What kind of bug is in oily lettuce? What are the dangers to people?

This is an aphid and is not harmful to humans. Mainly harmful to crops. When the amount of 100 aphids in the field reaches 500 and the benefit-harm ratio is greater than 1 500, 50 ml of 25% aphid mite emulsifiable concentrate per mu, or 1500 2000 times of imidacloprid series products, and 60-70 grams of 10% aphid lice; 20% imidacloprid 2500 times; 25% anti-aphid 3000 times liquid spray control.

The wheat area where wheat aphid is resistant to imidacloprid and acetamiprid should not be used alone, and can be reasonably mixed and sprayed with low-toxicity organophosphorus pesticides.

Earthworms!

蚯蚓 [qiū yǐn].

Invertebrate.

Earthworms are one of the annelids, with more than 3,000 species of earthworms in the world and more than 200 species in China [2]. There are ringworms, Aisheng worms, heterolip worms, dura worms and other varieties widely distributed throughout the country.

Earthworms are rich in nutrition, rapid reproduction, miscellaneous diets, and high yield in artificial breeding. Good economic benefits. Earthworms can be used as a valuable medicine** for many diseases, and can also be used as high-protein food and feed.

Earthworms dig holes to loosen the soil, decompose organic matter, create good conditions for the growth and reproduction of soil microorganisms, and play a special role in soil improvement, elimination of pollution, protection of the ecological environment, material cycle, biodiversity, etc. [2]

Earthworms contribute to the material circulation and energy transfer of soil processes through activities such as feeding, digestion, excretion (vermicompost droppings), secretion (mucus) and burrowing, and are one of several soil invertebrate groups (mainly earthworms, mites and ants) that have an important impact on the processes that determine soil fertility, and are known as "ecosystem engineers".

Does anyone know what kind of bug this is?

There is no danger to people. This is an aphid, when the number of 100 aphids in the field reaches 500 and the benefit-harm ratio is greater than 1 500, 50 ml of 25% aphid mite clear emulsifiable concentrate per mu, or 1500 2000 times of imidacloprid series products, and 60-70 grams of 10% aphid lice; 20% imidacloprid 2500 times; 25% anti-aphid 3000 times liquid spray control.

Use 3 4 grams of washing powder, add 100 grams of water, stir into a solution, spray 2 3 times in a row, the control effect reaches 100% or add 600 800 times of water with "wind oil essence", and carefully spray the pests with a sprayer to make the insect body stained with the potion.

<> because of the bitter taste of lettuce, it is not easy to produce insects, but it is not completely insect-free. The common insect pests of oilseed wheat cabbage are aphids, which are adults and nymphs that live on the back of the leaves and young stems, and suck the sap for a living, which will cause the young stems and flower stalks to be damaged and bent, and the plants will be dwarf and weakened, and in severe cases, they can cause wilting and death. The control of aphids needs to remove weeds in and around the field when they are old, protect the natural enemies of aphids, such as plants, rolling lacewings, etc., and can also spray 10% insect mites 3000 times.

Summary. Habits:

Slug overwinters in adult or larvae under wet soil at the roots of crops. From May to July, a large number of activities in the fields are harmed, and in summer, the temperature rises, and the activities weaken, and in autumn, when the climate is cooler, the activities are harmful. Wild slugs are afraid of light, and die in 2-3 hours under strong light, so they are active at night, starting from the evening, reaching a peak at 10-11 o'clock in the evening, and diving into the soil or hiding places before the early morning.

There are black bugs in the lettuce, which will become longer and are not afraid of water, ask for their names, hazards, etc.

Oilseed lettuce is a common green vegetable, and has the effect of drying and moisturizing the lungs, lowering cholesterol, etc., and has become the first choice for many farmers to plant. For the above question, let's take a look at it together.

1. Aphids. The effective control method is to remove weeds in and around the field in time to protect the natural enemies of aphids, such as ladybugs, aphid flies, spiders, lacewings, etc. Aphids can also be used to trap and kill with phototaxis characteristics.

The use of natural enemies and phototropism booby-traps is both effective and environmentally friendly, which is in line with the development concept of green agriculture. When the insect pest first appears, it can be sprayed with 1000 times of 50% anti-aphid wettable powder, or 3000 times of 10% insect mite, or 10% more than 1000 times of Noble emulsion, sprayed once every 7-8 days, and used 2-3 times, it is recommended to use several liquids alternately to avoid pests from developing resistance and affecting the insecticidal effect.

2. Thrips. Thrips mainly harm the leaves and young parts of oilseed lettuce, it has no obvious dormancy period, and can be harmful all year round. It can be prevented with pesticides, and the prevention and control agents can be added to the watering to do a good job of daily prevention, and the concentration of pesticides can be increased when it is harmful.

3. Downy mildew. The prevention and control of downy mildew should follow the principle of agricultural prevention and control, supplemented by drug control. It is necessary to water small, and it is strictly forbidden to water violently with large water.

Increase the application of organic base fertilizer, balanced fertilization, and do not apply partially, less, and excessively. After the onset of the disease, it can be sprayed with 500 times of 75% chlorothalonil wettable powder, or 800 times of 69% enoylmanganese-zinc wettable powder, sprayed once every 7-8 days, sprayed 2-3 times in a row, which can have a better control effect.

The planting of rape is relatively simple, and it is best to choose varieties with strong disease resistance to planting rape.
