Lac is a resinous secretion produced by lac insects that is cultivated for commercial use. The document outlines the history, cultivation methods, host plants, and uses of lac. Key points include that lac cultivation involves selecting and pruning host trees, inoculating them with broodlac bundles, harvesting immature resin or mature broodlac, and that the main host plants are Butea monosperma, Ziziphus mauritiana, and Flemigia semialata. Lac has various applications in products like paints, electrical goods, and cosmetics.

3. Introduction
Lac is the resinous secretion of a number of species
of lac insects, of which of the most commonly
cultivated species is Kerria lacca and Laccifer
lacca (India).

4. History
 The word lac is derived from
the Sanskrit word lākshā' (लाक्षा), which represents the
number 100,000.
 Tachard is known as a father of lac insect.
 The first scientific or detailed study of the lac insect
was given by j. kerr in 1782.

5. Methods of Lac Cultivation
 Selection of trees and area
 Pruning of host trees
 Inoculation of host tree
 Removing of used-up broodlac sticks(phunki)
 Harvesting

6. Selection of Trees and Area
 The trees are normally found in a groups, either on
plains or in sub hilly areas or on border of paddy
fields.
 Dense canopy of tree, water bodies or dense forest is
preferred for summer crop.
 Open areas and isolated trees are preferred for rainy
season crop.

7. Pruning of Host Trees
 The operation is carried out six months before
inoculation for summer crop in the month of april.
 The pruning is done on a february for rainy season
crop.
 Shoots between 1.25-2.5cm diameters should be cut.

8. Inoculation of Host Tree
Tying of broodlac bundles on an branches of host trees
for spreading of lac insect on succulent shoots is called
inoculation.
Equipments of inoculation
1.60mm mesh
2.Synthetic net bag
3.Treads for tied on tree kerria lacca

10. Removing of used-up Broodlac
Sticks(Phunki)
 The used-up broodlac sticks should be removed from
inoculated tree as soon as emergence of lac larvae is
stopped.
 Normally this period is 15-20 days after tying of
bundles on tree.
 This period should not exceed 21 days in any case.

12. Harvesting
1.The crop is harvested either as an immature summer
crop (resin value) or mature crop as broodlac(lac
insect value).
2.Immature summer lac can be cut at any time when
encrustation becomes relatively thicker.
3.Normally broodlac is harvested in October-November
when crop matures

13. Uses
 Used in preparation of varnishes, paint, toys, bangles,
electrical goods, gramophone records and buttons.
 Lac is used as insulating and sealing agents.
 Nail polishes and dyes making.
 Wood finish.
 Juices.
 Skin cosmetics.

14. Host Plants
 Palas - Butea monosperma
 Ber - Ziziphus mauritiana
 Semialata - Flemigia semialata
 Kusum - Schleichera oleosa
 Khair - Acacia catechu
 Babul - Acacia arabica
 Arhar - Cajanus cajan

17. References
 Samiksha S. ,Scientific study of lac started much later.
In 1709 Father Tachard discovered the insect that
produced lac. First of all Kerr (1782) .
 Dr A K Jaiswal and Dr J P Singh (2015),The trees are
normally found in a groups, either on plains or in sub
hilly areas or on border of paddy fields.

18. Conclusion
The lac host plants shoots should be maintain properly
because the lac production is totally depend on the
good and vigorous of the host plants, so shoots be
required fully under care and management during the
cultivation.
