Cover Story: In the UK, severe infestations by Plutella xylostella occur sporadically and are due mainly to the immigration of moths. The aim of this study was to improve warnings to growers about moth influxes. Populations were monitored using pheromone traps, by counting immature stages on plants and by accessing citizen science data. Analysis of historical weather data showed that the immediate sources of immigrant moths were countries in the western part of continental Europe. A network of pheromone traps, each containing a small camera sending images to a website, provided accessible and timely information, but the system tested did not catch many moths. In another approach, sightings by citizen scientists were summarised on a web page. These were accessed regularly by growers and, at present, this approach appears to be the most effective way of providing timely warnings. View this paper
