Method for preventing and killing Oides duporti

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.
