Abstract

Observations were carried out on adult emerald ash borers, Agrilus planipennis Fairmaire, on ash trees, Fraxinus spp., in park-like and field-edge settings in South Lyon, MI. Observations consisted of (1) counting beetles in various microhabitats; and (2) tracking behavior of individual beetles for periods of up to 15 min. Observations were made from the ground with the aid of binoculars when needed. Counts of beetles included 158 counts each of beetles per 100 leaflets, beetles seen on bark during 1-min searches, and beetles observed flying in a fixed field of view over 1 min. These counts were made systematically at different levels of the canopy (lower, middle and upper), aspects (north, south), and times of day. In addition, we made 5-min counts of beetles in the understory beneath the study trees.
