Problems solved by technology

[0004] Beet armyworm and Spodoptera litura are both harmful to cruciferous vegetables, and the main components of their sex pheromones are cis-9, trans 11-tetradecadiene acetate, cis-9, trans 12-tetradecyl Diene acetate and cis-9, trans-12-tetradecadiene acetate, cis-9-tetradecen-1-ol; using the main components of the above-mentioned sex pheromones to trap target armyworms in the field has achieved good results. effect, but its effect on sex pheromone communication in diamondback moth is currently unknown

Embodiment 1

[0034] Dissolve cis-9, trans-11-tetradecadiene acetate, cis-9, trans-12-tetradecadiene acetate and cis-9-tetradecen-1-ol in redistilled n-hexane, respectively. In alkane, the concentrations were 10 μg / uL; thus, cis-9 and trans-11-tetradecadiene acetate solutions with a concentration of 10 μg / μL were obtained, respectively, with a concentration of 10 μg / μL cis-9, trans-12-deca Tetracarbadiene acetate solution with a concentration of 10 μg / μL cis-9-tetradecen-1-ol solution.

[0035] The above cis-9, trans-11-tetradecadiene acetate solution and cis-9, trans-12-tetradecadiene acetate solution are mixed in a volume ratio of 9:1 to prepare the total concentration of sex pheromones 10μg / μL solution of two-component sex pheromone of Spodoptera litura;

[0036] The above concentrations of cis-9, trans-12-tetradecadiene acetate solution and cis-9-tetradecene-1-ol solution are mixed in a volume ratio of 9:1, and the total concentration of sex pheromones is prepared as 10 μg / μL solution...

Embodiment 2

[0046] Example 2. Measurement of wind tunnel behavior

[0047] Wind Tunnel Installation:

[0048] The push-air wind tunnel device consists of two parts: the wind source and the wind tunnel. The wind source is provided by a manual constant-speed fan, and the outside is covered with a black fine gauze mesh to avoid visual interference; the wind tunnel is composed of a transparent cylinder with a bottom surface diameter of 50cm and a length of 180cm, and the two sides are covered with fine iron sand mesh. The wind tunnel device was placed at a temperature of 27±2°C, with a humidity of 70-80%, and a weak light source was provided by a 5lux red light. Both the insect dispenser and the odor source were located 25 cm from the lower surface at a height and 30 cm from the down and up air vents, respectively. The insect releaser is a transparent glass tube with two open ends, and the odor source is shielded by a gray iron cage to avoid errors caused by visual factors.

Abstract

The invention discloses a plutella xylostella sex pheromone directional disruptor. The directional disruptor is one of the following ingredients: cis-9, trans11-tetradecenoic acetate, cis-9, trans12-tetradecenoic acetate, wherein cis-9, trans11-tetradecenoic acetate and cis-9, trans12-tetradecenoic acetate are mixed in a weight ratio of (12-7): 1; cis-9, trans12- tetradecenoic acetate and cis9- tetradecene-1-alcohol are mixed in a weight ratio of (12-7): 1. The plutella xylostella sex pheromone directional disruptor has advantages of high efficiency, multiple ecological effects, simplicity in preparation, environmental friendliness, safety for mammal and the like, the encountering probability and mating times of male moth and female moth in field can be reduced, and the harm of the plutella on the crucifer can be alleviated.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to a novel directional interference agent of the sex pheromone of the diamondback moth. Background technique [0002] The diamondback moth is an oligophagous pest that feeds on cruciferous vegetables, causing serious damage and widespread worldwide distribution. Plutella xylostella has strong fecundity and serious overlapping of generations, and has developed different degrees of resistance to almost all insecticides. It is increasingly difficult to control the population of diamondback moth by simply using chemical pesticides; at the same time, the unreasonable use of chemical pesticides will also bring certain environmental problems. A mixture of cis-11-hexadecene acetate, cis-11-hexadecen-1-al and cis-11-hexadecen-1-ol released by female moths during courtship of diamondback moth as sex pheromone attraction Males mate. In pest control, sex pheromone can be used to trap a ...
