[0002] Grape fruit has thin skin, thick pulp, sweet taste and high juice content, and is popular in the market. Grape is planted in many places in China, and grape production has become a pillar industry in many regions of China. Grape is susceptible to various diseases and pests during the growing season, such as fruit flies, leafhoppers, thrips, sour rot, gray mold, and anthracnose. Among them, fruit flies mainly harm grapes during the mature period, adult females lay eggs in the skin of grape fruits, and the larvae hatch and feed on the fruits, seriously affecting the commercial value of the fruits. Mature grapes are about to enter the market, and chemical pesticides should not be used for food safety reasons. Fruit fly control during the mature period of grapes is a problem that needs to be solved in current grape production in southern China.
[0003] Fruit fly adults are small and hidden, and are not easy to detect when they occur, so it is difficult to control. Using the tendency and habits of fruit flies for trapping is an effective means of fruit fly control in grapevines. Sticky boards and insecticidal lamps have been used to trap fruit flies, but due to their high cost, they are difficult to popularize. How to provide a fruit fly trapping agent that is simple to operate, low in cost, effective in trapping, and friendly to the environment has become one of the key problems that need to be solved in grape production in southern China.

BRIEF DESCRIPTION OF DRAWINGS
[0014] Figure 1 It is a waste plastic bottle modified into a trapping bottle.
[0015] Figure 2 It is a diseased grape paste juice mixed with a volume fraction of 45% ethanol solution, 50 g / L acetic acid solution, and water in a ratio of 4:1:3:10 to form a trapping agent. DETAILED DESCRIPTION
[0016] The following examples are further illustrations of the present application, but not limitations thereof.
[0017] The grape fruits in the following examples which were damaged by diseases (hereinafter referred to as susceptible grape) were grape fruits on grape clusters which were infected by diseases such as gray mold, anthracnose, sour rot and the like in a vineyard.
[0018] The method for making the trap bottle in the following examples was as follows: the upper part (referred to as upper part, and the remaining part referred to as lower part) of a plastic bottle (about 500 mL) was cut off at 5-7 cm below the bottle opening with scissors, two holes were punched on the upper part and the lower part of the bottle respectively, the upper part was placed in the lower part with the bottle opening facing down as a "funnel", then a thin rope was strung on it, and the lower part was completely wrapped with yellow paper (fruit flies have a tendency to yellow), to make a trap as shown in Figure 1 .
[0019] Example 1: Comparison of the trapping effects of different fruits on fruit flies Several main fruits (all mature) in the south were taken as objects, which were grape, peach, pear, citrus, blueberry, loquat and apple, and the soluble solids content of different fruit fruits was determined by a portable sugar meter, wherein grape was set as two treatments of healthy grape and susceptible grape (mature healthy and susceptible 'Summer Black' grape clusters were collected from the field of the vineyard, and the soluble solids content was ensured to be more than 16% by mass fraction), and the other several fruits were all healthy fruits, which were purchased from a fruit trading market (Table 1). The fruits of different fruits were mashed into paste juice, the paste juice, a volume fraction of 45% ethanol solution, a 50 g / L acetic acid solution and water were mixed uniformly at a volume ratio of 4:2:3:10, then 1 drop (0.5 mL) of detergent was added (the purpose was to destroy the surface tension of water, so that the fruit flies could not escape after contacting), to configure into a trapping agent. Pour into the modified trap bottle, and hang in the vineyard (the trap bottle is 1.5 meters high from the ground, and the adjacent trap bottles are spaced more than 12 meters apart, 5-6 trap bottles filled with trapping agent are placed per mu of land), and the number of fruit flies in the trap bottle was investigated and recorded after 5 days. Each treatment had 5 replicates.
[0020] Table 1: Field trapping effect of different fruits on fruit flies Note: In the same column of the table, different letters indicate significant difference (P<0.05), and the same letter indicates no significant difference.
[0021] As can be seen from Table 1, under the same component allocation ratio conditions, the trapping effects of different fruits on fruit flies were significantly different, wherein the number of fruit flies trapped by the two grape treatment groups was significantly higher than that of the other several fruits. The soluble solids content of grape fruits was significantly higher than that of the other several fruits, and the content was not less than 16% by mass fraction, while sugar was the main component of fruit soluble solids, i.e. the sugar content of grape fruits was higher than that of other fruits. Therefore, the grape clusters infected by pathogenic bacteria were used as the preparation material of the trapping agent in the subsequent test.
