Resistance Decoded

It has been found how Rhipicephalis microplus, a tick which transmits various diseases in cattle, has developed resistance to amitraz, one of the main pesticides used against it. Scientists have identified the genetic basis behind at least one form of resistance the tick has developed against the pesticide. The find will help scientists devise a new genetic test which could give farmers better alternatives to manage the tick. Study also suggests using several pesticides for ticks and mites will delay the development of resistance in the tick. Rhipicephalis microplus reduces rate of growth, causes anaemia and even death of cattle.
