Chemical constituents and toxicity assessment of the leaf oil of Lantana camara Linn from Tamilnadu regions

Plant secondary metabolites derived from weeds, medicinal and aromatic plants have been found to be a protective biopesticidal agent, cost effective and safe to ecosystem & public health. In the present investigation, the essential oil of Lantana camara collected from the different agro-climatic conditions of Tamilnadu regions has proven to be interesting source of terpenoid derivatives for their biopesticidal properties against some of the defoliators of forestry tree species. Bioassay confirmation of those terpenoids identified from the essential oil was tested on the target pests such as Hyblaea puera, Eligma narcissus and Atteva fabriciella at different concentrations both in the laboratory and field conditions. The bioactivity interms of larval mortality was observed when the early instars were exposed to preformulated oil applications.
