Abstract
Botanical insecticides are naturally occurring chemicals that are obtained from plants. This study aims to analyse the insecticidal activity of compounds present in the ethanolic extract of citrus aurantium peel. The solvent extraction method was used to get the ethanolic extract and the compounds were identified using GC-MS. The insecticidal activity of the ethanolic extract was studied by diet incorporation method. The feed deterrence index and their metabolic rates were assessed. At 40% concentration, the feed deterrence index was observed to be 46.6% and reveals that feed deterrence index increases with the increase in concentration. The consumption rate was observed to be 0.020g/day and denoted that, the consumption rate decreases with the increase in the concentration. The growth rate, efficiency of conversion of ingested food, approximate digestibility and efficiency of conversion of digested food were assessed to be 0.10 g/day, 10.7%, 61.36% and12.36% respectively. The insecticidal likeliness property of the compounds were evaluated using Tice rule and further the binding efficiency were studied using molecular docking against acetylcholinesterase, carboxylesterase and protease of Spodoptera litura. From the docking studies the compound Heptanoic acid,2-methyl, methyl ester from the ethanolic extract have the best interaction with Acetylcholinesterase and carboxylesterase with the least energy value of -79.6 and -76.7 respectively. The seed germination rate was higher at 5% & 10% concentration that is as the concentration of the ethanolic extract of Citrus aurantium decreases the seed germination rate increases. Thus the results could be used as the novel insecticide against the Spodoptera litura.
