What to do if there are bugs on the pumpkin vine, what is the matter with worms growing in the pumpk

This is caused by suffering from the damage of melon silk borer.

Melon silk borer is also known as melon wild borer and melon borer. It is mainly distributed in the provinces (regions) south of the Yangtze River, such as Jiangsu, Zhejiang, Hubei, Hunan, Sichuan, Guizhou, Yunnan, Guangxi, Guangdong, Jiangxi, Fujian and Taiwan.

The main hosts are cucurbitaceae, such as cucumbers, bitter gourds, loofahs, watermelons, zucchines, winter melons, melons, etc., and other hosts include tomatoes, eggplants, potatoes, sour pulp, nightshades, ivy, cotton, hibiscus, sycamores, etc. With larvae as the pest, the young larvae first gnaw on the mesophyll on the back of the leaf, and the damaged part is gray-white reticulated spots, and after the 3rd instar, the leaves or tender shoots are connected and rolled up, and they hide in it to feed, so that the leaves are perforated or missing, and only the leaf veins are left in serious cases, and even the host fruit and melon vine are bored.

Morphological characteristics. The melon silk borer belongs to the order Lepidoptera, the moth family. The adult (Figure 2) has a body length of about 11 mm and a wingspan of 25 mm.

Head and thorax black-brown, antennae grayish-brown, nearly wing-length long. The abdomen is white, but the segments and 8 are black-brown, and the abdomen ends in clusters of yellowish-brown hairs. The fore and hindwings are white and translucent, with a slight metallic purple light, and the anterior and outer margins of the forewings, as well as the outer margins of the hindwings, are broad black-brown bands.

The eggs are flattened and oval, pale yellow, with reticular stripes on the surface. Mature larvae (Figure 3) are 23-26 mm long. The dorsal plate of the head and prothorax is pale brown, the carcass is grass green, and the two subdorsal lines are thick and white.

Valve black. The pupae are about 14 mm long, dark brown, with a pointed and thin head, and wing buds extending to the 6th abdominal segment. The outer coat is cocooned.

Prevention and control methods. 1) After harvesting melons, clean up the melon fields in time to eliminate the pupae hidden in the dead vines and leaves to reduce the overwintering insect population.

2) In the early stage of larvae, pinch and kill the larvae according to the infested state, and remove the leaf curls in time to eliminate some larvae.

3) In the peak larval stage, 40% dimethoate emulsion, 50% dichlorvos emulsifiable concentrate, or 50% malathion 1000 times solution can be used; or 4% rotenol 600 times liquid; or 20% rapid killing butyr emulsifiable concentrate 3000 5000 times liquid spray, the effect is good.

Wrong upstairs!! It is a leaf mite hazard. If you have a layer of nets, you can't **, be careful not to infect other flowers. At the first hair, dimethoate can be sprayed with dimethoate emulsifiable concentrate.

Improper storage: Pumpkins have insects inside, which may be caused by insect infestation caused by poor ventilation. No sanitization:

The seeds are not sterilized before planting, and the seeds carry insect eggs. Unsprayed pesticides: When the pumpkin is in flowering, it is laid by insects, causing insects to grow when the fruit is ripe.

Maintenance method: Water the diluted liquor every 15 days in spring.

1. Improper storage

Pumpkin needs to be placed in a cool, ventilated environment for storage after picking, poor ventilation, it is easy to cause insect pests, pumpkin eggs hatch, worms will grow, pumpkin can be put into the refrigerator, low temperature storage, effectively avoid insect pests.

2. No disinfection

Before planting, pumpkin seeds need to be disinfected and sterilized to avoid insect pests, most of the pests will lay eggs in the soil, pumpkins grow in this soil, it is easy to grow insects, so it is necessary to expose the soil to the sun, and then spray carbendazim or plant ash for disinfection and sterilization.

3. No pesticides are sprayed

Some insects will lay their eggs on pumpkin flowers, without timely spraying of pesticides, pumpkin flowers will wrap the eggs in the fruiting period, and when the fruit is ripe, the eggs will hatch in it, resulting in worms growing in the pumpkin.

