How to rescue a dying scarab? How to control beetle?

At the turn of spring and winter, ploughing between the rows of apple trees helps to curb the growth of beetle larvae, because beetles are pests that move at night, you can take a headlamp in the apple grove, put a large pot of water under the lamp, so that the beetle is affected and falls into the water to die.

It can be hunted using its phototaxis. Use winter ploughing to freeze it to death. Of course, pesticides are generally used. However, pesticides will produce a certain amount of ***. Pests need to be flexible and master certain methods.

Goldfish are dying, it is hypoxia, and it should be changed to fresh water and feed at the extreme.

Adult beetles are light-repellent insects that can be replaced with less light or with blue light or a full white light without ultraviolet light.

1. Underground prevention and control. In the larval occurrence stage, according to the different occurrence periods of various insect pests, in.

The surface is sprinkled with phosphine granules, 3 kg and 5 kg per mu.

2. Treat organic fertilizer. The unrotted soil manure and straw contain a large number of scarab eggs.

and larvae, and most of the larvae and eggs can be killed after decaying at high temperatures, so the fruit tree is applied.

When using base fertilizer, be sure to use the decomposed soil miscellaneous fertilizer.

3. Pharmaceutical prevention and control. When adult worms occur, 90 trichlorfon and 50 malathion can be sprayed.

and other pesticides 1000 times 1500 times liquid poisoning. For larvae, use 5 chlordane powder per mu 0 5

kg 1 5 kg, mixed with fine soil 25 kg 50 kg fully mixed to make poisonous soil, evenly sprinkled.

On the ground, or spray powder on the ground, and before sowing and dismantling, the jujube is applied with pesticides, turned over with ploughing, and raked evenly. Distinct.

Scarabs should use different pesticides, and care should be taken not to cause harm to fruit trees or human bodies.

4. Booby-trap. In the orchard, a black light or fluorescent lamp is erected every 20 meters and 30 meters.

Put sweet and sour liquid to trap and kill insects with phototaxis.

5. Fruit bagging. Fruit bagging can avoid the damage of fruit in summer and autumn.

Hello! Control of beetles can control both adults and larvae.

Adult insect control: 1. Pharmaceutical control: pyrethroid and antibiotic pesticides can be selected, and Beauveria bassiana and Bacillus thuringiensis can also be used for prevention and control.

2. Light trapping: Install a black light, ultraviolet lamp or incandescent lamp in the park, and place a basin under the lamp to make the lured beetles fall into the water and kill.

3. Sweet and sour liquid (1 part of brown sugar, 2 parts of vinegar, 10 parts of water, part of wine, part of trichlorfon) booby trap pot.

Grub control: 1. Pharmaceutical control: 500-2500 grams of trichlorfon powder per mu or 2500 grams of 50% phoxanthion granules plus 25-50 kg of fine soil are fully mixed, evenly sprinkled on the ground, and then turned into the soil to poison the grubs in the soil.

2. Eradicate weeds in the nursery in time and irrigate them in a timely manner. The orchard should be deeply cultivated and ploughed before winter, so as to increase the overwintering mortality of grubs.

3. The basal fertilizer applied to the orchard must be fully decomposed to reduce the oviposition of its adults.

The control method of beetle is explained in detail, and the damage is divided into two months, and the damage of adult larvae is different.

(1) Use the habit of feigned death of adults to vibrate branches in the early morning or evening to hunt and kill small blue and white beetles, aeruginos, etc.

2) Use adult phototaxis, light to trap Scarab aeruginosa, etc.

3) Using the habit of adults entering the soil, sprinkle imidophos powder under the canopy, kilograms per hectare, and rake loose the topsoil after application, so that part of the adults who enter the soil are poisoned and die.

4) During the adult stage, spray 40% dimethoate or 50% marathon 1000 times.

(1) Select high-yield and disease-resistant varieties to plant cabbage rape as much as possible in areas with serious virus diseases.

2) Sowing at the right time and strengthening seedling management According to the local forecast, the disease will be appropriately postponed in the year of the pandemic to postpone the sowing and transplanting period to achieve the purpose of avoiding the disease. Frequent irrigation and fertilization at the seedling stage.

