The average (± s.e.m.) numbers of adult whiteflies that dispersed from a release plant to 4 neighbouring plants through time.

<p>(a) Distance between neighbouring plants 0.6 m. Predators were either released on the same plant as the whiteflies (at 0 m) or no predators were released (none). (b) Distance between neighbouring plants 2 m. Predators were either released on the same plant as the whiteflies (at 0 m), on the plant closest to the release plant (hence, at 2 m), on the same plant as the whiteflies and on the neighbouring plant (at 0 and 2 m), or no predators were released (none).
