Regional release method of aedes albopictus carrying wolbachia at fixed position

Abstract

The invention discloses a regional release method of aedes albopictus carrying wolbachia at a fixed position. The method comprises the steps of selecting a place near a mosquito breeding ground and a habitat as a releasing point in a release region according to different landforms and surrounding environment, wherein, the habitat is wet, shading and the vegetation there is vigorous; cleaning water in the release region and a container where the mosquito would possibly lay an egg; using a BG-Trap adult mosquito trapping apparatus at a releasing point for trapping the aedes albopictus; calculating male mosquitoes trapped by the BG-Trap adult mosquito trapping apparatus; then conducting PCR detection to the male mosquitoes to determine if the male mosquitoes carry Culex wolbachia; calculating the number of positive male mosquitoes carrying the Culex wolbachia and the number of negative male mosquitoes not carrying the Culex wolbachia respectively to obtain a release proportion; and then releasing the positive male mosquitoes carrying the Culex wolbachia at a fixed releasing point in a release proportion more than or equal to 5.

Description

Technical field [0001] The invention belongs to the field of mosquito control, and specifically relates to a fixed-point and zoned release method for Aedes albopictus carrying Wolbachia. [0002] Background technique: [0003] Wolbachia was extracted from fruit flies, Aedes and Culex mosquitoes and successfully introduced into the dengue fever vector Aedes albopictus, establishing a stable mosquito strain carrying a new type of Wolbachia. The eggs produced by mating male mosquitoes carrying Wolbachia with non-Wolbachia female mosquitoes cannot develop. By releasing a large number of male mosquitoes carrying Wolbachia, the mosquito population can be reduced to a level not enough to cause dengue fever. [0004] Then consider that the release area of ​​the Aedes albopictus carrying Wolbachia is very large, and the topography of the release site is very complicated. How to release the release method that can not only reduce the release amount but also achieve good results is an urgent ...

AI Technical Summary

Problems solved by technology

[0005] At present, foreign countries use the method of releasing while walking by car to cover the entire surface in order to achieve an even distribution in each area. However, this method of releasing has a disadvantage, that is, the number of possible breeding places and possible habitats for mosquitoes may be relatively small. There may be relatively more non-bad habitats and non-habitats, which will affect the suppression effect
