INVERNIZZI, Ciro. Chalkbrood disease resistance in Apis mellifera colonies with eficient hygienic behaviour (Hymenoptera, Apidae). Iheringia, Sér. Zool. [online]. 2001, n.91, pp.108-114. ISSN 0073-4721.

In an apiary composed of 14 hygienic and 7 non-hygienic colonies of Apis mellifera Linnaeus, 1758 the presence of visible and capped mummies was recorded, one hygienic and 4 non-hygienic colonies showed symptoms of chalkbrood. Twenty-eight days after a massive contamination of the colonies with pollen patties containing Ascosphaera apis Olive & Spiltoir, 1955, the situation was almost identical to that at the beginning: the same 4 non-hygienic colonies still were infected and one hygienic colony that was healthy became infected. The high proportion of hygienic colonies that eliminated the disease symptoms suggests that they could maintain themselves healthy in spite of the presence of colonies with chalkbrood in the apiary.

Keywords : Honey bees; Apis; chalkbrood; Ascosphaera; hygienic behaviour.
