Scientists discover rare 'gene-for-gene' interaction that helps bacteria kill their host

...Exeter University. "Photorhabdus is an important biocontrol organism that is used to control insect pests and reduces pesticide use, so the more we know about it, the more useful it can be. "Insects are the major players in almost every ecosystem on the planet, so we need to know as much as we can about th...

Fight weeds with plant pathogens

...oach and the bioherbicides approach. The classical biocontrol approach uses a pathogen imported from a foreign location to control a native or naturalized weed with minimal technological manipulations. "Classical biological control using imported pathogens has an overall success rate of 57 percent and has be...

Viral hitchhiker inhibits Wolbachia bacteria's ability to proliferate

... could impact the development of virally delivered biocontrol tools for insects that transmit pathogens to humans or harm agriculture. It might also enable the design of alternative therapies for debilitating illnesses such as river blindness and elephantiasis, whose pathologies are caused by Wolbachia bacteria...

The very defensive caterpillar

...as bacteria, fungi and nematodes are often used as biocontrol agents against insects. It had always been assumed that insects in the field would be nave to such control agents but these results raise the possibility that control with one pathogen may confer resistance to another. Most experiments on insect immu...

Schizophrenic antifungal bacteria

... The phase variation mechanism in these so-called biocontrol bacteria is reversible. Therefore switching between the two phases enables the entire population to respond to changes more quickly. This is a clear competitive advantage. Stressful conditions result in a switch to the non-medicinal form, which incre...
