Abstract:
Population dynamics of associated fauna of lac insect Kerria lacca (Kerr.) in kusum host plant kusmi strain winter crop was conducted during 2015-16 and 2016-17 at Kanker district of Chhattisgarh. In the present studied population dynamics of various insect associated with lac insect in kusum host plant kusmi strain winter seasons was recorded in five blocks of Kanker district. It was indicating that the population dynamics of various insect viz. E. amabilis was recorded with peaked density (9.65 and 9.40/30 cm stick lac) on second fortnight of August and P. pulverea with peaked density (7.15 and 7.25 /30 cm stick lac) on first fortnight of September as major and Chrysopa. sp. was recorded as minor predators in kusmi strain winter seasons. Among the Parasitiods T. tachardiae was recorded with peaked density (6.85 and 7.15 /30 cm stick lac) as major potential parasitoids whereas A. purpureus, E. tachardiae and Parechthrodryinus clavicarnis was recorded as minor parasitoids and also recorded the beneficial fauna (Hyper-parasitoids) B. tachardiae, Pristomerus sulci and B. greeni in kusmi strain winter seasons.
