Problems solved by technology

Although sex pheromone has the advantages of strong selectivity, trace efficiency, and environmental friendliness, it can only trap and kill male individuals of the same species, and it can have a good effect on pests with more than one generation. When the population density of wild female moths is high It cannot achieve the desired effect, therefore, it needs to be continuously optimized to achieve a better trapping effect

Embodiment 1

[0017] The preparation of embodiment 1 silver-leaved sex attractant composition lure core

[0018] Add the n-hexane solution containing the synergist dropwise on the lure containing the sex pheromone of the silver-leaved armyworm, after the n-hexane solution volatilizes, then drop a certain amount of n-hexane solution on the lure, wait until After the alkane solution is completely volatilized, the lure core containing the silver-leaved moth sex attractant composition is prepared, and the lure core is placed in a box-type trap, and then the trap is placed on a field where the occurrence of silver-leaved armyworm is relatively serious. . Table 1 provides different synergists. In order to ensure the release effect, 750-1500 μg of the silver-leafed sex attractant composition is placed in each rubber lure core. In order to further illustrate the feasibility of the present embodiment, Table 2 gives 18 specific recipes were produced.

Embodiment 2

[0025] The lure core of embodiment 2 different formulations is to the mensuration of the trapping effect of silver leaf moth

[0026] Select plots with serious occurrence of silver-leaved moth, with an area of ​​more than 20 mu, set the lure core at a height of about 150cm from the ground for each formula, and the distance between the traps at about 15m, and place the above-mentioned sex-attractant containing silver-leaved moth at random Combination box-type traps, each treatment set up 3 replicates. The number of silver print moths trapped was investigated every two days after placement, and the trapping positions were changed randomly, and the investigation continued for 30 days.

[0027] The survey results are shown in Table 3:

[0031] From the results in Table 3, it can be seen that adding one or two synergists to the sex pheromone of Autographa can increase the number of trapping males of Autographa to a certain extent, but ther...

Abstract

The invention discloses a three-spotted plusia sex attractant composite and application thereof, and belongs to the technical field of insect sex pheromone preparation. The sex attractant composite comprises three-spotted plusia sex pheromone and synergists. Wherein the components of the sex pheromone are cis-7-dodecene acetate, cis-11-hexadecane acetate and cis-11-hexadecane aldehyde; the synergists are mainly one or more of plant volatile 2-ethyl-1-hexanol, ar-turmerone and pentanal; mass ratio of the sex pheromone to the synergists is 1:0.3-1.2. The composite has the advantages of simple preparation and convenient use, the composite can be accurately used for the insect pest monitoring, massive trapping and mating interference of the three-spotted plusia, and the composite has significant meaning on comprehensively treating the three-spotted plusia.

Description

technical field [0001] The invention belongs to the technical field of preparation of insect sex pheromones, and in particular relates to a sex attractant composition and application of silver-leaved armyworm. Background technique [0002] Argyrogramma agnata (Staudinger) belongs to Lepidoptera, Noctuidae, and is an important agricultural migratory pest. It mainly hosts cruciferous vegetables such as rapeseed, cabbage, cauliflower, cabbage, and radish, as well as legume crops, kale, eggplant, and other crops. The larvae feed on the leaves of plants, causing holes or nicks or even death in the leaves, and excrete feces to pollute the vegetable plants, seriously affecting the quality and yield of crops, and causing serious economic losses. Silver leaf moth is distributed all over the world, and it is mainly distributed in major soybean producing areas in China. Among them, the Huanghuai River Basin and the Yangtze River Basin are severely affected. There are 1 to 5 generation...
