Problems solved by technology

[0003] Attractants have the advantages of strong specificity, high efficiency, and no pollution. They have developed rapidly in recent years. However, due to the high cost of sex attractants and the fact that they can only trap male adults, it is difficult for insects that have mated many times. Satisfactory moth trapping effect in the field cannot be obtained yet

Embodiment Construction

[0012] The sex pheromones of beet armyworm implemented in this experiment are (Z, E)-9,12-tetradecadiene acetate, (Z)-9-tetradecenol, and the plant volatiles are phenylacetaldehyde, green Leaf alcohol, trans-2-hexenal and cis-3-hexenal acetate. The trapping experiment was carried out according to the scheme designed in Table 1.

[0013] The carrier is a self-developed compatible pheromone and slow-release material of plant volatiles, the antioxidant is butyl hydroxyanisole, and the ultraviolet light adsorbent is 2-hydroxy-4-methoxybenzophenone.

[0014] The vegetable type in the field is a cabbage field, and the trap is a cylindrical trap. Set up three replicates.

[0015] As shown in Table 1, the attractant of the present invention to the male adults of Plutella xylostella is obviously higher than that of using sex pheromone alone, and it also has a certain attracting effect on the females of the beet armyworm. Formula 6 has nearly doubled the trapping amount of beet armyw...

Abstract

The invention discloses a beet armyworm dual-sexual attractant which comprises a beet armyworm sex pheromone and a host plant volatile matter according to the mass percent of 1:900 to 100:1. Compared with the traditional attractant, the attractant provided by the invention has the advantages that the attraction rate of beet armyworms is improved and female armyworms are attracted. Therefore, the attractant provided by the invention can be used for observing and predicting the armyworm situations, and trapping and killing the beet armyworms in beet farms.

Description

technical field [0001] The invention belongs to the field of biological control, and in particular relates to a bisexual attractant for beet armyworm. Background technique [0002] Beet armyworm ( Spodoptera exigua Hubner) is a polyphagous agricultural pest with intermittent outbreaks. In recent years, with the change of agricultural cultivation system in my country, the adjustment of crop variety layout, warming temperature and the emergence of chemical pesticide resistance, etc., the control of beet armyworm is difficult. It is getting bigger and bigger, and has risen from a minor pest to an important pest that harms crops such as vegetables, cotton and flowers, and the damage is increasingly serious all over the country. [0003] Attractants have the advantages of strong specificity, high efficiency, and no pollution. They have developed rapidly in recent years. However, due to the high cost of using sex attractants and the fact that they can only trap male adults, it is...
