Research goes on

A fungus that causes a sharp drop in forest tent caterpillar populations has the scientific name of Entomophthora megasperma. It is being studied as a potential biological pesticide at Cornell University in New York. Minnesota became tangentially involved in this research effort in April by collecting and sending over 200 egg masses to Cornell entomologists. The New York state populations of this insect had collapsed in l997, so they requested help from the Forest Health Unit.
