Research focuses on lipid metabolism and signalling, in particular on the mechanism and roles of lipid catabolism and the impact of these processes on plant physiology and lipid engineering.
Biological Chemistry and Crop Protection
The poster Resistance to pyrethroids in Varroa destructor is to be presented at The Seventh International Symposium on Molecular Insect Science.
Analysis of samples from a 160-year-old experiment at Rothamsted Research reveals the re-emergence of an ancient gene due to modern agricultural practices.
Pests and diseases can develop resistance to chemicals used for crop protection, and this poses a major challenge for future food security. The phenomenon of resistance is not unique to agriculture – the issue of drug resistance by microbiotic organisms poses serious challenges for human health also.
Scientists call for evidence-driven debate
An international panel of scientists including Professor Lin Field from Rothamsted Research, which receives strategic funding from the BBSRC, is today calling for an evidence-driven debate over whether a widely used type of insecticide is to blame for declines in bees and other insect pollinators.

Smallholder farmers growing wheat crops in southern Africa face losing up to half of their wheat yields to aphids. Pesticides that could prevent such attacks are often too expensive, but scientists are screening wheat lines to look for a new, cheaper way to protect African wheat from aphids. The scientists hope to identify resistance to two major aphid pests and breed the trait into wheat suitable for African climates.
UK farmers are currently facing a huge problem which undermines the viability of their businesses and their economic competitiveness: the pests, weeds and diseases that attack their crops are becoming pesticide-resistant. Our farmers don’t have enough tools in the toolkit to stop their harvests from being destroyed. Developing sustainable crop protection was already a major issue for the industry, but now with uncertainties regarding farm incomes after Brexit it is all the more critical.
This is a special announcement regarding the diamondback moth and covers observations up until the 10th June 2016. Diamondback moths are an important migratory pest of brassicas, causing feeding and cosmetic damage that can lead to severe losses in cruciferous crops. The diamondback moth (Plutella xylostella) is a species often described a 'super-pest' because they have been found to be resistant to most insecticides, including pyrethroids and diamide.
To control levels of the parasitic mite varroa within hives, many beekeepers use the chemical tau-fluvalinate, marketed as Apistan®, but its effectiveness has been decreasing since the mid-1990s.
Scientists have identified two new mutations in varroa collected from Florida and Georgia, USA, that give the parasites resistance to tau-fluvalinate. The discovery of the two mutations enables testing of varroa populations to determine whether the chemical will be effective.
Rothamsted Research submitted an application on February 1st 2016 to the Department for Environment, Food and Rural Affairs for permission to carry out a GM field trial on the Rothamsted Farm in 2016 and 2017. The risk assessment was reviewed by the independent Advisory Committee on Releases to the Environment (ACRE), and a 48-day public consultation was carried out by Defra. ACRE is satisfied that all scientific issues raised by the public with respect to this application have been addressed.
Rothamsted Research has submitted an application to the Department for Environment, Food and Rural Affairs (Defra) for permission to carry out a GM field trial on the Rothamsted Farm in 2016 and 2017. Scientists at Rothamsted Research, who receive strategic funding from the Biotechnology and Biological Sciences Research Council (BBSRC), have previously trialed in the field Camelina plants that accumulate omega-3 long chain polyunsaturated fatty acids (LC-PUFAs) in their seeds.
