Carnivorous insects are the main pests of many stone fruit trees and stone fruit trees. Apple belongs to drupe fruit, and its young fruit will be harmed by different kinds of fruit eaters during the growth period, depending on the different orchards adjacent to it. If it is adjacent to the pear orchard, it is vulnerable to the harm of pear moth or pear moth; If there is a peach garden near the orchard, it is prone to peach moth or peach moth.
When the apple is in the young fruit, the moth larva eats the surface of the fruit, and as it grows, it enters the fruit to do harm. When the damage is serious, it can cause the apple to drop fruit or turn red in advance.

The efficacy of apples
1. Apples contain more potassium, which can be combined with excess sodium salt in human body and excreted. When the human body ingests too much sodium salt, eating some apples is beneficial to balance the electrolytes in the body. The phosphorus, iron and other elements contained in apples are easily absorbed by the intestinal wall, which has the functions of nourishing the brain, calming the nerves and helping sleep. Clinical application has proved that patients with depression have greatly improved their mood and relaxed spirit. After smelling the fragrance of apples, the sense of depression disappears. Experiments have also proved that insomnia patients can smell the fragrance of apples before falling asleep, which can make people fall asleep quickly and quietly. Wash and juice apples, take 100 ml each time, three times a day, and take 15 days continuously as a course of treatment. Apples can reduce cholesterol content.
2. Apple is rich in various trace elements, vitamins and other nutrients needed by human body, and it is recognized as one of the most nutritious healthy fruits. Apple seed is also called "the library of life", and its nutrient content is more than 10 times that of pulp. Apple seeds contain a lot of plant hormones, which can effectively regulate human endocrine, promote cell microcirculation and improve cell activity. [10] However, apple seeds contain the toxic substance cyanosides. Cyanosides can be hydrolyzed into highly toxic hydrocyanic acid (HCN) in acid or under the action of biological enzymes. There are hundreds of micrograms of cyanoside converted into hydrocyanic acid in each gram of apple seeds, so there is almost no possibility of poisoning. But when eating apples in daily life, we should also avoid eating the core part.
