Eight species of rhabditoid nematodes were tested for their ability to kill and reproduce in A. For instance, shade-tolerant shrubs, flowers, groundcovers, and vines that once thrived in canopied yards will face much stronger summer sun and may not survive. Rhabditoid nematodes have been used successfully as microbial insecticides in control programs for other cryptic pests such as lawn grubs.

Entomopathogenic bacteria have been isolated from ALB larvae and pupae, and a baculovirus has been isolated from A. Reciprocal investigations have only recently been initiated within the U. Eventually, the structural insecurity caused by larval ALB feeding prevents the tree from sustaining itself, causing death. Research efforts include developing: The City of Shaker Heights has established 3 test sites, each comprised of 13 maple trees, which are regularly monitored for any signs of ALB. What is the value of a tree in the city?
