Problems solved by technology

Light trapping and sweet and sour liquid trapping can be used, but due to environmental conditions, the use of black light and sweet and sour liquid for control has limitations
Traditionally, chemical control is mostly used, but a large amount of chemical pesticides will not only make Spodoptera spp., but also cause people to worry about the safety of crops. Therefore, agricultural scientists have gradually turned chemical control into biological control.

Embodiment 1

[0017] Embodiment 1 screens the best formula of attractant for Spodoptera chinensis

[0018] Add dropwise the n-hexane solution containing the sex attractant of Spodoptera spp. After the n-hexane volatilizes, the lures containing the sex attractant of Spodoptera sp. Put the lure core in the box-shaped trap, and then place the trap in the field where the occurrence of Spodoptera moth is more serious. In order to ensure the release effect, 200-2400 μg of sex-attractant of Spodoptera spp. was placed in every 1mL of rubber lures, the average distance between traps was 10m, the height of lures was set at 100cm from the ground, and the trap type was boat-type trapping device. In order to further illustrate the feasibility of the present embodiment, 10 specific formulas are provided in table 1

[0021] After placement, survey the number of spodoptera that was trapped once every two days, and change the trapping position randomly, and continue to inves...

Embodiment 2

[0026] Example 2 The optimal height of the field screening trap for the sex attractant of Spodoptera broad-legged moth

[0027] Adopt formula 9 in the embodiment 1 to prepare the lure core, select the soybean field in Yanqing area that the amount of Spodoptera sp. sp. is relatively large, the area is more than 10 mu, and the distance between the traps is about 10m. Place the above-mentioned spodoptera sp. sp. The box-type traps of agents were used, and 3 replicates were set up for each treatment. Different trap heights are set, and in order to further illustrate the feasibility of this embodiment, 10 different trap heights are provided in Table 3.

Abstract

The invention discloses a sex attractant for protoschinia scutosa and application thereof, and belongs to the technical field of insect sex pheromone preparation. The sex attractant comprises cis-7-dodecene acetate, cis-11-hexadecene-1-ol and cis-9-tetradecene-3-methyl-2-butenoate according to a mass ratio of (2.5-3.5): (1.5-2.6): (0.5-1.5). The provided sex attractant is simple to prepare, convenient to use, strong in trapping capacity and good in stability; the specificity is high, resistance is not generated, no harm is caused to natural enemies, no toxicity is caused to people and livestock, and environment friendliness is achieved; the lasting period is long, and the control effect can be maintained for more than 30 days. The sex attractant can be applied to insect condition monitoring, mass trapping and mating interference of protoschinia scutosa, and is of great significance to comprehensive treatment of protoschinia scutosa.

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 platychina and its preparation method and application. Background technique [0002] Schinia scutosa belongs to Lepidoptera, Noctuidae, and is an important agricultural pest. Widely distributed in eastern, southern, and central Asia, Europe, and northern America. In my country, it is mainly distributed in Hebei, Shandong, Liaoning, Inner Mongolia, Jiangsu and other places. The host plants of Spodoptera broad-legged moth include leguminous plants, Artemisia genus, and Chenopodium genus, and they mainly cause damage through larval feeding. Like other herbivorous Noctuidae insects, this insect is gluttonous and can cause great damage to crops. In northern Xinjiang, Spodoptera spp. is far more harmful than cotton bollworm. In 2017, Spodoptera spp. cause major economic losses. The insect has a strong reproductive ability,...
