Description

Wild tick trapping device

Technical Field

The invention belongs to the technical field of fixed devices of traps, and particularly relates to a field tick trapping device.

Background

Ticks (Tick) are ectoparasites, including hard ticks and soft ticks, that temporarily colonize the body surface of humans and animals for purposes of blood aspiration. Hard ticks are mainly distributed in forests, grasslands, shrubs, semi-deserts and other open areas; soft ticks move at night and perch in hidden places such as animal holes, bird nests and gaps in human and animal dwellings. Ticks are diverse in variety, more than about 800 ticks have been found worldwide, of which there are about 100 species in our country. The tick has complex life history and important epidemiological status, can transmit various zoonotic diseases such as forest encephalitis, lyme disease, tick-borne fever, Q fever, rickettsia disease, brucellosis and the like, and can not be ignored in the research of tick pathogenesis. At present, ticks cannot be cultivated in a laboratory, and an effective wild capturing device is not available, and the ticks are mainly obtained through a manual grabbing mode. The field artificial capturing of ticks is time-consuming and laborious, is greatly influenced by human factors and environmental factors such as weather, often does not achieve the expected ideal effect, often causes research projects to be unable to develop or progress to be unsmooth, delayed or even stranded because a target tick source is not obtained or a sufficient number of ticks are not obtained.

The tick host is of a large variety, mainly comprising mammals, birds, reptiles, amphibians and the like, and larvae, nymphs and adults of the tick host can absorb blood and are generally parasitic on the parts of the skin which are not easy to scratch. Ticks are olfactory and sharp, possess an olfactory organ Hardwang (Haller's organ), possess carbon dioxide-chemotactic properties, are perceived when 15m from the host, are transformed from passive waiting to active attack, and climb upon contact with the host. For example, when the adult forest whole-furrow hard ticks (Ixodes persulcatus) seek the host, the host is climbed when the host passes by and contacts with the tips of grass or shrub branches and leaves on two sides of the mountain road; the Adenophora muricata (Hyalomma asiaticum kozlovi) mostly moves on the ground and actively searches for hosts. The tick activity range is not large, typically tens of meters.

Detailed Description

As shown in fig. 1-6, the present invention discloses a field tick trapping device, which is a semi-closed container for trapping ticks in the field.

The field comprises forests, grasslands, marshes, semi-deserts and the like, outdoor where no or few people live, or non-open areas such as caverns, canyons, ditches and the like.

The ticks are arachnids ectoparasites that have hematophagous and carbon dioxide-seeking properties and present a safety hazard to human and animal health.

The container is a steel container.

The container comprises a handle 1, a fixing piece 2, an umbrella 3, an air container 4, an air guide piece 5, a suspension ladder frame 6, a base 7 and a dry ice storage dish 8.

The hanging ladder 61 is a prismatic walk with a cross section with a high middle and low sides and sliding lines.

The base 7 is a hollow round platform formed by a ridge 74 with anti-skid lines 75 and a pavement 73.

The dry ice storage dish 8 is a hollow hemisphere with an upward opening.

The access holes 9 are square, and the number of the access holes is 4, 6 or 8, which are the same as the number of the hanging ladder 6, the back of the base 7 and the walkways.

The operation flow is as follows:

1. fixing, welding and installing the device;

1) Through the stationary blade, link to each other handle and umbrella, accessible nut screws or welded mode go on, the former portable, but time consuming and laborious when placer is more.

2) The umbrella is welded onto the air container and once welded, is used for a lifetime.

3) After the hanging ladder is arranged in the groove above the base, the air guide piece is sleeved outside the base.

4) The upper connector A (inner screw) of the air container is butted with the upper connector B (outer screw) of the base, and the air container is screwed.

5) And (3) butting and screwing the interface C (outer screw) below the base with the interface D (inner screw) on the dry ice storage dish to prevent the dry ice storage dish from being lost in the transportation process.

2. Selecting a tick field capturing point, and placing a device and dry ice;

1) The trapping device is transported to a field capture site according to research requirements and human intent.

2) And (5) screwing off the dry ice storage vessel, putting a small amount of dry ice, screwing and checking whether the device is airtight.

3) The device is placed on a soil slope, a dry branch, a fallen leaf pile or is suspended in a grass.

4) The staff member continues to place other devices or withdraw directly.

3. And (5) unloading the device and harvesting ticks.

1) The dry ice volatile gas is stored in the gas container, and the redundant gas escapes through the hanging ladder, the access hole and the anti-skid footpath.

2) The ticks around the placement point of the device seek carbon dioxide and fall into the hollow base reversely through the anti-skid footpath.

3) Unscrewing the A-B interface, taking out the suspension ladder, and harvesting ticks above the base.

4) According to research needs, for example, when ticks of specific hosts are caught, the lower part of the base can be designed into a flat bottom for accommodating small animals; toxic substances may also be added for killing ticks.

Ticks are ectoparasites which are temporarily parasitic on the surfaces of humans and animals for the purpose of sucking blood, and can spread various zoonotic diseases including forest encephalitis, lyme disease and the like, and have become an important study object for scientists. To date, ticks cannot be cultivated in the laboratory and are not available with field capturing devices, mainly obtained by manual grasping, which often results in failure to develop the desired study due to the inability to obtain a target tick source or a sufficient number of ticks. The invention provides a complex device for trapping ticks in the field, which utilizes the characteristic that ticks tend to be carbon dioxide, and traps the ticks in a semi-closed container through a walk and a suspension ladder. The device has ingenious design, is simple and convenient to operate, is easy to carry and place in the field, and is not influenced by human factors and environmental factors such as weather.
