The test samples were found to have effective ovicidal activity as illustrated in Table 4. In case of FE, the ovicidal activity was revealed from EC50–EC90 values of 18.82–69.61 lg/ml. Other fractions (HT and NC) were equally effective with EC50–EC90 values of 19.97–75.80 lg/ml for HT and 19.88–73.72 lg/ml for NC. The figures have indicated the potential toxicity of all the three samples on eggs of A. albopictus.
