of newly infected trees will be quantified and rationalized to determine the rate of infection. The same calculations should be done for the control groups to ensure consistency. The way the PSHB will be assayed is by physically counting each insect after euthanasia‚ and by measuring the lengths and depths of the galleries produced by the beetles in the infected trees. Other symptoms of PSHB attack include small pencil-tip sized holes in tree bark‚ wet spots‚ and frass [1]. The amount of

The selection of the host ends when adult manage to successfully The infestation of the host is regulated by a mix of pheromones produced by both the host and the SPB (Thatcher‚ 1981; ?????‚19??).
