We've also been spreading pests and diseases from place to place often causing local extinctions.

A 2010 survey from the University of Kentucky and the National Pest Management Association found that 95%of US pest control companies had treated a bed bug infestation in the previous year

According to the survey, the majority of pest control operators from Europe, Africa, Australia and North america said bed bugs were the most difficult insect pest to control, more so than ants, termites and even the formidable cockroach.

a pest management consultant in Suffolk and author of the London survey, says that UK bedbug numbers began decreasing in the 1930s, thanks to changes in social housing and public health policies,

Still, chemicals and other tactics can be used in an integrated pest management strategy, where they are used sometimes sparingly along with heat treatments (bed bugs die at 45c), desiccants such as silica gel and diatomaceous earth that fatally dry the bugs out,

Officially known as the brown marmorated stink bug, sightings of the pest have been reported in 33 states, an increase of eight states since last fall.

video) I would say people now regard them as an out-of-control pest, #says Kim Hoelmer, a research entomologist at the U s. Department of agriculture in Newark, Del.

The National Pest Management Association warns homeowners this week that the bugs growing populations are likely to make infestations significantly worse this year.

Rosenthal says a report of a stink bug in a state does not necessarily mean that the pest is established

Some of these are agricultural pests, while others are beneficial predators that feed on insects#but now its just the brown marmorated one in the USA thats causing all the fuss.

#USDA officials take this pest seriously and are hard at work trying to understand effective ways to control it

because pests dont eat it #or die if they do. Even simply soaking cassava for a few hours will help as it also contains an enzyme called limnarase that liberates the cyanide over time.

By contrast populations of these pests used to be thinned and thereby neutralized by the killing cold of winter.

Brown is among a growing number of farmers who use a suite of techniques to build soil's natural capacity to retain moisture discourage weeds and pests and nurture crops.

The GMO crops that are used widely have for the most part been engineered genetically to control pests in one of two ways:

GMO crops that are modified with the Bt gene have a proven resistance to insect pests thus reducing the need for wide-scale spraying of synthetic pesticides.

In addition to pest resistance GMO crops can be engineered for disease resistance drought tolerance added nutrients hot or cold temperature resistance and other beneficial traits.

Potatoes engineered with a lectin gene (for resistance to pests) were linked to stomach damage in rats that consumed the potatoes according to a report from the University of California Davis

Many bats are on nighttime pest patrol. One Mexican free-tailed bat can eat about 1000 mosquitoes per hour.

Just 150 big brown bats can eat 33 million root worm pests. Without bats there would be more pests

and crops would suffer from more pest damage. Other bat species feed on flowers and fruits acting act as pollinators and seed dispersers especially in deserts and rain forests.

Bats pollinate wild bananas the famous saguaro cactus and durian the world's most expensive fruit.

Globally insect agricultural pests reduce crop yields by 10 percent to 14 percent and damage 9 percent to 20 percent of stored food crops.

Farmers primarily use chemical insecticides to control pests but many insects are resistant to them.

and many insects (including pests such as bark beetles in the West or gypsy moths in the East) reproduce more quickly and often.

Considered pests the creatures tend to flock to cities where they weaken and in some cases kill trees by sucking out their sap.

The pests threaten to become a bigger problem as climate change drives temperatures up researchers warn.

We now have a better understanding of why trees in urban areas are infested by so many of these pests study researcher Steve Frank an assistant professor of entomology at North carolina State university said in a statement.

For example better storage facilities on farms in Africa and even putting harvested crops in plastic storage bags would reduce the amount of food that falls victim to pests there Hanson said.

Many of the creatures with expanded ranges are invasive pests like the emerald ash borer (Agrilus planipennis) and the hemlock wooly adelgid (Adelges tsugae) both

But not all pests are adapted so well to winter: Populations of hemlock wooly adelgids which kill evergreens by feeding on the plants'needles year-round are expected to plummet.

Other vulnerable pests include the southern pine beetle (Dendroctonus frontalis) the brown marmorated stinkbug (Halyomorpha halys) and ticks (Ixodes sp.

