The Effect of Artificial Defoliation on the Growth of Pinus Kesiya and Pinus Oocarpa in Zambia
The results of this experiment, where insect defoliation was simulated by artificial defoliation, suggest that Pinus kesiya and P. oocarpa trees in Zambia survive after complete defoliation, and that the reduction in growth may remain economically tolerable.
