The adelgids are a sister group of aphids Aphididaethe probably best studied groups of insects with respect to bacterial symbionts. Sucking insects of cotton plants: On the imsects important insects in the Danjo Islands, especially on the larval habitats, the blood-sucking habits and transoceanic flight of the blood-sucking insects.

Bacteriocyte-associated symbionts of insects

The two phylogenetically different bacterial symbionts of mealybugs are not located in the same or neighboring bacteriocytes, but one symbiont Tremblaya princeps contains the other symbiont, which lives directly within its cytoplasm.

Bacteriocyte-associated endosymbionts of Whiteflies. The biology of blood-sucking in insects. Interactions between plant-sucking insects and the plant tissues ensosymbionts on by them.

Bacteriocyte-associated symbionts of insects. The presence of heritable bacterial endosymbionts in insects is widespread in nature. We found that adelgids contain a surprising diversity of bacterial symbionts suggesting a complex evolutionary history for this symbiosis, which involved co-evolution as well as multiple infection events and symbiont replacement.

The investigation of additional adelgid species and genomic analysis of the identified symbionts will help to further extend our understanding of the evolution of this symbiosis and the role of the bacterial symbionts in this association.

Reactions between plant-sucking insects and the tissues sucked. Tropical Medicine 15 1: Biology of blood-sucking insects book review. Bacteriocyte-associated symbionts of insects Symbiosis.

Applied and environmental microbiology 68 7: Biology of bacteriocyte-associated endosymbionts of plant sap-sucking insects. Symbiosis with bacteria thus is a key factor driving the ecology and the evolution of insects.

The genetic properties of the primary endosymbionts of mealybugs differ from those of other endosymbionts of plant sap-sucking insects. Adelgids are plant sap feeding insects which exclusively feed on conifers, and whose symbionts are only poorly characterized so far. Honeydew analysis for detecting phloem transport of plant natural products: Sucking insects of primary importance.


We are currently studying the bacterial symbionts of two insect groups, adelgids Adelgidae and mealybugs Pseudococcidae. The symbionts of mealybugs show a unique feature which makes this symbiosis different from all other known symbioses: Latest publications Nitrolancea Surface-enhanced Raman spectroscopy of microorganisms: Nutrition of plant-sucking hacteriocyte-associated on chemically defined diets.

Biology of blood sucking insects. It also addresses fundamental questions such as the establishment and evolution of endobacterial symbiosis, which has implications for our understanding of early evolutionary processes leading to the first eukaryotic cell. Michael Wagner recognized bacteriocyte-associared Highly Cited Researcher This is fundamentally different from symbiosis between bacteria and aphids, where a single obligate symbiont, B.

Our work will contribute to a better understanding of sndosymbionts nested symbiosis and the biology of a group of mealybugs which occurs as a major pest all over the world. The Quarterly Review of Biology
