A kind of indoor feeding method of bean aphid
Technical field
The invention belongs to agriculture and forestry injurious insect technical field of biological control, is related to a kind of propagation method of natural enemy host, it is especially a kind of
The indoor feeding method of bean aphid.
Background technology
The key issue that the large-scale production of the natural enemy of aphid such as ladybug, wasp fly first has to solve is exactly the indoor numerous of natural enemy aphid
Plantation technology.Bean aphidAphis craccivoraKoch also known as aphis craccivora, Aphis medicaginis, are that a kind of growth and breeding is fast, thermal adaptability
Wide aphid, is that current natural enemy of aphid breeding uses a kind of most wide host, such as:Bean aphid breeding food aphid cecidomyiia is raised with Semen Viciae fabae SeedlingAphidoletes sp(Beijing City Agriculture and Forestry Institute), with Semen Viciae fabae raise bean aphid breeding harmonia axyridia(Tobacco company of Hubei Province)、
Bean aphid breeding aphidius gifuensis are raised with Semen Viciae fabae Seedling(Tobacco company of Yunnan Province)Deng above method all obtains national patent.By
Above-mentioned patent understands that Semen Viciae fabae is to breed a kind of the most frequently used host of bean aphid.But, Semen Viciae fabae is individual big, is not easy to soilless culture, numerous
Growing bean seedlings needed substantial amounts of seedling medium, and it is long to grow into the cycle that can be utilized for natural enemy from Semen Viciae fabae kind to bean aphid, up to 30 days left sides
The right side, this virtually increased the management cost of nursery and bean seedlings.In addition, the growing area of Semen Viciae fabae is not allowed mainly in the north in south
Easily obtain, such technology is subject to many limitations in south.Therefore, it is necessary to filter out it is a kind of easier, subject range more extensively with
And the bean aphid propagation method that cost is lower.
The content of the invention
It is an object of the invention to overcome not enough present in bean aphid propagation method at this stage, there is provided one kind operation is easier, suitable
Answer the scope lower bean aphid indoor propagation method of wide and cost.
In order to realize object above, the technical solution used in the present invention is as follows:
A kind of indoor feeding method of bean aphid, concrete operation step is:
(1)The cultivation of bean seedlings
1. the preparation of bean kind soak:Appropriate sterilized water is measured, a certain amount of medicament A is weighed, is poured in sterilized water and is stirred equal
It is even;
2. the immersion of bean kind:After bean kind is buied on market, bean kind is put in plastic tub, is shakeout, pour soak into, water level is higher than
Bean kind 2cm, soak time is 12h;The size of described plastic tub, chooses according to the bean kind quantity of immersion;
3. the accelerating germination of bean kind:Soaked bean kind is pulled out, is drained away the water, be together put into plastics together with the plastic tub for containing bean kind thin
In film bag, sealing, germination time is 2-3 days, until bean kind is taken out when growing the root of 3mm or so;Soak is filled with plastic squeeze bottle
It is good standby;
4. the cultivation of bean seedlings:The nursery material for being impregnated with moisture is put in the bottom of container for plant growth 1, be put into before by nursery material according to
The shapes and sizes of container bottom carry out cutting, then bean kind is paved with nursery material, do not overlap between bean kind individuality;Complete
Afterwards, container for plant growth is overlapped and is placed, the weight of a 500g or so is pressed on the container for plant growth of top, container is adjusted daily
Up and down order, until when the tender shoots for having 0.5cm length grows, removing weight, container for plant growth flat raft is placed in laboratory table;When
Bean aphid is inoculated with by when tender shoots grows to 3 ± 0.5cm;After cultivating 10d, with container for plant growth 2, educate by the method for above-mentioned container for plant growth 1
Seedling, the quantity of the nursery of container for plant growth 2 is 5 times of container 1.
(2)The inoculation of bean aphid
Bean aphid is gathered on leguminous plant and takes back interior, in moving into the container for plant growth 1 of tender shoots 3 ± 0.5cm of length, be placed in nursery material
It is upper;
(3)The expanding propagation of introduces a collection bean aphid
When covering with bean aphid in container for plant growth 1 bean seedlings, bean seedlings are cut into into segment, per section has aphid 50 ± 5, there will be aphid
Bean seedlings section move in the new container for plant growth 1 for cultivating tender shoots 3 ± 0.5cm of length, per container for plant growth 1 in move into bean aphid 500 ± 5;
(4)For breeding the bean aphid expanding propagation of natural enemy
Treat step(3)When covering with bean aphid on 1 bean seedlings in container for plant growth in the expanding propagation of introduces a collection bean aphid, it is put in container for plant growth 2
Support, in container for plant growth 1 is placed on support, 1 is taken out in container for plant growth after 1 day and is placed in new container for plant growth 2, weight
It is multiple 5 times, the bean aphid obtained for natural enemy is raised in container for plant growth 2.
Further, described medicament A is gibberellins, and the soak concentration of preparation is 0.5mg/L.
Further, described bean kind is Semen Ormosiae Hosiei.
Further, described container for plant growth 1 be Φ=10cm, the plastic tub of H=10cm;Described container for plant growth 2 is Φ
The plastic tub of >=20cm, H=10cm.
Further, described nursery material is bamboo fiber cloth, and specification is W=25cm, H=25cm.
Further, described support is that stainless steel frame specification is Φ=9cm, H=4cm.
The advantage and good effect of the inventive method:
1st, aphid is bred using this method, to the less demanding of humiture, the requirement to illumination is not also high, it is not necessary to extra to increase
Light source, reduces management cost;
2nd, this method replaces Semen Viciae fabae from Semen Ormosiae Hosiei, because Semen Ormosiae Hosiei is wide compared with Semen Viciae fabae in the planting range of China, it is easier to obtain,
Emerge neat.
3rd, from fiber cloth as medium nursery, suitable Semen Ormosiae Hosiei belongs to Semen Phaseoli type bean kind nursery and uses this method, can be with
Saving the such as Semen Viciae fabae nursery of Semen sojae atricolor type bean kind must use a large amount of seedling mediums, save seedling cost;
4th, this method utilizes excessive growth principle of the plant seed under the conditions of low-light, the reasonable employment of auxin is added, so as to control
The growing height of Semen Ormosiae Hosiei Seedling processed.
5th, the Semen Ormosiae Hosiei for using of this method reaches from sowing and can be inoculated with aphid, it is only necessary to the 4d times, from inoculation aphid
Aphid is covered with to bean seedlings and also only need to 6d, half is saved compared with the time that aphid is bred with Semen Viciae fabae Seedling many, with preferable economy
Benefit and social benefit.
