How do I find a watermelon bug? How do you catch watermelon worms in large quantities?

Watermelon bugs. Scientific name rat woman.

They all need to live in humid, warm and sheltered places, and they are nocturnal and have negative phototaxis and fake death. It is not highly adapted to life on land like insects and spiders, it is distributed in most parts of our country, and in the field, it mainly harms cucumbers, tomatoes, rape, etc., so you can find it under damp bricks or stones, or in the soil of the above-mentioned plants, I hope you can find it! If you don't understand, please ask, my biology is very good o( o

In some mounds, in flowers, in ponds, on the banks of small rivers.

You can use watermelon insect trap, take 50 grams of water and 1000 grams of diluted cloth strips for 10 minutes.

In the wild, choose a good place to place the potion cloth strip before dark, and the watermelon insect often likes to haunt the places in front of the house, behind the house, garbage piles, stone piles, etc.

The principle of trapping watermelon insects is the unique smell of traps, and watermelon insects like it very much. The powder can diffuse the volatile odor and attract watermelon insects to track it.

Watermelon insects mainly harm melon seedlings and vegetable sprouts, young roots and strawberries and other berries in the field. He likes rape, mustard greens, bok choy, tomatoes, cucumbers, pumpkins, gourds, soybeans, cowpeas, amaranth, water spinach and other leaves and edible fungi.

It will cause lack of seedlings and broken ridges, and eat berries into holes when harming strawberries; The green part of melon seedlings often does not grow vines after being damaged. Significant impact on production.

Morphological characteristics. Adult body 10 to 14 mm long, body width 5 to 6 5 mm, oblong-elliptic, 13 segments, grayish-brown, head with 1 pair of linear antennae; There are 8 segments on the thorax, 1 pair of feet on each segment, 7 pairs of gastropods on the abdomen, and two flaky protrusions at the end of the caudal segment. The female adult body is dark brown on the back, with faintly yellow-brown cloud-like lines, and the posterior margin of each segment has a white edge, and the male is blue-black. The hatchling larvae are white, translucent, about 1 3 to 1 5 mm long, 0 5 to mm wide, and then gradually darken, similar in morphology to adults, differing only in size and body color.

Habits. Living on humid land The insect viviparously reproduces, leaves the mother body can move freely to feed, after feeding, the body wall color becomes darker, the body increases, every time needs to burrow into the soil to molt, each female can reproduce 110 heads, the larvae hatch after more with the female adult swarm in the to, after about 1 to 2 5 months to begin to live independently, after 1 year of maturity, mostly occur in the dark and damp corner of the wall or stone, under the clods, the night is harmful, to 21 to 22 o'clock in the evening, 7 to 8 o'clock in the morning is the most active, cloudy days also come out to move, Seedlings and ground fruits are susceptible, have tropism to circle fertilizer and rotting weeds, have negative phototaxis and feigned death, and immediately shrink into a "watermelon" shape after being frightened.

In addition, experiments have shown that watermelon insects have an interesting walking style when encountering obstacles, bypassing obstacles in the order of left, right, left, right, left, right, left, right

In addition, there are many kinds of watermelon insects in China, which are widely distributed indoors and in humid places, and also harm rape in the field.

Prevention and control methods. 1) Prevention and control should be strengthened in vegetable fields and ponds and ditches near the village. There are no weeds left in the field, and rotting grasses are collected between the ridges and ridges for attractance.

2) Avoid applying organic fertilizer that is not fully decomposed in vegetable fields.

Watermelon insect is not an insect, the scientific name of watermelon insect is rat woman, also known as tide insect, ball worm, ground lice, etc., which is the common name of the rat woman of the tide insect family. There are more than 150 species in the world, most of them are widely distributed worldwide species, and most of the bodies are long ovate.

Watermelon insect is a pest, will produce harm in agricultural production, will cause lack of seedlings and broken ridges to melon seedlings and cruciferous vegetable sprouts, young roots and strawberries and other berries and other crops, harm strawberries when eating berries into holes, melon seedlings often do not grow vines after being damaged, which has a certain impact on production, and is one of the common pests in the field.

