Abstract

The invention discloses a kind of methods using pheromones compound and ladybug joint prevention and treatment phytophthira pest, using Aphid Alarm Pheromone, plant Odors of green leaves as basis, slow-released carrier is made by different ratio, the trans-beta-farnesene released not only can directly walk quickly and keep away aphid, it can be also set to generate disturbance, improve ladybug discovery and feeding aphid effect, and the plant Odors of green leaves being added appropriate can adjust the stability of alarm element release, and increase it and discharge the lasting period, to achieve the purpose that walk quickly and keep away and catch and kill aphid.Controlling experiment proves; in the case where using the present invention; 25%-45% can be improved in control efficiency when than ladybug or pheromones preventive effect is used alone; the present invention can reduce the usage amount of chemical pesticide; it reduces environmental pollution; so that aphid is not likely to produce drug resistance, protect bio-diversity and nature enemy in amount, opens up pheromones in the new tool in pest control field.

Description

A method of combining prevention and treatment phytophthira pest with ladybug using pheromones compound
Technical field
The invention belongs to agricultural insect pest's Prevention Technique fields, and in particular to a kind of to be combined using pheromones compound with ladybug The method for preventing and treating phytophthira pest.
Background technique
Aphid, also known as aphid, aphid are a kind of plant-feed insects, including all under Aphidoidea (also known as aphid Superfamily) Member.About 4400 kinds of a total of 10 sections of the aphid having now been found that, wherein majority belongs to Aphidiadae.Aphid be also on the earth most One of disruptive pest.Wherein about 250 kinds are to endanger serious pest for agriculture and forestry and horticulture.Aphid is numerous Grow strong with adaptive faculty, conventional chemical control method is all difficult to obtain the effect of radical cure, and a large amount of uses of chemical pesticide make agriculture Industry pest generally produces drug resistance.How to efficiently control it to cause harm, while reducing chemical pesticide environmental pollution, and to day Insect infestations are opposed, are a urgent problems to be solved.With the rapid development that Chemical ecology of insect is studied, insect pheromone is anti- Technology is controlled to be widely used in the comprehensive treatment of pest.
Aphid can secret out of thick liquid, i.e. aphid alarm signal when being preyed on by natural enemy or meeting with other interference from its cornical Breath element, this Volatile infrochemicals as a kind of chemical communication substance, can cause the warning of aphid around, stop feeding, It is in a tumult and flees danger the behavior of environment.Bowers etc. (1972) is separated identify the trans- β-Fa Ni of Aphid Alarm Pheromone for the first time Alkene (E- β-farnesene, E β F).E β F is a kind of sesquiterpenoids substance, be most aphids alarm pheromones it is main even Sole component (Bowerset al., 1972; Francis et al., 2005), since E β F action time is short and unstable It is fixed, it is difficult to be applied in agricultural, therefore explore E β F to become domestic and international research hotspot in Field information technology.Many plants In be rich in E β F ingredient, pass through classification purify can get high concentration essential oil, such as LabiataeHemizygia petiolataE in plant β F component content is up to 70% or more (Bruceet al., 2005);UmbelliferaePimpinella khorasanicaPlant E β F ingredient also has higher content (Askari in stem, flower and seedet al., 2013).E β F is not only present in aphid alarm In hormone and one of many Secondary metabolites.Although using the high concentration essential oil slow release method containing E β F to pea AphidAcyrthosiphon pisum(Bruce et al., 2005), vegetable aphid (Cui et al., 2012b) and wheat aphid (Zhou, 2012) there is certain control action in prevention and control, but this is only avoidance effect of the one-component to aphid, the lasting period is short, The mode of action is unstable, does not carry out the control in population quantity to pest, and the present invention is using Aphid Alarm Pheromone, day The mode that enemy, plant Odors of green leaves act synergistically carries out bionomic control to aphid, plays good control effect.And It yet there are no and apply Aphid Alarm Pheromone E β F and Odors of green leaves to the anti-relevant report to eliminate aphis of natural enemy ladybug.
Summary of the invention
The purpose of the present invention is to provide a kind of to combine the side for preventing and treating phytophthira pest using pheromones compound with ladybug Method is a kind of using the method for improving ladybug predation aphid effect containing the compound of pheromones and plant Odors of green leaves, using such as Lower technical solution is realized:
A method of combining prevention and treatment phytophthira pest, specific implementation step with ladybug using pheromones compound are as follows: Slow-released carrier is hung among aphid group and is higher by effect 2 ~ 5cm of target, each slow-released carrier spacing 8m ~ 10m;Wooden dipper will be planted simultaneously It is released to aphid group's harm place;Prey on ladybug in aphid accumulation process.
The pheromones compound is by trans-beta-farnesene, cis- 3- hexenol and cis- 3- hexenyl acetate according to mass ratio 4 ~ 7:2 ~ 4:1 ~ 3 is formed.
The ladybug is one of harmonia axyridia, Propylaea japonica, coccinella septempunctata or coccinella undecimpanctata;The aphid is cotton One of aphid, rhopalosiphum padi, hyalopterus arundinis or turnip aphid.
The pheromones compound the preparation method comprises the following steps: components in certain proportion each in pheromones compound is dissolved in n-hexane In, it is configured to certain density slow-released carrier solution, and the antioxidant 2,6-di-tert-butyl p-cresol and purple of 0.5mg is respectively added Outer smooth adsorbent ESCALOL 567, be encapsulated in it is spare in PVC bag, containing compound in each slow-released carrier The amount of object is 4mg.
It is a further object to provide the methods in improving vegetables or crop in the anti-effect that eliminates aphis of ladybug Application.Aphid alarm element and Odors of green leaves are combined into optimal proportion and improve the slow of the anti-effect that eliminates aphis of ladybug by the present invention Release carrier;Carry out slow-released carrier in crop or vegetables field aphid high-incidence season and ladybug discharge simultaneously, with reach control aphid, Protect natural enemies and the purpose for maintaining bio-diversity.
A kind of method for combining prevention and treatment phytophthira pest with ladybug using pheromones compound provided by the invention, with aphid Alarm pheromones, plant Odors of green leaves are basis, slow-released carrier are made by different ratio, the trans- β-Fa Ni released Alkene not only can directly walk quickly and keep away aphid, so that it is generated disturbance, raising ladybug finds and feeding aphid effect, and the plant being added Object Odors of green leaves appropriate can adjust the stability of alarm element release, and increase it and discharge the lasting period, walk quickly and keep away and catch to reach The purpose of killing aphids.Controlling experiment proves, in the case where using the present invention, prevents when than ladybug or pheromones preventive effect is used alone Controlling effect can be improved 25%-45%, and the present invention can reduce the usage amount of chemical pesticide, reduce environmental pollution, and aphid is made to be not easy to produce Raw drug resistance, protects bio-diversity and nature enemy in amount, has opened up pheromones in the new tool in pest control field.
