries out light trap or colour table trapping to adult；(3) adult is trapped and killed using gyplure；(4) winter clear garden； (5) chemical control.Can select 1000 times of liquid of 10% imidacloprid, 2000 times of liquid or 25% deltamethrin milk oil to be prevented and treated, or use 0.3% 100 times of matrine, 0.5% jervine 200 are prevented and treated again.

Although light trap can reduce adult quantity to a certain extent, common trap lamp selectivity is poor, to day Enemy damages larger, and the penetration power of common trap lamp light is not high.Use information element trapping adult is a preferable method, but information Between sibling specieses, in different geographical obvious difference, isolating and purifying for pheromone identifies more difficult to the molecular structure of element, price Costliness, using being above restricted.The use of synthetic pesticide brings very serious environment and health problem, botanical pesticide achieved with Good result, but the requirement of Camellia sinensis plant protection still can not be fully met merely by a few botanical pesticide.

Based on food safety and the needs preserved the ecological environment, develop environmentally safe material and substitute traditional pesticide Method to control plant pest is widely paid close attention to, using some environmental safeties higher material such as phytovolatilization Thing is administering the important research direction that insect is this field.

Rely primarily on specific plant volatile to position during insect search of food, our research finds Camellia sinensis in nature Micro volatile material can be discharged under growth conditionss, further research confirms cis- hexenol, suitable 3- hexenyl acetates, sieve The particular combination of Le alkene and linalool is the Main Basiss of the orthoselection that smaller green leaf hopper takes food Camellia sinensis tender tip.Color is leafhopper choosing Select another important evidence of host, colour table technology is obtained in tea place and extensively applied, but it is aging because of colour table under field condition And contamination, color can morph, and using the LED not only stable luminescence of accurate light modulation, brightness is high, and the penetration power of light It is relatively strong, propagate farther out, just mutually supplement with the effect of tea plant volatiles.

The content of the invention

Goal of the invention：To realize above-mentioned technical purpose, present invention offer one kind is little to pass through smaller green leaf hopper prevention and controls.

Technical scheme：To realize above-mentioned technical purpose, the little of the present invention passes through smaller green leaf hopper prevention and controls, by blue-ray LED Lamp combines prevention and control tea lesser leafhopper with tea plant volatiles inducing agent.

Specifically, comprise the steps：The blue LED lamp of some 0.5W-1W, wavelength 450nm- are installed on lamp bracket 490nm, hangs with plain single sonorous stone Huang insect-sticking plate, tea lesser leafhopper lure is placed with insect-sticking plate below LED.

Wherein, it is described it is little pass through smaller green leaf hopper lure and be made by the steps obtain：

(1) will be tea plant volatiles cis- hexenol, cis- 3- hexenyl acetates, ocimene, linalool each molten with normal hexane Solution of the solution into 10mg/L, then the solution to form 1mg/L is dissolved with paraffin；

(2) the various tea plant volatiles solution of the 1mg/L that step (1) is obtained by cis- hexenol 1-10 parts, cis- 3- oneself Alkene acetass 10-50 parts, ocimene 0.5-2 parts, the volume ratio mixing of linalool 0.5-10, obtain tea plant volatiles inducing agent, Tea plant volatiles inducing agent is adsorbed in rubber carrier, forms tea lesser leafhopper lure.

Beneficial effect：The invention discloses one kind to combine prevention and control tea with tea plant volatiles inducing agent by blue LED lamp little The method of greenery Cicadae, realizes the little purpose passed through smaller green leaf hopper and minimize to natural enemy damage of efficient selective aggregation.

Specific embodiment

According to intensity and test pressure request that smaller green leaf hopper is expected to occur, device is prevented and treated by per mu of 2 groups of tea lesser leafhopper Density arranges that in tea place the described little smaller green leaf hopper preventing and treating device that passes through hereinafter is also called trap lamp.

The tea lesser leafhopper preventing and treating device of the present invention includes that 5～8 blue LED lamps 1 and tea lesser leafhopper trap unit, blue Light LED 1 is installed on lamp bracket 2；The little smaller green leaf hopper inducing agent unit that passes through includes a plain single sonorous stone Huang insect-sticking plate 3, plain single sonorous stone Huang mythimna separata Plate two sides scribbles viscose, and hangs on below blue LED lamp, and one jiao of plain single sonorous stone Huang insect-sticking plate is provided with and little passes through smaller green leaf hopper lure 4, it is little pass through smaller green leaf hopper lure and be adsorbed on rubber carrier by tea plant volatiles inducing agent prepare.

Embodiment 1

(1) the cis- hexenol of Camellia sinensis essential oil, cis- 3- hexenyl acetates, ocimene, linalool is each with n-hexane dissolution Into the solution of 10mg/L, then the solution to form 1mg/L is dissolved with paraffin.

In June, (2) 2015, with 2 parts of the cis- hexenol of Camellia sinensis essence oil solution 1mg/L, the cis- 3- hexenes acetic acid of 1mg/L 12 parts of ester, 1.6 parts of the ocimene of 1mg/L, the volume ratio mixing of 5 parts of the linalool of 1mg/L obtain inducing agent, inducing agent absorption In rubber stopper, lure is formed, lure is placed on plain single sonorous stone Huang insect-sticking plate.Insect-sticking plate is hung on LED frame, on each LED frame 8 blue LED lamps are provided with, one group of trap lamp are formed, per mu is placed 2 groups of trap lamps, but remain power-off.

Insect-sticking plate is removed after one week, the worm of lure treatment group and the insect-sticking plate adhesion of matched group (without lure process) is checked Son, as a result averagely inspects 106 leafhopper adults with lure Huang plate, averagely inspects 33 leafhopper adults without lure Huang plate.
