Do insecticides work against the seven star ladybug, and what medicine works well with the seven sta

The specific effect of insecticides on the seven-star ladybug varies depending on the type and concentration of the insecticide.

Low-toxicity insecticides and biological insecticides may have some effect on the seven-star ladybug, but usually do not cause serious harm to it. For example, common low-toxicity insecticides on the market include pyrethroids, chlorantraniliprole, and imidacloprid, while biopesticides are insecticides based on natural products such as microorganisms, insects, and plants, including Bacillus thuringiensis, methylphenol ester, and zinc oxide.

However, chemical pesticides such as carbamate, methyl tobuzine and dichlorvos may cause greater harm to the seven-star ladybug. Caution should be exercised when using any insecticide and guidelines for safe use should be followed.

In addition, the seven-star ladybug does not like the taste of flower water, so you can consider using flower water to repel the seven-star ladybug. At the same time, the ladybug attaches to the plant to lay eggs, so if you want to get rid of the ladybug completely, you can consider removing the plant.

The most effective insecticides to kill ladybugs are bifenthrin, cyhalothrin, chlorpyrifos and other pyrethroid agents. Ladybugs don't like the smell of toilet water, so if you have a ladybug at home, you can spray some toilet water. Ladybugs attach themselves to plants to lay eggs, so if you want to get rid of them completely, you can consider removing the plants so that they will not be infested by them.

I use it at home, and it works. Spray on windows, doors, or places frequented by Sister Hua, and close doors and windows (when no one is around) for 15 minutes. Works great.

1. Kill the seven-star ladybug.

The most effective insecticide.

1. The most effective insecticides to kill seven-star ladybugs are bifenthrin and cyhalothrin.

Chlorpyrifos and other pyrethroid agents. In addition to this, orange peel.

If there are frequent ladybugs in the house, the orange peel that is usually eaten can be kept and dried, and after it is burned, the smoke can drive the seven-star ladybug away.

2. Seven-star ladybugs don't like flower water.

smell, so when a seven-star ladybug appears in the house, you can spray some toilet water, and when it smells the scent of flower water, it will fly away on its own. The seven-star ladybug is very fond of yellow, and you can take advantage of this by placing a yellow cloth outside the window, and the seven-star ladybug will be attracted out.

3. The seven-star ladybug will attach itself to the plant to lay eggs, so even if the seven-star ladybug is driven away, if it lays eggs on the plant, the seven-star ladybug will appear again after a period of time. If you want to get rid of the Ladybug completely, you can remove the plant so that there will be no more Ladybugs.

Second, the seven-star ladybug is a pest or a beneficial insect.

1. The seven-star ladybug is a beneficial insect. Ladybugs are both pests and beneficial insects, it has many species, mainly divided into carnivorous ladybugs and herbivorous ladybugs from the feeding habits, adult carnivorous ladybugs will prey on insects with tender flesh, and their favorite food is aphids.

For example, the seven-star ladybug. Most species of herbivorous ladybugs feed on plants in the Solanaceae, Cucurbitaceae, and Asteraceae families, such as the potato ladybug and the eggplant ladybug, which eat the leaves of eggplants and potatoes, which are pests.

2. Ladybug is the common name of the round protruding beetle of the Coleoptera ladybug family, their body color is bright, generally red, black or yellow spots, also known as fat and small, red lady.

Sister Hua, Golden Turtle, etc. Some ladybugs are commonly known as stinky turtles because of the foul smell of certain secretions, and the ladybug's life will go through four stages of full growth: egg, larva, pupa and adult.

3. The adult life span of the seven-star ladybug is relatively long, with an average of 77 days, and the adults and larvae will prey on aphids, leaf mites, whiteflies, and corn borers.

Aphids, bollworms.

and so on. The feeding amount of the seven-star ladybird is related to the temperature and prey density, and generally under the condition of high temperature, the activity ability and predation rate of the seven-star ladybug will increase.

