Embodiment 1

[0013] Mix the cabbage moth sex attractant with the solvent (n-hexane), add the mixed solution into the rubber head lure, after the solvent evaporates completely, place the lure in the barrel trap, and then place the trap In the plots where cabbage armyworm occurs more seriously. In order to ensure the release effect, put 100-1500 μg sex attractant of Brassica oleracea per 1 mL of rubber lure core, and the average distance between traps is more than 10m. In order to further illustrate the feasibility of the present embodiment, 10 specific formulas are provided in table 1:

[0014] Table 1

[0015]

[0016] Select a contiguous cabbage field with the same cabbage variety, growth, fertilizer and water management conditions, an area of ​​more than 10 mu, and serious occurrence of cabbage armyworm as the experimental field. Set up 5 replicates for each treatment, and place the above-mentioned sexual attractant buckets evenly and randomly. At the same time, 5 light traps, blank...

Abstract

The invention discloses a mamestra brassicae linnaeus sex attractant, which is prepared from cis-11-hexadecenyl acetate, cis-11-heptadecyl acetate and hexadecyl acetic ester. The invention also provides an application method of the mamestra brassicae linnaeus sex attractant. The sex attractant provided by the invention has the advantages that the preparation is simple; the raw materials can be easily obtained; strong attractant capability is realized; the stability is high; the lasting period is long; the specifity is high; the mamestra brassicae linnaeus cannot easily generate resistance; no harm is caused on people and livestock; the environment-friendly effect is achieved; the stress resistance is high; the use is convenient. The mamestra brassicae linnaeus sex attractant can be accurately applied to pest detection and forecasting, mating interference and mass trapping, and has the important significance on the comprehensive control of themamestra brassicae linnaeus.

Description

technical field [0001] The invention belongs to the technical field of insect sex pheromone preparation, and in particular relates to a sex attractant for cabbage armyworm and its preparation method and application. Background technique [0002] Cabbage moth (Mamestra brassicae Linnaeus) belongs to Lepidoptera Noctuidae and is a major vegetable pest with a wide distribution range. It mainly harms the leaves of crops with larvae, eats the leaves, pollutes the leaf balls, and brings huge economic losses to agricultural production in severe cases. Spodoptera cabbage has strong fecundity, and the chemical agents known to have good control effects on it are mostly organochlorine pesticides that are banned from production, and Spodoptera cabbage has developed resistance to many chemical agents to varying degrees. Long-term use of chemical agents to control cabbage armyworm may pollute the environment, destroy natural enemies and ecosystems, and the control effect is unstable. Ac...
