What are the characteristics of the Rat Woman s living environment, the Rat Woman s living environme

It is the common name of the Isopoda, Oniscoidea, Oniscidae, and Porcellio.

There are more than 150 species in the world, and most of them are widely distributed worldwide. They are mostly long ovate in shape and can be found from the seashore to the highlands at an altitude of about 5,000 meters. The common species in China include rat woman, smooth rat woman, etc.

The earliest record of the rat woman can be found in the insect part of the "Compendium of Materia Medica".

The rat woman is one of the crustaceans adapted to terrestrial life, usually living in moist, humus-rich places, such as under rocks in damp places, under decaying wood, in tree cavities, in damp grass and moss, under water tanks in courtyards, under flower pots, and even in damp indoor places. Omnivorous, eating dead leaves, dead grass, green plants, fungus spores, etc.

Curly ball rat woman mainly harms tomatoes, rape, etc. Symptoms, larvae damage the leaves, resulting in a lack of trees, the heavy ones can eat the mesophyll, only the leaf veins, petioles. Adults are 9-15 mm long, brownish-grayish-blue, with yellowish-white margins on each dorsal carapace.

It mostly occurs in coastal areas, and occurs in the second year of Dalian, with adults or larvae wintering underground, and a large number of them appear in March of the following year, which is at the stage of vegetable seedlings. Diurnal and nocturnal, with negative phototaxis.

By observing the process of searching for the rat woman: the number of rat women is the largest under the stones by the sink and under the wet flower pots where flowers are planted, while the number of rat women on the cement road and hay is very small Comparing the differences between the two environments, it can be found that the main difference conditions are: light and moisture, while the number of rat women is mostly concentrated in a dark and humid environment, while the number of rat women in a bright and dry environment is very small It can be inferred:

The suitable environmental conditions for the rat woman are: dark and damp

Therefore, b

Rat women prefer to grow in a dark, damp environment.

It generally inhabits rotten wood, rotten leaves, stones, etc., and sometimes appears in houses (thatched houses) and courtyards, and it is normal for rat women to live between 20 and 25 degrees Celsius.

The scientific name of the rat woman is the common curly beetle, commonly known as tide insects, watermelon insects, etc., belonging to the arthropod phylum Crustacea and other pod rats**. This group of animals is distributed throughout China.

The body is oval or oblong, flattened, slightly raised on the back, and the body can be curled into a spherical shape. Some species have a smooth back, while others have coarse grains. The head is small, inconspicuous, embedded in the anterior border of the 1st thoracic segment.

The cephalic segment has prominent lobes in the middle and on both sides. Broad chest, 7 free joints. The abdominal segments are 6 segments, the first two abdominal segments are narrower, but not significantly narrower than the chest, and each segment narrows posteriorly.

The flanks of each thoracic and abdominal segment are generally enlarged to form lateral lobes, the outer terminal angles of each thorax and abdomen on both sides protrude posteriorly and inferiorly, and the ends of the caudal segment protrude posteriorly and are triangular. The eyes are well developed and compound eyes. The first antennae are small, with short whiskers at the apex; The second antennae are long, with 5 stalk segments and 2 whip segments.

The labial base is arcuate, the large jaw has no tentacles, the cutting part is highly chitinized, generally has 2 toothed plates, there are membranous small lobes behind the tooth plates, and the molars are degenerated. The outer lobe of the first small jaw is a masticatory leaf, and the inner lobe is narrow and long, with 2 stiff hairs; The second jaw is divided into 2 lobes at the apex, with an outer margin angular process near the base. The base of the jaw limb is broad and lamellae.

Shape characteristics: The rat woman is round, and the body can curl up into a ball. Characteristics of life:

Survive under damp rocks as well as in shady places indoors. Types of rat women: smooth rat women, square rat women, rough rat women, buzzing rat women, etc.

Hazard control: Mixed with fenethrin and soil sprinkled on the ground, it can effectively control insect pests.

1. Shape characteristics

The rat woman is round or oblong, the body can curl up into a ball, the back is smooth, the head is small, the eyes are developed, the antennae are small, there are 7 pairs of slender thoracic limbs, and the abdomen has a pseudotrachea, which is a unique respiratory organ to adapt to the humid environment.

2. Characteristics of life

The rat woman is an omnivorous animal that usually lives under damp rocks, decaying wood, damp grass, and in cool and damp indoor areas.

3. Species of rat women

The smooth rat woman is native to the eastern hemisphere, the color is gray-brown, the male body is 10-15 mm long, the square rat woman body is oval, the body length is millimeters, the body surface has granular nodules, the rough rat woman can not roll into a spherical shape, the color is gray-black, the color of the humming rat woman is brown-brown or flesh-colored, with pale yellow patterns.

4. Hazard prevention and control

Rolling rat larvae will harm crops, scourge leaves, serious times will eat up plant leaves, only leaf veins and petioles remain, in March every year, a large number of vegetable seedling stage, at this time can be used with cypermethrin or 20% rapid killing and soil mixed sprinkled into the ground, can effectively control insect pests.

Rat women like to inhabit rotten wood, rotten leaves, stones, etc., and sometimes appear in houses and courtyards Rat women live normally between 20---25 degrees If the indoor and outdoor temperature is about 25 degrees, it can be found in the front and back of the house, under the stones, rubble, in the basin, and in the altar; When the temperature is lower than 25 degrees, you need to choose a warm flower cellar, next to the sewer in the courtyard for collection, and you can also collect it under the kitchen floor tiles in bungalow conditions When we collected in the school garden, we found that the number of rat women is small, and the individuals are smaller, mainly some small individuals can be collected under the flower pots, but the number is small, if the flower pots are placed on the cement floor, their number will be very small, and the amount of excessive water will be greatly reduced So through the collection experience, it can be seen that the rat women are suitable for living in a dark and humid living environment

So the answer is: dark and damp.

Rat Woman. Rat women prefer dark, damp environments, and generally inhabit under rotten trees, rotten leaves, stones, etc., and sometimes appear in houses (thatched houses) and courtyards. It is normal for rat women to live between 20---25 degrees.

If the indoor and outdoor temperature is about 25 degrees, it can be found in the front and back of the house, under the rubble, in the basin, and in the altar; If the temperature is below 25 degrees Celsius, you need to choose a warm flower cellar, next to the sewer in the courtyard, or under the kitchen floor tiles in bungalow conditions. When we collected in the school garden, we found that the number of rat women was smaller, and the individuals were smaller, with some small individuals being the mainstay. It can be collected under the bottom of pots, but the number is small, if the pot is placed on the concrete floor, the number will be very small, and the amount of excessive water will be greatly reduced.

For the convenience of collection, we found after some efforts that if the Taiwanese grass is shoveled up and covered on the lawn next to the wall (can be covered with two to three layers), do not water for a few days, and after the grass is dry, water a small amount of water for about three days, as long as it is relatively wet. If you start collecting in about a month, you can get a larger number of rat women. Moreover, the harvesting process is very convenient, as long as the turf is removed.

During the collection of rat women, it must be carefully protected, and after collection, the container should be filled with some wet soil and pay attention to ventilation. Wet soil is best rich in organic matter, the color is best black, at the same time you can put a few rotten leaves or some small roots of plants, you can also dig a pit in the ground in a dark corner when collecting, put in a plastic cup, the mouth of the cup is flush with the ground, put a little fruit in the cup, and a large number of rat women can be lured overnight.
