Effect test

example 1

[0029] Repellent: use linalool as the effective component, prepare a solution with a concentration of 100 μg effective component / 100 μl n-hexane, and use it as a repellent for female Chilo suppressalis. Linalool is a commercial reagent, and the product information is as follows: manufacturer: SIGMA-ALDRICH; product number: 78-70-6; purity ≥ 97%.

[0030] Repellent experiment: Use a pipette gun to draw 100 μl of the prepared solution as a repellant for female Chilo borer and inject it into a rubber stopper (pheromone lure of Beijing Zhongjie Sifang Biotechnology Co., Ltd., made of rubber, with an inner diameter of 7mm and a height of 1.3mm). cm), made into a repellent core, and then the rubber stopper was placed on the support between two rice plants, as a source of flavor, the support was 30cm high, one rubber stopper, 2 rice plants, and an average plant height of 55cm. The repellent effect of the odor source on the female adult Chilo borer after mating was verified by wind tu...

example 2

[0033] Repellent: use 2-heptanol as the effective component, and prepare a solution with a concentration of 100 μg effective component / 100 μl n-hexane, as a repellent for female Chilo suppressalis. 2-Heptanol is a commercial reagent, and the product information is as follows: manufacturer: SIGMA-ALDRICH; product number: 543-49-7; purity ≥ 97%.

[0034] Repellent experiment: Experimental conditions and experimental steps are the same as Example 1. 57 female Chilo borer moths were tested. According to statistics, the number of rice plants (flavor source) contacted within 10 minutes was 18.

example 3

[0036] Repellent: use D-limonene as the effective component, and prepare a solution with a concentration of 100 μg effective component / 100 μl n-hexane, as a repellent for female Chilo suppressalis. D-limonene is a commercial reagent, and the product information is as follows: manufacturer: SIGMA-ALDRICH; product number: 5989-27-5; purity ≥ 97%.

[0037] Repellent experiment: Experimental conditions and experimental steps are the same as Example 1. 56 female Chilo borer moths were tested. According to statistics, the number of rice plants (taste source) contacted within 10 minutes was 25.

Abstract

The invention provides application of Beta-myrcene as a female chilo suppressalis walker repellent component and a female chilo suppressalis walker repellent. Preferably, the repellent component is prepared from 10 parts by weight of beta-myrcene, 50 to 100 parts by weight of 2-heptanol, 2 to 8 parts by weight of alpha-cedrene, 5 to 15 parts by weight of caryophyllene and 2 to 8 parts by weight of2-nonanone. The application of beta-myrcene as a female chilo suppressalis walker repellent component and the female chilo suppressalis walker repellent which are provided by the invention provides anew approach to the environment-friendly and effective prevention and control of chilo suppressalis walker harming paddy rice, is of great significance in preventing and controlling chilo suppressalis walker harming paddy rice in China, and has broad economic, social and ecological benefits.

Description

technical field [0001] The invention relates to the use of β-myrcene as a component of a repellent for female Chilo borer and the repellent for female Chilo borer. Background technique [0002] Chilo suppressalis Walker (Chilo suppressalis Walker) is an important lepidopteran pest in paddy fields. It has an average of 2-3 generations per year in rice areas of China, but it may have up to 5 generations in southern rice areas. The first generation of Chilo borer generally occurs at the end of May or early June, and the second generation occurs at the end of July and early August. In the southern China rice region, almost every growth stage of rice is damaged by the stem borer, especially at the tillering and heading stages. Chilo borer damage can lead to "withered heart" and "white head" of rice plants. Every year, huge economic losses are caused by the damage of Chilo borer. Traditionally, the control of Chilo borer mainly relied on chemical pesticides. The extensive use ...
