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
Chemical ecology research at Rothamsted exploits long established and acclaimed expertise in the identification and development of pheromones and other semiochemicals (signalling chemicals) for use in 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.

Using appropriate combinations of carefully selected companion crops, scientists at Rothamsted Research, in a collaborative project led by International Centre of Insect Physiology and Ecology (icipe), have shown how smallholder farmers in sub-Saharan Africa can increase their agricultural production amid the challenges posed by climate change.
Cabbage stem flea beetle (CSFB) damage in the 2014 year contributed to estimated losses of 2.7% of the winter oilseed rape (WOSR) area in England and Scotland, although there was significant regional variation.
In Hampshire, Bedfordshire and Hertfordshire 40% of the WOSR was reported as having damage levels at or above treatment thresholds.
Samples sent for testing at Rothamsted Research contained beetles that were strongly resistant to pyrethroids. As a result, Rothamsted is doing a follow up survey for resistance in 2015.
In a landmark paper published today in the journal Metabolic Engineering Communications, scientists at Rothamsted Research have announced the first year results of the field-scale trial of Camelina oilseed plants genetically engineered to make omega-3 fish oils in their seeds.
The results of the GM wheat field trial held by Rothamsted Research in 2012-2013 are published in the scientific journal Scientific Reports today. The data show that the GM wheat did not repel aphid pests in the field as was hypothesised and was initially seen in laboratory experiments conducted by scientists at the Institute.
Urgent research to understand the nature and extent of insecticide resistance in an increasingly damaging pest of peas and beans is underway at Rothamsted Research. The work is in response to reports of failure to control the pea and bean weevil (Sitona lineatus) with pyrethroid sprays, which are a special chemical class of active ingredients found in many modern insecticides used by growers.
Scientists at Rothamsted Research in collaboration with Cardiff University, have, through the power of a novel approach, made new insect repellent odours (or semiochemicals). The novel approach uses a combination of biological and chemical techniques to imitate a naturally occurring odour. The new, non-naturally produced odour molecules look differently but work similarly to the original, naturally occurring insect repellent odour.
Investigation and characterisation of diamide insecticide resistance conferred by target-site mutations in the ryanodine receptor of lepidopteran pests with special reference to diamondback moth, Plutella xylostella
Diamide insecticides, such as flubendiamide and chlorantraniliprole, act as conformation sensitive activators of insect ryanodine receptors (RyR), releasing calcium from intracellular stores in insect muscle, and causing an irreversible paralysis.
