Clove oil had a significant repellency on
adults of mite. In general, treated surface of tea leaves
discourage the movement and feeding of O. coffeae and repel
them to untreated surface (control). In the present study,
repellence effect was found to increase with increase in
concentration of clove oil. At 0.5 %concentration, repellent
percentage was recorded to be 68.54 % whereas at higher
concentration of 1 % and 1.5 %, it was 77.91 and 88.75 %,
respectively. On the treated surface of the leaves, egg laying
was significantly lower than on the control side for each
treatment. Repellent action showed that efficacy of the high
dose (1.5 %) was more than others. Clove oil at a concentration
of 0.5, 1 and 1.5 %exhibited ovicidal activity against
the eggs of O. coffeae. The egg hatchability was reduced to
86.67, 80.50 and 70.00 %at 0.5, 1 and 1.5 %concentrations,
respectively
