Problems solved by technology

[0006] At the same time, the application of interfering mating technology has limited the application and development of this technology because of the high synthesis cost and relatively large dosage of the original drug of sex pheromone components.

Embodiment 1

[0030] Esters are sex pheromone components, and their aldehydes, alcohols, and ketone analogs have antagonistic effects; and it shows that different insect sex pheromone component analogs have different antagonistic responses to insect sex pheromones.

[0031] From August 25 to September 29, 2020, a comparative experiment was carried out in the pear orchard of Qianxian County, Shaanxi Province, to trap the small pear borer moth with sex pheromone lures and lures added with insect sex pheromone analogs.

[0032] Among them, the CK components of the sex pheromone lure core of pear borer worm are cis-8-dodecene acetate and trans-8-dodecene acetate; In order to interfere with the effect, cis-8-dodecene acetate and trans-8-dodecene acetate analogues were added to the lure. Among them, the added cis-8-dodecene acetate analogs are cis-8-dodecenal (referred to as group A) and cis-8-tetradecan-2-one (referred to as group B) ); The added trans-8-dodecenyl acetate analog is trans-8-dode...

Embodiment 2

[0038] Esters are sex pheromone components, and their aldehyde and ketone analogs have antagonistic effects; and it shows that different insect sex pheromone component analogs have different antagonistic responses to insect sex pheromones.

[0039] 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 (denoted as group A) and cis-9, trans-11-hexadecen-2-one (denoted as group B).

[0040] The original pheromone in the lure is 1mg, and the content of the added analogue is 0...

Embodiment 3

[0045] Alcohols are used as sex pheromone components, and their aldehydes and ester analogs have antagonistic effects, and it shows that different insect sex pheromone component analogs have different antagonistic responses to insect sex pheromones.

[0046] From July 9 to July 22, 2021, a comparative test of beet armyworm sex pheromone lures and insect sex pheromone analogs added to trap beet armyworms was carried out in the chive field in Xinghua, Jiangsu. Among them, the CK components of the sex pheromone lure of beet armyworm are cis-9, trans-12-tetradecenyl acetate and cis-9-tetradecenol. Since the previous two examples have verified the inhibitory effect of the analogues of the ester substance sex pheromones, this example aims at the inhibitory effect of the analogues when the alcohols are used as pheromones. Therefore, the analogue of cis-9-tetradecenol was selected, and cis-9-tetradecenal (referred to as group A) and cis-9-tetradecenyl acetate were added to the lure (...

Abstract

The invention discloses an application of an insect sex pheromone analogue in enabling insects to generate an antagonistic reaction on sex pheromone. In the prior art, the insect sex pheromone analogue corresponding to a certain substance is only a precursor, or needs to act together with other substances to form a pheromone attractant, and cannot be used independently; and after being combined with other substances, the compound does not aim at corresponding insects when the compound is used as analogues. Insects in different habitats in nature are different, and behavior rhythms of different insects are also different, so that the application of the sex pheromone analogue to the corresponding insects is a new discovery aiming at the original pests with a certain sex pheromone. According to the invention, the inhibition effect of the insect pheromone analogue on the attractive effect of the insect sex pheromone on male adults is found, and the possibility is provided for improving the pest trapping accuracy and reducing the prevention and control cost through the application of the insect pheromone analogue.

Description

technical field [0001] The invention relates to the application field of insect sex pheromones, in particular to the application of insect sex pheromone analogs in making insects produce antagonistic responses to sex pheromones. 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 reproduce offspring. At the same time, insect sex p...
