Hello friends of today's headlines! Last time, I told you about the critical period of fruit fly control, and today I will continue to talk about the effective control method of fruit fly. These methods have been tested in the field for your reference.
Fruit fly
<h1>First, sexual attractants as a means of detection</h1>
How to determine whether what happens in the fruit is a fruit fly, we can hang a trap or trap jar, which is hung with methyl eugenol, also called sex attractants, or use a yellow plate containing sex pheromones, and there is a yellow plate that does not contain pheromones. Sex pheromones are particularly sensitive to the male of the fruit fly, and when it smells this odor, it thinks that the female is here, so it will come over and introduce it into the jar. If you find adult fruit flies in the jar, then you can judge that there are fruit flies in the fruit. Once found, we must do a good job of prevention and control to avoid causing a lot of losses.
Sex pheromones, also known as sex attractants, are only effective for males, not females. But the real harm to the fruit is the female. Many of our orchards are hung this way, we should carefully observe, you booby trap male insects or female insects, do not only see the surface effect is good, but in fact, the booby trap is male insects, and female insects will still lay eggs. Therefore, this method is generally used as a means of monitoring and cannot be effectively prevented.
Real fly traps
<h1>Second, the real fly trap trap</h1>
The other is physical booby-trap, which uses a real fly trap, also known as a sticky worm ball. This armyworm ball we can hang on the canopy, just about 1 meter 5 position, so hang on it, it is colored and combined with food temptation. Fruit flies see this color and think it is a fruit, it will come to harm, as long as it falls on it will be stuck. On the other hand, there is also protein in the ball, there is a taste, and the fruit fly wants to eat and harm both, and it will not run when it is stuck. When you use it, you can tie it to a tree branch. When you use it, hang the tree first, and then open the paper to avoid sticking to your hands or branches and leaves. This one can be killed by both female and male insects. Two days ago, a friend who was a grower hung a ball on a tree and stuck a bird, so it was sticky. This ball will not dry for half a year and is very resistant to rain. If the ball is already full of bugs, replace it. Because only after the fruit fly sticks to the glue can it be prevented.

<h1>Third, the chemicals are sealed on the ground</h1>
Another method is chemical control. During the ripening and active period of fruit fly, spray the canopy or grass. Because adult insects are not only harmful in trees, but also in the grass or around orchards, we can kill chemical agents during this period, and we can use high-efficiency cyfcypermethrin. Because fruit flies have little resistance to chemicals, they can be killed as long as they can be hit.
Fruit fly has a characteristic, that is, it is good at flying, so it cannot be completely killed. Even if you kill the fruit flies in your own orchard, the fruit flies in the next orchard will fly over to spawn. Therefore, it is also necessary to add ground sealing, using chlorpyrifos or some other agents, such as high-efficiency cyfluthrin or high-efficiency cypermethrin plus some propyl bromophos and other spraying on the ground. After pupae are unearthed, adult insects that come into contact with the potion or pupae can be killed.
But there are some drawbacks to both methods. Fruit flies are seriously harmful in the late stage of fruit, so it is easy to cause residues to exceed the standard during this period, which has some impact on the quality of our fruits. Therefore, we try to avoid the use of chemical pesticides in the later stages of fruit growth, or use them during safe intervals.
Spraying
<h1>Fourth, food booby-traps</h1>
Now let's talk about food booby-traps, such as bait, which is now renamed Cong Green, male and female seduction, booby traps, and specializes in killing orange small fruit flies. Applying cong green to the canopy and branches like toothpaste, generally using 2 grams, will attract a large number of fruit flies to eat here. An acre of land to select 40 drug release points, just the amount of one drug. If you are not sure if there are any fruit flies in the orchard, you can use the method of hanging the lure bottle. You don't need to hang the whole garden, just hang a few points. If fruit flies are detected to come in, then large-scale prevention and control can be carried out, which can save some costs and have a good control effect. Putting the booby trap into the bottle, punching some holes in the bottle, and then making a trap to hang on the branch, the lure effect on the fruit fly is also very good, and put in the bottle, the medicine will take longer.
As long as you have fruit flies in your orchard, you can usually see them coming over in 3 to 5 minutes to eat. Fruit fly will not die immediately after contact with this potion, but he will spread this potion further to other bugs, so the control effect is very good! However, Cong Green has no effect on the big fruit fly, melon fruit fly and fruit fly, and specializes in killing orange small fruit fly. Because at present, the harm that occurs on fruit trees in the south is mainly orange small fruit flies, and large fruit flies occasionally occur in local areas, so it is necessary to choose agents according to what happens in the orchard.
How do you distinguish between a small solid fly and a large fruit fly? The body length of the mature fruit fly is relatively large, 1.5 cm to 2 cm long, the color is relatively light, and there are U-shaped yellow spots on the back, which occur in Sichuan, Guangxi, and Guangdong, mainly on citrus, and occur once a year. Adults lay eggs in the fruit and hatch in 2-4 days at room temperature. The orange small fruit fly is more serious than the large fruit fly, the color is relatively dark, the harmful crops are more, and the generations overlap and generally occur in the south. Adults lay their eggs on the host fruit, there are no yellow spots in the middle of the U-shaped middle on the back, the larvae feed on the flesh in the fruit and develop and grow, the larvae go out from the fruit and merge into the soil pupae after ripening, and the adults feather out in the soil. In addition, there are melon fly, which mainly harm melons, such as melons, melons, bitter melons and so on. On top of passion fruit, it is a mixture of orange fruit fly and melon fruit fly.
Another food trap is called Gorit Fruit Fly Trap, its active ingredient is avermectin, which contains highly effective lure proteins, which can be sprayed directly on the canopy. It can control melon fruit flies, citrus tree orange small fruit flies and orange large fruit flies, bayberry trees and banana tree fruit flies, and can kill both female and male insects. At the same time, it has a sustained release technology, and the duration of the agent on the leaves after spraying can reach 7 days. Beat 180 grams per acre of land and dilute 2 to 3 times. For example, put 180 grams of gorit into a 500 ml mineral water bottle and fill it with water. Spraying 10 to 15 points on an acre of land is enough, there is no need to spray the whole garden, nor does it need to spray each canopy, each point is about half a square meter, sprayed to the front and back of the leaves. Generally spray once in 6 to 7 days, and spray 6 to 8 times continuously can effectively control fruit flies.
<h1>summary</h1>
Hang a trap or trap can, which is placed methyl eugenol, also called sex attractants, or use yellow plates containing sex pheromones, but can only attract male insects, so these can only be used as a means of monitoring, can not effectively control fruit flies. The use of real fly traps, also known as armyworm balls, will attract fruit flies both want to eat and harm, and when they are stuck, they will not be able to run, and both female and male insects can be killed. Ground sealing with chemicals, spraying pupa feathers unearthed, adult worms exposed to the potion or pupa contact can be killed. Cong Green can only booby trap orange small fruit fly, the effect is good. Gorit can trap and kill orange small fruit flies, orange large fruit flies, melon fruit flies and fruit flies, which can be effectively prevented and controlled. Therefore, everyone should choose a medicine to control fruit flies according to the actual situation of their own homes.
