The impact of plant genetic variation, drought, and leaf nitrogen on plant-herbivore interactions

Plant genotype, drought stress, and their interaction are among the factors contributing to the susceptibility of plants to herbivory. The plant's nitrogen concentration, a critical and often limiting nutrient, differs with plant genotype and drought. Still, few studies have investigated the impact of the interaction of genotype and drought on herbivory and plant nitrogen. We established a common garden in Duluth, MN, of tall goldenrod, Solidago altissima, collected from a local Minnesota site to analyze the effects of goldenrod genotype and drought stress on leaf nitrogen and the preference and performance of the chrysanthemum lace bug, Corythucha marmorata. Lace bugs had oviposition, nymph, and adult preferences among host plant genotypes, water treatments, and among genotype and water treatment combinations. Nymph and adult survival and adult mass varied significantly due to plant genotype, water treatment, the interaction of plant and water treatment, and the interaction of treatmen..., , , # The impact of plant genetic variation, drought, and leaf nitrogen on plant-herbivore interactions

## DESCRIPTION OF THE DATA AND FILE STRUCTURE

ChoiceandNoChoiceExperiments.csv dataset was used to determine lace bug preference and performance among plant genotypes and water treatments in the choice and no choice experiments

Variable List

* Experiment: experimental treatment based on whether insects had a choice to colonize plants
* Genotype: unique identifier for the individual plant genotype, randomly labeled with a letter between A-T
* Water Treatment: low, moderate, or high-water treatment assigned to plant
* Adult Abundance: the number of lace bug adults
* Nymph Abundance: the number of lace bug nymphs
* Egg Number: the number of lace bug eggs
* S.Leaves (%): the percentage of senescing leaves on the plant replicate

Missing data codes: NA
