Dr. Maier’s research specialty is the ecology and the management of exotic fruit and forest pests.  He is an expert on the biological control and host preferences of leafminers and leafrollers that damage fruit trees and on the detection and host preferences of wood-boring beetles that injure trees and shrubs.

Past research:
Orchardists, foresters, and landscapers face many challenges as they attempt to manage insect pests with minimal use of insecticides.  Research conducted by Dr. Maier has focused on the biological control, the host preferences, and the pheromone communication of leafminers and leafrollers in fruit orchards.  He has investigated methods for detecting and sampling forest insects, especially wood-borers and defoliators.  He also has studied the distribution, host preferences, and damage of new foreign pests recently discovered in Connecticut forests. In 2004, he and his coworkers completed a color identification guide to caterpillars on coniferous trees; a revised edition of this guide will be published in August 2011.

Current research:
Dr. Maier is studying the detection, biology, distribution, and host preferences of several invasive orchard and forest insects.  In orchards, he is investigating the biological control of apple leafminers, the distribution and damage of the brown marmorated stink bug, and new trapping techniques for insects. In forests, he is conducting research on improved trapping methods, host preferences, and seasonal activity of wood-boring beetles, particularly longhorned beetles or Cerambycidae.  He routinely oversees detection surveys for exotic insects that may or do occur in Connecticut.

Dr. Maier is a member of the Entomological Society of America, the Entomological Society of Canada, the Entomological Society of Washington, and the Coleopterists’ Society.  He has been President of the Connecticut Entomological Society three times.  He currently serves on the Cooperative Agricultural Pest Survey Advisory Committee and on the Invertebrate Subcommittee of Connecticut ’s Endangered Species Committee.  He is a Curatorial Affiliate of the Yale Peabody Museum.
