Embodiment 1

[0014] Example 1 Preparation of Sex Attractant for Potato Tuber Moth

[0015] Determine the specific amount of each component of the potato tuber moth sex attractant according to the weight percentage range of the following components: trans-4, cis-7-tridecadien-1-alcohol acetic acid and trans-4, cis-7-deca The ratio of tricarbatrien-1-ol acetate is 1:4; hexadecanoic acid is added to the sex pheromone of the potato tuber moth at a ratio of 0.01%-10%, and 1 mL of n-hexane is used to mix the sex attractant of the potato tuber moth with The solvent (n-hexane) is mixed, and the mixed solution is added to the butyl rubber head lure. After the solvent volatilizes completely, the lure is placed in a triangular trap, and then the trap is placed on the potato tuber moth. Serious plots. In order to ensure the release effect, put 100-1000 μg of potato tuber moth sex attractant into every 1mL of rubber lure core, and the average distance between traps should be more than 15m. In order t...

Embodiment 2

[0024] Example 2 Persistence period of sex attractant for potato tuber moth

[0025] Continue to investigate 5 repetitions of optimal formula 6 and sex pheromone in Example 1, the investigation method is consistent with Example 1, and continue to investigate. Experimental results such as figure 1 As shown, the test results show that except on rainy days (May 23 and June 5), the system-optimized sex attractant of potato tuber moth can continuously trap male potato tuber moths within 75 days, and it can attract male moths within 60 days. The moth effect can be played stably.

[0026] It can be seen that the system-optimized sexual attractant for potato tuber moth provided by the present invention can be accurately applied to mass trapping of potato tuber moth, interference with mating, and insect situation forecasting, and is of great significance for green management of potato tuber moth.

Abstract

The invention discloses a systematically-optimized phthorimaea operculella sex attractant and application thereof, and belongs to the technical field of insect sex pheromone preparation. The phthorimaea operculella sex attractant comprises a phthorimaea operculella sex pheromone and a female phthorimaea operculella gland extract, wherein the phthorimaea operculella sex pheromone is (Z,E)-trideca-4,7-dien-1-yl acetate and trans-4,cis-7,cis-10-tridecatrien-1-ol acetate, and the ratio of the (Z,E)-trideca-4,7-dien-1-yl acetate to the trans-4,cis-7,cis-10-tridecatrien-1-alcohol acetate is 1:4. Thefemale phthorimaea operculella gland extract is hexadecanoic acid, and added into the phthorimaea operculella sex pheromone according to the ratio of 0.01-10%. The phthorimaea operculella sex attractant can effectively attract male phthorimaea operculella, the phthorimaea operculella attracting amount of the phthorimaea operculella sex attractant which is added according to the ratio of 10% is increased by 58% than that of a pure sex pheromone, the lasting period can be prolonged to 60 days, thus the meeting probability of the female and male phthorimaea operculella can be lowered for a longterm, mating is disturbed, the breeding rate is lowered, pest populations are controlled step by step, and thus the purpose of preventing and controlling pests is achieved.

Description

technical field [0001] The invention belongs to the technical field of insect sex pheromone preparation, and in particular relates to a system-optimized potato tuber moth sex attractant and its application. Background technique [0002] The potato tuber moth, also known as the tobacco leaf miner [Phthorimaea operculella Zeller (Lepidoptera: Gelechiidae)], has been distributed in Asia, Europe, North America, Africa as its main host potato is native to the northern regions of Central and South America. It is a worldwide agricultural pest that harms Solanaceae crops in more than 100 countries, especially potatoes. Damage to potato leaves usually does not seriously affect yield, but damage to tubers can significantly reduce yield, especially if damage can reach 100% without cold storage. At present, the pest is distributed in more than 20 provinces and regions in my country, such as Yunnan, Guizhou, Sichuan, Guangdong, Guangxi, Hunan, Jiangxi and Gansu. With the increase of pot...