Habits

Watermelon insects generally prefer very humid environments, so they can be easily found in some humid places, such as under rocks, under leaves, and under sewers. Of course, they also have temperature requirements, and generally a temperature of 25 degrees is best for them. They all live outdoors, but many friends will also find some watermelon insects at home in summer.

If you live in a building, these watermelon worms are likely to climb up from the sewer, or they may be carried outdoors.

OK. Watermelon bugs often hide in the soil. Rest.

Choose the soil to be black, and sprinkle it regularly, not too much, to keep the soil moist. Watermelon insects love to eat vegetables, fruits and other watery foods, but also pay attention to the regular change of soil, as for what to raise, as long as it is a bottle can be raised, if it is a plastic or glass bottle, do not add too much soil, such a bottle is very smooth, watermelon insects can not climb up, naturally can not escape.

1. Watermelon insects are usually placed in a pot to provide it with a dark and warm environment. Be careful not to have too much density, otherwise the eggs are easily disturbed, which can lead to premature egg laying. 2. The humidity should also be controlled well during breeding, it is not resistant to dry environment and avoids death.

3. In addition to feeding, you should also feed putrefined food or rotten leaves, and supplement an appropriate amount of feed with the growth. 4. In addition, it is necessary to prevent and treat diseases and natural enemies.

Watermelon insects live in damp, humus-rich places, such as under damp rocks, under decaying wood, in tree cavities, in damp grass and moss, under water tanks in the garden, under flower pots, and even in damp places indoors. Omnivorous, eating dead leaves, dead grass, green plants, fungus spores, etc.

The watermelon insect, also known as the rat woman, has an oval or oblong body, is flattened, has a slightly raised back, and its 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.

The anterior two abdominal segments are narrower but not significantly narrower than the thorax, and the segments tend to be narrower 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.

Watermelon insect is precisely the rat woman, the rat woman is also known as the rat negative, negative pan, rat girl, rat sticky, ground lice, etc., is the common name of the crustacea and other pods (isopoda) tide insect suborder (oniscoidea) tide insect family (oniscidae) rat woman (porcellio) animals, there are more than 150 species in the world, most of them are widely distributed worldwide species. 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 question you asked, the watermelon worm** is as follows:

Rats (wet insects) are commonly known as rice soup insects, tide insects, tide insects, tuanzi insects, ground lice, ground lice, shoe board insects, skin plate insects, etc., belonging to the invertebrate arthropod phylum mollusc class tide insects suborder tide insects of the family Rats. There are many types of rat women, and the common species are representative animals such as tide insects, rats**, ball rats**, etc. They are mostly ovate-shaped and are the only crustaceans that are fully adapted to life on land, from the seaside to the highlands around 5,000 meters above sea level.

It lives in humid, warm and sheltered places, and is nocturnal and has negative phototaxis. The shell of the rat woman has a thin layer of oil, which is not easy to be stuck by spider webs, etc., and is suitable for life on land.

Sprinkle with salt: In areas where watermelon insects are frequented, sprinkle salt and check once at intervals. Put sticky bug paper:

It is used to trap the adult watermelon insect invading the room, effectively preventing the adult watermelon insect from invading the indoor and causing harm, and reducing the risk of invading the indoors. Spraying drugs: Use drugs to spray the active areas found by watermelon insects, such as gaps in wall foundations, floors and other areas.

1. Sprinkle edible salt: In areas where watermelon insects are often infested, sprinkle edible salt, and check once at intervals.

2. Put sticky insect paper: It is used to catch the adult watermelon insect invading the room, effectively preventing the adult watermelon insect from invading the indoor and causing harm, and reducing the risk of invading the indoors.

3. Spraying drugs: The active areas found by watermelon insects are sprayed with drugs, such as the cracks in the wall foundation, the ground and other areas.

Prevention and control methods: 1. The vegetable fields and pond ditches near the village should be strengthened. There are no weeds left in the field, and rotten grass is collected between the ridges and ridges for booby-trapping.

2) Avoid applying organic fertilizer that is not fully decomposed in vegetable fields.

3. Combined with the prevention and control of underground pests and spraying. In the juvenile stage of rapeseed, when it was found that the insect quantity was large, it began to spray 1500 times of 25% kashi emulsifiable concentrate or 2000 times of 20% worm dead net wettable powder and 2500 times of 10% imidacloprid wettable powder.
