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.

Description

technical field [0001] The invention relates to a pest control method, in particular to an attractant for controlling diamondback moth. Background technique [0002] Plutella xylostella belongs to the family Lepidoptera and is a worldwide vegetable pest. It seriously damages Brassica crops such as cabbage, cauliflower, kohlrabi, mustard greens, cabbage, radish, and rape. The crops planted in the field are often attacked by agricultural pests, resulting in crop failure and / or failure, causing major economic losses to farmers. The long-term use of chemical pesticides to control Plutella xylostella has caused serious "3R" problems, that is, severe pesticide residues, and the resistance of Plutella xylostella to chemical pesticides, leading to another rampant outbreak of Plutella xylostella. Not only that, chemical pesticides are continuously enriched in deep soil and cannot be decomposed, and pesticide residues can even be detected in water and air. To sum up, it is imperati...
