Embodiment
Below in conjunction with drawings and Examples, to above-mentioned being described in more detail with other technical characteristic and advantage of the utility model.
In an embodiment, as shown in Figure 1, a kind of this device of device for laboratory live body amount reproduction entomopathogenic nematode of the utility model, this device comprises top cover 1, top cover 1 is arranged with at least one host and coils 2, host described in each is coiled lower end in 2 and is provided with one deck screen cloth, best mode arranges 3 hosts to coil 2, 3 hosts coil 2 for arrange up and down and two adjacent hosts are coiled 22 and are threaded connection, nethermost host is coiled 2 and is arranged with gathering unit, gathering unit both can be the funnel 3 of back taper also can be Buchner funnel 5, gathering unit is arranged with bracing frame 4.Top cover 1 upper end is provided with water injection hole 102 or air vent 101, wherein can arrange water injection hole 102 and air vent 101 simultaneously, also only can arrange one of them; Wherein top cover 1 lower end and host are coiled 2 upper ends and are threaded connection, and the lower end that funnel 3 upper end and host coil 2 is also threaded connection.
Above-mentioned threaded connection place is provided with the Rubber washer in order to sealing.
As shown in Figure 2, host is coiled 2 and is comprised host's disc main body 201, and host's disc main body 201 is the cylindrical of hollow, and the lower end in host's disc main body 201 is provided with one deck screen cloth, and wherein the aperture of screen cloth is 1-3mm.
As shown in Figure 3, bracing frame 4 comprises base 401, and all sides homogeneous vertical of base 401 is provided with three support columns 402, supports and comprises vertical section and arc section, and arc section supports funnel 3 or Buchner funnel 5.
As shown in Figure 1, gathering unit is the funnel 3 of back taper, and the lower end of funnel 3 connects a rubber tube 302, rubber tube 302 is provided with a clip 301.
As shown in Figure 4, receiving system is Buchner funnel 5, and Buchner funnel 5 lower end is also provided with a water storage bottle.
When using this device to cultivate propagating insects pathogenic nematode, as shown in Fig. 1 or 4, the worm's ovum of entomopathogenic nematode being evenly placed into together with the medium needed for it host coils on the screen cloth of 2, cultivate under being put into suitable temperature, treat that pathogenic nematode grows to certain length of time, from water injection hole 102 or open top cover 1, inject a certain amount of water, pathogenic nematode can enter gathering unit with current.As shown in Figure 1, gathering unit is the funnel 3 of back taper, and after the current of mixing pathogenic nematode enter the funnel 3 of back taper, leave standstill after 12h, due to the gravity of nematode self, can be deposited in gradually bottom rubber tube 302, when unclamping clip 301, nematode suspension can flow out; As shown in Figure 4, gathering unit is Buchner funnel 5, in Buchner funnel 5, place filter paper, after the current being mixed with pathogenic nematode enter Buchner funnel 5, owing to there being filter paper, after extraneous exhaust, nematode can be stayed on filter paper fast, and current enter water storage bottle 6, and the method is applicable to a large amount of nematode and collects.
