Lead researcher Dr Antony Hooper of Rothamsted Research, an institute of BBSRC said: “One way in which insects find each other and their hosts is by smell, or more accurately: the detection of chemical signals – pheromones, for example. Insects smell chemicals with their antennae; the chemical actually gets into the antennae of the insect and then attaches to a protein called an odorant-binding protein, or OBP. This then leads to the insect changing its behaviour in some way in response to the smell, for example, flying towards a plant or congregating with other insects.”
Studying an OBP found in the silkworm moth Bombyx mori, Dr Hooper and his team were able to look at how the OBP and a relevant pheromone interact. They also tested the interaction between OBP and other molecules that are similar to, but not the same as, the pheromone.
Dr Hooper continued: “As well as learning about the nature of this interaction we’ve actually found that there are other compounds that bind to the OBP much more strongly than the pheromone. We could potentially apply these compounds, or similar ones, in some way to block the insects’ ability to detect chemical signals – the smell would be overwhelmed by the one we introduce. We’d expect the insects to be less likely to orientate themselves towards the crop plants, or find mates in this case, and therefore could reduce the damage.
“There is a lot of work to do from this point. We want to test this idea with important crop pests – we’ll probably start with aphids because they are a serious pest and we have some idea of what the aphid OBPs are like from the genome sequence. We’d also hope to apply our knowledge to insects such as tsetse flies and mosquitoes that carry human diseases. And ultimately we’ll look at developing ways to design suitable compounds to control these pests.”
Professor Douglas Kell, BBSRC Chief Executive said: “Around a quarter of crops are lost to pests and diseases and so if we are to have enough food in the future it is not just a matter of increasing gross yield. To secure our future food supply we must look for new and innovative ways to prevent and control pests and diseases. This is an interesting finding that could be applied across a number of important insect pests and may have far reaching implications for preventing human disease as well.”About BBSRC

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