4. Maintenance method

Before planting, the seeds and soil must be fully disinfected and sterilized to prevent insect pests, and pesticides are usually sprayed regularly, and in spring, the diluted liquor is watered every 15 days, and it is used 4 times in a row, which can effectively control scale insects.

You can't eat it, it's a melon fruit fly.

The adult ovipositor tube pierces into the epidermis of the young melon to lay eggs, the larvae hatch and then eat in the melon, the victim of the melon first turns yellow, and then the whole melon rots and smells, resulting in a large number of falling melons, even if it is not rotten, the stinging wound is condensed with flow gum, deformed and sagging, the peel is hard, the melon taste is bitter and astringent, which seriously affects the quality and yield of the melon.

Clean the countryside Strengthen inspections, timely removal in the field and collection of rotten melons on the ground for centralized treatment (spraying or deep burial), which can help reduce the source of insects and reduce the harm. 2. Bagging melon protection In areas where serious damage often occurs or precious melon and fruit varieties, the method of bagging melon protection can be used (when the melon and fruit just bloom and the petals shrink) to prevent the adult from laying eggs.

Pumpkin seeds are the seeds of pumpkin, an annual creeping vine of the Cucurbitaceae family. It is mainly produced in Zhejiang, Jiangsu, Hebei, Shandong, Shanxi, Sichuan and other places. In summer and autumn, when the fruits are ripe, they are harvested, and the seeds are taken and dried. The main use of grinding powder, with fresh is good. It is used for tapeworm syndrome.

Raw pumpkin seeds have a good effect on killing parasites in the human body (such as pinworms, hookworms, etc.). It also has a good killing effect on schistosomiasis and is the preferred therapeutic product for schistosomiasis. American studies have found that eating about 50 grams of raw pumpkin seeds every day can be more effective in preventing and treating prostate diseases.

No. In fact, the worms in the pumpkin are harmed by a kind of insect called the melon fruit fly, which is generally pierced into the pumpkin by the adult worm to lay eggs and hatch and directly eat the internal tissues of the pumpkin. There is also a reason that the adult worm lays eggs in the flower, and the flower develops and bears fruit, which surrounds the eggs and finally hatches.

In warm regions, multiple generations can occur in a year, and insects generally overwinter in weeds. Summer is the peak season, hide in the shade under the high temperature, and come out of the hazard when it is cooler.

Adults lay eggs into the pumpkin fruit, and after the fruit hatches warmly, they begin to eat the young melon tissue, and the generally damaged parts appear yellowing and necrosis, and the pumpkin rots, and there will also be symptoms of stiffness, gelatinization and deformity at the oviposition, and finally the phenomenon of internal decay and external stiff shell.

1. Qingyuan. When the damaged fruit occurs, it is necessary to remove it in time, take it out of the field to bury it or poison the insects, remove the nearby weeds in time, and dry and burn all the diseased residues after the harvest is completed. It can be bagged at the beginning of the fruit to prevent the adult worms from laying eggs.

2. Site selection. Do not plant near the same melon vegetable planting field, and do not continue cropping with the same kind, you can rotate or intercrop with vegetables that are not harmed to reduce the source of insects.

3. Booby-trap. Adults have a certain tropism to sweet substances, and can be mixed with sweet and sour liquid and pesticide trichlorfon to attract adults to eat and poison the adults. It can also be used to dispense drugs with sexual attractants and trap them at fixed points in the field, and the effect is very good.

4. Spraying. Spraying pesticides at the peak of adult occurrence at noon when the adults are dormant can effectively kill the adults. Generally, 40% Lesben emulsifiable concentrate 1000 times liquid spray or enemy kill 2000 3000 times enemy kill and other insecticides with water spray. Some contact pesticides can also be used, which are more effective.

In the countryside, the pumpkins with pimples are generally picked and thrown directly, because there are already worms and lesions on the inside, and some of them are even rotten inside! So it's best not to eat it.

You guess... In fact, there are worms in it, which means that this pumpkin is not poisonous, depending on your preference!!

In our rural areas, we have lost everything, no one eats, and we are prone to diseases. It is recommended not to eat.

