Abstract

The invention relates to an attractant for adult Cnaphalocrocis medinalis and application of the attractant, and belongs to the technical field of an information compound for attracting a large amount of pests. The attractant for adult Cnaphalocrocis medinalis provided by the invention comprises a sex pheromone, wherein the sex pheromone comprises cis-13-octadecenal, cis-11-octadecenal, and cis-13-octadecenol according to a mass ratio of 100 to (5 to 20) to (5 to 20). Compared with an attractant formed by cis-11-octadecenal, cis-13-octadecenal, cis-11-octadecenol and cis-13-octadecenol, the attractant for adult Cnaphalocrocis medinalis provided by the invention has better attracting effect, the attracting capacity of the Cnaphalocrocis medinalis sex attractant can be significantly improved, and the attracting amount is 2.6 to 4.5 times higher than that of the attractant formed by four sex pheromones.

Description

technical field [0001] The invention belongs to the technical field of trapping pests in large quantities with semiochemicals, and in particular relates to an attractant for adult rice leaf rollers and an application thereof.