Pests could overcome GM cotton toxins: Nature Newslaboratory studies suggest that it may be possible for insects to overcome two disparate toxins produced by genetically modified cotton.

and create crops that produce multiple toxins that target the same pest. This is the current trend of all the companies,

The researchers were studying pink bollworm (Pectinophora gossypiella) a particular nuisance in the cotton fields of the southern United states. Crops expressing Cry1ac have held thus far largely the pest at bay,

GM crop lures pest killers: Nature Newsresearchers have created transgenic maize plants that fight off pests by emitting a chemical to attract insect-killing nematode worms. 1the method,

demonstrated in agricultural field trials at the University of Missouri's Bradford Research and Extension Center in Columbia, could help farmers to control crop pests by luring natural parasites or predators.

This could avoid the problems associated with synthetic pesticides, which can damage ecosystems and tend to lose their impact as pests acquire resistance.

European and US researchers, headed by Theodoor Turlings, a chemical ecologist from the University of Neuch Â¢tel in Switzerland

whose larvae are major maize pests in North america. This mimics the natural defensive strategies of many plants,

which release volatile organic compounds to attract pest enemies when their tissues are damaged. Many maize varieties already contain a gene to make this compound.

the study shows that it is possible to enhance biological pest control. People have been thinking about this method of pest control for a very long time,

he says. The main problem is that researchers don't know the key compounds to target in most plants.

And the approach could be combined with other transgenic pest control methods such as using genetically modified crops that carry toxins.

Guy Poppy, a chemical ecologist from the University of Southampton, UK, agrees that the method should allow farmers to reduce crop damage without eradicating the entire population of pests in a field's ecosystem-allowing biodiversity to remain mostly unchanged.

His team's next step is to work out ways of making plants emit the compound only when under attack by pests.

including rotating strawberries with crops such as broccoli that contain natural pest deterrents, or using steam to fumigate soils.

and pine tree species should help forest managers design better pest-control tactics, the authors say.

The situation was exacerbated by an early misidentification of the caterpillar as an armyworm (a devastating crop pest that regularly attacks eastern Africa,

which are engineered to produce pest-killing toxins from the bacterium Bacillus thuringiensis, use less insecticide. Increased planting of herbicide-tolerant crops may also have reduced the use of many herbicides that linger in soil and waterways

Pest resistance is a really promising and important application for genetic selection because there are a lot of health problems in developing countries that have been linked to the spraying of pesticides.

GM crop use makes minor pests major problem: Nature Newsgrowing cotton that has been modified genetically to poison its main pest can lead to a boom in the numbers of other insects,

a ten-year study in northern China has found. In 1997, the Chinese government approved the commercial cultivation of cotton plants genetically modified to produce a toxin from the bacteria Bacillus thuringiensis (Bt) that is deadly to the bollworm Helicoverpa armigera.

an entomologist at the Chinese Academy of Agricultural Sciences in Beijing, has monitored pest populations at 38 locations in northern China,

Numbers of mirid bugs (insects of the Miridae family), previously only minor pests in northern China, have increased 12-fold since 1997,

Mirids are now a main pest in the region, says Wu. Their rise in abundance is associated with the scale of Bt cotton cultivation.

The team attributed this to increased pesticide use to deal with secondary pests. The conclusion was controversial,

an entomologist at the University of Minnesota in St paul. The finding reminds us yet again that genetic modified crops are not a magic bullet for pest control,

They have to be integrated part of an pest-management system to retain long-term benefits. Whenever a primary pest is targeted,

other species are likely to rise in its place. For example, the boll weevil was once the main worldwide threat to cotton.

bollworms developed resistance and rose to become the primary pest. Similarly, stink bugs have replaced bollworms as the primary pest in southeastern United states

since Bt cotton was introduced. Along with genetically modified crops, says Andow, farmers need effective systems for responding to changes in pest abundance.

This needs to be based on research into the timing dosage and frequency of pesticide use needed to tackle new pests.

When farmers decide how to control pests, they tend to overuse pesticides, he says. Wu and his colleagues are seeking the most effective way to use pesticide,

and trying to reduce mirid damage to cotton by growing crops the pests prefer nearby.

Meanwhile, Chinese researchers are trying to develop cotton plants that kill both bollworms and mirids. Wu stresses,

however, that pest control must keep sight of the whole ecosystem. The impact of genetically modified crops must be assessed on the landscape level,
