Vic Bogosian has an 18,000-strong army--or, rather, air-force--of wasps, and he's looking for more draftees. They're fighting an enemy of the Pokagon Band of Potawatomi, the emerald ash borer, an invasive species from China that has been wiping out an important part of Michigan's Native American culture, the ash tree.

"The bugs here yet?" the...

"Students and faculty managing the Ithaca College Natural Lands are in the process of removing what they hope is the last of an invasive species of plant known as Japanese stiltgrass after six years of sustained eradication efforts. On Sept. 26, the group cleared out a majority of the remaining stiltgrass.

Mattapoisett — In 2013, at least 1,000 European flies were released into Nasketucket Bay State Reservation with the hopes that they would spread throughout the area. Awesome, right?

"It still spreads everywhere," he said, pointing to tree-sized bushes of autumn olive - plants once used for roadside stabilization but now are an invasive...

    WORCESTER - Good news on the Asian longhorned beetle front: Surveys of traps hung across Worcester County this summer have turned up only one of the pests in the city, where an infestation of the tree-killing insects was centered, and none in the region beyond.

"Most readers are familiar with monarch butterflies (Danaus plexippus). The striking orange and black species has historically been widespread throughout North America.

Its life history makes it an attractive tool for lessons about insect ecology. Monarch caterpillars forage exclusively on milkweed (Asclepias). Foul-tasting chemicals they acquire from the plants render monarch...

"The tiny seedling was brought over from Eastern Europe and parts of Asia nearly 200 years ago and planted along riverbanks across the United States, mostly in the Southwest, to prevent erosion. It grew fast, its thick branches and oily leaves spreading across five states. As years passed, it became obvious that the introduction of salt cedar, or Tamarisk trees was a mistake. The invasive tree...

In 2001, ash trees began dying in Detroit, and no one could say why. Then glittering green beetles were discovered crawling out of an ash log.

American scientists had never seen the beetles, and they reached out to experts around the world for help. A Slovakian entomologist named Eduard Jendek solved the mystery: Detroit’s ash trees were being killed by Agrilus planipennis, the emerald...
