Abstract
Insect vectors are known to cause significant losses in agroecosystem by transmitting pathogens that cause diseases. The control of these insect vectors mainly relies on insecticides. The over-reliance on insecticides gave rise to problems like insecticide resistance and resurgence in insect vectors. Paratransgenesis is one of the novel strategies that aims to keep transmission of pathogens in check by transferring genetically engineered symbionts in the guts of vectors to express molecules that are deleterious to pathogens they transmit. In similar lines these modified endosymbionts are known to improve the vigour and health of honey bees. So, this manuscript highlights some of the success stories of paratransgenic applications in agriculture and apiculture.
