On the system by which sandflies maintain a sterile gut

  • Y. Schlein (a1), A. Warburg (a1) and B. Yuval (a1)


This paper combines some of the results from three studies that explain the system by which the gut of Phlebotomus papatasi is maintained bacteria free. This system includes an antibacterial factor in the crop (diverticulum) and feeding behaviour which determines selective routing of meals. When feeding by piercing animal skin or plant tissue, in a ‘blood feeding’ mode, the uncontaminated meals of both sources enter the midgut directly. Free-solution sugar-meals which may contain contaminants, enter the crop where they mix with the antibacterial agent. Feeding on plants is also described.

Les résultats de trois études cherchant à expliquer comment le tube digestif de Phlebotomus papatasi est maintenu stérile sont présentés dans ce travail. Cette stérilité, résulte de l'existence d'un facteur antibactérien présent dans le diverticulum et d'un comportement alimentaire qui oriente differentiellement les repas. Quant on nourrit les phlébotomes selon le mode d'un repas de sang (peau d'animal ou végétaux) le repas non contaminé est dirigé directement vers l'estomac. A l'opposé un repas donné sous forme de liquide (glucides) contaminé ou non est dirigé vers le diverticulum où il se mélange avec le facteur antibacterien. Le repas de Phlebotomus papatasi sur les plantes est décrit.
