ASSESSING ECOLOGICAL FACILITATION BY THE SYMBIONT BUCHNERA APHIDICOLAIN GENETICALLY DISTINCT SUGARCANE APHID POPULATIONS (MELANAPHIS SACCHARI)

Objective

This research project proposes to characterize the genetic composition of both the invasive sugarcane aphid (Melanaphis sacchari, SCA) and its obligate symbiont, Buchnera aphidicola, to determine whether genetic variation in this symbiont and its insect host is responsible for differential damage potential of SCAs on grain sorghum. This project will provide a foundation for understanding the role that genetics and symbionts have in pest insects and may provide the foundation to develop new tools to manage sugarcane aphids. Research Objectives:Objective 1: Characterize genetically distinct SCA populations for use in symbiont analysisObjective 2: Sequence and annotate the obligate symbiont Buchnera aphidicola from genetically distinct SCAObjective 3: Assess Buchnera aphidicola ecological facilitation of genetically distinct SCA populations
