摘要:

Artificially inoculated spider mite foci increase in size at an exponential rate. Productivity was greatest on plants farthest from the center of each focus. Timing of initial infestation was shown, both experimentally and through simulation, to affect ultimate yield of cotton: the earlier the initiation of infestation, the lower the yield. These results as well as those of other researchers indicate that the tolerance of cotton to mite infestations increases with crop maturity.
