In recent years organic formulations involved in the biological control of insect-pests of economically important plants have been of great value in the field of agriculture to rule out the use of hazardous pesticides. Application of insecticides of botanical origin is becoming a simple and sustainable method of pest control. In this investigation Wedelia chinensis and Cymbopogan citratus were selected for mortality of scale insects. Bioactive principles in these herbs were analysed by GC-MS. Significant mortality of adult scale insects has been attributed to the presence of Butyl butyrate, Bis (3,3,5-Trimethyl hexyl) adipate in Wedelia chinensis and Benzofuran in Cymbopogan citratus in the herbal formulation.
