BRIEF DESCRIPTION OF THE DRAWINGS

[0014] none DETAILED DESCRIPTION Below, the technical scheme in the embodiment of the present invention will be clearly and completely described in combination with the contents in the embodiment of the present invention. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention. All raw and auxiliary materials, reagents and equipment selected in the present invention are conventionally selected in the field of this technology. The % involved in the present invention is weight percentage unless otherwise specified.

[0015] Example 1: Alashan flat-faced aphid fly adult attractant and its application The invention provides an attractant for adults of Alashan flat-faced aphid flies. The formula of the attractant comprises benzaldehyde, caryophyllene, limonene and eugenol.

[0016] Preferably, the formula of the Alashan flat-faced aphid fly adult attractant comprises, by weight, 3 to 5 parts of benzaldehyde, 2 to 4 parts of caryophyllene, 1 to 3 parts of limonene, and 3 to 5 parts of eugenol.

[0017] More preferably, the Alashan flat-faced aphid fly adult attractant formula comprises, by weight, 3 parts of benzaldehyde, 2 parts of caryophyllene, 1 part of limonene, and 3 parts of eugenol.

[0018] At the same time, the invention provides an application of an attractant for adults of the Alashan flat-faced aphid fly.

[0019] Preferably, the application of the Alashan flat-faced aphid fly adult attractant uses a slow-release bottle as a carrier, adds the configured Alashan flat-faced aphid fly adult attractant into the slow-release bottle, and uses a trap formed by combining it with a yellow sticky insect board for trapping.

[0020] Furthermore, the present invention provides an application of an Alashan flat-faced aphid fly adult attractant in the preparation of pest control drugs for Cistanche deserticola planting areas.

[0021] Preferably, the use of the Alashan flat-faced aphid fly adult attractant in the preparation of pest control drugs for Cistanche deserticola planting areas is to hang the traps on branches on the south side of the Haloxylon ammodendron tree at a height of 1 / 3 of the ground, with adjacent traps more than 15 m apart, replace the yellow sticky insect board every 3 days, and replace the attractant every 9 days.

[0022] Example 2: Olfactory response of Alaska's flat-faced aphid fly to volatiles of host plants Selection of volatiles: Four substances in the fleshy stems of Cistanche deserticola, namely eugenol, benzaldehyde, caryophyllene, and 2-methyl-3-octene, and four substances in the inflorescence, namely limonene, hexadecane, hexanal, and 1-chlorododecane, a total of 8 volatiles were selected for the experiment.

[0023] Test insect rearing: Test insects were collected from the Cistanche deserticola planting base in the windbreak and sand control station in Alele Town, Qiemo County, Xinjiang, and the mature larvae were collected and brought back indoors for use. The mature larvae of the Alashan flat-faced aphid fly were raised individually in a culture dish, and the male and female were identified after pupation. Ten pairs of adults were raised in each insect cage with a side length of 25 cm. All test insects were raised in an artificial phenological box with conditions of 28°C, 30%RH, and a photoperiod of L / / D=14h / / 10h.

[0024] In the indoor test, 20 Alashan flat-faced aphid flies were tested as a group. One side arm of the Y-shaped olfactometer was filled with host plant volatiles, the other side arm was liquid paraffin (CK), and the main arm was placed with test insects. The absorbent cotton soaked with the volatile substances of Cistanche deserticola to be tested was placed in the trap bottle (the test substance was changed every 2 hours during the test), and the air flow rate in the test arm was 0.4 L·min -1 The airflow passes through activated carbon filtration, washing bottle wetting, flowmeter, trap bottle containing volatiles and three-way pipe connected to the pear-shaped bottle to reach the test insects. Female and male insects are tested separately, and the adults are placed in the central insect chamber of the Y-shaped olfactometer. One adult is placed each time, and its choice behavior is observed and recorded. When the adult enters the pear-shaped bottle, or crosses 2 / 3 of an arm and stays for more than 30 seconds, it is judged that the test insect has chosen the odor source on that side; if the adult does not make a choice in the introduction tube for 5 minutes, it is considered as no response. After each test of one insect, the insect chamber is blown with a hair dryer for 5 minutes to remove possible residual volatiles. After every test of 5 insects, a new reagent-containing absorbent cotton is replaced, and the treatment and control are swapped to reduce the possible influence of the odor source and orientation on the choice of the adult. Three concentration gradients are set for each volatile (stock solution, 10% solution and 1% solution, diluted with liquid paraffin), and each concentration gradient is repeated 3 times. After each test, all pipes of the olfactometer were flushed with ethanol (analytical grade, 75%). The test was conducted at room temperature of 25-30°C, with a homemade dark box and uniform natural light above the olfactometer to prevent other light from affecting the behavioral test.

