Plutella xylostella attractant

Abstract

The invention relates to a plutella xylostella attractant. The attractant comprises the following components in weigh percent: 10-80 of trans-2-hexenal, 1-50 of n-hexaldehyde, 1-80 of isothiocyanate / isosulfocyanate, 1-50 of leaf alcohol / cis-3-hexenyl, and 5-70 of phenylacetaldehyde. According to the plutella xylostella attractant disclosed by the invention, a certain proportion of plutella xylostella attractant is optimized, the attractant not only has relatively strong attraction ability to female adult plutella xylostella, but also greatly prolongs the field persistent effect time, and increases the total quantity of attracted adult plutella xylostella in multiples; and meanwhile, the attractant has good compatibility, the male plutella xylostella and the female plutella xylostella can be effectively attracted synchronously by adding male attractants such as known plutella xylostella sex pheromone, and the adult plutella xylostella can be attracted and killed in combination with the insecticide or a trap, and thus the aims of reducing field plutella xylostella population quantity and reducing the crop loss are achieved.
