Abstract
The invention provides a method for rapid detection of nuclear polyhedrosis virus by LAMP. The F protein of larix geometrid nuclear polyhedrosis virus is used as the target gene, and the specific loop-mediated isothermal amplification (LAMP) primer set p7 is designed and synthesized. The p7 sequence of the primer set is shown in SEQ ID NO: 37-42. Using isothermal amplification technology for detection and analysis, it can realize rapid detection in 10 minutes, with a sensitivity of more than 1 million times, and has good specificity. The sensitivity of fluorescent LAMP and chromogenic LAMP is consistent. Thus, the detection efficiency and sensitivity of LAMP for detecting nuclear polyhedrosis virus are greatly improved.
Description
technical field [0001] The invention relates to the technical field of virus detection, in particular to a method for rapidly detecting nuclear polyhedrosis virus by LAMP. Background technique [0002] Nuclear polyhedrosis virus is a natural control factor of Lepidoptera insects. The virus spreads rapidly and spreads rapidly among species. It is an important control measure and can reduce forestry economic losses. Establishing a rapid and accurate detection technology for nuclear polyhedrosis virus will help to know early whether there is a virus in the pest, whether a large amount of virus needs to be sprayed, and whether the pest is infected by the virus after the control measures are taken to achieve effective control Wait. However, the existing conventional PCR method for detecting nuclear polyhedrosis virus has problems such as long time-consuming, relatively complicated operation, cumbersome instrument steps, and high cost, which affect its practicability.
