y ground them up and applied them to pellets of artificial diet. They then fed the pellets to another cycle of caterpillars. The researchers looked at the survival rates of the bacteria over several generations and found that urease-producing phenotypes survived better when repeatedly fed to gypsy moths.

The results bring scientists a step closer to finding a Bt strain that will be more effective at combating gypsy moths and possibly other insect pests. The efforts could also lead to the discovery of Bt strains that grow on mulch, fight pests on specific crops and thrive in gardens.
