AI Technical Summary

Technical Problem

Among existing aphid control methods, aphid resistance is rapidly increasing, the use of traditional insecticides leads to environmental pollution, and the aphid alarm pheromone EBF is unstable under field conditions, making it difficult to apply effectively.

Method used

By using a combination of alarm pheromone analogues, including 2,6,10-trimethyl-1,5,9-undecanetriene and 12.5% ​​CAU1204 microemulsion, and applying them at staggered times along with the plant-derived pesticide 0.3% matrine aqueous solution, the incidence of aphid alarm behavior was increased, and the pesticide control effect was enhanced.

Benefits of technology

It significantly increases the incidence of aphid alarm behavior, achieves a control effect of 98.7%, has a long duration, reduces pesticide usage, and minimizes environmental pollution.

Abstract

This invention belongs to the field of pest control technology, specifically relating to an alarm pheromone analog combination, a method for controlling aphids, and its application. This invention provides an alarm pheromone analog combination comprising: 2,6,10-trimethyl-1,5,9-undecanetriene and 12.5% ​​CAU1204 microemulsion. Both 2,6,10-trimethyl-1,5,9-undecanetriene and 12.5% ​​CAU1204 microemulsion are alarm pheromone analogs, structurally stable, low-cost, safe, and environmentally friendly, and can significantly increase the incidence of aphid alarm behavior. This invention provides a method for controlling aphids by combining the alarm pheromone analog combination with plant-derived pesticides at staggered times. First, spray the aphid alarm pheromone analog combination, then after an interval of 30-60 minutes, spray a 0.3% matrine aqueous solution. This method demonstrates significant aphid control and has a particularly long-lasting effect.
