Research Accomplishments: 

(During the Period of 2019-2023) 

  1. Assessed insecticide resistance in T. absoluta from different field populations from South India
  2. Identified involvement of four new CYP genes in governing insecticide resistance in T. absoluta.
  3. Studied RNAi-mediated control of T. absoluta through exogenously applied dsRNA delivery on tomato.
  4. Studied virus-vector –host-endosymbiont interactions and identified protein receptors in Bemisia tabaci that interact with Tomato leaf curl Bangalore virus (ToLCBV) coat protein through application of infusion Smart technology and Y2H.
  5. Plant based EC (Emulsifiable concentrate) formulation developed from Annona squamosa having very significant mortality of sucking pests particularly, aphids.
  6. Associated in development of CRISPR-based detection of invasive insect pests

 

Varieties / Technologies Developed: 
  1. Associated in development ARKA BHARATH, a teasel gourd variety
  2. Annona based formulation for management of aphids under organic cultivation
