( and remove the need for constant reappl...)Hanging baskets of sex and death help fruit growers

In this Defra funded project the researchers have already tested the effect of a single dispenser which alone infected 5% of all the moths found over a 1 hectare site. That early test helped them maximize the best virus formulation, and the most efficient dispenser design that maximised access for the moths while protecting the virus from sunlight and other elements, and the best form of pheromone lure. That test also helped them choose between a liquid and powder based mix for the virus - the liquid was found to be best. The University of Warwick researchers are now working with colleagues from East Malling Research on a larger scale 12 hectare trial of the dispenser in a large commercial apple orchard in Worcestershire. An array of 25 dispensers per hectare have been erected over 3 separated orchard plots of one hectare within an even larger orchard. The codling moth control within these three 1 hectare plots will be compared to similar sized orchard plots with dispensers without virus, or no treatment or sprayed with a commercial virus spray at the same virus dose.
