Extract

Some years ago the Entomological Department of the Swedish Forest Experiment Station was requested to undertake the investigation of the timber-destroying insects in Government buildings in Sweden. In order to obtain a preliminary survey of the amount of damage caused by these pests an illustrated leaflet containing short descriptions of the insects and their galleries was issued and, together with a detailed questionnaire and a circular letter, sent to about 7,000 persons. Altogether 2,148 reports were returned, 990 of which gave detailed information often accompanied by samples of wood for identification.
