Study uncovers optimal ecology of bioinsecticide
Date:5/20/2010

BBSRC funded researchers at the University of Oxford and Royal Holloway University of London have discovered that the commonly used and naturally occurring bacterial insecticide Bt works best if applied to young plants and is enhanced by the presence of the insect pests. The research is published today (20 May) in the open-access journal PLoS Pathogens.

Spraying Bt the bacterium Bacillus thuringiensis is a common method for controlling a variety of insect pests and is one of the main approaches to chemical-free pest control in agriculture. Optimising sustainable farming techniques can help meet the challenge of feeding 9 billion people by 2050 using fewer resources and with minimum impact on the environment.

Senior researcher Dr Mike Bonsall at the University of Oxford said: "Bt has been used commercially for about 40 years and is readily available to control pest moths and the like, but until now we've known very little about the natural abundance of the bacteria in the environment and what happens when we apply extra bacteria as a means of pest control. It's really important to understand what is happening so that we can, for example, know what factors might have an impact on the insects becoming resistant to Bt."

Bt is found naturally in soils and on plants and exists as many different varieties that each have a preference for infecting different organisms. Bt strains that are specific to certain insects rely on being able to infect those insects in order to reproduce. The researchers studied a strain called ST8, which infects the Diamondback Moth a pest that attacks cabbages, broccoli and related crops and they found that the population of bacteria (either existing or applied) establishes itself more readily when the insects are present.

The team set up several cabbage plots in the field to examine what was happening when there were extra insects and/or extra
