Drosophila melanogaster, Drosophila of the family Drosophilaceae of the order Diptera, is a major pest that has been damaging to fruits in recent years. The pests are distributed in all continents of the world, and Drosophila melanogaster is one of the main species harmful to fruit trees. In recent years, the harm of drosophila melanogaster is on a trend of increasing, and hosts are wide, including more than 60 plants such as grapes, cherries, strawberries, blueberries, blackberries and the like. In addition, the drosophila melanogaster is easy to cause pathogenic bacteria infection in the wounds caused by fruit damage, for example, the drosophila melanogaster plays an important role in the occurrence of grape acid rot, and the secondary damage of the drosophila melanogaster seriously affects the yield and quality of fruits and causes great economic loss, so that the effective prevention and control of the drosophila melanogaster is very urgent.
At present, the control of the drosophila melanogaster is mainly based on chemical control, the chemical control is quick and effective, but the pest period of the drosophila melanogaster is mainly the fruit maturation period of fruit trees, and the pesticide is easy to remain in the fruit, thereby causing unnecessary influence on the production and eating of the fruit trees. The environmental pollution, residue and the defect of the pesticide on animals and pollinating insects are the biggest obstacles for the safe and effective prevention and control of the insects.
Physical control is a main research direction in China in recent years, but the existing physical control effect is still poor. How to provide a black belly drosophila attractant which has good control effect, no pollution to fruits and no pollution to the environment, and the problem to be solved in the control of the black belly drosophila is urgent.

Detailed Description
In order that the invention may be better understood, the invention will now be further described with reference to specific examples.
The materials and reagents used in the following examples are commercially available unless otherwise specified.
Example 1 screening attractant component formulation for field trapping trials
Respectively mixing grape volatile components isoamyl acetate and ethyl palmitate in a mass ratio of 1: 0. 9:1, 1:9 and 0:1 are respectively prepared into drosophila melanogaster attractants with different concentrations, and the drosophila melanogaster attractants are added into slow-release plastic vials (Beijing Zhongjie Sifang Limited, 3cm in length, 1cm in diameter and 0.15cm in diameter of a bottle mouth), wherein each vial is … … g to prepare the drosophila melanogaster lure core. The five proportions are respectively processing one, processing two, processing three, processing four and processing five.
Placing the drosophila melanogaster attracting core into a central hollow groove of a blue insect sticking plate, wherein the blue insect sticking plate is rectangular and has the side length of 25 x 20 cm; the black drosophila melanogaster trapper is formed, trapping tests are carried out in a trial base in scientific research of a plant protection department of a Chinese academy of agricultural sciences before grapes are ripe for 8 months, and component distribution ratios with good trapping effects under field conditions are screened.
Five drosophila melanogaster lures with different proportions are combined with a blue insect sticking plate to prepare the drosophila melanogaster trapper, and an empty slow-release plastic small bottle and the blue plate are combined to be used as a control, and each treatment is repeated for 3 times. Hanging all traps in the vineyard randomly, wherein the height of each trap is equal to the height of a grape fruit ear, and the distance between each trap and each trap is 5 m. The number of the drosophila melanogaster population 1, 2-4 and 5-7 days after the trapper is hung is counted and investigated.
The results are shown in fig. 1, and the field trapping data shows that the insect trapping amount of the five treatments is higher than that of the blank control. Day 2-4, day 4-7 traps indicated isoamyl acetate: ethyl palmitate was the best trap at 1:1, isoamyl acetate: the trapping effect was also better when the ethyl palmitate was 9:1 and 1: 0. And, when isoamyl acetate: the effect is obviously better than that of isoamyl acetate when the ethyl palmitate is 1: the effect of ethyl palmitate was 9:1 and 1:0, with significant differences.
Example 2 optimal color screening of Pepper plates
The method of example 1 was followed to produce a drosophila melanogaster lure using isoamyl acetate and ethyl palmitate 1:1, which was combined with colored plates of different colors (insect-sticking plates) to produce a drosophila melanogaster trap. The color of the insect sticking plate is selected from white, red, blue, black, green and yellow, and the method is the same as that of the embodiment 1 except that the color of the insect sticking plate is different. Hanging all traps in the vineyard randomly, wherein the height of each trap is equal to the height of a grape fruit ear, and the distance between each trap and each trap is 5 m. The cumulative population of drosophila melanogaster on the color plates was statistically investigated 1, 4, and 7 days after the traps were hung, respectively.
The results are shown in fig. 2, and the test results show that the combination of the lure and the blue color plate has the best trapping effect on the drosophila melanogaster.
Example 3 study of the duration of attracting the Drosophila melanogaster
The method is the same as that of example 1, except that isoamyl acetate and ethyl palmitate are adopted to manufacture the fruit fly luring core, and the luring core and the blue color plate are combined to manufacture the fruit fly trap. This was repeated three times. Hanging all traps in the vineyard randomly, wherein the height of each trap is equal to the height of a grape fruit ear, and the distance between each trap and each trap is 5 m. After the trap is hung, the number of the drosophila melanogaster mouths trapped by the color plates for 1 day, 2-4 days, 5-7 days, 8-10 days, 11-14 days and 15-18 days is respectively investigated.
The result is shown in fig. 3, and the test result shows that the trap still has a good trapping effect on drosophila melanogaster after being hung for 10 days, which indicates that the attractant has long lasting period.
