Abstract: Several species of leafhopper are able to vector the phytoplasma that causes Cherry X-disease. In the city of The Dalles Oregon where most sweet cherries are grown the most abundant leafhopper species found is Euscelidius variegates. Having a better understanding of the phenology of this important species would help with management decisions. Phenology models can be generated by collecting large amounts of insect and weather data and fitting it with modeling software. It can also be done by painstakingly rearing insects under controlled conditions and directly observing and recording their development. Here we describe our methods and findings of this phenology project.
