Biological Control of Weevils (Strophosoma melanogrammum and S. capitatum) in Greenery Plantations in Denmark

Abstract
The project aimed at developing biological control of weevils (Strophosoma melanogrammum and S. capitatum) that cause damage to fir in Danish greenery plantations (Abies nobilis). Insect pathogenic fungi were tested in the laboratory and applied in a plantation, in which the life cycle of the weevils was also studied. Metarhizium anisopliae showed a significant effect, which - due to the long life cycle of the weevils (approx. 16 months) - could be documented in the year after application. It is concluded that it is possible to develop biological control of weevils for practical use.

The Danish Environmental Protection Agency will, when opportunity offers, publish reports and contributions relating to environmental research and development projects financed via the Danish EPA.

Please note that publication does not signify that the contents of the reports necessarily reflect the views of the Danish EPA.

The reports are, however, published because the Danish EPA finds that the studies represent a valuable contribution to the debate on environmental policy in Denmark.
