Differences in gene expression and genetic variation underlying preference-performance mismatches: insights from a specialized native herbivore on an invasive toxic plant.

Abstract excerpt

Specialist phytophagous insects have a narrow hostplant range for optimal development and survival. Mismatches between female oviposition preference and larval performance can lead to high fitness costs. Understanding the mechanistic basis of this decoupling can help us understand evolutionary constraints and aid in predicting outcomes of error-prone oviposition. We investigated the causes for...
