Current projects:

• Gene silencing in emerald ash borer. My lab is evaluating the use of gene silencing as a means of suppressing emerald ash borer, Agrilus planipennis (EAB), an exotic, aggressive, tree-killing beetle that has caused the loss of millions of ash trees in urban and wildland forests. We’ve shown that RNA interference (RNAi) can cause rapid and extensive beetle mortality; we are now evaluating additional genes that, when silenced, could cause beetle mortality. Additionally, we are evaluating methods of delivery and assessing potential non-target effects.

• Gene silencing in southern pine beetle. The endemic southern pine beetle, Dendroctonus frontalis (SPB), undergoes population outbreaks that lead to landscape-scale tree mortality, and is expanding its geographic range in response to our changing climate. We have determined that SPB is susceptible to RNAi, and are working on evaluating additional genes and assessing geographic variability. We are also evaluating methods of delivery and assessing potential non-target effects.

• Invasion dynamics of emerald ash borer. We are evaluating aspects of the EAB invasion, including: 

◦ Host range expansion. Both classical biological control and chemical control can contribute to EAB management, but EAB is now colonizing a novel host, white fringetree, Chionanthus virginicus. We are investigating the implications of this novel host on the effectiveness of EAB’s classical biological control agents and on EAB invasion dynamics. 

◦ Trophic linkages. Developmental asynchrony between EAB and its classical biocontrol agents complicates implementation of an effective biological control program. Changing forest structure and composition post-invasion are creating new habitats and altering trophic interactions in unknown ways. We are assessing some of these changes. 

• Asian chestnut gall wasp and chestnut restoration. Asian chestnut gall wasp, Dryocosmus kuriphilus, is a non-native gall-forming wasp that disrupts flowering and nut production, causes physical deformities of twigs and branches, and can kill trees. We are evaluating behavioral and ecological aspects of gall wasp infestations to help minimize losses.
