Californian crop pests, pesticide applications, and phylogenetic information of crops Information on pesticide applications, crop pests, and phylogenetic affinities between Californian crops and regional native plants were compiled. Data was collected to inform models of pesticide applications and host use of pests among California's 93 major crops. Pesticide data was assembled from California Department of Pesticide Regulation records, pest information was assembled from the California Integrated Pest Management database, and phylogenetic affinities were based on a supertree of plants in the Jepson Manual assembled based on the Zanne et al 2014 mega-phylogeny of seed plants.

In the first experiment, parasitized caterpillars were fed artificial diets spiked with increasing concentrations of the phytochemical xanthotoxin in order to assess the effect of xanthotoxin on parasitoid success. In the second experiment, parasitized caterpillars were switched between diets with differing xanthotoxin concentration, such that all caterpillars experienced the same mean xanthotoxin concentration over their lives, but different treatments experienced different variability in xanthotoxin concentration. Data were recorded on caterpillar... Categories: Data; Tags: USGS Science Data Catalog (SDC), biota, chemical ecology, herbivory, parasitoid, All tags... top-down control, variability, Fewer tags
