The utility model achieves the beneficial effects that: the dropped fruits collecting net can be used for collecting dropped fruits concentratedly by an agricultural producer conveniently; can be applied in the biological prevention and control to citrus fruit flies, because the net can breed parasitic wasps continuously which are the natural enemy of citrus fruit flies; also achieves the advantages of simple structure and convenient operation.
Description
Technical field
The utility model relates to the take precautions against natural calamities corollary apparatus of harm reduction of a kind of agricultural production, particularly a kind of shedding collecting net.
Background technology
Citrus fruit fly
Bactrocera dorsalis(Hende1) be the dangerous quarantine pest insect in a kind of world, host range is wide, and along with the adjustment of climatic variation, pattern of farming and the increase of international trade, its hazard area enlarges gradually, already brings serious economy loss for fruits and vegetables.Citrus fruit fly lays eggs and causes harm in fruit, causes that fruit rots, shedding, has a strong impact on the output and the quality of fruit.The shedding of band worm lures the collection citrus fruit fly to lay eggs and gets food, has aggravated its harm in the orchard.In the measure of integrated control citrus fruit fly, the peasant extracts killed fruit in the past and picks up the ripe fruit that lands, and concentrates buriedly, and sprays insecticide, and prevents from that larva from burying to pupate.But the method for buried shedding is not only time-consuming but also require great effort, and also can kill the natural enemy parasitic wasp of citrus fruit fly simultaneously.
Find the parasitic citrus fruit fly of multiple parasitic wasp energy at present, adhered to Aphidiidae, Encytidae, gold chalcid fly etc. separately.External more common Braconidae natural enemy has two classes: a class be ovum and larva parasitic wasp as
Biosteres arisanus,
B.
Vandenboschi,
Psyttalia incisiThe parasitic wasp of another kind of larva and pupa as
Diachasmimorpha longicaudata,
D.
Tryoni,
Tetrastichus giffardianusObtain remarkable effect for the generation that utilizes parasitic wasp control citrus fruit fly with causing harm, and can large-area applications, now more and more be subjected to the attention and the favor in countries in the world or area, become the main trend that citrus fruit fly is administered in the world.
The utility model content
The utility model provides a kind of shedding collecting net, to solve prior art time-consuming effort again in the measure of integrated control citrus fruit fly, the technical problem that also can kill the natural enemy parasitic wasp of citrus fruit fly simultaneously.
The utility model adopts following technical scheme:
A kind of shedding collecting net, described collecting net comprises close-connected upper part and end portion, the mesh aperture of upper part is greater than the mesh aperture of end portion.
As a kind of preferred version, the mesh aperture of described upper part is greater than the chest of the natural enemy parasitic wasp of citrus fruit fly and belly mean breadth and less than citrus fruit fly adult chest and belly mean breadth, the mesh aperture of described end portion is less than citrus fruit fly larva polypide mean breadth.
As a kind of preferred version, the mesh aperture of the upper part of described collecting net is for being less than or equal to 2.0mm, and the mesh aperture of described end portion is for being less than or equal to 1.0mm.
As further preferred version, the mesh aperture of the upper part of described collecting net is 2.0mm, is 10 orders, and the mesh aperture of described end portion is 1.0mm, is 20 orders.
As a kind of preferred version, the height of described end portion is greater than the average jumping height of citrus fruit fly mature larva.
As further preferred version, the height of described end portion is greater than 10cm.
As further preferred version again, the height of described end portion is 50cm.
As a kind of preferred version, described end portion is a cube geometry, and the upper part is the camber structure.
As further preferred version, described end portion comprises many lower floor supports and is looped around the outer lower net material of four lower floor supports that the upper end of many lower floor supports is connected with removable lateral frame, forms cubic structure.
As further preferred version, described upper part comprises the tent cribbing, and be looped around the outer upper wire material of tent cribbing, and described tent cribbing is the stereochemical structure that many arc supports are formed, the lower end of tent cribbing is connected with removable lateral frame.
As a kind of preferred version, described upper part also is provided with slide fastener.
The utility model can make things convenient for the shedding of agricultural producer's centralized collection, can be applied in its natural enemy parasitic wasp of sustainable breeding in the citrus fruit fly biological control, and is simple in structure, easy to operate.
Description of drawings
Fig. 1 is the whole structure figure of shedding collecting net.
Among Fig. 1. 1. upper wire material, 2. nylon zipper, 3. lower net material, 4. lower floor support, 5. fixed part, 6. removable lateral frame, 7. tent cribbing.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in the figure, the whole collecting net of present embodiment is the design of folding tent formula, and end portion is a cube geometry, and the upper part is the camber structure.End portion comprises many lower floor supports 4 and is looped around four lower floor supports 4 lower net material 3 outward that the upper end of many lower floor supports 4 is connected with removable lateral frame 6, forms cubic structure.The upper part comprises tent cribbing 7, and is looped around the upper wire material 1 outside the tent cribbing 7, and described tent cribbing 7 is the stereochemical structure that many arc supports are formed, and the lower end of tent cribbing 7 is connected with removable lateral frame 6.
Fixed part 5 is that the joint part of lower floor support 4 and removable lateral frame 6 is fixed, launch tent cribbing 7 after, with removable lateral frame 6 one section fixed part 5 of packing into again, stretch out lower floor support 4 again and be fixed in the face of land.After installing the shedding collecting net, open the nylon zipper 2 input sheddings and the fruit that is injured.
Present embodiment is the sealed collecting net of loam cake of the no end, and special net materials adopts high density polyethylene (HDPE) (HDPE), and the interpolation antiaging agent is weaved through wire drawing and formed, and reaches service life more than 5 years.And timbering material adopts dragging and squeezing glass fiber reinforced plastics, by the polymer of glass fibre and macromolecule resin, and light weight, intensity is big, and good moldability has certain bending.Whole specification is that the upper part is 150cm * 150cm * 65cm, and end portion is 150cm * 150cm * 50cm.The end portion height is 50cm, and around the four sides net, pore size is 1.0mm, and promptly the mesh material is 18 orders.Wherein She Ji foundation is as follows: the first, and (3 instar larvae polypide mean breadths are 1.5 ~ 2.0mm to stop 3 ages or minority 2 instar larvaes to climb out of or jump out collecting net; 3 age the mature larva layup be 10 ~ 15cm, jump repeatedly).The second, the volume of design can be collected 2 ~ 3 layers of shedding.The screen distance of upper wire pledge material is 2.0mm, and promptly the mesh material is 10 orders.This design can stop adult to fly out, and is enough to allow the natural enemy parasitic wasp free in and out (the female male imago belly of citrus fruit fly mean breadth is 2.0 ~ 2.5mm, and the wing expanse average length is 10 ~ 12mm, and is as shown in table 1) simultaneously.
