P. E. Howse,I. D. R. Stevens,O. T. Jonesiewed as a promising means of addressing some of these obstacles, they frequently encounter the issue of being highly research-intensive and risky investments. In this project, we pose the following question: How can we effectively design investment vehicles and strategies to support food tech start

The role of pheromones in insect behaviour and ecologyoccur. At low densities the desert locust, ., is cryptically coloured, but in high densities the insects undergo a startling colour change and they aggregate, sometimes forming swarms of hundreds of millions of insects. This phase change involves graded changes in colour, morphology, behaviour and p

Synthesis of pheromonesd on the insect, both in the laboratory and in the field. Without such a step, the structure remains a chemical curiosity, of no value either to the biologist or to the chemist, or to the agriculturalist who may wish to control the population of the insect in question. Furthermore, the synthesis is

However, it soon became apparent that these single compounds when used in isolation were not as attractive as the virgin females nor, often, as the crude extracts obtained from the
