A new approach The fate of much of the world's wildlife is playing out in human-altered landscapes that are threatened increasingly by chemical inputs such as herbicides and pesticides.
and Europe--parasites pathogens and pesticides--do not seem to be affecting Kenyan bees at least not yet said Christina Grozinger professor of entomology and director of the Center for Pollinator Research Penn State.
and measure pesticide contaminants in hives and determine the genetic composition of the colonies. This is the first comprehensive survey of bee health in East Africa where we have examined diseases genetics
At all of the sites they found only a small number of pesticides at low concentrations.
In addition the researchers suggest that beekeepers use pesticides sparingly. This research is important because it confirms the resilience of African bees
and it suggests that the approach to manage these pests should not follow the application of pesticides as has been done in the western world said Muli.
As these new parasites and pathogens become more widespread as pesticide use increases and as landscape degradation increases due to increased urbanization farming and climate change we expect to see the combination of all these factors negatively impact the bees in the future Grozinger said.

and in many cases their wives too taking their own lives by drinking the modern pesticides designed to provide them with bountiful harvests--a truly horrific end as the chemicals cause swift muscle and breathing paralysis. Added Kennedy:
This could be due to the fact that in Adã lie Land the more severe environmental conditions combined with the increasing presence of other pollutants (pesticides PCBS) magnify the impact of mercury contamination.
In addition they are carrying out similar studies to measure the effects on bird populations of'conventional'pollutants such as pesticides

#Pesticides make the life of earthworms miserablepesticides are sprayed on crops to help them grow but the effect on earthworms living in the soil under the plants is devastating new research reveals:
Pesticides have a direct impact on the physiology and behavior of earthworms a Danish/French research team reports after having studied earthworms that were exposed to pesticides over generations.
We see that the worms have developed methods to detoxify themselves so that they can live in soil sprayed with fungicide.
They spend a lot of energy on detoxifying and that comes with a cost: The worms do not reach the same size as other worms
because they spend their energy on ridding themselves of the pesticide the researchers Ph d. student Nicolas Givaudan
They moved two portions of farmed soil with worms into the lab. One portion was taken from a local organic field the other from a local conventionally cultivated field that had been sprayed with fungicide for 20 years.
This soil had remnants of the internationally commonly used fungicide Opusâ at a level common in fields.
When crops are sprayed with fungicide only a small part of the chemical is absorbed by the plant.
The waste can be up to 70 per cent and much of the fungicide ends up in the soil.
In the laboratory the researchers could see how the fungicide-exposed worms adapted to the toxic environment.
The fungicide increased metabolism rate in the worms both the adapted worms and the not adapted worms.
and found that the worms exposed to fungicide weighed only half of the worms in organic soil.
and apply fungicides to fight the disease. This disease is not new Yen says. It was reported first in England in 1884 and in North america in 1890.
Loss of natural habitat changes in land use pesticides the potential for bird diseases and even climate change have all been mentioned
The study is reported in the journal Pesticide Biochemistry and Physiology. Our results indicate that the effectiveness of RNAI treatments could potentially vary among field populations depending on their genetic and physiological backgrounds the researchers wrote.
Synthetic pesticides are toxic and expensive. Moreover pesticides usually do not actually kill the nematodes they just temporarily paralyze them.
Nematodes can also build up resistance to pesticides. We have wondered always how the Yangambi km5 fights off roundworms.
This study offers an answer. While the Grande Naine is very susceptible to nematodes other varieties are known to be resistant to them.
Our findings also provide the industry with perspectives to develop a generation of new pesticides against nematodes.
BEEHAVE can also be used to investigate potential consequences of pesticide applications. For example the BEEHAVE model can simulate the impact of increased loss of foragers.
The use of this model by a variety of stakeholders could stimulate the development of new approaches to bee management pesticide risk assessment and landscape management.
pesticidesresistance to pesticides has now been recorded in nearly a thousand pest species including more than 500 insects 218 weeds and 190 fungi that attack plants.
The recorded cases of resistance in insects mites and other arthropods which include resistance to multiple pesticides per species more than doubled from 5141 in 1990 to 11254 in 2013.

so that any negative impacts the psyllid bacterium disease or pesticide use are having on the plant can translate into improved yields.
or the pathogen and any nutrient imbalances that result or any phytotoxicity that might occur after applying pesticides French said.
but also because different countries have different standards about pesticides and using antibiotics in hives to keep the bees disease-free.
Other than using synthetic pesticides there have been few alternative approaches to controlling these pests. By identifying the major protein components of saliva it now may be possible to target the specific factors in saliva that are essential for their feeding and therefore design new approaches for controlling stink bugs.
and is considered a much preferable alternative to spraying pesticides over urban or suburban areas near major ports.
Currently insect pests are managed with pesticides and synthetic pheromones--the latter of which confuse the insect and prevent it from breeding

