Salient Research Achievements
(in bullets)
Collection and Conservations of the Lac Insect Genetic Resources
  • Around 50 lac insect germplasm were conserved and maintained on Flemingia macrophylla for ten years 2011 to 2021.
  • Lac insect was collected from Madurai, Thrissur and Manipur were described as new species, Kerria maduraiensis & Kerria canalis, Kerria thrissurensis and Kerria manipurensis, respectively.
  • Extensive survey in 56 districts of 9 different states viz., Andaman, Assam, Arunachal Pradesh, Kerala, Meghalaya, Nagaland, Tamil Nadu, Tripura and West Bengal were made. New collections of lac insect (9) and lac host plants (8) were added in respective Gene Banks.

Lac insect crop Management

  • Biological parameters viz., initial density, sex ratio, fecundity, cell and resin weight of 55 lac insect lines showed significant difference among the lines which were corroborated with morphological studies.
  • First time Callindra calothyrysis was identified as promising host of Kerria lacca for both strain (rangeeni and kusmi) in all four crops (Baisakhi, katki, aghani and jethwi)
  • Based on the reproductive isolation, Kerria lacca and K. chinensis were confirmed as two different species.
  • First time budded, inarched and grafted plants of F. semialata on F. macrophylla were achieved and also studied Host suitability Index.
  • Improved and accurate method was developed for broodlac quality of lac insects and forecasting of lac insect crawler emergence
  • Developed Seri-Lac Culture Model in collaboration with CSR and TI, Mysore
  • Five models of Lac integrated Agro-forestry System were demonstrated among thirteen tribal farmers in seven villages two districts of Jharkhand

Lac Insect Pest Management

  • Quantitative variation in lac associated fauna was determined which varied between the location, host and crop season. Aprostocetus purpureus, a parasitoid was most prevalent
  • New more precision and accurate method of in-situ parasitoid collection was developed.
  • Eighteen (18 nos.) of lac associated fauna and 6 pests of lac hosts and 3 alternate hosts of A. purpureus was reported first time.
  • Major semiochemicals viz., Decane, dodecane, hexadecane and nonadecane were detected in lac inoculated plants and other major compounds viz. Decane, Dodecane, Tetradecane, Heptadecane, Eicosane and Octacosyl acetate were detected in lac insect and associated products.
  • Electroantennogram study revealed that the antennal receptors of Eublemma amabilis and Pseudohypatopa pulverea were differentially sensitive to lac insect and associated product extracts.
  • Regression models were developed on the population fluctuation of Aprostocetus purpureus on Palas and Ber during baisakhi crops.
  • Palas : Y=-142.09+2.77(Max temp)-1.61(Min Temp)+1.41 (Eve RH)+0.015 (RF)
  • Ber : Y=-25.64+0.47(Eve RH)+0.16 (RF)

Technology commercialized

  • Calliandra calothyrsus – a potential new host for lac insect, Kerria lacca, a technology was developed. It was commercialized in twenty farmers field at Ranchi and Khunti districts, Jharkhand.
  • Lac Integrated Agro-forestry System was commercialized under ICRAF project in 20 farmers field at Ranchi, Khunti and Seraikella Kharsawan districts, Jharkhand
