Embodiment 1

[0013] Embodiment 1 Preparation of sex attractant for small cutworm

[0014] Add the n-hexane solution containing the synergist dropwise on the lure containing the sex pheromone of the cutworm, after the n-hexane volatilizes, add dichloromethane dropwise on the lure, and after the dichloromethane volatilizes, the product containing The lure of the small cutworm sexual attractant, the lure core is placed in the barrel trap, and then the trap is placed on the land where the small cutworm occurs more seriously. In order to ensure the release effect, 100-1000 μg of small cutworm sex attractant was placed in every 1 mL of rubber lure core, and the average distance between traps was 10 m. In order to further illustrate the feasibility of the present embodiment, 18 specific formulas are provided in table 1:

Embodiment 2

[0018] Embodiment 2 Trapping experiment

[0019] Select the contiguous cabbage field with the same cabbage variety, growing state, and fertilizer and water management conditions, with an area of ​​more than 10 mu, and a relatively serious occurrence of small cutworms as the experimental field, and set up 5 repetitions for each treatment, and place the above-mentioned sexually induced cutworms containing small cutworms evenly and randomly. At the same time, 5 light traps, 5 blank barrel traps and 5 barrel traps containing three live female cutworms that had not yet mated for 3 days were placed randomly. The average spacing between traps is 10m. After placement, the number of trapped cutworms was investigated every three days, and the live female cutworms that had emerged were replaced, and the trapping positions were randomly changed, and the investigation continued for 30 days. The trapping effect is shown in Table 2:

Abstract

The invention discloses an attractant composition for preventing and controlling agrotis ypsilon. The attractant composition is prepared from an agrotis ypsilon sex pheromone component and a synergist, wherein the agrotis ypsilon sex pheromone component is one or more of cis-7-dodecenyl acetate, cis-9-tetradecenyl acetate and cis-11-hexadecenyl acetate; the synergist comprises one or more of cis-7-dodecenyl-1-ol propionate, cis-11-hexadecenyl-1-ol-methanesulfonate and cis-8,cis-10-dodecenyl dienyl methyl ketone. The attractant composition disclosed by the invention has the advantages of small dosage and environment friendliness, and also can be accurately applied to insect condition prediction, mass trapping and mating disruption; the effect of comprehensively managing the agrotis ypsilon is remarkably improved; the attractant composition disclosed by the invention has important meaning on comprehensive management of the agrotis ypsilon.

Description

technical field [0001] The invention belongs to the technical field of insect sex pheromone preparation, and in particular relates to an attractant composition for preventing and controlling cutworms. Background technique [0002] Agrotis ypsilon (Rottemberg), belonging to Lepidoptera and Noctuidae, is a worldwide polyphagous agricultural pest and one of the main underground pests in my country. It is mainly harmful to various crops, such as cruciferous, leguminous, solanaceous, cucurbitaceous and other vegetables, as well as more than 100 crops such as peanuts and tobacco. At the same time, it is also an important pest in orchards and lawns. At present, the methods of its control mainly include spraying chemical agents and trapping and killing adults. It is well known that chemical agents have the advantages of quick effect and convenient use, but their drug resistance is becoming more and more serious. For example, the small cutworm has developed high resistance to variou...