[0022] Example 2: Comparison of the trapping effect of different grape components on fruit flies To select the optimal grape juice component content, the diseased grape fruits collected from the field were crushed into paste juice, and then mixed according to the six proportions in Table 2 (volume ratio of diseased grape paste juice, 45% ethanol solution, 50 g / L acetic acid solution and water = 0:5:2:3:10), followed by adding 1 drop (0.5 mL) of detergent to prepare the trapping agent, which was hung in the field for trapping. The specific trapping method was the same as that in Example 1. The investigation results after 5 days (Table 2) showed that the trapping effect of the trapping agents with different contents of diseased grape paste juice on fruit flies was significantly different. With the increase of the content of diseased grape paste juice in the trapping agent, the trapping effect on fruit flies gradually increased. When the volume fraction of the diseased grape paste juice reached "4", the trapping amount of fruit flies reached 165.8 per bottle (treatment 5). Subsequently, the proportion of the diseased grape paste juice in the trapping agent was further increased to "5" volume fraction, and the trapping effect on fruit flies was not significantly different from that when the volume fraction of the diseased grape paste juice was "4" (treatment 6). Therefore, the content of the diseased grape paste juice was selected as "4" volume fraction for the next formula screening.
[0023] Table 2 Field trapping effect of different grape components on fruit flies Note: Juice is the paste juice of diseased grape, wine is 45% ethanol solution by volume, vinegar is 50 g / L acetic acid solution; the same column in the table indicates significant difference (P<0.05), and the same letter indicates no significant difference.
[0024] Example 3: Comparison of the trapping effect of different ethanol components on fruit flies After the content of the mushy juice of diseased grape and the volume fraction 45% ethanol solution was determined, the content of acetic acid in the formula was further screened. Specifically, the volume ratio of the mushy juice of diseased grape, the volume fraction 45% ethanol solution, the 50 g / L acetic acid solution and water was 4:1:0-4:10 according to Table 4, then 1 drop (0.5 mL) of washing-up liquid was added to prepare the trapping agent, which was hung in the field for trapping. The specific trapping method was the same as that in Example 1. The investigation results showed that the trapping agent had a certain trapping effect on fruit flies when the content of the volume fraction 45% ethanol solution was 0 (treatment 1), which might be related to the fact that the diseased fruits released a certain amount of volatile substances such as ethanol during the rotting process. When the volume fraction of the volume fraction 45% ethanol solution was 1, the trapping agent had a good trapping effect on fruit flies (treatment 2), and further increasing the content of the volume fraction 45% ethanol solution did not obviously improve the trapping effect (treatments 3 and 4). Therefore, the formula with the volume fraction of the volume fraction 45% ethanol solution being 1 was selected for the next formula screening.
[0025] Table 3 Trapping effect of different ethanol component contents on fruit flies in the field Note: Juice is the mushy juice of diseased grape, wine is the volume fraction 45% ethanol solution, and vinegar is the 50 g / L acetic acid solution. In the same column of the table, different letters represent significant differences (P<0.05), and the same letter represents no significant difference.
[0026] Example 4: Comparison of trapping effects of different ethanol component contents on fruit flies After the content of the mushy juice of diseased grape and the volume fraction 45% ethanol solution was determined, the content of acetic acid in the formula was further screened. Specifically, the volume ratio of the mushy juice of diseased grape, the volume fraction 45% ethanol solution, the 50 g / L acetic acid solution and water was 4:1:0-4:10 according to Table 4, then 1 drop (0.5 mL) of washing-up liquid was added to prepare the trapping agent, which was hung in the field for trapping. The specific trapping method was the same as that in Example 1. The investigation results showed that the trapping effect of the trapping agent on fruit flies gradually increased with the increase of the content of acetic acid component, and when the volume fraction of the 50 g / L acetic acid solution was 3, the trapping amount of fruit flies reached 163.2 per bottle (treatment 4), and further increasing the content of acetic acid component did not obviously improve the trapping effect on fruit flies (treatment 5). Therefore, the formula with the volume fraction of the 50 g / L acetic acid solution being 3 was selected for the preparation of the trapping agent.
[0027] Table 4 Trapping effect of different acetic acid component contents on fruit flies in the field Note: Juice is the juice of diseased grape, wine is 45% ethanol solution, vinegar is 50 g / L acetic acid solution; the same column in the table, different letters represent significant difference (P < 0.05), the same letter represents no significant difference.
[0028] In summary, when the volume ratio of juice of diseased grape: 45% ethanol solution: 50 g / L acetic acid solution: water is 4-5: 1-3: 3-4: 10, the fruit fly trapping agent has better fruit fly trapping effect, and when the volume ratio of juice of diseased grape: 45% ethanol solution: 50 g / L acetic acid solution: water is 4: 1: 3: 10, the fruit fly trapping agent has the highest cost performance.
