The invention provides a method for luring Chrysopa sinica Tjeder to
restrict Toxoptera aurantii Boyer by synomone from tea shoots and
aphid sex pheromones. According to the invention, the synomone from tea shoots and the
aphid sex pheromones are taken as basic components to prepare a Chrysopa sinica Tjeder
trapping agent, which is used to lure the Chrysopa sinica Tjeder to trap an important injurious
insect, Toxoptera aurantii Boyer, of the buds and leaves of tea trees, and used chemical pesticides can be reduced and even avoided so as to alleviate the
pollution. The Chrysopa sinica Tjeder is the dominant species natural enemy of the Toxoptera aurantii Boyer, and by using the
trapping agent to lure and guide the Chrysopa sinica Tjeder to
restrict the Toxoptera aurantii Boyer, the
predation efficiency can be improved, and the
potency can be protected and utilized. The method provided by the invention protects the
biodiversity, uses the
pheromone substances to lure the important natural enemy, Chrysopa sinica Tjeder, to trap the Toxoptera aurantii Boyer effectively in a
tea garden, protects and utilizes the natural enemy resources, and is simple and convenient to implement and low in cost.