Ladybugs can be killed with trichlorfon, notoginseng powder, ethyl spinoxida, azolfenamide, cyantranidin, endimidameth, avermectin and other drugs. If the ladybug is not numerous, you can take advantage of its phototaxis, install black lights around the garden, put pots under the lamps, and fill the pots with water or kerosene to trap them.

If it is not a seven-star ladybug, it is recommended that you use dichlorvos to kill them all, but before you hit dichlorvos, spray a new high-fat film, otherwise it will cause too much damage to crops, and pesticides are chemical drugs.

The seven-star ladybug can be killed with any pesticide, because he is very impatient, and he can be killed with ordinary dichlorvos or dimethoate.

Trichlorfon liquid, dichlorvos, and notoginseng powder can all kill ladybugs.

1.Control of adult insects (1) In the peak period of adult emergence, the adults are used to have phototaxis, and black lights are installed at the edge of the nursery, and a water basin is placed under the lamp, and some kerosene is dripped into the water for booby-trapping. Pesticides are used in combination under lighting to prevent aggravation of hazards in the vicinity of the lighting area.

2) Some of the overwintering adults are unearthed from mid-to-late April to early May, and can be booby-trapped with sweet and sour solution, and the formula ratio is: 6 parts of sugar, 3 parts of vinegar, 1 part of liquor, 10 parts of water, and 1 part of 50 trichlorfon. After mixing, take fresh young poplar leaves and soak them, sprinkle them evenly in the trail ditch between the nurseries, and retrieve them overnight.

3) Smear the residue of the eaten watermelon peel with the concentrated trichlorfon solution, place it in the trail ditch between the nurseries, place a piece every 7 meters, and change the melon skin every 3 to 4 days.

4) Tie fresh castor, poplar and other branches into handfuls, soak them in 90 times the liquid of 90 crystal trichlorfon, and insert them into the nursery at about 5:00 p.m., 5 handfuls per mu, and each handful is spaced 10 to 14 meters apart.

5) Some beetles are addicted to eating castor leaves, and will be paralyzed and poisoned after being full, and even die, so planting castor beans as booby traps around the nursery and between the intervals has a certain effect, but they often wake up after paralysis and poisoning, so they should be killed in time. Mash with kilograms of castor leaves, add 5 kg of water, soak for 2 hours and then filter, and spray with filtrate in the affected area can also kill beetle adults.

Ladybug can be killed with trichlorfon, Panax notoginseng powder, ethyl spinosadin, azolfenamide, cyantranidin, enyldimidamin, avermectin and other drugs. If you can take advantage of the phototaxis of ladybugs when the number of ladybugs is small, install black lights around the garden, put pots under the lamps, and fill the pots with water or kerosene to trap them, the effect is particularly good.

Ladybug control with trichlorfon special drug. In addition, Panax notoginseng powder, azolafeniliprole, ethyl spinosadactin, cyantraniliprole, difenethoxamin + avermectin, acetamiprid + avermectin and other agents also have certain effects.

Seven-star ladybugs, tortoise ladybugs, heterochromatic ladybugs, etc. are beneficial insects and do not need to be controlled. If it is a 28-star ladybug, it is a pest, and it needs to be sprayed to prevent it. Be sure to distinguish the species of ladybugs, so as not to kill the beneficial insects.

To control the 28-star ladybug, you can use pyrethroid agents such as bifenthrin or cyhalothrin plus chlorpyrifos spray.

The insecticide is able to kill the seven-star ladybug. It's a very thorough approach. However, generally speaking, if it is a ladybug with seven points on its back, it is not harmful to the human body, and the seven-star ladybug is a beneficial insect.

So if you don't want to create a ladybug tragedy, you can take other methods. And the seven-star ladybug does not have a long lifespan, and if there is no food, it will disappear on its own.

Seven-star ladybug. It can be used with drugs like dimethoate, which can be very good for insecticide.

Summary. What season is it good to spray ladybugs.

