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.

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

[0027] Adopt the formula 6 in the embodiment 1 to prepare the lure core, select the vegetable field in Yanqing area that the number of Spodoptera moth 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 prodenia litura sex attractant and application thereof, and belongs to the technical field of insect sex pheromone preparation. The prodenia litura sex attractant comprises cis-11-hexadecene-1-alcohol and trans-7-dodecene acetate, and the optimal mass ratio of the cis-11-hexadecene-1-alcohol to the trans-7-dodecene acetate is 850 micrograms and 150 micrograms respectively. The lure of the prodenia litura sex attractant is placed in a box-type trap to trap prodenia litura, and the trapping effect of the prodenia litura sex attractant is optimal. The prodenia litura sexattractant provided by the invention can effectively attract prodenia litura male insects, reduces the harm probability of offspring, has strong trapping capacity, the prodenia litura sex attractanthas high species specificity, does not not damage other beneficial species and is environmentally friendly; the prodenia litura sex attractant is good in stability and long in lasting period, and cantrap and kill the prodenia litura for a long time, so that the population quantity of the prodenia litura can be controlled to be below the hazard level. The sex attractant disclosed by the inventioncan be applied to insect condition monitoring, mass trapping and mating interference of the prodenia litura, and has important significance for green prevention and control of the prodenia litura.

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...
