Hypothesis

What are the routes of transmission of Rickettsia and Hamiltonella from B. tabaci to the whitefly's parasitoids?

Conclusion

The study demonstrates potential routes and barriers to horizontal transmission of symbionts across trophic levels.

Supporting Evidence

  • Rickettsia was found to invade Eretmocerus larvae during development.
  • Rickettsia does not penetrate the oocytes but is localized in the follicular epithelial cells.
  • Hamiltonella did not establish in any of the parasitoids tested.

Takeaway

This study looks at how tiny bacteria can move from one insect to another, showing that some bacteria can spread easily while others can't.

Methodology

The study used fluorescence in situ hybridization (FISH) and transmission electron microscopy to investigate the transmission of symbionts.

Limitations

The study did not find evidence of vertical transmission of Rickettsia in Eretmocerus wasps.