1. Ladybugs generally come out in summer, so it is better to spray in summer, and it is best to be close to noon when spraying, because the dew is too heavy in the morning and the humidity is too heavy at night (the spraying effect is better at 1-2 o'clock in the afternoon), if the pesticide will be washed to the ground by dew too early.

2. Windy weather is not suitable for spraying, because pesticides will flutter around with the air, and it is not easy to attach to the surface of crops, affecting absorption. Cloudy or rainy days are also not suitable because they will directly wash away the chemicals, which will not only prevent the crops from absorbing, but also cause river water pollution.

3. If the weather is particularly hot, do not spray, because the high temperature will accelerate the decomposition of the agent, increase the volatilization, and shorten the validity period of the pesticide, which is very disadvantageous.

What pesticides can be used to kill the seven-star ladybug.

In the past, we sold a medicine called diamond diamond, which was designed to kill the seven-star ladybug.

Ladybugs are very afraid of pesticides, so they can be killed by using Cresso. If it is on the branch of the plant, you can use a plastic bag to cover it, and then shake it and it will fall into the bag, and then seal it and kill it. If it's winter, it's easier to deal with, it's Xunshan doesn't eat or move, and you can kill it by catching it with your hands at this time.

There are also seven-star ladybugs that can be killed with trichlorfon, seven-to-ginseng powder, ethyl spinocidamycin, azolfenamide, bromide and cyantranidin, endimidamide, avermectin and other drugs. If it is an overwintering adult, you can use sweet and sour liquid to trap and kill, the formula ratio is 6 parts of sugar, 3 parts of vinegar, 1 part of liquor, 10 parts of water, 10 parts of water, 50 trichlorfon several rounds of 1 part, some ladybugs like to eat castor leaves, after full food will be paralyzed and poisoned, you can plant castor beans around the nursery as a booby-trap.

It eats the leaves on the carob leaves.

Ladybugs in what season is it good to spray 1, ladybugs generally come out in summer, the shirt is sold to spray in the summer is better, it is best to be close to noon when spraying, because the dew is too big in the morning, and the humidity is too heavy at night (the spraying effect is better at 1-2 o'clock in the afternoon), if the pesticide will be washed to the ground by dew too early. 2. The weather with strong winds or ridges is not suitable for spraying, because the pesticide will flutter around with the air, and it is not easy to attach to the surface of the crop and affect the absorption. Cloudy or rainy days are also not suitable because they will directly wash away the chemicals, which will not only prevent the crops from absorbing, but also cause river water pollution.

3. If the weather is particularly hot, do not spray, because the high temperature will accelerate the decomposition of the agent, increase the volatilization, and shorten the validity period of the pesticide, which is very disadvantageous.

So what kind of medication.

The ladybugs of carob are used to kill the enemy with high-efficiency and low-toxicity pesticides to prevent metallurgy. Spraying pesticides to reproduce, common agents are dimethoate, anti-aphid, cypermethrin, dichlorvos, pay attention to the alternate use of pesticides to avoid resistance. Cloth should be sprayed with clothianidin when the population density is low.

Ladybugs on beans should be prevented with a strong base agent.

Thank you. You're welcome <> than heart].

Summary. Ladybug can be killed with the following 6 drugs, namely: trichlorfon, ethyl spinodidamycin, azolfenamide, cyantraniliprole, enyldimidamin, avermectin.

Seven Star Ladybug can kill the only group with the following 6 kinds of drugs, namely: trichlorfon, ethyl carethicidin, azole tangeramide, cyantraniliprole, enyldimidamin, avermectin.

1. Trichlorfon It is an organophosphorus insecticidal agent, soluble in water and organic solvents, and its properties are relatively stable, but in case of alkali, the water is dispersed and dissolved into dichlorvos, and its toxicity increases by 10 times. Its toxicity is mainly acute poisoning, and chronic poisoning is less.

2. Ethyl spinosadin: the appearance is white powder, ethyl spinosadin-L (the appearance is white to yellow crystals, with bitter almond flavor.

Thank you for your inquiry.

I wish you a happy life and all the best.
