The application discloses an automatic generation method of an invasive species prevention and control grade map, comprising the following steps: acquiring suitable habitat data of a target species in a target area and spatial data of at least two human interference factors; respectively performing spatial analysis on the suitable habitat data and the data of each human interference factor, dividing a risk grade, and obtaining a plurality of single-factor risk grade maps; weighting and superimposing the plurality of single-factor risk grade maps, calculating a comprehensive risk distribution according to a comprehensive evaluation rule, and generating a prevention and control grade map through reclassification; the method can be encapsulated as a geographic processing model to realize one-key automatic generation. Through systematic integration of natural suitable habitats and human interference factor systems, the application solves the problems of the existing prevention and control division methods, such as disconnection with actual conditions, difficulty in quickly responding to multi-scenario analysis, strong subjectivity and low repeatability, and realizes high-precision fitting of the division results with actual conditions, as well as an objective, stable and repeatable division process.

The application provides a digital PCR kit for detecting highland invasive species red-eared slider and bullfrog, a set of red-eared slider specific primer probes, which are composed of a primer pair for a specific segment of a red-eared slider mitochondrial CYTB gene and a red-eared slider specific TaqMan probe matched therewith; a set of bullfrog specific primer probes, which are composed of a primer pair for a specific segment of a bullfrog mitochondrial 12S rRNA gene and a bullfrog specific TaqMan probe matched therewith, and a set of internal standard (IPC) primer pairs and internal standard TaqMan probes for monitoring the nucleic acid extraction and amplification reaction process monitoring. The application is provided with the primer pair for the specific segment of the red-eared slider mitochondrial CYTB gene and the red-eared slider specific TaqMan probe, the primer pair for the specific segment of the bullfrog mitochondrial 12S rRNA gene and the bullfrog specific TaqMan probe, and a common internal standard to construct a triple detection reaction system, thereby avoiding the quantitative uncertainty caused by the single species detection in the prior art which needs to be carried out in multiple reactions or relies on a standard curve for relative quantification.

Wakeboats that include an aquatic invasive species control apparatus are provided. These wakeboats can include: a wakeboat with a hull; at least one throughhull fitting in the hull of the wakeboat; an irradiation chamber in fluid communication with the at least one throughhull fitting, the irradiation chamber having a radiation source; and at least one water destination aboard the wakeboat. Methods for irradiating invasive aquatic species aboard a wakeboat are also provided. The methods can include: receiving water from outside the wakeboat hull; and irradiating water aboard the wakeboat prior to discharging the water.

The present application belongs to the field of biological detection, and particularly relates to a multiplex PCR primer combination for detecting red-eared turtles based on environmental DNA and application thereof. The present application provides a multiplex PCR primer combination for detecting red-eared turtles in the environment. The present application introduces multiple pairs of primers to simultaneously amplify multiple sites, greatly improving the stability and reliability of detection. Moreover, the present application takes the first mismatch at the 3' end of the primer as the core of specificity discrimination, and sets the difference site of the red-eared turtle relative to non-target turtle and turtle species at the last 1 base position at the 3' end of the primer, so that the primer forms a 3' end terminal mismatch on the non-target template, thereby effectively improving the detection specificity. The present application has low detection cost, simple operation, high detection sensitivity and strong specificity, and can be widely applied to field distribution investigation of red-eared turtles, early warning of invasion and diffusion, and dynamic monitoring of aquatic ecosystems, thereby providing an important technical means for preventing and controlling alien invasive species and maintaining biodiversity.

This invention relates to the field of ecological management technology, specifically to an invasive species eradication device and method. The specific technical solution is as follows: A method for eradicating invasive species employs a cutting mechanism in the eradication device to cut off the invasive species and feed it into a crushing mechanism for crushing. After crushing, the species is discharged onto the ground and sprayed with a reagent. Then, a rotary tillage mechanism is used to dig out the roots of the invasive species and mix them with the crushed invasive species and the reagent. The order of spraying the reagent and digging out the roots of the invasive species can be interchanged. This invention combines physical and chemical control methods to achieve the eradication of invasive species without damaging the local ecosystem.
