Are changes inevitable for current IPM practices? Several recent papers unquestionably avow that IPM change is in the wind that is drifting, albeit slowly and unevenly, across the entire globe.

When a natural disaster strikes, the last thing that most people are worried about is what animal or plant species might be carried to another country. But those new species are just what scientists are discovering from a dock ripped away by the tsunami that hit the northern coast of Japan last year.

Wait, you’re thinking; this is an integrated pest management blog, not an FBI blog, right? Yes. For those of you who have never heard the term “geographic profiling,” it refers to a method used by crime fighters to track down serial killers, especially when they have a large pool of suspects. According to a group of scientists in Britain, who published a paper in the journal Ecography, scientists trying to stop the spread of invaders–invasive species, that is–can use the same tool to locate source populations of those invasive species, with considerably less effort than they may be using with many of the current source locator methods.

Although the cost of invasive species has not sparked nearly as much debate as has the possibility of global warming, the combination of the two has bred some interesting research. In New Zealand, for example, a group of scientists recently examined what effect warming temperatures would have on the invasive Argentine ant, and whether native ant populations could recover if invasive ant colonies disappeared.

Even if you’ve never heard the term ‘invasive species’, chances are they’ve affected you in one way or another. Invasives are any non-native species or organism that cause harm to a non-native environment. For example, you may have heard about the brown marmorated stink bug, introduced accidentally into Pennsylvania from Asia, which has descended on towns along the east coast. With no natural predators, the insects are able to multiply, feeding on a wide variety of fruits and vegetables, hurting farmers and their crops.

The forest may be home to several species of house ants, but one of those species is finding the slick life of the city to be much more appealing. According to a recent study at Purdue University, the odorous house ant (Tapinoma sessile) is not only thriving in urban areas; it’s actually taking over.

In a small niche of the forests of China, Korea and Japan, the Asian longhorned beetle evolved unnoticed. A hardwood tree pest with a black and white specked abdomen and long antennae, it survived in a pocket of hardwood trees amidst a largely evergreen Asian forest. Because the longhorned beetle feeds on the heartwood of hardwood trees only, the beetles’ populations remained low.

USA Today‘s Marty Roney writes about cogongrass in today’s article Weeds threaten wildlife and create fire hazard in Deep South. Note the classic invasive species attributes of this story: introduced unwittingly, no natural controls in the new habitat, displacement and disruption.
