specific Embodiment approach 1

[0012] Specific implementation mode one: the prediction method of Xinjiang wild apple sense apple small jerky worm in this implementation mode is carried out according to the following steps:

[0013] 1. Measure the diameter, bark thickness and moisture content of the middle section of Xinjiang wild apple branches;

[0014] Two, the proportion of branches with an average diameter of 30~70mm in this strain of Xinjiang wild apple in the middle section of the statistics branch is set as A%; the branch with an average bark thickness of 2~4mm in the middle section of the statistics branch accounts for the proportion in this strain of Xinjiang wild apple Proportion is set as B%; the proportion of branches with an average water content of ≥ 40% in the middle branch of the statistics branch is set as C% in this strain of Xinjiang wild apple;

[0015] Three, (A%+B%+C%) / 3=X%; X ≥ 90, this strain of Xinjiang wild apple is very susceptible to apple stinger; 90> X ≥ 80, this strain of Xinj...

specific Embodiment approach 2

[0016] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is: step 1 is carried out before the outbreak of the apple jerky pest, and the time is from May to June every year. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0017] Specific implementation mode three: the difference between this implementation mode and specific implementation mode one is: step one: the number of branches randomly selected from each Xinjiang wild apple tree is ≥10. Other steps and parameters are the same as those in Embodiment 1.

Abstract

A method for predicting Agrilus mali Matsumura infection of Malus sieversii relates to a method for predicting infection of insect attacks by the Malus sieversii. The method solves the problems that the degree of the Agrilus mali Matsumura infection of the Malus sieversii cannot be predicted at present and no efficient and convenient method applicable to field operations can be provided. The method comprises the steps that firstly, diameters, bark thicknesses and moisture contents of branch middle sections of the Malus sieversii are measured; secondly, the percentage occupied by branches of which the average diameter, the average bark thickness and the average moisture content stay within specific value scopes is calculated; and thirdly, the degree of the Agrilus mali Matsumura infection of the Malus sieversii plant is calculated and predicted. The method provided by the invention has the advantages that detection equipment only needs to satisfy low requirements; operations are easy, rapid and accurate; and a foundation is laid for protection and utilization of the Malus sieversii which is a precious wild resource.

Description

technical field [0001] The invention relates to a method for identifying the resistance of wild apples to insect pests. Background technique [0002] Xinjiang wild apple (Malus sieversii) is a plant of the Rosaceae Malus genus and a deciduous tree; it is the only natural gene bank in my country's economic forest resources and an important part of the world's wild apple gene bank. It has important scientific research and protection values. Many ancient apples The varieties are selected from this. Wild apples in Xinjiang have ecological and stress-tolerant characteristics such as drought resistance, cold resistance, and barrenness. However, due to human interference and pest damage, the natural population and distribution area of ​​wild apples in Xinjiang are decreasing, and they are on the verge of extinction. [0003] The small apple beetle, also known as apple golden beetle, spineria, and cluster beetle, has spread rapidly in wild fruit forests in Xinjiang for more than 30 ...
