Droughts, insect invasions, fires and storms would cause widespread forest destruction. The impacts of these fires and pest infestations will lead to an additional release of carbon into the atmosphere,
the short-term positive impacts would be cancelled out by damage from increased insect invasions, fires and storms.
says Allan Carroll, an insect ecologist with the Canadian Forest Service in Victoria, British columbia. By 2020, the projected end of the outbreak, about 270 megatonnes of carbon will have been emitted to the atmosphere3.
To date, fire-prevention policies in regions such as western North america have sought to suppress forest fires altogether leaving forests more susceptible to large-scale fires and insect attack.
resistant to a variety of insects and diseases and able to withstand the vagaries of climate change,
Nature Newslaboratory studies suggest that it may be possible for insects to overcome two disparate toxins produced by genetically modified cotton.
Insects can become resistant to individual insecticides in much the same way as bacteria develop resistance to antibiotics.
Missouri, intends to launch a line of maize (corn) that contains eight different genes that make the crop resistant to herbicides and to attack by insects.
The main way that insects become resistant is by altering the binding site of the toxin,
if the insects altered the Cry1ac binding site, it's not going to give cross resistance to Cry2ab.
But when Tabashnik and his colleagues tried to selectively breed insects that were resistant to Cry2ab
and there has been no sign of Cry1ac resistance emerging in the insects. Tabashnik wanted to learn more about how insects may become resistant to the less-studied Cry2ab protein,
so the team raised a number of different laboratory strains of pink bollworms on a diet that contained the toxin.
both toxins are activated via the same pathway in the insect. A change in the protease responsible for activating the toxins could provide an avenue to cross-resistance,
Other changes in the insect's ability to cope with damaged cells could also play a part,
But this does not pose a threat for control by the current pyramided Bt cotton of this insect Tabashnik says.
Evolution by insects is not something that scientists are going to stop.

The little grey insects are among the world's most notorious agricultural pests: their larvae are the pink bollworms (Pectinophora gossypiella), also known as'pinkies'.
Sterile insect releases have already been used to drive down populations of the Mediterranean fruit fly, or Medfly, in Guatemala, Mexico and the United states;
it's kind of hard to release enough sterile insects to do any good, says Fred Gould, an entomologist at North carolina State university in Raleigh,
Unfortunately sterile-insect release plans require extensive resources, Hutchison cautions. Plans to eliminate the pink bollworm from the United states and northern Mexico cost $30 million a year between 2006 and 2009.

Next, the team placed the insects into an arena with petunias (Petunia integrifolia) and measured the flowers'electrical potentials.

The insects often meet in urban or agricultural areas, where neonicotinoids are in use. So ecologist Rafael Barbieri, a graduate student in the lab of Philip Lester at Victoria University of Wellington, wondered
