Background technology:
Red fire ant (Solenopsis invicta Buren) is a kind of dangerous insect of invasion property, and invasion farmland, room, cause people and animals to injure, and bio-diversity is existed to serious threat.Red fire ant fertility is strong, and diffusion velocity is fast, and difficulty of prevention and cure is large.The Ministry of Agriculture of China has been decided to be red fire ant the inward plant quarantine pest of the People's Republic of China (PRC) and national plant quarantine pest, requires to be bottled up control.
For the serious harm of current red fire ant, China has carried out relevant ecology and the research work of Prevention Technique in a deep going way.Indoor research work need to be carried out colony's collection and separate.As a kind of social insect, red fire ant colony comprises each grade, and therefore field carries out when colony gathers comprising queen, worker ant and young ant (ovum, larva and pupa).Colony gathers and is mostly whole ant nest excavation to take back indoor at present; Indoor colony separates the main partition method of dripping that adopts, and the method exists shortcoming consuming time.Bibliographical information field queen collecting method; [Porter SD.Journal of Economic Entomology, 1993,86:1344 – 1347.].Lack at present the collecting method of young ant, become a technical obstacle such as colony's Quick Acquisition, young ant extraction and application.
Summary of the invention:
The object of this invention is to provide a kind of method of collection red fire ant children ant that rapidly and efficiently separates red fire ant children ant.
The method of collection red fire ant children ant of the present invention, it is characterized in that, near red fire ant ant nest, select open clean ground, or spread hard rubberized fabric near red fire ant ant nest, then coat lubricant in the lightshade cover inner side of the harvester of red fire ant children ant, again harvester is positioned on clean ground or hard rubberized fabric, base and ground or hard rubberized fabric close contact, or the gap that uses earth to seal base and ground or hard rubberized fabric, after red fire ant ant nest is dug out, be dispersed in around harvester, treat that red fire ant worker ant removes young ant to harvester through entrance, time needed amount, upset harvester rapidly, young ant on base and worker ant are poured in lightshade cover, complete the collection of red fire ant children ant,
The harvester of described red fire ant children ant comprises lighttight lightshade cover and base, and activity is fixedly connected with lightshade cover with base, at lightshade cover with base is movable has several entrances after fixing between lightshade cover and base.
There is the bayonet socket of several energy firm bankings in the lower edge of lightshade cover, in the lower edge of lightshade cover, also there are several breach, on base, there is the card corresponding with bayonet socket, thereby make lightshade cover in card card inlet, activity is fixedly connected with base, and the breach in the lower edge of lightshade cover just forms entrance.
Described lightshade cover is cylindrical, and diameter is 50~200mm, is highly 20~100mm, and described bayonet socket is 3~4, and described breach is 3~4, height 3~8mm.
In gatherer process, preferably utilize rubber gloves to carry out operation protection, after having gathered, just can take back laboratory, base is separated with lightshade cover, take out red fire ant children ant.
Described lubricant is preferably talcum powder, and talcum powder is easy to use, and with low cost.
The present invention compared to existing technology, has following beneficial effect:
1. the method for collection red fire ant children ant of the present invention; make full use of the behavioural characteristic of red fire ant worker ant protection larva; design lightshade cover; red fire ant worker ant can initiatively remove young ant to lightshade cover; without manually young ant being gathered; thereby improve collecting efficiency, also ensured the acquisition quality of young ant.
2. the method for collection red fire ant children ant of the present invention is utilized the behavioural characteristic of worker ant, can gather the major part children ant of the children of colony ant, makes the collection of colony relatively thorough.
3. the method for collection red fire ant children ant of the present invention, it is simple to operate, convenient, can not bite accident in sampling process, safer.
Therefore, the present invention has improved the collecting efficiency of red fire ant children ant, and the extraction and application of colony's collection, experimental study and larva to red fire ant etc. has important practical significance.
Embodiment:
Following examples are to further illustrate of the present invention, instead of limitation of the present invention.
Embodiment 1:
As shown in Figure 1, the harvester of the red fire ant children ant of the present embodiment, comprise lighttight lightshade cover 1 and base 2, described lightshade cover 1 is cylindrical, diameter is 100mm, be highly 50mm, there are 3 bayonet sockets 4 that are uniformly distributed energy firm banking in the lower edge of lightshade cover 1, in the lower edge of lightshade cover 1, also there are 3 breach 3, be highly 5mm, on base, have 3 cards 5 corresponding with bayonet socket 4, thereby card 5 snaps in and in bayonet socket 4, makes lightshade cover 12 activities are fixedly connected with base, the breach 3 in the lower edge of lightshade cover 1 just forms entrance.
The method of the collection red fire ant children ant of the present embodiment is: near red fire ant ant nest, select open clean ground, talcum powder is coated in lightshade cover 1 inner side at the harvester of red fire ant children ant, then harvester is positioned on clean ground, base and ground close contact, use earth to seal the gap on base and ground if any gap, after red fire ant ant nest is dug out, be dispersed in around harvester, treat that red fire ant worker ant removes young ant to harvester through entrance, initiatively removed to entering after harvester by worker ant until most of young ant, upset harvester rapidly, young ant on base and worker ant are poured in lightshade cover, complete the collection of red fire ant children ant, thereby reach the object that gathers red fire ant children ant, in gatherer process, can there is not red fire ant and bite accident, gather more thorough to the young ant in ant nest, collecting efficiency is high.
