The use of botanicals is one of the prominent methods to protect crops and crop produces from insect pest infestation. Though many phytochemicals have been identified as biopesticides, its presence in a weed crop has necessitated extracting of such botanicals which increase the utility of it. The west Indian lantana or, Big-sage or Lantana (Lantana camara L.), native to Tropical America is an invasive weed species across the globe and is a rich source of bioactive molecules present in leaves, flowers, fruits, seeds and other plant parts with insecticidal activities on crop, stored grain and household pests. Oil, water and organic solventbased extraction from various plant parts have growth, behavioral modifying and lethal effects on many defoliators, sucking pests, stored grain pests and household pests. Out of many compounds characterized from the essential oil of L. camara, α-Copaene, Germacrene D&B, α-Cubebene, β-Elemene, α-Guaiene, α-humulene, Aromadendrene, β-Selinene, α-Selinene, Caryophyllene oxide, Nerolidol, Spathulenol and Delta-Cadinene have expressed tritrophic interactions as well as insecticidal activities in terms of larval mortality against certain pests. These findings have tremendous scope for utilization of extracts from L. camara as biopesticide and as a component of integrated pest management in field crops and stored products.
