Mediterranean Pine Engraver for Eastern Forests
The Mediterranean pine engraver is new to the United States. It was first detected here in 2004. This bark beetle has a history of causing extensive mortality in pines elsewhere in the world, but it is uncertain whether the beetle could feed on conifers in the northeastern United States. Information is needed to better predict and prevent the spread of the beetle to the rest of the country.
We are studying the Mediterranean pine engraver in California where the beetle has established and in a quarantine laboratory operated by the Minnesota Department of Agriculture/Minnesota Agricultural Experiment Station. Our research attempts to determine whether the bark beetle will recognize and attack conifers from the northeastern United States, to identify tree species that can support the reproduction of the beetle, to identify vulnerable geographic regions where the beetle is likely to establish, to determine how far the beetle can disperse, and to design strategies to detect infestations of the beetle with a new attractant.
The goal of our research is to provide tools and strategies to efficiently detect small populations of the Mediterranean pine engraver and protect conifers from the effects of this insect.
