Background technique
Tick worm (Tick) is a kind of for the purpose of sucking blood, the temporary vermin for colonizing in humans and animals body surface, packet
Include hard tick and soft ticks two major classes.Hard tick is mainly distributed on the openings such as forest, grassland, bushes and half-desert;Soft ticks night
Activity is inhabited in sheltered situation such as the gap of shed, Bird's Nest and people beast dwelling more.Tick worm wide variety, the whole world has found tick
About more than 800 kinds of worm, wherein there are about 100 kinds in China.The tick worm history of life is complicated, and epidemiology status is important, can propagate a variety of people
The beast property suffered from disease such as tick-borne encephalitis, Lyme disease, spirochaetosis, Q heat, rickettsiosis and brucellosis etc. altogether, carries out tick
Worm pathogenesis can not be ignored.Currently, tick worm can not carry out laboratory culture, and without the effective acquisition equipment in field, mainly
It is obtained in such a way that artificial hand is grabbed.It is time-consuming and laborious that field labor arrests tick worm, by human factor and environmental factor such as weather shadow
It rings greatly, and expected ideal effect is often not achieved, often because obtaining fall short tick source or cannot get sufficient amount of tick worm, cause
It carry out research project can not, or progress has some setbacks, is delayed or even stranded.
Tick worm host type is more, mainly includes mammality, birds, reptiles and amphibian animal etc., larva, nymph and at
Worm can suck blood, and generally colonize in skin and be not easy by the position of excitement.Tick worm oxyosmia, possesses olfactory organ Haller's organ
(Haller ' s organ), has carbon dioxide characteristic, can perceive when with host at a distance of 15m, be changed by passively waiting
Active attack, once contact host i.e. climb and on.Such as forest ixodes persulcatus (Ixodes persulcatus) adult is sought
When host, it is gathered in grass point or the bush branch and leaf top on hill path both sides more, attached host is climbed when host passes through and contacts;
Desert Hyalomma asiaticum (Hyalomma asiaticum kozlovi) actively seeks host mostly in land operations.Tick worm activity
Range is little, generally tens of rice.

Specific embodiment
As shown in figures 1 to 6, the invention discloses a kind of fields to trap tick worm device, is a kind of for field capture tick worm
Type semienclosed container.
The field includes the open air or hole that the nobody such as forest, grassland, marsh, half-desert or few people live
The non-outdoor area such as cave, valley, irrigation canals and ditches.
The tick worm is with sucking blood and the carbon dioxide characteristic that becomes, to humans and animals health, there are the Arachnoideas of security risk
Vermin.
The container is steel container made of iron.
The container includes handle 1, fixinig plate 2, rain cover umbrella 3, gas container 4, stator blade 5, hanging ladder frame 6, pedestal 7 and dry ice
Store ware 8.
Hanging ladder 61 is height among cross section, both sides are low and have the prismatic pavement for sliding lines.
The pedestal 7 is by ridge 74 and the hollow round table that forms of pavement 73 with non-slip texture 75.
The dry ice storage ware 8 is the hollow hemisphere of opening upwards.
The access hole 9 be it is rectangular, it is quantity 4,6 or 8, identical as hanging ladder 6, the ridge of pedestal 7 and pavement number.
