Description
Technical Field
The invention belongs to the technical field of multiplex PCR, and particularly relates to a method for rapidly identifying common storage spider mites based on the multiplex PCR technology.
Background
The flour mites belong to Acarina (Acari), Eudermans (Acariformes) and Astigmata, are small in size, various in variety and wide in habitat, can be bred in a large amount in the stored substances, mainly eat organic residues of plants or animals, but mainly take stored grains, dried fruits, fur and the like in the stored substances. The aleyrodids not only cause great loss of quality and quantity of stored materials, but also can cause mite allergic diseases, even lung acariasis, intestinal acariasis, uroacariasis and the like. Under the global economy, the frequency and the convenience of international trade and tourism provide convenience for the international spreading and diffusion of the pink mites, and 98 kinds of the pink mites which are known to be widely harmful worldwide are provided, wherein the common pink mites comprise: spider mites (Acarus sroro), Tyrophagus putrescentiae (Tyrophagus putrescentiae), Dermatophagoides naesbioti (Suidasia neostiti), Dermatophagoides pteronyssinus (Dermatophagoides pteronyssinus), Dermatophagoides farinae (Dermatophagoides farina), and Lepidoglyphus insect (Lepidoglyphus destructor). In recent years, the flour mites are pests which are often captured by entry and exit, and the inspection of the flour mites has become an important aspect of the inspection of the entry and exit of stored grains. In the real-time detection of the stored grain mites entering and exiting a large number of agricultural product trades, the demand for a simple, quick, economic and accurate identification technology is urgent.
At present, the identification of the imported quarantine flour mite is mainly carried out according to the morphological characteristics. Due to the tiny size and various varieties of the flour mites, the rapid and accurate identification is quite difficult when the flour mites frequently encounter diseases such as young stages (including eggs, larvae, nymphs and dormant bodies), hidden species and damaged samples. In recent years, molecular marker-based techniques have been widely used in the field of species identification. Among them, the transcribed internal spacer 2(ITS2) of ribosomal gene has a high rate of evolution, and thus has a large difference in sequence length and base composition even in closely related species, and is widely used as an effective molecular marker. The method for identifying the acarid based on the molecular marker technology comprises the following steps: polymerase chain reaction and PCR-RFLP, but the above method steps are complicated and the identification time is long.
Disclosure of Invention
According to the defects of the prior art, the technical problem to be solved by the invention is to provide a method for rapidly identifying common storage spider mites based on a multiplex PCR technology, the method overcomes the problems in the existing technology for identifying common storage spider mites, firstly, the genomic DNA of a single spider mite is extracted, the extracted DNA is used as a PCR template to perform clone sequencing and analysis of ribosome ITS sequences, and 6 specific downstream primers are designed based on the sequence length and the difference of base composition of ITS2 and are respectively named as Acas-R (Dermatophagoides farinae), Tyrp-R (Tyrophagus putrescentiae), Suin-R (Suin-crinophagus naeslunensis), Derp-R (house dust mite), Derf-R (dust mite) and Lepd-R (lepidoptera pest). As 5.8S is well conserved among different species of aleyrodids, an Asti-F primer is designed as a universal upstream primer of 6 specific primers. Multiple PCR amplification is carried out on the basis of a reaction system and a program of common PCR, and the identification of 6 common storage spider mites is realized simultaneously through agarose gel electrophoresis. And subsequent experiments prove that the primers have no obvious difference in amplification results no matter whether the primers carry out common PCR specific amplification or multiple PCR specific amplification, and prove that the multiple PCR primers designed by the invention have high specificity. Only one PCR reaction is needed, 6 different product lengths can be amplified simultaneously, and 6 aleyrodids can be directly identified by simply judging the sizes of the products.

2. Compared with the traditional morphological identification, the method does not need a complete specimen, can also identify the residue and the young stage (eggs, larvae and nymphs), and has higher accuracy and specificity of the identification result. The experimental result shows that for the same aleyrodids, the primer has specificity no matter whether the primer carries out common PCR specific amplification or multiplex PCR specific amplification, and the amplification results have no obvious difference.
