Description

A method of trapping coccinella septempunctata oviposition
Technical field
The invention belongs to insect Cultivating techniques fields, and in particular to a method of trap coccinella septempunctata oviposition.
Background technique
Aphid is a kind of agriculturally very harmful pest, all brings irreversible damage to plant and environment, no matter Greenhouse all once caused no small disaster still in crop field.Currently, to the prevention and treatment of aphid mainly based on pesticide control, although Significant effect but inevitably cause due to chemical pesticide dosage is excessively high and bring great chemical drug pollution, cause Secondary hazards.
Coccinella septempunctata (Coccinella septempunctata L.) is one of Dominant Natural Enemies insect of aphid, seven-star wooden dipper Eimeria is on the chief crops such as wheat, cotton, oil plant and vegetables in coleoptera Coleoptera, Coccinellidae Coccinellidae The important predator of aphid.Research both at home and abroad is it was demonstrated that being eliminated aphis using coccinella septempunctata is that a kind of fabulous biology is anti- Control mode.Application chemical pesticide can be effectively reduced with the bio-control method that worm controls worm to pollute to environment bring and to personal strong The harm of health bring, has important ecological significance.With the raising of biological control commercial applications degree, about predatism wooden dipper The research of worm growth and development, population large-scale breeding and application security etc. has become new research hotspot.
In the indoors artificial method for breeding of existing coccinella septempunctata, mature system method can not enable coccinella septempunctata steady Fixed, the good character of holding successive propagation gets off.Be constantly present in current method coccinella septempunctata can complete the history of life, But the problem of fecundity is not strong, lacks the research to egg laying amount method, can not achieve a large amount of continuously rearings.The test worm of coccinella septempunctata It is acquired by field, without the stable worm sources of artificial continuous multi-generation raising, limits the research work to it, also limit it Release application is carried out in field as natural enemy insect.
Early-stage study shows that it is a kind of relatively good breeding seven-star that black bean aphid raising coccinella septempunctata is cultivated using indoors artificial The method of ladybug.Wherein, the factors such as environment photoperiod, varying environment color have the spawning habit and egg laying amount of coccinella septempunctata It significantly affects.And the method that coccinella septempunctata is effective, concentrates oviposition can be trapped, the extensive artificial propagation for coccinella septempunctata It plays an important role, provides premise for Field information coccinella septempunctata.
Summary of the invention
For this purpose, technical problem to be solved by the present invention lies in provide a kind of method for trapping coccinella septempunctata oviposition.
In order to solve the above technical problems, a kind of method for trapping coccinella septempunctata oviposition of the present invention, that is, include that will lure Acquisition means, which are placed in coccinella septempunctata dependent insect cage, carries out the step of trapping oviposition;
Described to trap device, including open oviposition container, the oviposition container is internally provided with the partition with aperture, makes The oviposition container is separated into upper layer and traps space and lower layer and lays eggs space;
The upper layer traps and is provided with funnel-form trap in space, and the open end of the trap, which is provided with to contain, traps material The lure of material, the tubule end of the trap pass through the aperture and protrude into the oviposition space;
Lower layer's oviposition is equipped with oviposition carrier in space.
The trap material is the pea seedlings for being loaded with pea tail reparing aphid.
The root of the pea seedlings is provided with immersion absorbent cotton.
The external sheath of the immersion absorbent cotton has preservative film.
The quantity of the pea tail reparing aphid is 180-220 heads/plant of pea seedlings.
The oviposition carrier is PE bags of dark color.
The oviposition carrier is black PE bags.
The oviposition carrier is that black is PE bags smooth.
It is described oviposition carrier with a thickness of 0.1-0.2mm.
The injected volume of the pea tail reparing aphid is 500-600:1 with the quantity ratio wait trap oviposition ladybug.
In order to further increase the gathering effect to coccinella septempunctata oviposition, lure of the present invention containing described in addition to trapping Outside material, it is additionally provided with and traps matrix;
Specifically, the matrix that traps includes tea powder, cereal starch, water and agar, the tea powder, cereal starch, water and The mass ratio of agar is 10-15:8-12:100:2.
Preferably, the mass ratio of the tea powder, cereal starch and water is 12:10:100:2.
Specifically, the tea powder includes green tea powder, white tea powder and/or olong tea powder.
More preferably, the tea powder includes green tea powder, white tea powder and the olong tea powder that mass ratio is 2:1:1.
Specifically, the cereal starch includes cornstarch and/or wheaten starch.
More preferably, the cereal starch includes the cornstarch and wheaten starch that mass ratio is 1:1.
The method for trapping matrix is prepared the invention also discloses a kind of, that is, includes taking a selected amount of tea powder, paddy The step of object starch, water and agar are mixed.
The method of the present invention for trapping coccinella septempunctata oviposition is to trap material to be loaded with the pea seedlings of sufficient pea tail reparing aphid Material places it in oviposition container using coccinella septempunctata to the taxis of aphid and carries out trapping oviposition, have and significantly trap effect With, coccinella septempunctata can be trapped together, be conducive to its aggregation oviposition;And with high smooth with a thickness of 0.1- of quantity of laying eggs PE bags of black of 0.2mm are oviposition carrier, effectively increase the spawning rate and the rate of recovery of coccinella septempunctata, efficiently solve seven-star wooden dipper Worm egg laying amount and the not high problem of the ovum rate of recovery, guarantee it its population colonization plays a significant role.
The lure material of the present invention for trapping device, it is contemplated that number of the growth conditions of pea seedlings for pea tail reparing aphid Amount and survival rate have great influence, and pea tail reparing aphid quantity influences the congregational rate and egg laying amount of ladybug, in view of wet Spending has decisive role to the fresh of holding pea seedlings, therefore is soaked in the pea seedlings of trap material with absorbent cotton in the present invention The method for surrounding root afterwards, being then coated with one layer of preservative film again prevents moisture on absorbent cotton from evaporating, to guarantee the health of pea seedlings Growth, to guarantee that aphis population is stablized on pea seedlings.
In order to improve the gathering effect of described device, it further joined to help to improve in lure of the present invention and trap Effect traps matrix, and the matrix that traps adds water and agar that solid state substrate is made using selected tea powder, cereal starch as raw material Shape effectively increases the gathering effect of coccinella septempunctata using the smell effect of Adult Coccinella Septempunctata.
The method of the present invention for trapping coccinella septempunctata oviposition combines become chromatic effect and the smell effect of Adult Coccinella Septempunctata It should propose and new trap oviposition method, it is ensured that all adults can be laid eggs by concentrating, and lay eggs mediator and adult trap Device is used cooperatively, and reduces ladybug and ovum is produced in other positions, and the especially hidden, position that is not easily recycled is improved into It is scarce with taking a lot of work, cannot reuse to efficiently solve currently used coccinella septempunctata oviposition method for the rate of recovery of worm oviposition Point, to realize that the factorial production ladybug provides a new approach.
