Bio-intensive management of thrips in horticultural crops (Chilli, Capsicum, Onion)






  1. Isolation, mass production of potential natural enemies of thrips
  2. Bio- efficacy of potential natural enemies (parasitoids, predators and pathogens) for thrips  on capsicum, onion, Rose and chilli
  3. Field efficacy of botanicals, biological control agents, bio- pesticides and chemical pesticides against thrips on capsicum, Chilli, Rose and Onion. 
  4. Development of  Bio- intensive management of  thrips on capsicum, onion, rose and chilli
  5. Developing formulations of entomopathogens
