Embodiment 1

[0031] This embodiment discloses a composition for attracting tea seed weevil adults and a preparation method thereof, and the specific steps are as follows:

[0032] A, preparation of organic mixture;

[0033] Mix honeysuckle essential oil, Andrographis paniculata essential oil, cis-3-hexen-1-ol, cis-3-hexenyl acetate, 3-heptanone, hexanal and nonanal according to the volume ratio recorded in Table 1;

[0034] B, dissolving gelatin and gum arabic to prepare encapsulation solution;

[0035] Weigh the gum arabic and gelatin shown in Table 1, add deionized water to make the glue solution with the required concentration, and adjust the pH to 8 with 20% sodium peroxide solution.

[0036] Dissolve gelatin and gum arabic in water respectively, adjust the pH value of the aqueous solution of gelatin and gum arabic to obtain a wrapping solution; wherein the consumption of gelatin, gum arabic and water in the wrapping solution is shown in Table 1; the pH value of the wrapping solution ...

Abstract

The invention discloses a composition for attracting adult curculio chinensis. The composition comprises the following components in parts by volume: honeysuckle essential oil, andrographis essentialoil, cis-3-hexen-1-ol, cis-3-hexenyl acetate, 3-heptanone, hexanal and nonanal. The preparation method of the composition comprises the following steps: A, preparing an organic matter mixed solution;B, dissolving gelatin and gum arabic to prepare a coating solution; C, adding the coating solution into the organic matter mixed solution under the stirring condition, and uniformly mixing; D, coagulating and solidifying to prepare a slow-release composition; and under the stirring condition, adding acetic acid into the mixed solution prepared in the step C to adjust the pH value of the mixed solution to be 3.8-4, and coagulating the mixed solution to prepare a composition with a slow release effect. The adult curculio chinensis is attracted pertinently, and the damage of the curculio chinensis in an oil tea garden can be effectively prevented and controlled in cooperation with the corresponding insect catcher. Meanwhile, organic solvents and chemical pesticides are not used, and the negative influence on the ecology and the environment of the oil tea garden is small.

Description

technical field [0001] The invention relates to the field of tea seed weevil prevention and control, in particular to a composition for attracting tea seed weevil adults and a preparation method thereof. Background technique [0002] Teaseed weevil [TeaseedweeviI] is a tea tree pest, scientific name: Curculiochinensis Chevrolat, also known as camellia weevil or camellia weevil, through adults to supplement nutrition, lay eggs and larvae to eat seeds in the fruit to cause harm, causing camellia and tea seeds Trees drop fruit. At the same time, after the larvae are infested, the tea fruit will be filled with powdery or stick-shaped feces, and the seed kernels are prone to mold and deterioration, which has a significant impact on the quality of camellia oil. At present, almost all fruiting tea trees or tea seed trees are harmed by the tea seed weevil, and the fruit drop rate caused by it reaches more than 20%. Occurrence law: Tea seed weevil has one generation every two years...
