Effect of Ethyl Acetate Extract and Purified Compounds of Alpinia galanga (L.) on Immune Response of a Polyphagous Lepidopteran Pest, Spodoptera litura (Fabricius)
Journal Title: Asian Journal of Advanced Basic Sciences - Year 2018, Vol 6, Issue 1
Abstract
Plant derived products provide defense to plants against herbivore insects by acting as antifeedant, growth regulators, toxins and modulate the activity of various enzyme. Additionally botanicals can also effect the immune system of insects. The present work reveals the impact of secondary metabolites of Alpinia galanga, a medicinal plant on humoral immune response of Spodoptera litura (Fab.). Addition of ethyl acetate extract and purified compounds viz. galangin and 1’-acetoxychavicol acetate induced the activity of phenoloxidase. Fluctuation in lysozyme activity was observed due to ethyl acetate extract. Although higher concentration of galangin induced the lysozyme level, but 1’-acetoxychavicol acetate did not significantly influence in enzyme level. Understanding the effect of biopesticides in immune response would help to design effective strategies for the control of insect pests.
