2) Habits.

Under the conditions of 23 27 temperature and 75 85 humidity, aphids grow and reproduce the fastest, and can reproduce 20 30 generations in 1 year.

3) Characteristics of occurrence.

Aphids are concentrated on the underside of the leaves and on the outside of the plant.

On the first and second layers of leaves, therefore, the back of the leaves is the focus of aphid control. In addition, aphids are a very resistant pest, and the following problems must be paid attention to when using drugs:

First, the initial stage of the insect must be grasped with medication, and continuous medication must be used to prevent and control it. Biological pesticides and plant pesticides can be used continuously.

Second, the drug can not be used in a row, and different drugs that are effective for insects should be selected for alternate control.

Third, the drug must be sprayed on the whole body of the plant, focusing on the back of the leaf spray, to the leaf surface moist and not dripping.

Fourth, strictly control the concentration of drugs and use drugs standardly.

4) Prevention and control methods.

Agricultural control. increase the application of organic fertilizer and promote fitness cultivation; removal of eggs; Taking advantage of the strong positive tropism of aphids to yellow and orange, the yellow cardboard is smeared with waste engine oil, which can trap and kill winged aphids and winged aphids.

Biopesticides. It is controlled with 10 avermectin EC 3000 times or 5 antibiotic EC 800 1000 times or 1000 2000 times of avermectin EC and 1000 2000 times of bt powder.

Plant pesticides. Add 1 part of water to 1 part of the leaves of the stinky tree, soak it for 1 2 days, soak it in water and filter it, and then spray it; Soak 2 3 kg of green onions, mash them into a puree, add 15 17 kg of water, and use their filtrate; Use 5 kg of fresh peach leaves, add 500 grams of lime, 75 kg of water, soak for 1 day, scoop up peach leaves, take filter leaves and spray, the effect of anti-aphids is excellent.

Fertilizer mixed with insecticide.

With 1 urea solution and a concentration of 50 dichlorvos emulsifiable concentrate mixed spray, the anti-aphid effect is more than 98; With urine lotion: press 1:4:

400 urea, laundry detergent, water fully mixed to become a urine lotion mixture, with 30 40 kg of this liquid sprayed, anti-aphid effect of more than 98.

Chemical agent. It can be controlled with 40 dimethoate 800 1000 times liquid or 50 malathion 1500 2000 times liquid. One crop can only be sprayed once with the above-mentioned chemicals, and the last application should be 10 to 15 days away from the crop harvest to ensure that the pesticide residues in the bean are within the allowable range.

Use silver gray film to avoid aphids. Pharmaceutical prevention and control: Commonly used agents are:

50% aphid-asciopy fog wettable powder or anti-aphid carb wettable powder, 10 18 grams per mu, spray 30 50 kg of water. This agent is specially designed to control aphids, does not kill natural enemies and bees, and is especially suitable for harvesting fields. Once net or 10% imidacloprid wettable powder, the dosage per mu is 5 10 grams to 100 kg of water.

Aphids, also known as greasy insects and honeyworms, are a class of herbivorous insects that includes all members of the family Aphidoidea. There are about 4,400 species of aphids in 10 families, most of which belong to the family Aphididae.

Aphids vary in size, ranging from one to ten millimeters in length.

The natural enemies of aphids are ladybugs, aphid-eating flies, parasitic wasps, aphid midge larvae, crab spiders, lacewings, and entomopathogenic fungi (including Metarhizium aeruginosa). When it occurs sporadically on potted flowers, you can use a brush dipped in water to brush it off, but be careful not to hurt the young shoots and young leaves when brushing. The aphids under the brush should be cleaned up in time.

In winter and spring, we should often eradicate weeds in the edge of the field, spray dimethoate to eliminate aphids on the overwintering host, and reduce the source of insects.

Aphids grow in the soil and leaves of potted plants. Generally the body length is to mm, most about 2 mm. Adult aphids have wings and fly to the damp and dark places of potted plants, where they lay eggs in large quantities in the soil and other places, and after a while, the eggs will break out.

Indoor potted plants are susceptible to aphids, and it is necessary to regularly check whether there are aphids in the jujube bureau, and if you find a stool Qingrang, deal with the poor Dan as soon as possible to prevent other plants from being infected.

1. Agricultural prevention and control.

In summer and autumn, pruning is combined to prune the branches that are infested or have insects and eggs, and the new shoots that are sporadically drawn are erased during the growing season.

2. Biological control.

Protection and utilization of natural enemies, such as the scarcity of natural enemies in the garden, can also be collected from wheat fields, cotton fields or rape fields ladybugs, aphid flies and lacewings released into tomato fields, insect control, to achieve the purpose of control.

3. No pesticide prevention and control.

In the occurrence period of vegetable aphids, spraying and control, the agent can be sprayed with 20% matrine wettable powder 2000 times, or 20% pymetrozine wettable powder 4000 times, or 10% enyldimidamin wettable powder 2500 times. When spraying, the nozzle should be upward, focusing on the back of the leaves, and spraying the liquid medicine on the melon aphid as much as possible.

After the yellow plate is full of aphids, it should be replaced in time.

3. Silver-gray film to avoid aphids. Silver-gray has strong repellent properties against aphids, and silver plastic strips can be hung in the field or vegetables covered with silver-gray mulch. To control autumn cabbage aphids, you can build an arch shed of rice immediately after cabbage sowing, pull a silver-gray plastic film every meter vertically and horizontally, cover about 18 days, and sprinkle the shed when the seedlings have 6-7 true leaves.

The effect of avoiding aphids is more than 80%, and the medication can be reduced by 1-2 times.

4. Laundry detergent is out of the mix. The main ingredient of laundry detergent is sodium dodecylbenzene sulfonate, which has a strong contact killing effect on aphids.
