I believe that many people who like to eat bayberry have encountered this problem, and the bayberry that is bought back will crawl out of the bayberry for a period of time and some small white bugs will crawl out of the bayberry, looking very disgusting, and the desire to like the bayberry is greatly reduced. In fact, this is a fruit fly, it is very common, if there is fruit in the home for a period of time, you will develop a lot of small mosquitoes of that kind, that is also fruit flies. Soak in lightly salted water before eating and the fruit fly larvae inside will crawl out. Now there are also some large bayberry bases have also taken some measures to solve the problem of bayberry fruit fly, so let's see how to solve the problem of bayberry fruit fly, so that bayberry has better commerciality.
First, a brief introduction to the bayberry fruit fly
The main fruit flies that harm bayberry in China are black-bellied fruit fly, pseudo-fruit fly, High bridge fruit fly and Imi fruit fly. The fruit fly we bought in the bayberry is a black-bellied fruit fly that harms the fruit in the field when the bayberry is ripe at 9-10 minutes. It breeds a generation in a few days under the conditions of humidity of 70%-80% and temperature of 20-25 °C, which restricts the development of the bayberry industry.
Second, the control of bayberry fruit fly
Bayberry fruit fly occurs in the bayberry ripening season, so it cannot be controlled using pesticides, and can only be controlled by physical and biological methods. The prevention and control methods are as follows:
1. Winter Garden: In addition to spraying stone sulfur compound on the whole canopy every winter, pay attention to the spraying of the ground. It is also possible to turn the soil deep before the overwintering adults of bayberry flies so that they cannot be feathered.
2, Luo tent coverage: Now there are many yangmei production areas in Zhejiang. Cover the bayberry tree with a 40-mesh insect-proof net 40 days before the arbutus harvest, and use cheap items such as moso bamboo as a support. This method basically blocks the harm of fruit flies to bayberry, does not use pesticides, and ensures the safety of bayberry fruit.
3, rain shelter cultivation: about 40 days before the bayberry ripening, cover with plastic film on the top of the bayberry tree, with moso bamboo as a bracket. This method can reduce the harm of fruit flies to bayberry fruit because the humidity can be reduced. And the use of rain-shelter cultivation can reduce the erosion of bayberry by rainwater, improve the quality of bayberry, reduce the rate of fruit fall, and use rain-shelter cultivation to extend the picking period of bayberry by about one week.
Rain shelter cultivation can be combined with tent covering, and the top of the arbutus tree is cultivated with rain protection and isolated by insect nets on all sides, which can achieve better results. It can reduce the fruit falling; it can improve the appearance quality of bayberry fruit, improve the yield of bayberry and the proportion of high-quality fruits; can extend the picking period; the picking period can ensure the smooth picking of bayberry in the rainy season. This technique is suitable for dwarf cultivation of arbutus fruit trees, and the height of the arbutus tree body is controlled below 2 meters, which is more appropriate.
4. Release fly pupae: by artificially raising a large number of fly pupae, and then release the fly pupae in the bayberry orchard, control the fruit flies in the bayberry garden through its parasitic fruit fly pupae.
