Using technology to prevent pest invasions. That’s coming up on This Land of Ours.
This week we’re focusing on technology in agriculture. The USDA’s Animal and Plant Health Inspection Service or APHIS Plant Protection and Quarantine (PPQ) uses the sterile insect technique to prevent invasions of damaging exotic fruit fly pests, which are among the most destructive pests of fruits and vegetables in the world. This technique releases large numbers of sterilized flies to reduce the probability of invasive flies finding fertile mates. PPQ is investigating the use of CRISPR gene editing technologies to develop strains of single-sex fruit flies for use in sterile insect technique programs.
The ability to produce and release large quantities of sterile, male flies can efficiently suppress pest populations that would otherwise damage fruits and vegetables. PPQ is also working to engineer CRISPR antimicrobials to specifically target bacterial pathogens. This effort to overcome antimicrobial resistance and leave beneficial microbes unharmed could allow long-term control of insect pathogens that reduce the efficiency of sterile insect technique programs, and plant pathogens that directly harm crops.
