repeated 3 times on the same day. For each fly, frequency of visit and time spent per visit in
each quadrant were recorded. The total time spent in each quadrant was calculated for all the
flies and all these values were there after expressed as a proportion of time spent in each
quadrant.The effect of essential oils C. giganteus and C. nardus on eggs deposition by B.
