Growth and health of plants depends on the health substrate or soil, while growth and survival of phytophagous insects depends on the health of its host plants. Similarly, growth and survival of phloem feeders, including Lac insects (Kerria lacca) depends on the quality and quantity of phloem sap access to it. K lacca produce natural resin which is a cash crop and commodity of export. Commercially, K lacca is reared on the naturally standing trees of Butea monosperma, Zizyphus mauritiana and Schleicheria oleosa. But when it is reared on cultivated annual shrubby hosts like Cajanus cajan, soil health matters. In this context, a field experiment was conducted by rearing K. lacca on C. cajan grown on different substrates. The data reveals that the substrate combination of Kapu (45kg) + FYM (20kg) + T. viride was the best as it produced highest lac (288.33g) and seed yield (838.33g) of C. cajan. The survival percent of Lac insect from brood lac inoculation to the harvest of lac crop was highest (41.83%) on C. cajan grown on Kapu (45kg) + FYM (20kg) + T. viride. The study indicates the substrate play a major role in the growth of the host plants and survival of K. lacca.
