Attractant for diamondback moth

Abstract

The present invention discloses a diamondback moth attractant, which aims at providing an attractant with good attractive effect on male moth and female moth. The present invention contains diamondback moth sex pheromone, host-plant volatile substance and plant oil with the mass ratio of 1:800 to 8000:180; the host-plant volatile substance contains cis-3-vinyl alcohol acetate, cis-3- vinyl alcohol, trans-2-hexene aldehyde and allyl isothiocyanate with the volume ratio of 1:1:1:1; the diamondback moth sex pheromone is formed by mixing cis-11-hexadecane aldehyde, cis-11-hexadecane acetate and cis-11-hexadecane enol according to the mass ratio of 7:3:1. The optimal component of the diamondback moth attractant contains diamondback moth sex pheromone, host-plant volatile substance and plant oil with the mass ratio of 1:4000 to 8000:180. The attractant of the present invention can be used for insect condition prediction as well as mass trap and kill of diamondback moth.

Description

Technical field: [0001] The invention belongs to the field of biotechnology and relates to a diamondback moth attractant. Background technique: [0002] The diamondback moth (Plutella xylostella L.) belongs to the family Lepidoptera and is a worldwide pest that damages cruciferous vegetables. worldwide distribution. Serious damage to cruciferous vegetable plants such as cabbage and cauliflower. The global annual cost of prevention and treatment is about 1 billion US dollars. The extensive use of chemical pesticides has made it resistant to almost all pesticides used in the field, and it is difficult to control its harm by relying solely on chemical control. Therefore, it is particularly important to use insect pheromones to control diamondback moths. [0003] In my country, the application of pheromone interference technology to control pest damage is difficult to popularize and apply because it costs too much to use traditional pesticides, especially the income of agric...

Problems solved by technology

However, because conventional sex pheromone lures can only trap and kill male moths, and have no attracting effect on female adults, they are effective for single-mating insect species, but it is difficult to achieve impressive field application effects for multiple-mating insects such as diamondback moth. It is still difficult to replace chemical pesticides to a satisfactory degree. How to screen new and efficient attractants and improve the trapping effect of sex pheromone lures is still an important problem that we need to solve at present.
