Abstract: Kusum (Schleichera oleosa Oken.) is a major host plant for Indian lac insect (Kerria lacca Kerr.). This lac insect produces a resin known as lac via complex lac insect-host plant interaction. This resin acts as a protective covering over its body which was secreted by sucking the phloem sap from the stem of the host plant. This resin has several commercial applications ranging from paint, varnishes to aleuritic acid. This insect-plant interaction has been exploited by several communities especially tribals residing around the forest areas of Jharkhand, Chhattisgarh, Madhya Pradesh, West Bengal, and Odisha states of India. To elucidate the impact of lac insect feeding on kusum host, Kusmi strain of Indian lac insect was inoculated (infested) and compared with non infested condition (control). From the pooled data over two years it was observed that total sugar, soluble protein and free phenol level were increased in the leaves of lac insect infested host plant as compared to control. Proline also recorded an abrupt increase in level as compared to control whereas non significant increase was observed in malondialdehyde level. Superoxide radical, hydrogen peroxide and ascorbic acid level were also elevated upon lac insect feeding on host plant Kusum as compared to control. Thus, the study reveals that a dialogue between insect and host plant occurs at cellular level when lac insect feeds on host plant Kusum, thus significantly altering primary and secondary metabolism of host plants to ensure its survival along with host plant.
