Initial handling and diagnosis of diseased invertebrates

Lawrence A. Lacey, Leellen F. Solter

Research output: Chapter in Book/Report/Conference proceedingChapter


Successful implementation of microbial control has been the result of systematic surveys and exhaustive investigations on pathogen biology, host–pathogen interactions, and application techniques. Insects are associated with a broad diversity of microorganisms in a variety of symbiotic relationships including: commensalism, mutualism, and parasitism. Entomopathogens result in a variety of conditions in host insects that are subtly to distinctly unfavorable to the host. This chapter will provide general guidelines and protocols for: collection of entomopathogens and diseased invertebrates; examination in the laboratory; identification of the major entomopathogen groups; conclusive diagnosis—satisfying Koch's postulates; and safety considerations. The techniques presented in this chapter are supplemented with updated literature and new information.
