Abstract:

Alarm pheromone is an important pheromone in the red imported fire ant (Solenopsis invicta Buren). It can arouse a variety of behavioral response such as attracting, avoiding and recruitment. In the present study, the red imported fire ant was used as the research object. The alarm pheromone of the red imported fire ant was synthesized through the Wolff-kishner-Huangminlon reduction method by one step, and its structure was identified and analyzed by gas chromatography-mass spectrometry (GC-MS) and standard products. The results showed that the purity of the synthesized compound purity was 90.2%, the synthesis method was reasonable, simple and efficient, the reaction conditions were controllable, there was no hidden safety hazard, and it was suitable for industrial production and application. The electroantennogram (EAG) experiment showed that the synthetic alarm pheromone can cause strong behavioral responses of the red imported fire ant workers, and the EAG response was significantly higher than that of the standard product at a dose of 100 μg (P<0.05).

Key words: red imported fire ant, Wolff-Kishner-HuangMinlon reaction, alarm pheromone, synthesis