By also applying the pheromone that female beetles use to attract males we can trick the male beetles into going to the deadly fungicide rather than to a fertile female.
farmers can lose more than 0. 35 tonnes per hectare in wheat yields to Yellow Spot even after applying fungicide.
and would be a real win for farmers--they will often be able to avoid using foliar fungicides Professor Oliver said.
Many scientists have proposed new drivers such as pollution from pesticides as the cause of these declines.
These types of studies continue to advance the safety of biological control for suppressing populations of invasive pests thereby greatly reducing reliance on pesticides for control said Hoddle a biological control specialist in the Department of Entomology.
In urban areas initially pesticide treatments were applied to ACP-infested trees and chemically-treated buffer zones were established around sites to control the pest.
and the adoption of transgenic Bt (Bacillus thuringiensis cotton which is modified to express its own pesticide the researchers found that the value of the pest control services dropped 79 percent from a high of $23. 96 million in 1990
and pesticides that replace nature's services such as pollination and natural pest control diminish the importance of protecting ecosystems said LÃ pez-Hoffman
because the biodiversity benefits of each organic farm will be diluted in clusters of organic farms compared to an organic island providing rich habitats in a sea of pesticide-covered conventional fields.
and could be affected by pesticides there.''The impact of organic farming on total species richness varied significantly across the data with the average gain in species richness varying between 26%and 43%.
''Some conventional farms will intensively spray pesticides and fertilisers whereas others will use mixed methods of crop rotation
and organic fertilisers with minimal chemical pesticides'said Dr Turnbull.''There are also regional differences in farming practices
#Pesticides increase risk for Parkinsons disease: Certain people may be more susceptibleprevious studies have shown the certain pesticides can increase the risk for developing Parkinson's disease.
Now UCLA researchers have now found that the strength of that risk depends on an individual's genetic makeup
which in the most pesticide-exposed populations could increase the chances of developing the debilitating disease by two-to sixfold.
and the pesticide benomyl a fungicide that has been banned by the U s. Environmental protection agency. That study found that benomyl inhibited an enzyme called aldehyde dehydrogenase (ALDH)
In this study UCLA researchers tested a number of other pesticides and found 11 that also inhibit ALDH
and director of movement disorders at UCLA. Bronstein said the team also found that people with a common genetic variant of the ALDH2 gene are particularly sensitive to the effects of ALDH-inhibiting pesticides
and were two to six times more likely to develop Parkinson's than those without the variant when exposed to these pesticides.
We were surprised very that so many pesticides inhibited ALDH and at quite low concentrations concentrations that were way below
what was needed for the pesticides to do their job Bronstein said. These pesticides are pretty ubiquitous
and can be found on our food supply and are used in parks and golf courses and in pest control inside buildings and homes.
Researchers focused their analyses on individuals with ambient exposures to pesticides at work and at home using information from the California Department of Pesticide Regulation.
Exposure to pesticides starts a cascade of cellular events preventing ALDH from keeping a lid on DOPAL a toxin that naturally occurs in the brain.
In this study the research team developed a lab test to determine which pesticides inhibited ALDH.
Then the researchers found that those participants in the epidemiologic study with a genetic variant in the ALDH gene were increased at risk of Parkinson's when exposed to these pesticides.
This report provides evidence for the relevance of ALDH inhibition in Parkinson's disease pathogenesis identifies pesticides that should be avoided to reduce the risk of developing Parkinson's disease

