Entomologists play matchmakers for cerambycid beetles Aug 6, 2008
"Before our project, little was known about the chemical ecology of cerambycid beetles or their use of attractant pheromones, and the pheromones of only a few species had been identified," Millar said. "Our longer-term goals are to gain a better understanding of which subfamilies, tribes, and genera are likely to use pheromones, and, within those groups, to determine the types of chemicals that are used as pheromones. This will allow us to predict whether new invaders are likely to use... (EurekAlert!)
No Scent, No Sex For The Japanese Beetle Jun 27, 2008

OSU scientists say bugs could have helped doom dinosaurs Sep 11, 2007
" George Poinar said bugs likely were just one factor. Climate change, ocean regressions and volcanic activity may have contributed, he said. Even 100 million years ago, bugs were pests. Poinar studied bugs trapped in amber that bore diseases and even pathogens from cold-blooded vertebrates, some of them probably dinosaurs, he said. He said insects also would have competed for the same plant food and led to the rise of flowering plants, which pushed aside species such as ferns that some... (KGW Northwest NewsChannel 8, OR)
