Chilo suppressalis male insect trapping agent and preparation method thereof

Abstract

The invention discloses a chilo suppressalis trapping agent and a preparation method thereof. The chilo suppressalis trapping agent is prepared from, by weight, 10-15 parts of synergist, 50-70 parts of sex pheromone and 600-900 parts of a solvent; the synergist is a combination of beta- caryophyllene, 4'-Methylacetophenone and n-nonane; the sex pheromone is a combination of cis-11-hexedecanal, cis-13-octadecenal and cis-9-hexedecanal. Through combination of the synergist and the sex pheromone, the trapping amount of chilo suppressalis male insects can be greatly increased, and the release timeof the synergist can be prolonged. The synergist is beta-caryophyllene, 4'-Methylacetophenone and n-nonane, but for a single-component synergist, the combined synergist can enhance the trapping effect on chilo suppressalis. The optimized chilo suppressalis sex pheromone composite synergist can trap a large number of chilo suppressalis adults in the field. The technology is simple and convenient to operate, and can be applied to chilo suppressalis prediction and green prevention and control.

Description

Technical field

[0001] The invention belongs to the field of biological pesticide preparations, and in particular relates to a chilo suppressalis male insect trap and a preparation method thereof.Background technique

[0002] Chilosuppressalis (walker) is an important pest in rice production in my country. At present, chemical pesticides are mainly used to control Chilosuppressalis (walker). However, because the insect is a larval borer damage and its development is irregular, the control effect of chemical pesticides is often poor; In addition, chemical pesticides can accumulate in the soil for a long time, which may cause adverse effects on the ecological environment and human health.

[0003] Compared with conventional chemical pesticide control, sex attractant cluster traps use special traps to attract and kill target insect males, thereby reducing the probability of male and female mating, reducing the population of next generations, and minimizing the use of chemical pesticides. So as t...

Examples

Embodiment 1

[0014]The synergist is composed of β-caryophyllene, p-methylacetophenone, and n-nonane with a mass ratio of 1:1:1; the sex pheromone is composed of cis-11-hexadecane with a mass ratio of 48:6:5 It is composed of enal, cis-13-octadecenal and cis-9-hexadecenal; solvent is n-hexane.

[0015]According to the mass parts ratio, 15 parts of synergist, 59 parts of sex pheromone and 660 parts of solvent are mixed, and after mixing uniformly, the trapping agent is obtained. Place it in a polyamide tube and seal it with polyethylene material. Polyamide tube + sealed polyethylene material constitutes the release device, which can realize the slow and uniform release of the trapping agent.

Embodiment 2

[0033]The synergist is composed of β-caryophyllene, p-methylacetophenone, and n-nonane with a mass ratio of 1:0.1:0.1; the sex pheromone is composed of cis-11-hexadecane with a mass ratio of 48:6:5 It is composed of enal, cis-13-octadecenal and cis-9-hexadecenal; solvent is n-hexane.

[0034]According to the mass parts ratio, 12 parts of synergist, 59 parts of sex pheromone and 740 parts of solvent are mixed, and after mixing uniformly, the trapping agent is obtained. Place it in a polyamide tube and seal it with polyethylene material. Polyamide tube + sealed polyethylene material constitutes the release device, which can realize the slow and uniform release of the trapping agent.

Embodiment 3

[0036]The synergist is composed of β-caryophyllene, p-methylacetophenone, and n-nonane with a mass ratio of 1:0.1:1; the sex pheromone is composed of cis-11-hexadecane with a mass ratio of 48:6:5 It is composed of enal, cis-13-octadecenal and cis-9-hexadecenal; solvent is n-hexane.

[0037]According to the mass parts ratio, 11 parts of synergist, 59 parts of sex pheromone and 770 parts of solvent are mixed, and after mixing uniformly, the trapping agent is obtained. Place it in a polyamide tube and seal it with polyethylene material. Polyamide tube + sealed polyethylene material constitutes the release device, which can realize the slow and uniform release of the trapping agent.

[0038]The release devices containing trapping agents in Examples 2 and 3 were used as traps and placed in dry traps. The height of the traps was equal to that of the rice leaves, and the distance between each trap was 25 meters. The traps were arranged in random blocks and placed on the ridge. After 30 days Chec...
