Area of Science:

  • Insect immunology
  • Molecular biology
  • Quantitative genetics

Background:

  • Honey bees and other insects possess complex defenses against parasites and pathogens.
  • Understanding these defense mechanisms is crucial for bee health and survival.
  • Existing methods for studying immune responses can be limited in scope and throughput.

Purpose of the Study:

  • To develop and validate a quantitative-PCR array for assessing honey bee immune gene expression.
  • To measure the responsiveness of honey bee immune genes to various pathogens.
  • To provide a tool for dissecting the genetic and environmental influences on bee immunity.

Main Methods:

  • Development of a custom quantitative-PCR array targeting 48 honey bee and pathogen genes.
  • Parallel measurement of host and pathogen transcript levels using SYBR-Green chemistry.
