Why cherry flies occur

Generally, the spring is persistently cold and rainy. The ripening period of cherry fruit is delayed by 5-7 days compared with the normal year. The oviposition period of fruit fly adults and the hatching period of larvae are basically in line with the fruit ripening period of mid-late maturing cultivars, resulting in a significant increase in fruit pod rates.

In normal years or under normal weather conditions, when a large number of fruit fly adults appear, most of the early and mid-maturing varieties of cherry fruit have been harvested, the number of pests is small, and the harm is light. The fruit growers often ignore the prevention and control, resulting in the accumulation of worm population density in the orchard year after year. In addition to the massive cultivation of late-maturing varieties in recent years, the damage is even more serious.

The low temperature and rainy weather during the growing period of cherry fruit will reduce the toughness of fruit cortex, which is beneficial to the oviposition of adult fruit fly and the hatching of larvae. Orchard management is extensive, and the conditions of ventilation and light transmission are poor. In the middle and late stages of fruit growth, potassium fertilizer and trace elements are generally lacking. Fertilizers, etc., can also lead to poor fruit development, reduced skin toughness, and fruit cracking, which is conducive to adult oviposition and larval infestation.

Natural Sweetener

Sweeteners are Food Additives that sweeten soft drinks. Sweeteners can be divided into nutritional sweeteners and non-nutritional sweeteners according to their nutritional value. According to its sweetness, it can be divided into low sweetness sweetness and high sweetness sweetness I flavor; According to its source can be divided into natural sweeteners and synthetic sweeteners. Natural sweeteners include stevia, grosvenin, licorice, disodium glycyrrhizinate, tripotassium glycyrrhizinate and trisodium.
