What are the control methods of large cherry fruit flies?

You can use plant-specific insecticides, spray evenly on plant leaves, and do not water during the medication. It is also possible to re-tiln the garden soil and spread it with new soil. This will eliminate all germs.

How do large cherries prevent fruit flies? Have you tried any of these tricks?

How do large cherries prevent fruit flies? Have you tried any of these tricks?

In general, the emergence of fruit flies is climate-dependent, and mid-to-late maturing varieties of cherry varieties are particularly susceptible to damage, so early harvesting methods can be adopted to avoid insect infestation. On the other hand, fruit flies need a high temperature environment to breed, so it is necessary to do a good job of shading and sheltering from rain in summer to reduce the chance of fruit flies.

It is trapping, there are many ways to trap, the simplest way is to use a sticky insect board, the density of the insect board should not be too low, generally 4 trees need to hang a worm board, generally at least once a week. The second time, the replacement time will be slightly extended, and it will be replaced when it is full.

In fact, in the process of the development and growth of this plant, some pesticides can be used, so that it can be effectively controlled, and it will also make the big cherries grow strongly.

How to prevent fruit flies in big cherries? Have you tried any of these tricks?

1. Clean the orchard: clean the fallen leaves and dead branches in the orchard when the cherries fall fruit, and then stack the fallen fruits to trap the fruit fly adults. 2. Hang insecticidal lamps:

Use insecticidal lamps and sticky insect boards to trap fruit flies. 3. Spraying agents: spraying insecticides every other week after inducing adults.

4. Strengthen management: regular ventilation in the season of high temperature and rain.

1. Clean the orchard

When controlling cherry fruit flies, you can start from the peak of each fruit fall, clean the orchard once a day, remove the fallen leaves and dead branches, destroy the breeding and growth environment of fruit flies, and pile up the fallen fruits and rotten fruits in a centralized manner, and then spray the vidamine agent to remove the larvae, and then use the taste of fruit drop fermentation to trap and kill fruit flies.

2. Hang insecticidal lamps:

Fruit fly adults have phototaxis, in the prevention of cherry fruit flies, you can hang insecticidal lamps in the orchard, paste sticky insect boards or use traps to attract adult fruit flies and kill them, but insecticidal lamps and sticky insect boards should be cleaned and replaced once a day to avoid losing their effect.

3. Spray the agent

To control cherry fruit flies, you can take the method of spraying pesticides, first buy deltamethrin, cyhalothrin and other agents from the market, and then use traps to lure adult worms, and then spray the diluted agent on the trunk and ground of the orchard, spray once every other week, and spray continuously for 2-3 weeks.

4. Strengthen management

Fruit fly insect pests mostly occur in high temperature and high humidity weather, in the process of breeding cherries, in the high temperature and rainy season, strengthen ventilation, maintain air circulation in the environment, reduce fruit fly breeding, and provide sufficient compound fertilizer for cherry trees, improve their disease resistance, and avoid fruit flies from approaching.

<>1. Do not purchase seedlings from epidemic areas. 2. Turn over the soil, clean up the orchard, and shovel out weeds and garbage before the fruit flies overwinter and emerge, or during the period when the cherry fruit is enlarged and veraison. 3. Prepare sweet and sour liquid to trap fruit flies.

4. Hang insect trap lamps or insect trap yellow plates in the ground to eliminate fruit flies. 5. Mix the insecticide with the soil. 6. Suffocate insects by mulching with film, and remove insect fruits, fallen fruits and rotten fruits in the orchard in time.

First, the control method of cherry fruit fly

1. Strengthen inspections and do not purchase seedlings from epidemic areas. Before selecting seedlings, you can do some research in advance and pay attention to precautions.

2. Because fruit flies will enter the soil and cocoon after they are old and mature, they can turn the soil, clean up the orchard and shovel out weeds and garbage before the fruit overwinters and emerges, or during the period when the cherry fruit is enlarged and veraison.

3. Use brown sugar, vinegar, fruit wine, orange juice and water (:1:1:1:10) to prepare sweet and sour liquid, and trap fruit flies before wintering and featuring.

4. You can hang an insect trap lamp every 30 acres, or hang about 20-30 insect trap yellow boards per mu to kill fruit flies.

5. The soil can be treated with pesticides before the overwintering adult emergence, before the fruit swelling and veraison, and can be sprayed with 5% phoxanthion EC 1000 times, and then mixed with a tooth rake.

6. Mulch film covering method is used to suffocate the larvae. During the ripening period of the fruit, according to the actual situation, the insect fruits in the orchard can be removed every 5 days or so, and the fallen fruits and rotten fruits should be picked up, buried in a centralized manner or destroyed with water.

Second, when is the fruit fly control effect good?

1. Cherry fruit flies are generally pesticide-treated in the initial stage of pests, and the effect is better.

2. When planting cherries, it is necessary to keep the soil moist, and generally water before the germination stage, fruiting period, fruit expansion and winter.

3. Cherries need appropriate nutrients during planting, and some base fertilizer and other trace elements can be added to the soil.

4. Cut off the dead branches and yellow branches on the cherry tree, and clean up the orchard after the leaves are dropped, and the stone sulfur mixture can be used to kill the eggs.

In the peak stage of adult eugenation and oviposition, the plants are sprayed with chemical agents (40% Yakinosta, 80% dichlorvos or 90% trichlorfon) and mildew bait, and the pesticides are used to kill the adult insects.

Spraying the canopy every 5-8 days for 1 month can also have a certain control effect. The most important thing in chemical control is to grasp two points: the screening of chemical agents, according to the behavioral and biological characteristics of the large fruit fly of Xiangtang, select the most suitable period for the prevention and control of pesticides, so that the control effect can achieve the best effect.

The adults of citrus fruit fly have a strong ability to migrate in close proximity, and the control effect of spraying chemicals is not ideal, and the chemical control technology is not suitable for large-scale pest control. In the actual operation of the control of citrus fruit fly in orange orchards, most of the methods of spraying plants are used to achieve the purpose of killing the adults of citrus fruit fly.
