Embodiment 1

[0018] Example 1 Screening the best formulation of sex attractant for Spodoptera moth

[0019] Add dropwise the n-hexane solution containing the moth attractant to the lure, wait for the n-hexane solution containing the moth attractant to volatilize, then add 100 μL of n-hexane dropwise to the lure, wait until the n-hexane After volatilization, the lure core containing the sex attractant of noctuid moth is prepared. Put the lure in the trap, and then place the trap in the field where the occurrence of Spodoptera is more serious. In order to ensure the release effect, add 150-1150 μg of Spodoptera moth attractant to each 1mL rubber lure, the average distance between the traps is 10m, the height of the lure core is set to 100cm from the ground, and the trap type is a box trap . In order to further illustrate the feasibility of the present embodiment, 12 specific formulas are provided in Table 1.

Embodiment 2

[0026] Example 2 The best trapper for the field screening of the sex attractant of Spodoptera moth

[0027] Adopt formula 6 in the embodiment 1 to prepare the lure core, select the vegetable field in Yanqing area that the number of Spodoptera moths is more, the area is more than 10 mu, the distance between the traps is about 10m, and the height of the traps is 100cm, place the above-mentioned traps at random respectively. Box-type traps, barrel-type traps, funnel-type traps, triangular-type traps, and sixteen-hole type Noctuidae general-purpose traps containing lure cores lacking noctuid moth sex attractants. Three replicates were set up for each treatment. In order to further illustrate the feasibility of this embodiment, five different trap types are given in Table 3.

Abstract

The invention discloses a sex attractant for Spodoptera moth and its application, which belong to the technical field of insect sex pheromone preparation. The sex attractant of the present invention comprises cis-11-hexadecene-1-alcohol and trans-7-dodecene acetate, and the masses of the two are 850 μg and 150 μg respectively, which is the optimal ratio. The trapping effect is the best when the lure core of the moth-lacking attractant is placed in a box-type trap for trapping. The sex moth attractant provided by the invention can effectively lure male moth moths, reduce the risk of harm to offspring, and has a strong trapping ability; it has strong species specificity, does not harm other beneficial species, and is environmentally friendly; it has good stability and a long-lasting effect Long, it can trap and kill noctuid moths for a long time, and control the population below the harmful level. The sex attractant of the present invention can be applied to the insect situation monitoring, mass trapping and interfering mating of Spodoptera moth, and is of great significance for green prevention and control of Spodoptera moth.

Description

technical field [0001] The invention relates to the technical field of preparation of insect sex pheromones, in particular to a sex attractant for Spodoptera moth and its application. Background technique [0002] Niphonix segregate belongs to Lepidoptera Noctuidae and is an important agricultural pest. In my country, it is mainly distributed in Heilongjiang, Hebei, Sichuan, Yunnan and other places. Spodoptera moth mainly feeds on larvae, and host plants include Moraceae Humulus and Cruciferous vegetables. Like other herbivorous Noctuidae insects, this insect has gluttony, and its larvae have a long period, strong viability, and large food intake. If an outbreak occurs, it will cause great damage to crops. Adults are nocturnal and have strong concealment and strong phototaxis. Traditionally, chemical control is mostly used, but the use of chemical pesticides often leads to problems such as drug resistance, environmental pollution, pesticide residues, and pest re-emergence...
