Increasing the concentration of neem oil from 5% to10% did
not lead to any significant change in repellent activity with a
mean repellency of 85.79 (Fig 1) as compared to 84.21 at 5%
in the previous test(24). This activity was higher than that Kinga
and 0.002% Phyrethrum extract having a mean repellency of
80.53 and 81.58 respectively (p>0.05) (Fig 1)