#DDT pesticide exposure linked to Alzheimers disease, study showsscientists have known for more than 40 years that the synthetic pesticide DDT is harmful to bird habitats and a threat to the environment.
Now researchers at Rutgers University say exposure to DDT--banned in the United states since 1972 but still used as a pesticide in other countries--may also increase the risk and severity of Alzheimer's disease in some people particularly those over the age of 60.
In a study published online today in JAMA Neurology Rutgers scientists discuss their findings in which levels of DDE the chemical compound left
and livestock and to combat insect-borne diseases like malaria--was introduced as a pesticide during WWII.
Although the levels of DDT and DDE have decreased significantly in the United states over the last three decades the toxic pesticide is still found in 75 to 80 percent of the blood samples collected from the Centers for Disease Control and Prevention.
In addition people may be exposed to the pesticide by consuming imported fruits vegetables and grains where DDT is still being used
#Common crop pesticides kill honeybee larvae in the hivefour pesticides commonly used on crops to kill insects
or inactive chemical commonly used as a pesticide additive--is highly toxic to honeybee larvae.
We found that four of the pesticides most commonly found in beehives kill bee larvae said Jim Frazier professor of entomology Penn State.
We also found that the negative effects of these pesticides are sometimes greater when the pesticides occur in combinations within the hive.
Since pesticide safety is judged almost entirely on adult honeybee sensitivity to individual pesticides and also does not consider mixtures of pesticides the risk assessment process that the Environmental protection agency uses should be changed.
According to Frazier the team's previous research demonstrated that forager bees bring back to the hive an average of six different pesticides on the pollen they collect.
Nurse bees use this pollen to make beebread which they then feed to honeybee larvae.
To examine the effects of four common pesticides--fluvalinate coumaphos chlorothalonil and chlorpyrifos--on bee larvae the researchers reared honeybee larvae in their laboratory.
They then applied the pesticides alone and in all combinations to the beebread to determine
whether these insecticides and fungicides act alone or in concert to create a toxic environment for honeybee growth and development.
The researchers also investigated the effects of NMP on honeybee larvae by adding seven concentrations of the chemical to a pollen-derived royal jelly diet.
NMP is used to dissolve pesticides into formulations that then allow the active ingredients to spread
We found that mixtures of pesticides can have greater consequences forlarval toxicity than one would expect from individual pesticides Frazier said.
Among the four pesticides honeybee larvae were most sensitive to chlorothalonil. They also were affected negatively by a mixture of chlorothalonil with fluvalinate.
According to Chris Mullin professor of entomology Penn State these pesticides may directly poison honeybee larvae
Chronic exposure to pesticides during the early life stage of honeybees may contribute to their inadequate nutrition
Chlorothalonil is a broad-spectrum agricultural fungicide that is often applied to crops in bloom when honeybees are present for pollination
Our findings suggest that the common pesticides chlorothalonil fluvalinate coumaphos and chloropyrifos individually or in mixtures have statistically significant impacts on honeybee larval survivorship Mullin said.
This is the first study to report serious toxic effects on developing honeybee larvae of dietary pesticides at concentrations that currently occur in hives.
There is a growing body of research that has reported a wide range of adverse effects of inactive ingredients to human health including enhancing pesticide toxicities across the nervous cardiovascular respiratory
Multi-billion pounds of these inactive ingredients overwhelm the total chemical burden from the active pesticide drug
There has been a heavy reliance on fungicides to control disease but some of the most effective fungicides are now being withdrawn through EU regulations.
So there is a need to develop oilseed crop varieties with greater inbuilt resistance to the disease.
Plots sprayed with fungicide soon become dominated by a few species at the expense of many others leading to a marked drop in diversity.'
Researchers sprayed plots with water insecticide or fungicide every week for 17 months. They found that the fungicide Amistarâ dealt a significant blow to diversity reducing the effective number of species by 16%.
%While the insecticide did change the composition of surviving species it did not have an overall impact on diversity.'
No magic bullet for coffee rust eradicationspraying fungicide to kill coffee rust disease which has ravaged Latin american plantations

The techniques of so-called modernization (e g. cutting shade applying fungicides) may gradually eliminate what has been effectively autonomous biological control of coffee rust.
and applying fungicide is one of the main control methods promoted in the affected countries.
But generalized fungicides can also kill the white halo fungus which is known to attack coffee rust.
#Exposure to pesticides results in smaller worker beesexposure to a widely used pesticide causes worker bumblebees to grow less
The research published today in the Journal of Applied Ecology reveals that prolonged exposure to a pyrethroid pesticide
The researchers Gemma Baron Dr Nigel Raine and Professor Mark Brown from the School of Biological sciences at Royal Holloway worked with colonies of bumblebees in their laboratory and exposed half of them to the pesticide.
Our result revealing that this pesticide causes bees to hatch out at a smaller size is of concern as the size of workers produced in the field is likely to be a key component of colony success with smaller bees being less efficient at collecting nectar
The study is the first to examine the impact of pyrethroid pesticides across the entire lifecycle of bumblebees.
Given the current EU moratorium on the use of three neonicotinoid pesticides the use of other classes of pesticide including pyrethroids is likely to increase.
Our work provides a significant step forward in understanding the detrimental impact of pesticides other than neonicotinoids on wild bees.
