herbicide-free control of parasitic weeds in all vulnerable crops. Tóth is assistant professor at the Slovak University of Agriculture in the city of Nitra where he teaches in agricultural entomology,
through insecticide-treated bednets and indoor sprays, is one of the best ways to win the battle.
But mosquitoes are becoming resistant to insecticides potentially reversing the gains made so far. In response, the EU-funded MCD project has developed three new weapons against them a special coating that transfers insecticides effectively to mosquitoes landing on it,
insecticide-laced ave tubesto direct them to the coating, and a bednet patch. The project began work in December 2012
and is now negotiating with a manufacturer in Tanzania to mass produce these low-cost devices
This has been repurposed for mosquito control using the netting coated with insecticide at one end of tubes that are placed in the walls of the households.

insecticide is applied only to a small area the netting, he explains. his means a major reduction in insecticide use, by about 95,
%which is better for people health and for the environment. The team initially tested the eave tubes in 2013 in large outdoor cages in Tanzania.
'where the plastic with the insecticide-coated netting replaces a brick removed from a wall.
The researchers have created a piece of insecticide-treated netting, a patch that, placed on this area of the bednet, would kill 62%of the mosquitoes in the room within a night,
about the size of an A4 sheet of paper, can turn an untreated net into one that starts killing mosquitoes without the need to coat the whole bednet with insecticide.
people are less likely to come into contact with insecticide. This opens the way for more powerful alternatives to be used insecticides that remain effective against mosquitoes.
The project partners made up of three small and medium-sized European companies, a health institute in Tanzania and a US university plan to commercialise the eave tubes

#Proteins could detox pesticides and sarin gas Scientists are developing a way to prevent brain damage among people exposed to poisonous chemicals found in pesticides and chemical weapons.
The work, published in the journal Chembiochem, centers on proteins called phosphotriesterases, which degrade chemicals in a class known as organophosphates.
Organophosphates are found in everything from industrial pesticides to the sarin gas used in chemical warfare. They permanently bond to neurotransmitters in the brain,
whether through exposure to pesticide or an intentional chemical warfare attack, explains Jin Kim Montclare, associate professor of chemical and biological engineering at the New york University School of engineering. ee known that phosphotriesterases had the power to detoxify these nerve agents,
or pesticide exposure and would likely be developed first for military use, these proteins also could be critical
#Use microbes, not pesticides, to boost crop yields Iowa State university Original Studyposted by Fred Love-Iowa State on September 9 2013.
The recommendations published in the Academy s Colloquium Reports set a goal of increasing yields by 20 percent over the next 20 years by enhancing the use of microbes while reducing the use of pesticides and fertilizers by 20 percent.

#Explosives and Pesticides Can Be detected by Using Bee venom Scientists from MIT have discovered that by coating carbon nanotubes in bee venom,
as well as at least two different types of pesticides. This means that bees and their stingers could become important to making better environmental sensors.
But the sensors aren just useful for explosives the researchers found that the coated nanotubes can also detect two pesticides that contain nitro-aromatic compounds.
especially after we recently saw that scorpion venom can be used to create pesticides. Strano has filed for a patent on the sensor,
The crisis is attributed generally to a mixture of disease, parasites, and pesticides. Other scientists are pursuing a different tack:

As a result the mosquitoes were more prone to insecticides as they no longer had a sufficient amount of chitin for a normal functioning protective shell.
If the production of chitin can be reduced further the insects can be killed without using any toxic insecticides.

Using insecticides is one of the few ways farmers currently have to treat their groves for greening, also known as Huanglongbing or HLB.
Although current methods to control the spread of citrus greening are limited to the removal and destruction of infected trees and insecticide-based management of psyllid populations
Researchers also said that less insecticide could have beneficial environmental impacts. Further field tests are necessary to see how the nano-dispensers perform in sunlight

#RNA insecticide could target specific pests A novel insecticide targets a specific gene in a pest,

and the stalk is placed in solution with RNA insecticide, and potato beetles ate that leaf, mortality occurred but it wasn as high.
Before such an insecticide is ready for market, it needs more work, Scott said. For example, the cost of making RNA insecticide is currently much higher than conventional insecticides.
Also for the insecticide to work, insects need to eat the leaf, which means the spray will not affect insects that don eat leaves, such as houseflies,
or those that suck sap, such as aphids. Also, some insects are unaffected simply, perhaps due to gut enzymes that break down the ds RNA. he technology is really at its infancy,
