Problems solved by technology

For the traditional control method of star anise leaf beetle, it is considered to use conventional spraying of chemical pesticides to prevent and control. Most of the star anise trees are planted in the ft area, and the perennial star anise trees are tall, which requires pulling pipes and spray guns. The conventional control effect is not good, and it is easy to cause personnel poisoning
At the same time, most of the conventional control is "don't scatter eagles if you don't see rabbits". Farmers will not prevent and control the star anise leaf beetle if they don't find out the damage. Therefore, most of the control is concentrated in the outbreak period of the star anise leaf beetle.

Abstract

The invention discloses a method for preventing and killing Oides duporti. By virtue of circulating application of a medical fertilizer from November to December, the incubation rate of Oides duportiova and the pupation rate of Oides duporti pupae are decreased, and the population number of the Oides duporti in a field is decreased; and by virtue of a hot smog method in a full outbreak period from March to April and from July to August, pesticide smog with high concentration and high density is utilized for carrying out long-term enshrouding treatment, so that Oides duporti larvae and adult Oides duporti are difficult to hide, and 95% of prevention and treatment effects or above can be achieved through two treatment processes.
