Background
ailanthus altissima Mill. Swingle belongs to the genus Ailanthus of the family Simaroubaceae, commonly known as Ailanthus altissima, and is named because of the presence of glandular spots emitting special odors on its branches and leaves. The ecological restoration method has the advantages of strong adaptability, high growth speed, strong tolerance and less damage of plant diseases and insect pests, is often used as pioneer tree species in loess hills and rocky mountainous areas in the north of China, but is often damaged by orbita and its kindred species ailanthus altissima in recent years, and has serious loss.
The Orthosiphon aristatus Eucrynchus Morschulsky belongs to Orthosiphon aristatus of Ardisia of family Ardisidae, has single host, mainly harms Ailanthus altissima, and is one of dangerous forestry pests published by the national forestry Bureau 2003. The orbital elephant is mainly distributed in korea abroad, is mainly distributed in provinces such as Heilongjiang, Liaoning, Xinjiang, Qinghai, Gansu, Ningxia, Shanxi, Beijing, Tianjin, Hebei, Henan, Shandong, Anhui, Shanghai, Jiangsu, Sichuan and the like in China, and currently causes serious harm to most regions in China. The 190 'national forestry dangerous pests' lists were listed by the national forestry agency in 2013.
the orbital elephant is seriously damaged by larvae, mainly damages roots, the initially hatched larvae firstly damage phloem and start to damage xylem along with the growth of the instar of the larvae, even directly damage fine roots in serious cases, and the damaged parts are often accompanied with nodular protrusions to form a colloid mixture, but the specific forming mechanism is not clear; feeding young tips, leaves and petioles of Ailanthus altissima into the eclosion adult insects for supplementing nutrition; one generation in a year, and the phenomenon of generation overlapping is serious.
The current prevention and treatment method for the orbit elephant mainly comprises the following steps: the quarantine is strengthened, and the debugging and transportation of the ailanthus seedlings from the epidemic area generated by the orbit elephant are avoided; maintenance management is enhanced, tree vigor is enhanced, and the resistance of the ailanthus is improved; chemical control adopts measures such as poison ring, root irrigation, pesticide spraying and the like, although the effect is quick, the chemical control has certain pollution to the environment; the outdoor effect of biological control by adopting beauveria bassiana is not obvious; the physical prevention and control usually adopts methods of artificial killing, blocking adult trees and the like, which not only consumes huge manpower and material resources, but also easily causes artificial damage to blocking facilities. Therefore, new approaches for preventing and treating orbital conditions are urgently sought.

Example 3
the trapping and killing test of the imagoes of the orbital elephants is arranged in the sanddam village of Wuhan tree county Wu Quzhuan, Ling Wu city, Yinchuan city, the Ningxia Hui nationality, the attractants A-F in the example 1 are injected into slow release materials (wherein, A-E have preservatives), the slow release materials are polyethylene plastic bottles, 100mL of trapping cores are injected into each slow release carrier, the slow release bottles are hung on the rainproof cover of the trapper in the example 2, all the trappers are buried in soil pits within the range of 15-40cm away from the root, the height of the trappers is adjusted to enable the upper edge of the trapper insect storage tank to be level with the soil surface, each formula is repeated for 6 times, the number of the orbital elephants in the trappers is counted every 5-6 days, the state of the trapping cores is observed and the trapping cores are replaced in time, and each observation is carried out between 8 o 10 o noon, and the test result.
The test result shows that the formula B is obviously different from the formula A, the formula C, the formula D and the formula E, the formula A, the formula C, the formula D and the formula E are not obviously different, namely the attraction amount of the formula B is the highest, 179 adult insects are attracted in the test, each trap attracts 3.0 heads for 3 days, and the attraction amount of the A, C, D, E formula in the four treatments is not higher than that of the formula B.
Comparative tests of example 3 and example 4 showed that the substance emitting apple odor was the substance having the greatest influence on the attracting effect. Apple juice is convenient and cheap to prepare, but preservatives are required to be added, and the source of the apple juice can be influenced by seasons. Therefore, esters which emit apple odour are another preferred option.
Example 4
The trapping and killing test of the imagoes of the orbits of the ditches is arranged in the sandbank village of Wuhanshu village of Firmiana trees in Lingwu city of Yinchuan city, the national Hui nationality of Ningxia, the main purpose of the embodiment is to compare the difference of trapping amount between the formula F and the formula B, the attractant in the embodiment 1 is injected into a slow release material, the blank control ck is 100ml of distilled water, a slow release bottle is hung on the rainproof cover of the trapper in the embodiment 2, all the trappers are buried in a soil pit within a distance range of 15-40cm from a root base, the height of the trapper is adjusted to enable the upper edge of the trapper insect storage tank to be level with the soil surface, each formula is repeated for 6 times, the number of the orbits of the trapping ditches in the trapper is counted every 5-6 days, the state of the trapping cores is observed, the trapping cores are replaced in time, if no change is needed, the trapping cores are not replaced, and.
Analysis of variance was performed on the three treatments, and multiple comparisons were made by least significant difference method (LSD), with very significant differences between formula F and formula B and the control. The formula F attracts 3.8 heads per 3 days on average, because the sugar-vinegar liquid is a broad-spectrum attracting core and has attracting effect on various insects, and the formula F attracts orbital elephant more specifically. And in field tests, the F formula lure core is found to have no change when the lure core is replaced on the 6 th day, the lure core is continuously used for continuous lure, the lure core changes about 30 days, and the lasting period of the lure core is preliminarily presumed to be 30 days.
example 5
An indoor Y-olfactometer test was performed to verify the results of the forest test, which was repeated 3 times for 30 adults each time, in combination with the formulation method in example 1 and the test results obtained in example 4. The test results show that the F formula and the B formula show extremely obvious difference (P is less than or equal to 0.001), so that the F formula has stronger attraction to orbital elephant, and the specific test results are shown in Table 1
TABLE 1 comparison of the attracting effect of the F and B formulations on orbital elephant (Y-type olfactometer)
