AI Technical Summary
The application of existing baculoviruses in the target pest fall armyworm faces resistance issues and also infects non-target beneficial insects. Enhancing the antiviral ability of target pests and avoiding negative impacts on beneficial insects is the key to biological control.
A specific gut strain, Glutamicibactersoli, was screened out. It was isolated, purified, and identified to enhance the fall armyworm's resistance to baculovirus infection, regulate the gut microbiota structure to reduce the infection susceptibility of beneficial insects, and a sterile model was established by feeding antibiotics and then reintroduced with the strain. Virus lethality and gene expression were monitored.
It significantly reduced the mortality rate of insects caused by viral infection, prolonged the median lethal time, inhibited viral gene expression, and enhanced the resistance of fall armyworm to baculovirus, providing experimental evidence and strategies for biocontrol.
