Cap type forest tick collection device

technical field

The invention relates to a cap-type forest tick collection device, which belongs to the technical field of zoology.

Background technique

Ticks are commonly known as grass crawlers and thin cattle stings. They belong to the subfamily of Arthropoda Arachnida and are divided into two groups: hard ticks and soft ticks. Adults have a relatively strong shell on the back of the body. , collectively referred to as hard ticks, which belong to the family Ixodidae; those without scutum, collectively referred to as soft ticks, which belong to the family Soft ticks. There are more than 800 species of ticks that have been found in the world, and about 110 species have been recorded in my country. Ticks are temporary parasites on the surface of many vertebrates. They lie dormant on grasses and plants in shallow mountains and hills, or lodge in the fur of livestock and other animals. They are the vectors and storage hosts of some zoonotic diseases. The worm body is oval. When not sucking blood, the back and abdomen are flat, and the back is slightly raised. The adult body is 2-10 mm long, the size is the size of shriveled mung beans, and some are as thin as rice grains; It is as large as a fingernail, about 30 mm. The epidermis is made of leather, and the back may have a shell-like scutellum. The insect body is divided into two parts: the jaw body and the body. Jaw body, also known as false head, is located at the front of the body and consists of jaw base, chelicerae, suboral plate and pedicles. The body is pouch-shaped, mostly brown, symmetrical on both sides. The development process is divided into four stages: egg, larva, nymph and adult. Adults mate and land after sucking blood, crawl on grass roots, tree roots, livestock houses, etc., and lay eggs in surface crevices. After laying eggs, female ticks dry out and die, and male ticks can mate several times in their lifetime. Eggs are spherical or oval, about 0.5-1 mm in size, light yellow to brown in color, and often piled up into clusters. Eggs can hatch into larvae in 2-4 weeks under suitable conditions. The larvae look like nymphs, but are small, with 3 pairs of legs. The larvae molt into nymphs after 1-4 weeks. Nymphs have 4 pairs of legs and no genital pores. The nymphs suck blood on the host, and then molt into adults after 1-4 weeks after landing. The lifespan of hard ticks ranges from one month to several decades; the adults of soft ticks can generally live for 5 or 6 years to dozens of years due to multiple blood-sucking and multiple laying eggs. Tick larvae, nymphs, and both male and female adults suck blood. Ixodes mostly attack the host during the day, and the blood-sucking time is longer, usually several days. Soft ticks mostly attack the host at night, and the blood-sucking time is relatively short, generally ranging from a few minutes to an hour. The amount of blood sucked by ticks is very large, and they can expand several times to dozens of times after being full of blood at each developmental stage, and the female Ixodes can even reach more than 100 times. Ticks often have a certain degree of selectivity in the host's parasitic site, generally in the thinner skin, not easy to be scratched, such as Ixodes pandox often parasitizes on the neck, behind the ears, armpits, inner thighs, etc. of animals or humans. genitals and groin etc. Ticks have a keen sense of smell and are sensitive to animal sweat and carbon dioxide. When they are 15 meters away from the host, they can sense it. From passive waiting to active waiting, once they touch the host, they will climb up. In the forest, it often climbs to high branches. Once people or animals approach, it can sense it. When people or animals walk into its falling range, it will fall quickly with the help of gravity, and then crawl until the skin is thin and not easy to be scratched. blood sucking. As of June 2011, there were more than 280 cases of tick disease reported in China, and more than 10 people died. It is also a common disease abroad. For example, spirochetes or viruses are transmitted through blood sucking, causing infected people to suffer from Lyme disease and forest encephalitis. cause great harm to people. Because ticks have caused great harm to people for a long time, countries all over the world are actively studying how to prevent and control them. This requires effective methods to collect ticks and study them in detail as specimens. In order to collect ticks, many scholars have designed many collection methods according to the characteristics of ticks themselves. At present, the most commonly used method is pulling a white cloth and walking, that is, the collector pulls a piece of white cloth and walks in the forest. collected afterwards. But this method requires people to pull with both hands and walk on the uneven forest surface. On the one hand, most of the ticks will fall on people, which brings danger to the collectors. On the other hand, it is easy to stain the white cloth. It is beneficial to the sorting of ticks, and the efficiency is low. Moreover, because the traction has to overcome the friction force, it is a very labor-intensive thing for the collector. Therefore, how to develop a method that can prevent ticks from falling on people, avoid the contact between the collection device and the ground, and reduce the energy consumption of the collectors has become a major problem that needs to be solved urgently. Therefore, using the structure that collects ticks into a head cap Wear it on the collector's head, let the collector's carbon dioxide and sweat smell diffuse from the worm cover cavity, and then lure the ticks to fall but not fall on the collector, and use the worm cover to collect ticks to achieve efficient collection It is necessary to invent a cap type forest tick collection device for the purpose of reducing the possible harm of ticks to people.
