Abstract
Laboratory experiment was conducted to evaluate the bioefficacy of ethnobotanical plant Lippia javanica at Entomology laboratory at IFB, Hyderabad during 2016-2018. Experiment was carried out in Completely Randomized Design and antifeedant activity and toxicity was observed in the plant extracts based on the feeding behavior of the test insect and arranged in the descending order is 1.0%>0.8%>0.6%>0.4%>0.2%>0.1% concentrations and uncontrol. The insect culture was maintained in a growth chamber in the laboratory at a temperature of 27 ± 2°C, 12: 12 L:D and with 70 ± 5 % RH during the experiments. Hence depending upon the pest problem, a particular type of extract has to be applied for effective control of the pest.
