Embodiment 1

[0029] Example 1 is used to illustrate the attractant of Bacteralis jujuba of the present invention.

[0030] The jujube fruit fly attractant comprises by weight:

[0031] 800 μg of nonanal, 500 μg of dipropylene glycol and 500 μg of 2-ethyl-1-hexanol.

Embodiment 2

[0033] Embodiment 2 is used to illustrate the jujube fruit fly attractor of the present invention.

[0034] The preparation method is as follows:

[0035] 1. Prepare jujube fruit fly attractant:

[0036] Each component of the attractant described in Example 1 was dissolved in 10 μL of water respectively to obtain a solution;

[0037] 2. Prepare jujube fruit fly attractor:

[0038] The high-density cotton is made into a circular lure with a radius of 1 cm and a thickness of 1 mm to 3 mm. Add the solution prepared in step 1 dropwise to the lure in sequence, and the order of adding can be arbitrary.

Embodiment 3

[0040] Example 3 is used to illustrate the application of the jujube fruit fly attractant / attractor of the present invention.

[0041] In the jujube garden of Aidinghu Township, Turpan City, Xinjiang, the lure described in embodiment 2 is suspended on the jujube tree branches 1.5m to 2 meters away from the ground, and one lure is suspended every 50 meters, and 10 lures are suspended altogether. . After 15 days, a total of 186 adults of Bacteralis cerevisiae were trapped.

Abstract

The invention relates to the field of biological attractant, and discloses a carpomya vesuviana attractant and applications thereof. The carpomya vesuviana attractant comprises nonanal, dipropylene glycol, and 2-ethyl-1-hexanol, and the preferable mass ratio is 1-3:1-3:1-3. The invention also provides a carpomya vesuviana attracting device prepared from the attractant. The device can be used to attract males of carpomya vesuviana in forests and monitor and control populations of carpomya vesuviana, and has an important effect and meaning for forecasting and killing carpomya vesuviana.

Description

technical field [0001] The invention relates to the field of biological attractants, in particular to a fruit fly attractant. Background technique [0002] Jujube fruit fly Carpomya vesuviana Costa belongs to Diptera, Tephritidae Tephritidae, Tephritidae Subfamily Trypetinae, Fruit fly Trypetini, Carpomya Costa, and is an important obligate fruit-boring pest of Jujube plants. In 2007, for the first time in my country, Bactrocera jujube was found in three counties (cities) including Shanshan County, Toksun County, and Turpan City in the Turpan area of ​​Xinjiang. The occurrence area was 16,000 mu. 66,000 plants, which caused devastating damage to the jujube fruit industry in the region, and the fruit fly is still spreading in Xinjiang. Currently, hydrolyzed protein baits and fruit fly attractants are mainly used to monitor the insect. However, according to the response of front-line quarantine workers in my country, the above two methods are less effective in trapping Bacter...
