Lac insects belong to the super-family coccoidea (Hemiptera: Sternorrhyncha), commonly known as scale insects or coccoids, which comprises of about 7,500 species under variable number of families (20 and above). Globally, ninety species of Tachardiidae have been reported under nine genera. Twenty-one species of Kerria have been reported so far. Out of the 14 species of Kerria reported in India, only a few are exploited for commercial lac production. Tree-hosts, depending upon their habit, 15-20 years to reach the stage of lac inoculation and hence, do not find favour with the lac growers for raising systematic plantations to grow lac. To cultivate lac on plantation basis, some short stature, fast growing perennial shrubs have been identified for systematic plantation raising and/or integrating with agricultural crops. Flemingia semialata Roxberg and Flemingia macrophylla Willd have shown great promise for lac production due to its fast growth, tender shoots and suitably for intensive lac cultivation. Being an immobile pest, generating information on biology under the local conditions is essential. Information on crawlers, anal tubercles, respiratory pores and embryonic development were identified. The study is helpful in designing future integrated management of this pest.
