What kind of insect is the gray bug on the pomegranate tree?

A common grey flesh bug on pomegranate trees may be the mulberry worm, which overwinters in the soil as a pupae and becomes an adult when the pomegranate sprouts in April of the following year. The body color of the larvae of the mulberry inchworm is similar to the color of the bark of the tree, and it is not easy to be found, and it lies dormant during the day and feeds at night, and the mature larvae pupate and emerge at the intersection of the trunk. At the end of September, mature larvae descend from the tree and pupate in the soil near the trunk for overwintering.

The inchworm is a gluttonous pest that can spit out feces and crawl around. It can be sprayed with 800 times of 40% chlorpyrifos emulsifiable concentrate or 2000 times of 5% cypermethrin for prevention and control.

Larvae of fruit flies. Drosophila is a widely distributed insect, and this larvae may appear in some fruits with high sugar content. During the pomegranate ripening season, fruit flies are attracted to the smell of pomegranates, lay eggs on the surface of pomegranates, hatch into larvae and burrow into the pulp, feeding on the pulp.

Drosophila larvae are not proven harmful to humans in the white larval stage, but this larvae will mature as the pomegranate deteriorates, so the pomegranate should be eaten as soon as possible.

If it is an aphid, after cutting off the leaves and branches, the pomegranate tree can be sprayed with dimethoate, anti-aphid or inulin-killing agent. If it is a scale insect, after cutting off the leaves and branches, you can spray the pomegranate tree with chlorothalonil, carbendazim and dimethoate to remove insects, and the agent needs to be used continuously without interruption.

During the growth of pomegranate trees, there are black bugs on the trees, which may be aphids. Aphids damage the young treetops and leaves of pomegranate trees, lay eggs and spread large amounts of germs. If there are aphids on the pomegranate tree, the leaves and branches need to be cut off and burned, and then the pomegranate tree should be sprayed with dimethoate, anti-aphid or inulin-killing agents.

During the growth period of the pomegranate tree, there will also be scale insects on the tree, and the scale insects are also more colorful, and there are also black scale insects. Scale insects are more reproductive, but they are relatively easy to clean up and can be removed with soapy water or chili water. If there are many insects, you can use drugs such as chlorothalonil, carbendazim and dimethoate to remove insects.

During the spraying period, it is necessary to pay attention to the concentration of the agent not to be too high, otherwise it is easy to cause pomegranate trees to be harmed. Once diluted with water, it can be sprayed on the leaves and branches of the pomegranate tree, as well as the soil, to remove the eggs. The agent can not be stopped halfway, spray once in 7 10 days, and spray 3 or 4 times in a row, the aphids can be removed.

After the recovery of pomegranate trees, it is necessary to strengthen management in the later stage, and appropriate watering and fertilization should be applied during the maintenance period. According to the growth habits of pomegranate trees, reasonable maintenance can make the trees grow well and enhance the disease resistance of pomegranate trees. During the maintenance period, the pomegranate tree should be sprayed regularly, and the pomegranate tree can be sprayed once between 20 and 30 days.

Many people who live in rural areas plant a few trees in their yards or in front of their houses, and even grow pomegranates in large quantities, which is also very economical. However, in the process of picking pomegranates, it is common to find that many insects seriously affect our appetite, and for large growers, seriously affect the yield and quality. So, how do you ** these pests?

Let me explain it to you.

During the flower bud period of pomegranate trees in spring, pomegranate trees are most prone to aphids, horses and other pests, and 33% of the water can remove chlorine emulsifiable concentrate or spray into mite humidification powder.

The main pests and diseases that need to be prevented in the oilfruit stage of pomegranate are horseskin disease, cotton bollworm, scale insects, etc., and 25% Seke emulsifiable concentrate can be used for the prevention of horseskin disease in the oilfruit stage. The first generation of larvae is also germinated in early June every year, but the entire tree can be sprayed with pesticides such as Fuling.

Spodoptera exigua: Dig for overwintering pupae around the trunk before the leaves sprout.

Spraying 90% trichlorfon solution and 50% new butter solution during larval occurrence can be effectively prevented. Yellow thorn moth prevention method: winter combined with winter scissors cut the advice value.

During the larval concentration period, the orchard is inspected, and the leaves are removed to eliminate the larvae. In the larval occurrence stage, 90% of trichlorfon, 50% of infrared drugs, and liquid medicine have good preventive effects.

In the adult stage, 50% of the insecticidal pine emulsion solution was sprayed, and after the injection in the field, the 5-day insecticidal rate reached more than 90%. Spraying 50% neo-yellow phosphorus or 90% trichlorfon solution 1 2 times during the hatching period of the first generation of eggs and larvae has a good effect.

Pomegranates are prone to insects, and the pomegranate skin is thick and invisible from the outside. To prevent bugs, you can first remove the orchard, lay fewer eggs to avoid overgrowing, and spray insect repellent when the pomegranate blooms. Pruning dry and bad branches in winter will do.

The old method used to be to seal the mouth of a pomegranate with cotton. If it is not the old area of the pomegranate, there are few pests and diseases, this method is okay. If there are more pests and diseases, it is necessary to give pomegranate cloth bags to reduce losses.

Because pomegranate trees themselves are prone to insects, especially during the flower bud and fruit setting periods of pomegranate trees, insect infestations are most likely to occur. At this time, it is necessary to spray the relevant pest medicine in time.

Because the pomegranate tree is not sprayed with pesticides for a long time, the pomegranate tree itself attracts all kinds of pests, and if you don't spray pesticides for a long time, there will be a lot of pests.

Pomegranate tree insects are mainly caused by rot and are mostly diseases caused by fungi. There is no way to do it if there are already worms in the guava fruit, and it is recommended not to eat guava with long worms. When the fruit grows, the method of bagging can better prevent flying insects from flying to the fruit to lay eggs and form small worms to enter the fruit.

If it is troublesome, apply the medicine when it is flowering.

Pomegranate insects are divided into two damage stages: seedling aphid and panicle aphid, and the strategy of "picking and treating seedling aphid and main ear aphid" should be adopted. 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, 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.