Pumpkin is a plant of the genus Pumpkin in the Cucurbitaceae family. The term "pumpkin" can be used to refer to the Chinese pumpkin in the genus Pumpkin, or it can refer to other cultivated species of the genus Pumpkin, including bamboo shoots (also known as Indian pumpkin) and zucchini (also known as American pumpkin).

Pumpkins are cultivated all over China. The tender fruit is sweet and delicious, and it is one of the melon vegetables in summer and autumn. Old melons can be used as feed or miscellaneous grains, so there are many places where they are also called rice melons.

In the West, pumpkins are often used to make pumpkin pies, or pumpkin cookies. Pumpkin seeds can be used as a snack. Pumpkin contains a lot of carbohydrates, fiber, sugar, etc., which will grow insects during the planting process; It is also possible that when you store the noodles at home, you don't eat them in time and give birth to worms.

The beneficial components of pumpkin to the human body are: polysaccharides, amino acids, active protein carotenoids and a variety of trace elements.

1.Pumpkin is an excellent B-carotene**, an antioxidant that helps keep people thinking sharply, and pumpkin seeds are rich in the mineral zinc, which is also important for brain function.

2.Polysaccharides: Pumpkin polysaccharides are non-specific immune enhancers, which can improve the body's immune function, promote the production of cytokines, and play a multi-faceted regulatory role in the immune system through the activation of complement and other pathways.

3.Carotenoids: The carotenoids abundant in pumpkin can be converted into vitamin A with important physiological functions in the body, which has important physiological functions for the growth and differentiation of epithelial tissue, maintaining normal vision, and promoting bone development.

4.Mineral elements: pumpkin is high in calcium, high in potassium and low in sodium, especially suitable for middle-aged and elderly people and patients with high blood pressure, which is conducive to the prevention of osteoporosis and hypertension. In addition, it contains phosphorus, magnesium, iron, copper, manganese, chromium, boron and other elements.

5.Amino acids and active proteins: Pumpkin contains a variety of amino acids required by the human body, among which lysine, leucine, isoleucine, phenylalanine, threonine and other contents are high.

In addition, the ascorbate oxidase genotype in pumpkin was the same as that of tobacco, but the activity was significantly higher than that of tobacco, indicating that the content of immunoactive proteins in pumpkin was higher.

Those are hatched from the eggs of flies and other insects, long before the melons and fruits are still flowers, insects lay their eggs on the flowers, and slowly the flowers become fruits and then wrap the eggs inside, and when the fruits are ripe, the eggs begin to hatch. It's like the one you can see, it looks good on the outside, but there are a lot of white bugs on the inside! It's a way for insects to reproduce!

To prevent it, you need to eliminate pests during flowering!

Answer 1, before the pumpkin blooms, the insect lays its eggs on the flower, and slowly wraps the eggs in the flower after the flower becomes a fruit, and the eggs begin to hatch when the fruit is ripe, so there are insects in the pumpkin.

Second, kill pumpkin bugs:

1. Mix liquor with water in a ratio of 1:2. When treating insects, water the surface layer of the potting soil thoroughly. Scale insects begin to move at room temperature 7 in spring. It can be poured once in April, and then every half a month or so, and it is effective for 4 consecutive times.

2. Use 50 ml of vinegar (rice vinegar), soak the small cotton ball in vinegar, and gently rub the wet cotton ball on the stems and leaves of the damaged flowers and trees, and then wipe off the scale insects to kill. This method is convenient and safe, which can not only achieve the purpose of insect control, but also make the damaged leaves green and shiny again.

3. Gently and repeatedly wipe the diseased plant with alcohol to get rid of the scale insects, and it can be removed very cleanly and thoroughly. If you wipe the orchid leaves with alcohol, not only can you get rid of the scale insects, but also the larvae that are not clear to the naked eye, and they are completely killed, and the second year is rarely found to have scale insects as a pest, this method is simple, safe, and the effect is good.

4. Use diesel, laundry detergent and water to adjust the mother liquor in the ratio of :6, at this time the mother liquor contains 60%, which is milk-like, dilute the oil content of 30% with water, and carefully spray the scale insects on Milan, kumquat and cycad. After one week, most of the scale insects changed from fresh orange to shriveled state, indicating that this method has a good control effect on scale insects.

Because you don't eat it! That's why bugs are born
