Problems solved by technology

According to investigations, the traditional method of spraying pesticides is still used in the prevention and control of bamboo elephants in vast forest areas. This will not only cause harm to humans and animals and the surrounding ecological environment, but will also kill other beneficial insects innocently, seriously destroying the population and insect biological chain
So far, although there are some reports on the study of bamboo weevil's living habits and chemical, biological and artificial control of bamboo weevil pests, we have not yet seen relevant literature on the in-depth analysis of bamboo weevil pheromones and the use of pheromones for comprehensive pest control

Embodiment 1

[0036] A method for preparing a pheromone for trapping weevils, which is carried out sequentially according to the following steps:

[0037] ①Measuring and batching: In a clean indoor environment, measure and weigh the raw materials according to the following weight ratios for batching:

[0038] 1 part of benzaldehyde,

[0039] 0.05 parts of benzoic acid,

[0040] 0.60 parts of linoleic acid.

[0041]② Stirring and mixing: put the raw materials of benzaldehyde, benzoic acid and linoleic acid weighed in the step of weighing and proportioning into the mixer, and carry out stirring operation under normal temperature and pressure to make it evenly mixed, and control the mixing operation time to 15min. A mixed material is produced.

[0042] ③Sieving and removing impurities: Send the evenly stirred mixed material into a 200-mesh metal mesh sieve for screening, and remove impurities through screening to obtain uniform fine materials.

[0043] ④Separate bottle encapsulation: Send ...

Embodiment 2

[0045] A kind of preparation method of the pheromone of trapping weevil, it is to carry out according to the following steps:

[0046] ①Measuring and batching: In a clean indoor environment, measure and weigh the raw materials according to the following weight ratios for batching:

[0047] 1 part of benzaldehyde,

[0048] 0.02 parts of benzoic acid,

[0049] 0.07 parts of linoleic acid.

[0050] Then carry out the steps of "2. Stirring and mixing, 3. Screening and removing impurities, 4. Bottle packaging" in the manner described in Example 1 to obtain 1 part of benzaldehyde, 0.02 part of benzoic acid, and 0.07 part of linoleic acid. The pheromone finished product for trapping weevil insects composed of the weight ratio.

Embodiment 3

[0052] A kind of preparation method of the pheromone of trapping weevil, it is to carry out according to the following steps:

[0053] ①Measuring and batching: In a clean indoor environment, measure and weigh the raw materials according to the following weight ratios for batching:

[0054] 1 part of benzaldehyde,

[0055] 0.01 parts of benzoic acid,

[0056] 0.02 parts of linoleic acid.

[0057] Then carry out the steps of "2. stirring and mixing materials, 3. sieving and removing impurities, 4. packaging in separate bottles" in the manner described in Example 1 to obtain 1 part of benzaldehyde, 0.01 part of benzoic acid, and 0.02 part of linoleic acid. The pheromone finished product for trapping weevil insects composed of the weight ratio.

Abstract

The invention discloses a pheromone for trapping snout beetles and a preparation method of the pheromone. On the basis of deeply knowing a biological mechanism that cyrtotracjelus longimanus recognizes bamboo shoot volatile matter signals to eat bamboo shoots, edible additives of benzaldehyde, benzoic acid and linoleic acid as raw materials are subjected to steps of metering and blending, stirring and mixing, screening and impurity-removing to be prepared into a pheromone food of strongly trapping the foraging function of the cyrtotracjelus longimanus; and a large quantity of cyrtotracjelus longimanus can be trapped to a nylon trapper for being trapped. The pheromone has the remarkable advantages of being easy to produce, low in manufacture cost, convenient to operate and use, strong in function of trapping the cyrtotracjelus longimanus, remarkable in effects of preventing and controlling the cyrtotracjelus longimanus, and being free from toxicity, harmfulness and pollution, is capable of perfectly coordinating and unifying four aspects of controlling insects, protecting natural enemies, protecting environment and comprehensively utilizing insect resources, and is excellent in popularization and application prospect in a lot of forests.

Description

technical field [0001] The invention relates to an insect pheromone, and also relates to a production method of the insect pheromone, which belongs to the technical field of using pheromones to prevent and control insects and protect the ecological environment, in particular to a pheromone for trapping weevil insects and its preparation method. Background technique [0002] We know: Insect pheromone, also known as insect pheromone, is a trace substance produced and released by insects that transmits information within or between species for chemical molecular language communication and behavior regulation. Modern science has shown that the information transmitted by insect pheromones (such as: foraging, luring, assembly and evacuation warning, mating and oviposition and other functional information) is highly specific, that is to say: every insect released A pheromone has a specific stereochemical structure, and some pheromones are mixtures of several compounds in a certain...
