Embodiment 1

[0028] Example 1 Insect pheromone components cis-9, trans-12-tetradecenyl acetate analogues cis-9, trans-12-tetradecenal or cis-9, trans-11-hexadecene Inhibitory test of en-2-one on Spodoptera litura lures lure Spodoptera litura

[0029] From October 19 to November 10, 2020, a comparative experiment was carried out on Spodoptera litura sex pheromone lures and lures added with insect sex pheromone analogs to trap Spodoptera litura in Kunde Farm, Quanzhou, Fujian. Among them, the CK components of the sex pheromone lure of Spodoptera litura are cis-9, trans-11-tetradecyl acetate and cis-9, trans-12-tetradecyl acetate; In the analogs of sex pheromones, ketones interfere with sex pheromones. The analogs of cis-9 and trans-12-tetradecenyl ester are specially selected, and cis-9, trans-12-tetradecenal (panel A) and cis-9, trans-11-hexadecen-2-one (panel B).

[0030] The original pheromone in each lure is 1 mg, and the contents of cis-9, trans-12-tetradecenal and cis-9, trans-11-hex...

Embodiment 2

[0035] Example 2 Insect pheromone components cis-9, trans-12-tetradecenyl acetate analog cis-9, trans-12-tetradecenal or cis-9, trans-11-hexadecene Inhibitory Test of En-2-ones on Beet Spodoptera Lures Attracted by Beet Spodoptera

[0036]From September 18 to October 13, 2021, a comparative test of beet armyworm sex pheromone lures and insect sex pheromone analogs added to trap beet armyworms was carried out in Dafeng District, Yancheng City, Jiangsu Province. Among them, the CK components of the sex pheromone lure of beet armyworm are cis-9, trans-12-tetradecenyl acetate and cis-9-tetradecenol. Added cis-9, trans-12-tetradecenal A and cis-9, trans-11-hexadecen-2-one B in the lure respectively.

[0037] The original pheromone in each lure is 1mg, and the contents of the added analogues are 0.05mg, 0.5mg and 1mg respectively. In each treatment, the content of analogues was recorded as 1, 2, and 3 from low to high, respectively. Set up 3 lures per mu, and each lure is spaced ...

Embodiment 3

[0042] Example 3 Insect pheromone components cis-9, trans-12-tetradecenyl acetate analog cis-9, trans-12-tetradecenal or cis-9, trans-11-hexadecene Inhibitory Test of En-2-ones on Indian Meal Moth Attractant Attracted by Indian Meal Moth

[0043] From July 1 to July 15, 2021, a comparative test of Indian meal moth sex pheromone in the rice moth trap and a trap added with insect sex pheromone analogs was carried out in Yuhuan Grain Depot, Zhejiang Province to trap Indian meal moth. Among them, the sex pheromone CK components of Indian meal moth are cis-9, trans-12-tetradecenyl acetate and cis-9, trans-12-tetradecenol. cis-9, trans-12-tetradecenal A and cis-9, trans-11-hexadecen-2-one B were added to the traps, respectively.

[0044] The original pheromone in each lure is 1mg, and the contents of the added analogues are 0.05mg, 0.5mg and 1mg respectively. In each treatment, the content of analogues was recorded as 1, 2, and 3 from low to high, respectively. Set up 3 lures per...

Abstract

The invention discloses an application of a cis-9, trans-12-tetradecene acetate analogue, and the cis-9, trans-12-tetradecene acetate analogue is used as a substance for enabling insects to generate an antagonistic reaction on sex pheromone. The cis-9, trans-12-tetradecene acetate analogue is cis-9, trans-12-tetradecene aldehyde or cis-9, trans-11-hexadecene-2-one. According to the invention, the inhibition effect of the insect sex pheromone analogue cis-9, trans-12-tetradecenal or cis-9, trans-11-hexadecen-2-one on the sex pheromone cis-9, trans-12-tetradecene acetate of the insect on the attractive effect of male adults is discovered, and the cis-9, trans-12-tetradecene acetate analogue is applied to improve the pest trapping accuracy and improve the prevention and control effect.

Description

technical field [0001] The present invention relates to the technical field of insect sex pheromones, more specifically to a kind of insect sex pheromone component cis-9, trans-12-tetradecyl acetate analogues in making insects antagonize sex pheromones React application. Background technique [0002] Pheromone is a general term for trace chemical substances that play a role in chemical communication between organisms. It is a compound used by insects to express various information such as gathering, foraging, mating, and alerting. It is a chemical molecular language for insects to communicate. For example, in nature, after sexual maturity, female adult pests release a compound called sex pheromone, which is released into the air and spreads with the airflow, stimulating the chemical sensory organs in the antennae of male insects, and causing male individual sex drive And lure the male insects to fly to the release source, and mate with the released female adults to reproduc...
