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.
and make contact with the insecticide. Eave tubes are potentially more effective than indoor spraying,
and land on a wall covered with insecticide, leaving them time to infect a person. ith these tubes,
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
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.
#Novel Nano-Dispenser Systems Uses Less Insecticide to Kill Citrus Greening Bugs It is a step forward in ridding groves of the insect that is threatening to destroy Florida $10. 7 billion citrus industry.
a standard insecticide used in the industry to kill the Asian citrus psyllid, among many other pests.
Using less insecticide could mean saving tens of thousands of dollars for small growers a make-or-break figure for those who are struggling with stunted production and less or no profit due to the disease. uring the past 15 years,
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

#New Material Made From 1 Billion Tiny Magnets Changes States Like Water Researchers at the Paul Scherrer Institute (PSI) announced they have created a synthetic material with magnetic properties
As an insecticide it is effective against ticks, mosquitoes or bedbugs. In the medical field, the substance has shown activity against cancer cell lines.
Two of Hinestroza students created a hooded bodysuit embedded with insecticides using metal organic framework molecules,
While insecticide-treated nets are common in African homes the antimalarial garment can be worn during the day to provide extra protection
#RNA insecticide could leave oodbugs alone An insecticide currently in development targets a specific gene
the RNA-based insecticide can be effective for at least 28 days when sprayed on a leaf.
whether an RNA-insecticide spray would be stable enough to use in agriculture. They matched double-stranded (ds) RNA to an actin gene in the Colorado potato beetle
the ds actin-RNA insecticide was highly effective on potato beetles that ate the leaves. he major problem with conventional insecticides is they affect non-target organisms,

and the stalk is placed in solution with RNA insecticide, and potato beetles ate that leaf, mortality occurred but it wasn as high.
The insecticide needs more work before it is ready to market Scott says. For example, the cost of making RNA insecticide is currently much higher than conventional insecticides.
Also, for insects need to eat sprayed leaves for it to work so insects that don eat leaves, such as houseflies,
along with current Malaria prevention techniques, like bed nets. 80%of the children involved in the clinical trials were protected also by insecticide treated bed nets.

#RNA insecticide could target specific pests A novel insecticide targets a specific gene in a pest,
a Cornell study published online in Pest Management Science describes how the RNA-based insecticide can be effective for at least 28 days
whether an RNA-insecticide spray would be stable enough to use in agriculture. The researchers matched double-stranded (ds) RNA to an actin gene in Colorado potato beetle

the manager in Scott lab. his is an insecticide that is based on a specific gene. Thus, you might be able to kill only that specific insect,
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,
