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, cis 9-tetradecen-1-ol in redistilled n-hexane In alkanes, the concentration was 10 μg / uL; thus, cis-9 and trans-11-tetradecadiene acetate solutions with a concentration of 10 μg / μL were obtained respectively, and the concentrations were 10 μg / μL for cis-9 and trans-12-decadiene. Tetradecadiene acetate solution with a concentration of 10 μg / μL cis-9-tetradecen-1-ol solution.

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

[0036] With the cis-9 of above-mentioned concentration, anti-12-tetradecadienyl acetate solution, cis-9-tetradecen-1-alcohol solution are mixed with the volume ratio of 9:1, and the total concentration of preparation sex pheromone is A 10 μg...

Embodiment 2

[0046] Embodiment 2, wind tunnel behavior measurement

[0047] Wind tunnel installation:

[0048] The wind-pushing wind tunnel device consists of two parts: the wind source and the wind tunnel chamber. The wind source is provided by a manual gear fan at a constant speed, and the exterior is covered with black fine gauze to avoid visual interference; the wind tunnel chamber is composed of a transparent cylinder with a bottom diameter of 50cm and a length of 180cm, and is covered with fine iron sand mesh on both sides. The wind tunnel device is placed at a temperature of 27±2°C and a humidity of 70-80%, with a weak light source provided by a 5lux red light. The heights of the insect releaser and the odor source are both 25cm away from the lower surface and 30cm away from the downwind and upwind respectively. The insect releaser was a transparent glass tube with openings at both ends, and the odor source was covered with 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 sex pheromone directional disruptor of diamondback moth. Background technique [0002] Plutella xylostella is an oligophagous pest that feeds on cruciferous vegetables. It is seriously harmful and widely distributed around the world. Plutella xylostella has strong fecundity, serious overlapping of generations, and resistance to almost all insecticides to varying degrees. It is increasingly difficult to control the population of Plutella xylostella simply by using chemical pesticides; at the same time, the unreasonable use of chemical pesticides will also bring certain environmental problems. Female moths of diamondback moth during courtship release a mixture of cis-11-hexadecenyl acetate, cis-11-hexadecen-1-al and cis-11-hexadecen-1-ol as sex pheromones The males mate. In pest control, sex pheromones can be used to trap a large number of male moths, making the rat...
