The Giant Willow Aphid (GWA) populations have been monitored monthly on a group of 20 willow trees in the Matokitoki Valley since the last conference.  Special attention has been given to monthly sticky band captures of various life stages on two of the trees.  In addition, patterns of GWA movements have been observed, especially around fence lines.  We have a new insect visitor on our willows in recent months which will be described.
