Microbial pathogens are disease-causing organisms that are spread in vast quantities in the pest population, similar to how chemical pesticides are applied. These microorganisms are utilized through introduction or inundative applications for organic control of bug bothers. Insects are vulnerable to a variety of illnesses brought about by infections, microscopic organisms, the parasite, protozoa, and nematodes, among different microorganisms. Insect microbial pathogens are being studied in depth in order to develop environmentally acceptable pest management solutions for agriculture. These days, plant protection environments and insect pest control are hampered by the development of chemical resistance and residues at higher trophic levels. Bio-pesticides have been replacing chemical pesticides to protect nontarget creatures from the harmful effects of chemicals in recent years. This research discusses the insecticidal characteristics of microorganisms, just as their potential utility in bother the board.

Summary Introduction: Feronia limonia (synonyms: Feronia elephantum, Hesperethusa crenulata, Limonia acidissima Linn, Schinus limonia) is a member of Rutaceae family. F. limonia is an aesthetically pleasing plant with various medicinal and nutraceutical properties. Objective: The primary objective of this research was to determine the flavonoid from F. limonia. Methods: Different solvents have been soxhleted to the roots of F. limonia powder. Column chromatography was performed using silica gel, a yellow amorphous solid was obtained from ethyl acetate extract after elution with hexane: ethyl acetate (4:8). Results: We have successfully isolated a unique geranyl flavanone from the roots of F. limonia. The structure was verified as 8-(2′′,3′′-epoxy-3′′-methyl butyl)-4′-prenyloxy flavanone-7-O-6′′′′-acetyl β-D-glucopyranoside. Conclusion: According to the findings based upon spectroscopic analysis, a hitherto unknown flavanone was isolated in the F. limonia.
