Wolbachia is a genus of gram-negative bacteria that infects arthropod species, including a high proportion of insects, and also some nematodes. It is one of the most common parasitic microbes and is possibly the most common reproductive parasite in the biosphere. Its interactions with its hosts are often complex, and in some cases have evolved to be mutualistic rather than parasitic. Some host species cannot reproduce, or even survive, without Wolbachia colonisation. One study concluded that more than 16% of neotropical insect species carry bacteria of this genus, and as many as 25 to 70% of all insect species are estimated to be potential hosts.
A genetic control method for monochamus alternatus
The application provides a method for preventing and treating monochamus alternatus, which comprises putting male monochamus alternatus carrying Wolbachia into a target prevention and treatment area of monochamus alternatus not carrying Wolbachia. The method has low investment cost, is green, safe, environment-friendly, has no pesticide residue and high risk, conforms to the green prevention and control principle and needs of diseases and pests in the new era, is less affected by external temperature, humidity and other climate environments, is suitable for wide plots, is a new prevention and treatment method, is early in the prevention and treatment period, prevents and treats from the egg stage, reduces the double hazards of the larval stage dry woodworm and the pupal stage adult stage spreading pine wood nematode disease from the root, has good prevention and treatment effect, and can significantly reduce the egg hatching rate of monochamus alternatus by more than 90%.
