When bugs and insects ignore the repellent you rub onto your arms and legs, it can be most annoying.  But when they ignore the insecticides placed on foods and crops, it can be devastating for many, especially in the developing world.  Fortunately scientists have developed a new technique using a chemical derived from the Sassafrases tree — a technique that makes pesticides more effective by removing an insect’s ability to exhibit resistance. Already tested on whiteflys in Spain and Australia and shown to be almost one hundred percent effective, scientists are optimistic this new technique will significantly reduce the amount of pesticides that need to be sprayed on foods.  No doubt this new pest control technology is creating quite a buzz.
