Why do blueberries grow in fruit flies, and what are the symptoms? Can it be prevented?
Blueberry fruit flies are an insect of the diptera fruit fly family that destroys the fruit of blueberries by eating small insect moths. Adult insects are generally around 2.5 mm, the production of ovaries is in the ripening stage or close to the ripe fruit stage of the outer skin underneath, hatching small insects moth fruit for harm, after growing up will break the skin of the fruit out, the skin of the fruit will appear bug bite hole, mild words will affect the quality and quality of the fruit, serious time will lead to fruit fall. In the past ten years, the temptation potion of sugar and vinegar has been studied through different formulation ratios, and the temptation round-up experiment for blueberry fruit flies has been carried out, and the effect is obvious. The material and method is a blueberry science and technology demonstration garden in Guizhou that took about ten years to study the blueberry fruit tree, and the agents that provided the test were about 90% of the enemy insects, as well as brown sugar, vinegar and 50% of the liquor. The lure potion is made from a five-hundred-milliliter plastic bottle in a bottle, with two small openings of five centimeters multiplied by three centimeters on either side of the middle part of the bottle. The test is divided into four treatment methods, such as the proportion of lure agents one to three and the proportion of water, etc., and the proportion of sugar, vinegar, alcohol, water, and insects in the first to third of the temptation agents is between 35 percent, 30 percent, 50 percent, zero percent, and 0.5 to 1 percent, respectively.
Preventive treatment of blueberry drosophila
The flies that harm blueberry fruit are mainly black fruit flies. It grows into a bug and then produces the eggs under the skin of the nearly ripe blueberry fruit and under the outer skin of the soft and rotten fruit, the young eggs will become small bugs after hatching, and as the small insects eat, the fruit gradually becomes soft, brown, and finally rots, falling off the fruit tree. In fact, it only harms near maturity and after maturity, there are blueberry fruits that begin to rot, and the higher the maturity, the more serious the damage. Another blueberry fruit can be destroyed by multiple fruit flies at the same time and leave many small holes in the outer skin of the fruit. In normal years, fruit flies appear and destroy from mid-June to late August. There is a lot of reproduction, and the overlap is very serious. This is obvious for the production quantity of blueberry fruit trees.
Remove rotten organic matter and harmful substances in and around the orchard, and carry out deep soil turning or covering the soil to minimize odor, so as to reduce the temptation of fruit flies to concentrate on the fruits in the cold shed. At the same time, the application of 50% of the fly exterminating agent to the surrounding grassland hillside wasteland, stinky ditches, and manure fertilizer can suppress the basic method of resisting the source of insects. During the entire fruit picking period, the hygiene of the basic fruit field should be maintained to avoid wild grass growth, and the surrounding environment of the basic fruit field should always be paid attention to keeping clean. Environmental hygiene controls are completed by June 5 of each year. Avoiding premature ripening of blueberry fruits in the field can reduce the temptation to fruit flies and reduce damage. During the harvest period during the ripening period, the fallen fruits and rotten fruits inside and outside the orchard should be cleaned up, so as to avoid the destruction in the orchard after the survival and reproduction of the fruit flies.
The ratio of brown sugar, vinegar, liquor and water is one to two to four or sugar, vinegar, wine and water is 1.5 to 1.5 to 1.5 and is packed in small mineral water bottles. Open two small holes of one centimeter in the middle of the small mineral water bottle, put in 100 ml of sweet and sour juice, and the mouth of the bottle should be tightly covered. Hang the bottle on the strong branches of The kang, thirty centimeters from the ground, and place it according to the style of the chessboard, and hang about thirty bottles on one acre of land.
The frozen greenhouse and the open-air intersection area are to be hung in the open shed, the bottle needs to be hung between June 3 and June 8, and the individual open-air picking area is completed within three days after the fruit changes color according to the microclimate of the variety and region. Remove bugs from the bottle regularly and add or change the sweet and sour juice every week. After the harvest of fruits is over, the hunting of sweet and sour juices should be stopped. After the appearance of fruit flies, the base should observe it, select the appropriate fruit to soak in salt water every day, grasp the degree of damage to it, and facilitate the adoption of other measures to prevent it.
First, use fly exterminators to stir well with the soil, increase the appropriate amount of sweet and sour juice to stir into poisonous soil, sprinkle on the wasteland on the grassy hillside, stinky ditches, manure fertilizer on the other side of the dirty and messy places, each time at intervals of seven to ten days. When stirring toxic soil and sprinkling, be sure to wear rubber gloves and wash well with hand sanitizer after the end. Be careful not to get blueberry fruit trees and fruits, but also away from drinking water and irrigation water, to avoid polluting water sources and pesticide residues, resulting in very serious consequences.
Summary: The above content is to introduce the blueberry growth of fruit fly disease, it is recommended that we must be careful and careful in the daily management, can improve the conditions between some fields, is conducive to the better growth of fruit trees, when the disease occurs, you must also take the fruit trees with diseases out of the field for incineration or buried deep in the land, but also can use some agents to spray, to achieve the effect of treatment.
