Defensive Response of Corchorus olitorius in Relation to Infestation of Anomis sabulifera

Abdul Sadat , Shubham Bhattacharyya, Subhrajyoti Roy and Kaushik Chakraborty

Background and Objective: Corchorus olitorius, an important fiber crop in Indian economy, is infested by many pests causes it to evolve protective defense against them. In present era, Anomis sabulifera is a major threat to jute agronomy. In this study, the morphological and phyto-chemical defense strategy of jute against A. sabulifera was determined. Materials and Methods: Jute leaf phenology was studied along with standard biochemical and spectrophotometric procedures for the quantification of phyto-chemicals like saponin, alkaloid, flavonoid, tannin, riboflavin, ascorbic acid, thiamine, soluble sugar, protein, lipid, total moisture and ash content. The results were correlated with the pest incidence. Results: Phenological characters were improved throughout the jute cultivation period whereas leaf bio-chemistry showed an altered pattern. After pest menace there was depletion in leaf nutrient content although secondary metabolite concentration was found to be increased following pest attack. Conclusion: It was concluded that, C. olitorius have no morphological defense strategy against A. sabulifera whereas it has evolved itself via phyto-chemical defense mechanisms to protect from pest attack. These findings may be helpful to plan better cultural strategy and pest control programme in near future.