3) Aphid control and disease control: Before rapeseed sowing, focus on the control of aphids on the vegetable fields and weeds near the rape fields. In case of drought weather after rapeseed emergence, spraying should be sprayed to treat aphids in time, or yellow plates should be set up at the edge of the rape field to attract aphids, which can reduce the occurrence of diseases.

(1) In order to harm and occur the law, the beetle is an adult of the grub, which harms a variety of fruit trees and crops. The main damage to strawberries is the beetle aeruginosa. Scarabs are mostly active at night, biting leaves, but also harming young shoots and feeding on flower buds and fruits.

The insect occurs in one generation per year, and the last instar larvae overwinter in the soil. It mostly occurs in the summer. The insect has feigned death and has a strong tropism to black lights.

2) Control method In the plant and in the ground soil cracks, manual capture. At 7 p.m. 9 p.m., a fire was lit at the edge of the orchard to trap him. It can also be booby-trapped with a black light.

According to experiments, if a fluorescent lamp is connected in parallel next to the black light, the insect trapping effect can be greatly improved. In the harmful period, spray with 50% phosphine or marathon emulsifiable concentrate 1000 times liquid. Early control of grubs.

Scarabs belong to the order Coleoptera, the family Scarabidae.

It is also known as golden tortoise shell, blackshell insect, etc., and the larvae are called grubs, commonly known as soil white silkworms. The main species that harm mulberry trees are brown beetle, green beetle and black velvet beetle, etc., and their eating habits are miscellaneous, in addition to harming mulberry trees, they also harm apples, pears, peaches, willows and other plants. Most silkworms are distributed in most areas, with one generation a year, and one generation in two years in the north, overwintering in the soil with larvae or adults.

4 In June, the adults emerge at night and eat mulberry buds, young leaves and shoots in clusters, the adults have feigned death and phototaxis, the eggs are laid in the soil, and the larvae (grubs) eat the roots of mulberry roots and other plants under the soil.

Use natural enemies to prevent and control. Each pest has one or more natural predators, including beetles)5Artificial control.

The larvae move vertically with the rise and fall of the ground temperature every year, when the ground temperature is about 20, the larvae mostly feed at a depth of more than 10 cm, and generally climb to the surface from the depths in the early morning and dusk of summer, and bite the stems, taproots and lateral roots of bamboo willow near the ground. Dig deep under the freshly infested plants to find larvae for intensive treatment. ）

Leaf mites are commonly known as spider mites. By crawling or with the help of wind and rain and man-made carry and spreading, from point to surface, from less to more, gradually to the whole field. Leaf mites like to suck the juice on the back of the leaves, and the leaf surface initially shows green spots, and then the whole leaves lose their green and dry up and fall off, and the plant decays prematurely.

Key points of prevention and control: soil tillage and irrigation, water-drought rotation; Remove weeds from the edge of the field. The best time for chemical control is to pick and treat when spotting occurs, and choose special acaricides such as bromodilate (insecticides cannot be used, so as not to kill natural enemies and insects, so that the mite damage is getting more and more serious).

The commonly used dicofol contains DDT, which has a long residual toxicity period and cannot be reused. There are also caricidine, pyridafenone, phenbutyltin, tetramitezine, cerafenone, pyridafen, etc.

Prevention and control methods:

1.Artificial control: use the feigned death of adults to vibrate tree branches in the evening to kill adults who have fallen to the ground.

2.Physical control: Using the phototaxis of adults, hang black lights to trap adults at 7-10 o'clock in the evening.

3.Horticultural control: combined with winter ploughing, soil preparation, pick up larvae, pupae and adults.

4.Pesticide control: during the adult damage period, spray 50% methamidophos 800-1000 times, or 50% phosphine 800-100 times, 40% dimethoate emulsion 1000 times, spray every 2-3 days during the peak period of adults, and spray continuously for 2-3 days.

In this way, the harm of scarabs can be basically prevented.

It is not easy to give birth to beetles in a dry environment.