[0025] Example 3: Analysis of the olfactory response of Alaska's flat-faced aphid fly to volatiles of host plants The female insects showed the strongest reaction rate to 1% benzaldehyde solution. The reaction rate of caryophyllene to the original solution was the highest at 48.33%, which was significantly higher than that of hexanal, 2-methyl-3-octene, benzaldehyde and 1-chlorododecane ( P =0.029, P =0.004, P =0.001 and P =0.001); the reaction rate of benzaldehyde in 10% solution was the highest at 33.33%, and there was no significant difference among the eight volatiles ( df =7, F =2.752, P =0.067); the reaction rate of benzaldehyde in 1% solution was the highest, significantly higher than that of the other 7 volatiles ( df =7, F =7.170, P =0.001). After multiple comparisons, it was found that the female insects had a higher reaction rate to benzaldehyde, which had no significant difference with caryophyllene and eugenol ( P =0.715 and P=0.105). In addition, the concentration had a great influence on the selection of A. alashanensis. Among the eight volatiles tested, the different contents of active ingredients caused significant differences in the selection of A. alashanensis.

[0026] Table 1: Behavioral responses of sexually mature female insects to volatiles from different organs of Cistanche deserticola

[0027] Note: The data in Table 1 are mean ± standard deviation. Different lowercase letters after the data in the same column represent the difference in reaction rate and corrected reaction rate of the same volatile at different concentrations. Capital letters represent the difference in reaction rate and corrected reaction rate of different volatiles at the same concentration. P =0.05 indicated significant differences in levels, and the least significant difference method (LSD) was used for the test, the same below.

[0028] The results of variance analysis showed that df1=23, df2=48, P=0.987 showed that the selectivity of male insects to caryophyllene in the original solution was the highest at 60.00%, and there was no significant difference between them and eugenol and 1-chlorododecane (P=1.000, P=0.104), but there were extremely significant differences between them and benzaldehyde, hexadecane, hexadecane, limonene and 2-methyl-3-octene (P<0.01). In the 10% solution, the reaction rates of eugenol and benzaldehyde were the highest at 38.33%, and there were significant differences between them and 2-methyl-3-octene, hexadecane and limonene (P=0.007, P=0.003 and P=0.003 respectively). In the 1% solution, the reaction rate of benzaldehyde was the highest at 46.67%, and there was no significant difference between them and 1-chlorododecane (P=0.238), but there were extremely significant differences between them and the other six volatiles (P<0.01). After multiple comparisons, it was found that the male insects had a higher reaction rate to caryophyllene, benzaldehyde and eugenol, but there was no significant difference among the three (P=0.296, P=0.861 and P=0.383).

[0029] Table 2: Behavioral responses of sexually mature male insects to volatiles from different organs of Cistanche deserticola

[0030] Example 4: Using a single factor to attract Alashan flat-faced aphid flies in the field Based on the records in the above-mentioned embodiments 1 to 3, according to the olfactory selection experiment, 8 volatiles that have a positive attraction to the Alashan flat-faced aphid fly were selected for field trapping experiments, starting before the peak of adult appearance, and lasting for 15 days in 5 different test plots in Ajiele Town, Qiemo County, Xinjiang. 1 mL of each volatile was selected and added to a slow-release bottle, and the yellow sticky insect board and the slow-release bottle were used to trap in the field, and the trap was hung on the north side of the Haloxylon ammodendron tree 1.0-1.2 m above the ground. The interval between the traps of the same volatile substance was at least 15 m, and the interval between the traps of different volatile substances was 200 m. Each treatment was repeated 5 times. After hanging, the number of adults of the Alashan flat-faced aphid fly on the trap was observed every 3 days, and the yellow board was replaced at the same time, and the male and female adults were recorded separately, and a total of 15 days were recorded.

[0031] There are some differences in the attracting effects of different volatiles on the adults of Alashan flat-faced aphid fly in the field ( df =9, F =23.556, P <0.001). Among them, caryophyllene and eugenol had stronger attractant effects, with a total number of 337 and 329 trapped in each trap in 15 days, and an average of 13.48 and 13.6 trapped. The order of the trapping effects of the eight volatiles and their mixtures on adults every 3 days was eugenol> caryophyllene> limonene> benzaldehyde> 2-methyl-3-octene> mixture> hexadecane> CK> hexanal.

