Invasive Gypsy Moths [LiveScience 2008-04-11]
The gypsy moth is an invasive species that destroys over a million acres of forest land every year. A new computer model may help land managers formulate more effective plans of attack against these destructive pests.
The model indicates that the best strategies for managing the moths include eradicating medium-density infestations and reducing high-density infestations, rather than reducing spreading from the main infestation.
"Most managers currently use the same strategy in all situations, but our model suggests that by tailoring their approach to a particular situation, managers can be more effective in slowing the spread of invasive species," said Katriona Shea, a biologist at Pennsylvania State University who helped design the model.
The model will be detailed the April 2008 issue of the journal Ecological Applications.