[0032] A one-way ANOVA analysis of the average trapping volume over 3 days showed that there was no significant difference between eugenol and caryophyllene ( P =0.855), but compared with other volatiles and CK, there were significant differences; the capture rate of adults by 1-chlorododecane and hexanal was lower than that of CK, and there was no significant difference in the capture rate of Alashan flat-faced aphid fly compared with CK ( P =0.362), the trapping amounts of other volatiles and mixtures were higher than those of CK, and the next step is to screen different formulas to optimize the trapping effect.

[0033] There are some differences in the attracting effects of volatile field attractants on males and females. Caryophyllene has a stronger trapping effect on female insects, with an average of 7.32 insects per trap, followed by eugenol. Eugenol has a better attracting effect on male insects, with an average of 9.12 insects per trap, followed by limonene. Variance analysis shows that the number of female insects attracted by caryophyllene is significantly higher than that of male insects. There are significant differences between the sexes in the selectivity of female and male insects for eugenol, limonene, caryophyllene, 1-chlorododecane, and benzaldehyde, but no significant differences for other volatiles. In the field, eugenol and caryophyllene have better attracting effects.

[0035] Table 4: The trapping effects and parameters of different volatile substances on female and male Alaska flat-faced aphid flies

[0036] Note: The data in the table are mean ± SD. Paired T test was used to illustrate the different selectivity of male and female insects for the same volatiles. The ratio of each volatile in the mixture was 1:1.

[0037] Example 5: Indoor compound olfactory response of Alashan flat-faced aphid fly to host plant volatiles According to the experimental results of Example 2 to Example 4, 4 volatiles that have a significant attraction to Alashan flat-faced aphid flies in the field compared with CK are selected: eugenol, limonene, benzaldehyde, and caryophyllene for indoor compounding tests between different components, selection basis and preparation of plant-based attractant formula solution: According to the monomer volatiles attraction test, 3 fleshy stems plus 1 inflorescence volatiles are selected for compounding tests. The best attraction concentration of the 4 plant volatiles screened by the experiment for Alashan flat-faced aphid flies is used as the basis for setting 17 binary, ternary, and quaternary formulas. Each plant-based attractant formula takes 2, 3, and 4 corresponding plant volatile monomers, mixes and dissolves in 100 mL of liquid paraffin, so that the final concentrations of these various pure monomers are the same as the best attraction concentrations of Alashan flat-faced aphid flies adults. See Table 5 for details, and the prepared formula solutions are stored for standby use. The reaction of Alashan flat-faced aphid flies to compound host plant volatiles was tested using a Y-type olfactometer, and the specific test method was the same as Example 1.

[0038] Table 5: Ratio ingredients and concentration

[0039] Example 6: Analysis of the indoor compound olfactory response of Alashan flat-faced aphid fly to host plant volatiles Based on the records in Example 5 above, the indoor attractant selection after the active substances were compounded showed that the average selection rate of No. 16 was the highest, which was 67.50%, among which the selection rate of female adults reached 65.00%, especially the selection rate of male adults reached 70.00%, which was significantly higher than that of other test groups. The average selection rate of No. 1 was the lowest, which was 30.84%, and the average selection rates of the two-component ratios of No. 1-9 were lower than those of the three-component and four-component ratios of No. 10-17.

[0042] Embodiment 7: indoor optimization attractant formula Based on the records in the above-mentioned Examples 2 to 6, according to the selection of the attractant rate of binary, ternary, and quaternary compound attractants, the No. 16 ratio (benzaldehyde + caryophyllene + limonene + eugenol stock solution) was determined as the optimized formula, and a four-factor three-level orthogonal experiment was conducted. The orthogonal test factors and levels are shown in Table 7. Twenty Alashan flat-faced aphid flies were tested as a group. One side arm of the Y-shaped olfactometer was filled with host plant volatiles, the other side arm was liquid paraffin (CK), and the main arm was placed with test insects. The air flow rate in the test arm was 0.4 L·min -1 , female and male insects were tested separately, and the adults were placed in the central insect chamber of the Y-shaped olfactometer, one adult was placed each time, and their selection behavior was observed and recorded.
